- * A Scrollable Text Output Window

- * David Harrison
- * University of California, Berkeley
- * 1986
- *
- * The following is an implementation for a scrollable text output
- * system. It handles exposure events only (other interactions are
- * under user control). For scrolling, a always present scroll bar
- * is implemented. It detects size changes and compensates accordingly.

-.TH Chess GNU
-.SH NAME
-Chess \- GNU Chess
-.SH SYNOPSIS
-.B Chess
-[
-.B arg1 arg2
-]
-.SH DESCRIPTION
-.I Chess
-plays a game of chess against the user or it plays against itself.
-.PP
-.I Chess
-has a simple alpha-numeric board display or it can be compiled for
-use with the CHESSTOOL program on a SUN workstation.
-The program gets its opening moves from the file gnuchess.book which
-should be located in the same directory as gnuchess.
-To invoke the prgram, type 'gnuchess' or type 'chesstool gnuchess'
-on a SUN workstation where 'CHESSTOOL' is installed.
-The 'gnuchess' command can be followed by up to 2 command line arguments.
-If one argument is given it determines the programs search time in
-seconds. If two arguments are given, they will be used to set tournament
-time controls with the first argument being the number of moves and the second
-being the total clock time in minutes. Thus, entering 'chess 60 5' will set
-the clocks for 5 minutes (300 seconds) for the first 60 moves.
-If no argument is given the program will prompt the user for level of
-play.
-For use with CHESSTOOL, see the documentation on that program.
-.PP
-Once
-.I Chess
-is invoked, the program will display the board and prompt the user
-for a move. To enter a move, use the notation 'e2e4' where the first
-letter-number pair indicates the origination square
-and the second letter-number pair indicates the destination square.
-An alternative is to use the notation 'nf3' where
-the first letter indicates the piece type (p,n,b,r,q,k).
-To castle, type the origin and destination squares
-of the king just as you would do for a regular move, or type
-"o-o" for kingside castling and "o-o-o" for queenside.
-.SH COMMANDS
-.PP
-In addition to legal moves, the following commands are available as responses.
-.PP
-.I beep
--- causes the program to beep after each move.
-.PP
-.I bd
--- updates the current board position on the display.
-.PP
-.I book
--- turns off use of the opening library.
-.PP
-.I both
--- causes the computer to play both sides of a chess game.
-.PP
-.I black
--- causes the computer to take the black pieces with the move
-and begin searching.
-.PP
-.I level
--- allows the user to set time controls such as
-60 moves in 5 minutes etc. In tournament mode, the program will
-vary the time it takes for each
-move depending on the situation. If easy mode is disabled (using
-the 'easy' command), the program
-will often respond with its move immediately, saving time on
-its clock for use later on.
-.PP
-.I depth
--- allows the user to change the
-search depth of the program. The maximum depth is 29 ply.
-Normally the depth is set to 29 and the computer terminates
-its search based on elapsed time rather than depth.
-Using the depth command allows setting depth to say
-4 ply and setting response time to a large number such as
-9999 seconds. The program will then search until all moves
-have been examined to a depth of 4 ply (with extensions up
-to 11 additional ply for sequences of checks and captures).
-.PP
-.I easy
--- toggles easy mode (thinking on opponents time)
-on and off. The default is easy mode ON. If easy mode is disabled,
-the user must enter a 'break' or '^C' to get the programs
-attention before entering each move.
-.PP
-.I edit
--- allows the user to set up a board position.
-In this mode, the '#' command will clear the board, the 'c'
-command will toggle piece color, and the '.' command will exit
-setup mode. Pieces are entered by typing a letter (p,n,b,r,q,k) for
-the piece followed by the coordinate. For example "pb3" would
-place a pawn on square b3.
-.PP
-.I force
--- allows the user to enter moves for both
-sides. To get the program to play after a sequence of moves
-has been entered use the 'white' or 'black' commands.
-.PP
-.I get
--- retrieves a game from disk. The program will
-prompt the user for a file name.
-.PP
-.I help
--- displays a short description of the commands.
-.PP
-.I hint
--- causes the program to supply the user with
-its predicted move.
-.PP
-.I list
--- writes the game moves and some statistics
-on search depth, nodes, and time to the file 'chess.lst'.
-.PP
-.I new
--- starts a new game.
-.PP
-.I post
--- causes the program to display the principle
-variation and the score during the search. A score of
-100 is equivalent to a 1 pawn advantage for the computer.
-.PP
-.I random
--- causes the program to randomize its move
-selection slightly.
-.PP
-.I reverse
--- causes the board display to be reversed. That
-is, the white pieces will now appear at the top of the board.
-.PP
-.I quit
--- exits the game.
-.PP
-.I save
--- saves a game to disk. The program will prompt
-the user for a file name.
-.PP
-.I switch
--- causes the program to switch places with
-the opponent and begin searching.
-.PP
-.I undo
--- undoes the last move whether it was the computer's
-or the human's. You may also type "remove". This is equivalent
-to two "undo's" (e.g. retract one move for each side).
-.PP
-.I white
--- causes the computer to take the white pieces
-with the move and begin searching.
-.SH BUGS
-.PP
-Pawn promotion to pieces other than a queen is not allowed.
-En-Passant does not work properly with CHESSTOOOL.
-The transposition table may not work properly in some
-positions so the default is to turn this off.

-Using History Interactively
-***************************
-
- This chapter describes how to use the GNU History Library
-interactively, from a user's standpoint. It should be considered a
-user's guide. For information on using the GNU History Library in your
-own programs, *note Programming with GNU History::..

-
-History Interaction
-===================
-
- The History library provides a history expansion feature that is
-similar to the history expansion provided by `csh'. The following text
-describes the syntax used to manipulate the history information.
-
- History expansion takes place in two parts. The first is to
-determine which line from the previous history should be used during
-substitution. The second is to select portions of that line for
-inclusion into the current one. The line selected from the previous
-history is called the "event", and the portions of that line that are
-acted upon are called "words". The line is broken into words in the
-same fashion that Bash does, so that several English (or Unix) words
-surrounded by quotes are considered as one word.
-
-* Menu:
-
-* Event Designators:: How to specify which history line to use.
-* Word Designators:: Specifying which words are of interest.
-* Modifiers:: Modifying the results of substitution.
-

-
-Event Designators
------------------
-
- An event designator is a reference to a command line entry in the
-history list.

-Introduction to History
-=======================
-
- Many programs read input from the user a line at a time. The GNU
-History library is able to keep track of those lines, associate
-arbitrary data with each line, and utilize information from previous
-lines in composing new ones.
-
- The programmer using the History library has available functions for
-remembering lines on a history list, associating arbitrary data with a
-line, removing lines from the list, searching through the list for a
-line containing an arbitrary text string, and referencing any line in
-the list directly. In addition, a history "expansion" function is
-available which provides for a consistent user interface across
-different programs.
-
- The user using programs written with the History library has the
-benefit of a consistent user interface with a set of well-known
-commands for manipulating the text of previous lines and using that text
-in new commands. The basic history manipulation commands are similar to
-the history substitution provided by `csh'.
-
- If the programmer desires, he can use the Readline library, which
-includes some history manipulation by default, and has the added
-advantage of command line editing.
-
-
-File: history.info, Node: History Storage, Next: History Functions, Prev: Introduction to History, Up: Programming with GNU History
-
-History Storage
-===============
-
- The history list is an array of history entries. A history entry is
-declared as follows:
-
- typedef struct _hist_entry {
- char *line;
- char *data;
- } HIST_ENTRY;
-
- The history list itself might therefore be declared as
-
- HIST_ENTRY **the_history_list;
-
- The state of the History library is encapsulated into a single
-structure:
-
- /* A structure used to pass the current state of the history stuff around. */
- typedef struct _hist_state {
- HIST_ENTRY **entries; /* Pointer to the entries themselves. */
- int offset; /* The location pointer within this array. */
- int length; /* Number of elements within this array. */
- int size; /* Number of slots allocated to this array. */
- int flags;
- } HISTORY_STATE;
-
- If the flags member includes `HS_STIFLED', the history has been
-stifled.

- This section describes functions used to initialize and manage the
-state of the History library when you want to use the history functions
-in your program.
-
- - Function: void using_history ()
- Begin a session in which the history functions might be used. This
- initializes the interactive variables.
-
- - Function: HISTORY_STATE * history_get_history_state ()
- Return a structure describing the current state of the input
- history.

-
-
-File: history.info, Node: History List Management, Next: Information About the History List, Prev: Initializing History and State Management, Up: History Functions
-
-History List Management
------------------------
-
- These functions manage individual entries on the history list, or set
-parameters managing the list itself.
-
- - Function: void add_history (char *string)
- Place STRING at the end of the history list. The associated data
- field (if any) is set to `NULL'.
-
- - Function: HIST_ENTRY * remove_history (int which)
- Remove history entry at offset WHICH from the history. The
- removed element is returned so you can free the line, data, and
- containing structure.
-
- - Function: HIST_ENTRY * replace_history_entry (int which, char *line,
- char *data)
- Make the history entry at offset WHICH have LINE and DATA. This
- returns the old entry so you can dispose of the data. In the case
- of an invalid WHICH, a `NULL' pointer is returned.
-
- - Function: void stifle_history (int max)
- Stifle the history list, remembering only the last MAX entries.
-
- - Function: int unstifle_history ()
- Stop stifling the history. This returns the previous amount the
- history was stifled. The value is positive if the history was
- stifled, negative if it wasn't.
-
- - Function: int history_is_stifled ()
- Returns non-zero if the history is stifled, zero if it is not.
-
-
-File: history.info, Node: Information About the History List, Next: Moving Around the History List, Prev: History List Management, Up: History Functions
-
-Information About the History List
-----------------------------------
-
- These functions return information about the entire history list or
-individual list entries.
-
- - Function: HIST_ENTRY ** history_list ()
- Return a `NULL' terminated array of `HIST_ENTRY' which is the
- current input history. Element 0 of this list is the beginning of
- time. If there is no history, return `NULL'.
-
- - Function: int where_history ()
- Returns the offset of the current history element.
-
- - Function: HIST_ENTRY * current_history ()
- Return the history entry at the current position, as determined by
- `where_history ()'. If there is no entry there, return a `NULL'
- pointer.
-
- - Function: HIST_ENTRY * history_get (int offset)
- Return the history entry at position OFFSET, starting from
- `history_base'. If there is no entry there, or if OFFSET is
- greater than the history length, return a `NULL' pointer.
-
- - Function: int history_total_bytes ()
- Return the number of bytes that the primary history entries are
- using. This function returns the sum of the lengths of all the
- lines in the history.
-
-
-File: history.info, Node: Moving Around the History List, Next: Searching the History List, Prev: Information About the History List, Up: History Functions
-
-Moving Around the History List
-------------------------------
-
- These functions allow the current index into the history list to be
-set or changed.
-
- - Function: int history_set_pos (int pos)
- Set the position in the history list to POS, an absolute index
- into the list.
-
- - Function: HIST_ENTRY * previous_history ()
- Back up the current history offset to the previous history entry,
- and return a pointer to that entry. If there is no previous
- entry, return a `NULL' pointer.
-
- - Function: HIST_ENTRY * next_history ()
- Move the current history offset forward to the next history entry,
- and return the a pointer to that entry. If there is no next
- entry, return a `NULL' pointer.
-
-
-File: history.info, Node: Searching the History List, Next: Managing the History File, Prev: Moving Around the History List, Up: History Functions
-
-Searching the History List
---------------------------
-
- These functions allow searching of the history list for entries
-containing a specific string. Searching may be performed both forward
-and backward from the current history position. The search may be
-"anchored", meaning that the string must match at the beginning of the
-history entry.
-
- - Function: int history_search (char *string, int direction)
- Search the history for STRING, starting at the current history
- offset. If DIRECTION < 0, then the search is through previous
- entries, else through subsequent. If STRING is found, then the
- current history index is set to that history entry, and the value
- returned is the offset in the line of the entry where STRING was
- found. Otherwise, nothing is changed, and a -1 is returned.
-
- - Function: int history_search_prefix (char *string, int direction)
- Search the history for STRING, starting at the current history
- offset. The search is anchored: matching lines must begin with
- STRING. If DIRECTION < 0, then the search is through previous
- entries, else through subsequent. If STRING is found, then the
- current history index is set to that entry, and the return value
- is 0. Otherwise, nothing is changed, and a -1 is returned.
-
- - Function: int history_search_pos (char *string, int direction, int
- pos)
- Search for STRING in the history list, starting at POS, an
- absolute index into the list. If DIRECTION is negative, the search
- proceeds backward from POS, otherwise forward. Returns the
- absolute index of the history element where STRING was found, or
- -1 otherwise.

-
-Managing the History File
--------------------------
-
- The History library can read the history from and write it to a file.
-This section documents the functions for managing a history file.
-
- - Function: int read_history (char *filename)
- Add the contents of FILENAME to the history list, a line at a
- time. If FILENAME is `NULL', then read from `~/.history'.
- Returns 0 if successful, or errno if not.
-
- - Function: int read_history_range (char *filename, int from, int to)
- Read a range of lines from FILENAME, adding them to the history
- list. Start reading at line FROM and end at TO. If FROM is zero,
- start at the beginning. If TO is less than FROM, then read until
- the end of the file. If FILENAME is `NULL', then read from
- `~/.history'. Returns 0 if successful, or `errno' if not.
-
- - Function: int write_history (char *filename)
- Write the current history to FILENAME, overwriting FILENAME if
- necessary. If FILENAME is `NULL', then write the history list to
- `~/.history'. Values returned are as in `read_history ()'.
-
- - Function: int append_history (int nelements, char *filename)
- Append the last NELEMENTS of the history list to FILENAME.
-
- - Function: int history_truncate_file (char *filename, int nlines)
- Truncate the history file FILENAME, leaving only the last NLINES
- lines.
-
-
-File: history.info, Node: History Expansion, Prev: Managing the History File, Up: History Functions
-
-History Expansion
------------------
-
- These functions implement `csh'-like history expansion.
-
- - Function: int history_expand (char *string, char **output)
- Expand STRING, placing the result into OUTPUT, a pointer to a
- string (*note History Interaction::.). Returns:
- `0'
- If no expansions took place (or, if the only change in the
- text was the de-slashifying of the history expansion
- character);
-
- `1'
- if expansions did take place;
-
- `-1'
- if there was an error in expansion;
-
- `2'
- if the returned line should only be displayed, but not
- executed, as with the `:p' modifier (*note Modifiers::.).
-
- If an error ocurred in expansion, then OUTPUT contains a
- descriptive error message.
-
- - Function: char * history_arg_extract (int first, int last, char
- *string)
- Extract a string segment consisting of the FIRST through LAST
- arguments present in STRING. Arguments are broken up as in Bash.
-
- - Function: char * get_history_event (char *string, int *cindex, int
- qchar)
- Returns the text of the history event beginning at STRING +
- *CINDEX. *CINDEX is modified to point to after the event
- specifier. At function entry, CINDEX points to the index into
- STRING where the history event specification begins. QCHAR is a
- character that is allowed to end the event specification in
- addition to the "normal" terminating characters.
-
- - Function: char ** history_tokenize (char *string)
- Return an array of tokens parsed out of STRING, much as the shell
- might. The tokens are split on white space and on the characters
- `()<>;&|$', and shell quoting conventions are obeyed.

-History Variables
-=================
-
- This section describes the externally visible variables exported by
-the GNU History Library.
-
- - Variable: int history_base
- The logical offset of the first entry in the history list.
-
- - Variable: int history_length
- The number of entries currently stored in the history list.
-
- - Variable: int max_input_history
- The maximum number of history entries. This must be changed using
- `stifle_history ()'.
-
- - Variable: char history_expansion_char
- The character that starts a history event. The default is `!'.
-
- - Variable: char history_subst_char
- The character that invokes word substitution if found at the start
- of a line. The default is `^'.
-
- - Variable: char history_comment_char
- During tokenization, if this character is seen as the first
- character of a word, then it and all subsequent characters up to a
- newline are ignored, suppressing history expansion for the
- remainder of the line. This is disabled by default.
-
- - Variable: char * history_no_expand_chars
- The list of characters which inhibit history expansion if found
- immediately following HISTORY_EXPANSION_CHAR. The default is
- whitespace and `='.

-
-The History library provides a history expansion feature that is similar

-that you use to manipulate the history information.
-
-History expansion takes place in two parts. The first is to determine
-which line from the previous history should be used during substitution.
-The second is to select portions of that line for inclusion into the
-current one. The line selected from the previous history is called the
-@dfn{event}, and the portions of that line that are acted upon are
-called @dfn{words}. The line is broken into words in the same fashion
-that the Bash shell does, so that several English (or Unix) words
-surrounded by quotes are considered as one word.

-Introduction to Line Editing
-============================
-
- The following paragraphs describe the notation used to represent
-keystrokes.
-
- The text C-k is read as `Control-K' and describes the character
-produced when the Control key is depressed and the k key is struck.
-
- The text M-k is read as `Meta-K' and describes the character
-produced when the meta key (if you have one) is depressed, and the k
-key is struck. If you do not have a meta key, the identical keystroke
-can be generated by typing ESC first, and then typing k. Either
-process is known as "metafying" the k key.
-
- The text M-C-k is read as `Meta-Control-k' and describes the
-character produced by "metafying" C-k.
-
- In addition, several keys have their own names. Specifically, DEL,
-ESC, LFD, SPC, RET, and TAB all stand for themselves when seen in this
-text, or in an init file (*note Readline Init File::., for more info).

-
-Readline Interaction
-====================
-
- Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled. The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line. Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections. Then, when you are satisfied with
-the line, you simply press RETURN. You do not have to be at the end of
-the line to press RETURN; the entire line is accepted regardless of the
-location of the cursor within the line.

-
-Readline Bare Essentials
-------------------------
-
- In order to enter characters into the line, simply type them. The
-typed character appears where the cursor was, and then the cursor moves
-one space to the right. If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
- Sometimes you may miss typing a character that you wanted to type,
-and not notice your error until you have typed several other
-characters. In that case, you can type C-b to move the cursor to the
-left, and then correct your mistake. Afterwards, you can move the
-cursor to the right with C-f.
-
- When you add text in the middle of a line, you will notice that
-characters to the right of the cursor are `pushed over' to make room
-for the text that you have inserted. Likewise, when you delete text
-behind the cursor, characters to the right of the cursor are `pulled
-back' to fill in the blank space created by the removal of the text. A
-list of the basic bare essentials for editing the text of an input line
-follows.
-
-C-b
- Move back one character.
-
-C-f
- Move forward one character.
-
-DEL
- Delete the character to the left of the cursor.
-
-C-d
- Delete the character underneath the cursor.
-
-Printing characters
- Insert the character into the line at the cursor.
-
-C-_
- Undo the last thing that you did. You can undo all the way back
- to an empty line.
-

-
-Readline Movement Commands
---------------------------
-
- The above table describes the most basic possible keystrokes that
-you need in order to do editing of the input line. For your
-convenience, many other commands have been added in addition to C-b,
-C-f, C-d, and DEL. Here are some commands for moving more rapidly
-about the line.
-
-C-a
- Move to the start of the line.
-
-C-e
- Move to the end of the line.
-
-M-f
- Move forward a word.
-
-M-b
- Move backward a word.
-
-C-l
- Clear the screen, reprinting the current line at the top.
-
- Notice how C-f moves forward a character, while M-f moves forward a
-word. It is a loose convention that control keystrokes operate on
-characters while meta keystrokes operate on words.

-File: readline.info, Node: Readline Killing Commands, Next: Readline Arguments, Prev: Readline Movement Commands, Up: Readline Interaction
-
-Readline Killing Commands
--------------------------
-
- "Killing" text means to delete the text from the line, but to save
-it away for later use, usually by "yanking" (re-inserting) it back into
-the line. If the description for a command says that it `kills' text,
-then you can be sure that you can get the text back in a different (or
-the same) place later.
-
- When you use a kill command, the text is saved in a "kill-ring".
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all. The kill ring is not line
-specific; the text that you killed on a previously typed line is
-available to be yanked back later, when you are typing another line.
-
- Here is the list of commands for killing text.
-
-C-k
- Kill the text from the current cursor position to the end of the
- line.
-
-M-d
- Kill from the cursor to the end of the current word, or if between
- words, to the end of the next word.
-
-M-DEL
- Kill from the cursor the start of the previous word, or if between
- words, to the start of the previous word.
-
-C-w
- Kill from the cursor to the previous whitespace. This is
- different than M-DEL because the word boundaries differ.
-
- And, here is how to "yank" the text back into the line. Yanking
-means to copy the most-recently-killed text from the kill buffer.
-
-C-y
- Yank the most recently killed text back into the buffer at the
- cursor.
-
-M-y
- Rotate the kill-ring, and yank the new top. You can only do this
- if the prior command is C-y or M-y.
-
-
-File: readline.info, Node: Readline Arguments, Prev: Readline Killing Commands, Up: Readline Interaction
-
-Readline Arguments
-------------------
-
- You can pass numeric arguments to Readline commands. Sometimes the
-argument acts as a repeat count, other times it is the sign of the
-argument that is significant. If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction. For example, to kill text back to the
-start of the line, you might type M- C-k.
-
- The general way to pass numeric arguments to a command is to type
-meta digits before the command. If the first `digit' you type is a
-minus sign (-), then the sign of the argument will be negative. Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command. For example, to give
-the C-d command an argument of 10, you could type M-1 0 C-d.

-
-Readline Init File
-==================
-
- Although the Readline library comes with a set of Emacs-like
-keybindings installed by default, it is possible that you would like to
-use a different set of keybindings. You can customize programs that
-use Readline by putting commands in an "init" file in your home
-directory. The name of this file is taken from the value of the
-environment variable `INPUTRC'. If that variable is unset, the default
-is `~/.inputrc'.
-
- When a program which uses the Readline library starts up, the init
-file is read, and the key bindings are set.
-
- In addition, the `C-x C-r' command re-reads this init file, thus
-incorporating any changes that you might have made to it.
-
-* Menu:
-
-* Readline Init Syntax:: Syntax for the commands in the inputrc file.
-* Conditional Init Constructs:: Conditional key bindings in the inputrc file.
-
-
-File: readline.info, Node: Readline Init Syntax, Next: Conditional Init Constructs, Up: Readline Init File
-
-Readline Init Syntax
---------------------
-
- There are only a few basic constructs allowed in the Readline init
-file. Blank lines are ignored. Lines beginning with a # are comments.
-Lines beginning with a $ indicate conditional constructs (*note
-Conditional Init Constructs::.). Other lines denote variable settings
-and key bindings.
-
-Variable Settings
- You can change the state of a few variables in Readline by using
- the `set' command within the init file. Here is how you would
- specify that you wish to use `vi' line editing commands:
-
- set editing-mode vi
-
- Right now, there are only a few variables which can be set; so
- few, in fact, that we just list them here:
-
- `editing-mode'
- The `editing-mode' variable controls which editing mode you
- are using. By default, Readline starts up in Emacs editing
- mode, where the keystrokes are most similar to Emacs. This
- variable can be set to either `emacs' or `vi'.
-
- `horizontal-scroll-mode'
- This variable can be set to either `On' or `Off'. Setting it
- to `On' means that the text of the lines that you edit will
- scroll horizontally on a single screen line when they are
- longer than the width of the screen, instead of wrapping onto
- a new screen line. By default, this variable is set to `Off'.
-
- `mark-modified-lines'
- This variable, when set to `On', says to display an asterisk
- (`*') at the start of history lines which have been modified.
- This variable is `off' by default.
-
- `bell-style'
- Controls what happens when Readline wants to ring the
- terminal bell. If set to `none', Readline never rings the
- bell. If set to `visible', Readline uses a visible bell if
- one is available. If set to `audible' (the default),
- Readline attempts to ring the terminal's bell.
-
- `comment-begin'
- The string to insert at the beginning of the line when the
- `vi-comment' command is executed. The default value is `"#"'.
-
- `meta-flag'
- If set to `on', Readline will enable eight-bit input (it will
- not strip the eighth bit from the characters it reads),
- regardless of what the terminal claims it can support. The
- default value is `off'.
-
- `convert-meta'
- If set to `on', Readline will convert characters with the
- eigth bit set to an ASCII key sequence by stripping the eigth
- bit and prepending an ESC character, converting them to a
- meta-prefixed key sequence. The default value is `on'.
-
- `output-meta'
- If set to `on', Readline will display characters with the
- eighth bit set directly rather than as a meta-prefixed escape
- sequence. The default is `off'.
-
- `completion-query-items'
- The number of possible completions that determines when the
- user is asked whether he wants to see the list of
- possibilities. If the number of possible completions is
- greater than this value, Readline will ask the user whether
- or not he wishes to view them; otherwise, they are simply
- listed. The default limit is `100'.
-
- `keymap'
- Sets Readline's idea of the current keymap for key binding
- commands. Acceptable `keymap' names are `emacs',
- `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move',
- `vi-command', and `vi-insert'. `vi' is equivalent to
- `vi-command'; `emacs' is equivalent to `emacs-standard'. The
- default value is `emacs'. The value of the `editing-mode'
- variable also affects the default keymap.
-
- `show-all-if-ambiguous'
- This alters the default behavior of the completion functions.
- If set to `on', words which have more than one possible
- completion cause the matches to be listed immediately instead
- of ringing the bell. The default value is `off'.
-
- `expand-tilde'
- If set to `on', tilde expansion is performed when Readline
- attempts word completion. The default is `off'.
-
-Key Bindings
- The syntax for controlling key bindings in the init file is
- simple. First you have to know the name of the command that you
- want to change. The following pages contain tables of the command
- name, the default keybinding, and a short description of what the
- command does.
-
- Once you know the name of the command, simply place the name of
- the key you wish to bind the command to, a colon, and then the
- name of the command on a line in the init file. The name of the
- key can be expressed in different ways, depending on which is most
- comfortable for you.
-
- KEYNAME: FUNCTION-NAME or MACRO
- KEYNAME is the name of a key spelled out in English. For
- example:
- Control-u: universal-argument
- Meta-Rubout: backward-kill-word
- Control-o: ">&output"
-
- In the above example, `C-u' is bound to the function
- `universal-argument', and `C-o' is bound to run the macro
- expressed on the right hand side (that is, to insert the text
- `>&output' into the line).
-
- "KEYSEQ": FUNCTION-NAME or MACRO
- KEYSEQ differs from KEYNAME above in that strings denoting an
- entire key sequence can be specified, by placing the key
- sequence in double quotes. Some GNU Emacs style key escapes
- can be used, as in the following example, but the special
- character names are not recognized.
-
- "\C-u": universal-argument
- "\C-x\C-r": re-read-init-file
- "\e[11~": "Function Key 1"
-
- In the above example, `C-u' is bound to the function
- `universal-argument' (just as it was in the first example),
- `C-x C-r' is bound to the function `re-read-init-file', and
- `ESC [ 1 1 ~' is bound to insert the text `Function Key 1'.
- The following escape sequences are available when specifying
- key sequences:
-
- ``\C-''
- control prefix
-
- ``\M-''
- meta prefix
-
- ``\e''
- an escape character
-
- ``\\''
- backslash
-
- ``\"''
- "
-
- ``\'''
- '
-
- When entering the text of a macro, single or double quotes
- should be used to indicate a macro definition. Unquoted text
- is assumed to be a function name. Backslash will quote any
- character in the macro text, including " and '. For example,
- the following binding will make `C-x \' insert a single \
- into the line:
- "\C-x\\": "\\"

-
-Conditional Init Constructs
----------------------------
-
- Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key bindings
-and variable settings to be performed as the result of tests. There
-are three parser directives used.
-
-`$if'
- The `$if' construct allows bindings to be made based on the
- editing mode, the terminal being used, or the application using
- Readline. The text of the test extends to the end of the line; no
- characters are required to isolate it.
-
- `mode'
- The `mode=' form of the `$if' directive is used to test
- whether Readline is in `emacs' or `vi' mode. This may be
- used in conjunction with the `set keymap' command, for
- instance, to set bindings in the `emacs-standard' and
- `emacs-ctlx' keymaps only if Readline is starting out in
- `emacs' mode.
-
- `term'
- The `term=' form may be used to include terminal-specific key
- bindings, perhaps to bind the key sequences output by the
- terminal's function keys. The word on the right side of the
- `=' is tested against the full name of the terminal and the
- portion of the terminal name before the first `-'. This
- allows SUN to match both SUN and SUN-CMD, for instance.
-
- `application'
- The APPLICATION construct is used to include
- application-specific settings. Each program using the
- Readline library sets the APPLICATION NAME, and you can test
- for it. This could be used to bind key sequences to
- functions useful for a specific program. For instance, the
- following command adds a key sequence that quotes the current
- or previous word in Bash:
- $if bash
- # Quote the current or previous word
- "\C-xq": "\eb\"\ef\""
- $endif
-
-`$endif'
- This command, as you saw in the previous example, terminates an
- `$if' command.
-
-`$else'
- Commands in this branch of the `$if' directive are executed if the
- test fails.

-
-File: readline.info, Node: Readline vi Mode, Prev: Bindable Readline Commands, Up: Command Line Editing
-
-Readline vi Mode
-================
-
- While the Readline library does not have a full set of `vi' editing
-functions, it does contain enough to allow simple editing of the line.
-The Readline `vi' mode behaves as specified in the Posix 1003.2
-standard.
-
- In order to switch interactively between `Emacs' and `Vi' editing
-modes, use the command M-C-j (toggle-editing-mode). The Readline
-default is `emacs' mode.
-
- When you enter a line in `vi' mode, you are already placed in
-`insertion' mode, as if you had typed an `i'. Pressing ESC switches
-you into `command' mode, where you can edit the text of the line with
-the standard `vi' movement keys, move to previous history lines with
-`k', and following lines with `j', and so forth.

- This document describes the GNU Readline Library, a utility for
-aiding in the consitency of user interface across discrete programs
-that need to provide a command line interface.

-Programming with GNU Readline
-*****************************
-
- This chapter describes the interface between the GNU Readline
-Library and other programs. If you are a programmer, and you wish to
-include the features found in GNU Readline such as completion, line
-editing, and interactive history manipulation in your own programs,
-this section is for you.
-
-* Menu:
-
-* Basic Behavior:: Using the default behavior of Readline.
-* Custom Functions:: Adding your own functions to Readline.
-* Readline Convenience Functions:: Functions which Readline supplies to
- aid in writing your own
-* Custom Completers:: Supplanting or supplementing Readline's
- completion functions.
-
-
-File: readline.info, Node: Basic Behavior, Next: Custom Functions, Up: Programming with GNU Readline
-
-Basic Behavior
-==============
-
- Many programs provide a command line interface, such as `mail',
-`ftp', and `sh'. For such programs, the default behaviour of Readline
-is sufficient. This section describes how to use Readline in the
-simplest way possible, perhaps to replace calls in your code to
-`gets()' or `fgets ()'.
-
- The function `readline ()' prints a prompt and then reads and returns
-a single line of text from the user. The line `readline' returns is
-allocated with `malloc ()'; you should `free ()' the line when you are
-done with it. The declaration for `readline' in ANSI C is
-
- `char *readline (char *PROMPT);'
-
-So, one might say
- `char *line = readline ("Enter a line: ");'
-
-in order to read a line of text from the user. The line returned has
-the final newline removed, so only the text remains.
-
- If `readline' encounters an `EOF' while reading the line, and the
-line is empty at that point, then `(char *)NULL' is returned.
-Otherwise, the line is ended just as if a newline had been typed.
-
- If you want the user to be able to get at the line later, (with C-p
-for example), you must call `add_history ()' to save the line away in a
-"history" list of such lines.
-
- `add_history (line)';
-
-For full details on the GNU History Library, see the associated manual.
-
- It is preferable to avoid saving empty lines on the history list,
-since users rarely have a burning need to reuse a blank line. Here is
-a function which usefully replaces the standard `gets ()' library
-function, and has the advantage of no static buffer to overflow:
-
- /* A static variable for holding the line. */
- static char *line_read = (char *)NULL;
-
- /* Read a string, and return a pointer to it. Returns NULL on EOF. */
- char *
- rl_gets ()
- {
- /* If the buffer has already been allocated, return the memory
- to the free pool. */
- if (line_read)
- {
- free (line_read);
- line_read = (char *)NULL;
- }
-
- /* Get a line from the user. */
- line_read = readline ("");
-
- /* If the line has any text in it, save it on the history. */
- if (line_read && *line_read)
- add_history (line_read);
-
- return (line_read);
- }
-
- This function gives the user the default behaviour of TAB
-completion: completion on file names. If you do not want Readline to
-complete on filenames, you can change the binding of the TAB key with
-`rl_bind_key ()'.
-
- `int rl_bind_key (int KEY, int (*FUNCTION)());'
-
- `rl_bind_key ()' takes two arguments: KEY is the character that you
-want to bind, and FUNCTION is the address of the function to call when
-KEY is pressed. Binding TAB to `rl_insert ()' makes TAB insert itself.
-`rl_bind_key ()' returns non-zero if KEY is not a valid ASCII character
-code (between 0 and 255).
-
- Thus, to disable the default TAB behavior, the following suffices:
- `rl_bind_key ('\t', rl_insert);'
-
- This code should be executed once at the start of your program; you
-might write a function called `initialize_readline ()' which performs
-this and other desired initializations, such as installing custom
-completers (*note Custom Completers::.).

-
-Custom Functions
-================
-
- Readline provides many functions for manipulating the text of the
-line, but it isn't possible to anticipate the needs of all programs.
-This section describes the various functions and variables defined
-within the Readline library which allow a user program to add
-customized functionality to Readline.
-
-* Menu:
-
-* The Function Type:: C declarations to make code readable.
-* Function Writing:: Variables and calling conventions.
-
-
-File: readline.info, Node: The Function Type, Next: Function Writing, Up: Custom Functions
-
-The Function Type
------------------
-
- For readabilty, we declare a new type of object, called "Function".
-A `Function' is a C function which returns an `int'. The type
-declaration for `Function' is:
-
-`typedef int Function ();'
-
- The reason for declaring this new type is to make it easier to write
-code describing pointers to C functions. Let us say we had a variable
-called FUNC which was a pointer to a function. Instead of the classic
-C declaration
-
- `int (*)()func;'
-
-we may write
-
- `Function *func;'
-
-Similarly, there are
-
- typedef void VFunction ();
- typedef char *CPFunction (); and
- typedef char **CPPFunction ();
-
-for functions returning no value, `pointer to char', and `pointer to
-pointer to char', respectively.
-
-
-File: readline.info, Node: Function Writing, Prev: The Function Type, Up: Custom Functions
-
-Writing a New Function
-----------------------
-
- In order to write new functions for Readline, you need to know the
-calling conventions for keyboard-invoked functions, and the names of the
-variables that describe the current state of the line read so far.
-
- The calling sequence for a command `foo' looks like
-
- `foo (int count, int key)'
-
-where COUNT is the numeric argument (or 1 if defaulted) and KEY is the
-key that invoked this function.
-
- It is completely up to the function as to what should be done with
-the numeric argument. Some functions use it as a repeat count, some as
-a flag, and others to choose alternate behavior (refreshing the current
-line as opposed to refreshing the screen, for example). Some choose to
-ignore it. In general, if a function uses the numeric argument as a
-repeat count, it should be able to do something useful with both
-negative and positive arguments. At the very least, it should be aware
-that it can be passed a negative argument.
-
- - Variable: char * rl_line_buffer
- This is the line gathered so far. You are welcome to modify the
- contents of the line, but see *Note Allowing Undoing::.
-
- - Variable: int rl_point
- The offset of the current cursor position in `rl_line_buffer' (the
- *point*).
-
- - Variable: int rl_end
- The number of characters present in `rl_line_buffer'. When
- `rl_point' is at the end of the line, `rl_point' and `rl_end' are
- equal.
-
- - Variable: int rl_mark
- The mark (saved position) in the current line. If set, the mark
- and point define a *region*.
-
- - Variable: int rl_done
- Setting this to a non-zero value causes Readline to return the
- current line immediately.
-
- - Variable: int rl_pending_input
- Setting this to a value makes it the next keystroke read. This is
- a way to stuff a single character into the input stream.
-
- - Variable: char * rl_prompt
- The prompt Readline uses. This is set from the argument to
- `readline ()', and should not be assigned to directly.
-
- - Variable: char * rl_terminal_name
- The terminal type, used for initialization.
-
- - Variable: char * rl_readline_name
- This variable is set to a unique name by each application using
- Readline. The value allows conditional parsing of the inputrc file
- (*note Conditional Init Constructs::.).
-
- - Variable: FILE * rl_instream
- The stdio stream from which Readline reads input.
-
- - Variable: FILE * rl_outstream
- The stdio stream to which Readline performs output.
-
- - Variable: Function * rl_startup_hook
- If non-zero, this is the address of a function to call just before
- `readline' prints the first prompt.

-
-
-File: readline.info, Node: Function Naming, Next: Keymaps, Up: Readline Convenience Functions
-
-Naming a Function
------------------
-
- The user can dynamically change the bindings of keys while using
-Readline. This is done by representing the function with a descriptive
-name. The user is able to type the descriptive name when referring to
-the function. Thus, in an init file, one might find
-
- Meta-Rubout: backward-kill-word
-
- This binds the keystroke Meta-Rubout to the function *descriptively*
-named `backward-kill-word'. You, as the programmer, should bind the
-functions you write to descriptive names as well. Readline provides a
-function for doing that:
-
- - Function: int rl_add_defun (char *name, Function *function, int key)
- Add NAME to the list of named functions. Make FUNCTION be the
- function that gets called. If KEY is not -1, then bind it to
- FUNCTION using `rl_bind_key ()'.
-
- Using this function alone is sufficient for most applications. It is
-the recommended way to add a few functions to the default functions that
-Readline has built in. If you need to do something other than adding a
-function to Readline, you may need to use the underlying functions
-described below.
-
-
-File: readline.info, Node: Keymaps, Next: Binding Keys, Prev: Function Naming, Up: Readline Convenience Functions
-
-Selecting a Keymap
-------------------
-
- Key bindings take place on a "keymap". The keymap is the
-association between the keys that the user types and the functions that
-get run. You can make your own keymaps, copy existing keymaps, and tell
-Readline which keymap to use.
-
- - Function: Keymap rl_make_bare_keymap ()
- Returns a new, empty keymap. The space for the keymap is
- allocated with `malloc ()'; you should `free ()' it when you are
- done.
-
- - Function: Keymap rl_copy_keymap (Keymap map)
- Return a new keymap which is a copy of MAP.
-
- - Function: Keymap rl_make_keymap ()
- Return a new keymap with the printing characters bound to
- rl_insert, the lowercase Meta characters bound to run their
- equivalents, and the Meta digits bound to produce numeric
- arguments.
-
- - Function: void rl_discard_keymap (Keymap keymap)
- Free the storage associated with KEYMAP.
-
- Readline has several internal keymaps. These functions allow you to
-change which keymap is active.
-
- - Function: Keymap rl_get_keymap ()
- Returns the currently active keymap.
-
- - Function: void rl_set_keymap (Keymap keymap)
- Makes KEYMAP the currently active keymap.
-
- - Function: Keymap rl_get_keymap_by_name (char *name)
- Return the keymap matching NAME. NAME is one which would be
- supplied in a `set keymap' inputrc line (*note Readline Init
- File::.).
-
-
-File: readline.info, Node: Binding Keys, Next: Associating Function Names and Bindings, Prev: Keymaps, Up: Readline Convenience Functions
-
-Binding Keys
-------------
-
- You associate keys with functions through the keymap. Readline has
-several internal keymaps: `emacs_standard_keymap', `emacs_meta_keymap',
-`emacs_ctlx_keymap', `vi_movement_keymap', and `vi_insertion_keymap'.
-`emacs_standard_keymap' is the default, and the examples in this manual
-assume that.
-
- These functions manage key bindings.
-
- - Function: int rl_bind_key (int key, Function *function)
- Binds KEY to FUNCTION in the currently active keymap. Returns
- non-zero in the case of an invalid KEY.
-
- - Function: int rl_bind_key_in_map (int key, Function *function,
- Keymap map)
- Bind KEY to FUNCTION in MAP. Returns non-zero in the case of an
- invalid KEY.
-
- - Function: int rl_unbind_key (int key)
- Bind KEY to the null function in the currently active keymap.
- Returns non-zero in case of error.
-
- - Function: int rl_unbind_key_in_map (int key, Keymap map)
- Bind KEY to the null function in MAP. Returns non-zero in case of
- error.
-
- - Function: int rl_generic_bind (int type, char *keyseq, char *data,
- Keymap map)
- Bind the key sequence represented by the string KEYSEQ to the
- arbitrary pointer DATA. TYPE says what kind of data is pointed to
- by DATA; this can be a function (`ISFUNC'), a macro (`ISMACR'), or
- a keymap (`ISKMAP'). This makes new keymaps as necessary. The
- initial keymap in which to do bindings is MAP.
-
- - Function: int rl_parse_and_bind (char *line)
- Parse LINE as if it had been read from the `inputrc' file and
- perform any key bindings and variable assignments found (*note
- Readline Init File::.).
-
-
-File: readline.info, Node: Associating Function Names and Bindings, Next: Allowing Undoing, Prev: Binding Keys, Up: Readline Convenience Functions
-
-Associating Function Names and Bindings
----------------------------------------
-
- These functions allow you to find out what keys invoke named
-functions and the functions invoked by a particular key sequence.
-
- - Function: Function * rl_named_function (char *name)
- Return the function with name NAME.
-
- - Function: Function * rl_function_of_keyseq (char *keyseq, Keymap
- map, int *type)
- Return the function invoked by KEYSEQ in keymap MAP. If MAP is
- NULL, the current keymap is used. If TYPE is not NULL, the type
- of the object is returned in it (one of `ISFUNC', `ISKMAP', or
- `ISMACR').
-
- - Function: char ** rl_invoking_keyseqs (Function *function)
- Return an array of strings representing the key sequences used to
- invoke FUNCTION in the current keymap.
-
- - Function: char ** rl_invoking_keyseqs_in_map (Function *function,
- Keymap map)
- Return an array of strings representing the key sequences used to
- invoke FUNCTION in the keymap MAP.

-
-Allowing Undoing
-----------------
-
- Supporting the undo command is a painless thing, and makes your
-functions much more useful. It is certainly easy to try something if
-you know you can undo it. I could use an undo function for the stock
-market.
-
- If your function simply inserts text once, or deletes text once, and
-uses `rl_insert_text ()' or `rl_delete_text ()' to do it, then undoing
-is already done for you automatically.
-
- If you do multiple insertions or multiple deletions, or any
-combination of these operations, you should group them together into
-one operation. This is done with `rl_begin_undo_group ()' and
-`rl_end_undo_group ()'.
-
- The types of events that can be undone are:
-
- enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
-
- Notice that `UNDO_DELETE' means to insert some text, and
-`UNDO_INSERT' means to delete some text. That is, the undo code tells
-undo what to undo, not how to undo it. `UNDO_BEGIN' and `UNDO_END' are
-tags added by `rl_begin_undo_group ()' and `rl_end_undo_group ()'.
-
- - Function: int rl_begin_undo_group ()
- Begins saving undo information in a group construct. The undo
- information usually comes from calls to `rl_insert_text ()' and
- `rl_delete_text ()', but could be the result of calls to
- `rl_add_undo ()'.
-
- - Function: int rl_end_undo_group ()
- Closes the current undo group started with `rl_begin_undo_group
- ()'. There should be one call to `rl_end_undo_group ()' for each
- call to `rl_begin_undo_group ()'.
-
- - Function: void rl_add_undo (enum undo_code what, int start, int end,
- char *text)
- Remember how to undo an event (according to WHAT). The affected
- text runs from START to END, and encompasses TEXT.
-
- - Function: void free_undo_list ()
- Free the existing undo list.
-
- - Function: int rl_do_undo ()
- Undo the first thing on the undo list. Returns `0' if there was
- nothing to undo, non-zero if something was undone.
-
- Finally, if you neither insert nor delete text, but directly modify
-the existing text (e.g., change its case), call `rl_modifying ()' once,
-just before you modify the text. You must supply the indices of the
-text range that you are going to modify.
-
- - Function: int rl_modifying (int start, int end)
- Tell Readline to save the text between START and END as a single
- undo unit. It is assumed that you will subsequently modify that
- text.
-
-
-File: readline.info, Node: Redisplay, Next: Modifying Text, Prev: Allowing Undoing, Up: Readline Convenience Functions
-
-Redisplay
----------
-
- - Function: int rl_redisplay ()
- Change what's displayed on the screen to reflect the current
- contents of `rl_line_buffer'.
-
- - Function: int rl_forced_update_display ()
- Force the line to be updated and redisplayed, whether or not
- Readline thinks the screen display is correct.
-
- - Function: int rl_on_new_line ()
- Tell the update routines that we have moved onto a new (empty)
- line, usually after ouputting a newline.
-
- - Function: int rl_reset_line_state ()
- Reset the display state to a clean state and redisplay the current
- line starting on a new line.
-
- - Function: int rl_message (va_alist)
- The arguments are a string as would be supplied to `printf'. The
- resulting string is displayed in the "echo area". The echo area
- is also used to display numeric arguments and search strings.
-
- - Function: int rl_clear_message ()
- Clear the message in the echo area.

-Custom Completers
-=================
-
- Typically, a program that reads commands from the user has a way of
-disambiguating commands and data. If your program is one of these, then
-it can provide completion for commands, data, or both. The following
-sections describe how your program and Readline cooperate to provide
-this service.
-
-* Menu:
-
-* How Completing Works:: The logic used to do completion.
-* Completion Functions:: Functions provided by Readline.
-* Completion Variables:: Variables which control completion.
-* A Short Completion Example:: An example of writing completer subroutines.

-
-How Completing Works
---------------------
-
- In order to complete some text, the full list of possible completions
-must be available. That is, it is not possible to accurately expand a
-partial word without knowing all of the possible words which make sense
-in that context. The Readline library provides the user interface to
-completion, and two of the most common completion functions: filename
-and username. For completing other types of text, you must write your
-own completion function. This section describes exactly what such
-functions must do, and provides an example.
-
- There are three major functions used to perform completion:
-
- 1. The user-interface function `rl_complete ()'. This function is
- called with the same arguments as other Readline functions
- intended for interactive use: COUNT and INVOKING_KEY. It
- isolates the word to be completed and calls `completion_matches
- ()' to generate a list of possible completions. It then either
- lists the possible completions, inserts the possible completions,
- or actually performs the completion, depending on which behavior
- is desired.
-
- 2. The internal function `completion_matches ()' uses your
- "generator" function to generate the list of possible matches, and
- then returns the array of these matches. You should place the
- address of your generator function in
- `rl_completion_entry_function'.
-
- 3. The generator function is called repeatedly from
- `completion_matches ()', returning a string each time. The
- arguments to the generator function are TEXT and STATE. TEXT is
- the partial word to be completed. STATE is zero the first time
- the function is called, allowing the generator to perform any
- necessary initialization, and a positive non-zero integer for each
- subsequent call. When the generator function returns `(char
- *)NULL' this signals `completion_matches ()' that there are no
- more possibilities left. Usually the generator function computes
- the list of possible completions when STATE is zero, and returns
- them one at a time on subsequent calls. Each string the generator
- function returns as a match must be allocated with `malloc()';
- Readline frees the strings when it has finished with them.
-
-
- - Function: int rl_complete (int ignore, int invoking_key)
- Complete the word at or before point. You have supplied the
- function that does the initial simple matching selection algorithm
- (see `completion_matches ()'). The default is to do filename
- completion.
-
- - Variable: Function * rl_completion_entry_function
- This is a pointer to the generator function for `completion_matches
- ()'. If the value of `rl_completion_entry_function' is `(Function
- *)NULL' then the default filename generator function,
- `filename_entry_function ()', is used.
-

-
-Completion Functions
---------------------
-
- Here is the complete list of callable completion functions present in
-Readline.
-
- - Function: int rl_complete_internal (int what_to_do)
- Complete the word at or before point. WHAT_TO_DO says what to do
- with the completion. A value of `?' means list the possible
- completions. `TAB' means do standard completion. `*' means
- insert all of the possible completions. `!' means to display all
- of the possible completions, if there is more than one, as well as
- performing partial completion.
-
- - Function: int rl_complete (int ignore, int invoking_key)
- Complete the word at or before point. You have supplied the
- function that does the initial simple matching selection algorithm
- (see `completion_matches ()' and `rl_completion_entry_function').
- The default is to do filename completion. This calls
- `rl_complete_internal ()' with an argument depending on
- INVOKING_KEY.
-
- - Function: int rl_possible_completions (int count, int invoking_key))
- List the possible completions. See description of `rl_complete
- ()'. This calls `rl_complete_internal ()' with an argument of `?'.
-
- - Function: int rl_insert_completions (int count, int invoking_key))
- Insert the list of possible completions into the line, deleting the
- partially-completed word. See description of `rl_complete ()'.
- This calls `rl_complete_internal ()' with an argument of `*'.
-
- - Function: char ** completion_matches (char *text, CPFunction
- *entry_func)
- Returns an array of `(char *)' which is a list of completions for
- TEXT. If there are no completions, returns `(char **)NULL'. The
- first entry in the returned array is the substitution for TEXT.
- The remaining entries are the possible completions. The array is
- terminated with a `NULL' pointer.
-
- ENTRY_FUNC is a function of two args, and returns a `(char *)'.
- The first argument is TEXT. The second is a state argument; it is
- zero on the first call, and non-zero on subsequent calls.
- eNTRY_FUNC returns a `NULL' pointer to the caller when there are
- no more matches.
-
- - Function: char * filename_completion_function (char *text, int state)
- A generator function for filename completion in the general case.
- Note that completion in Bash is a little different because of all
- the pathnames that must be followed when looking up completions
- for a command. The Bash source is a useful reference for writing
- custom completion functions.
-
- - Function: char * username_completion_function (char *text, int state)
- A completion generator for usernames. TEXT contains a partial
- username preceded by a random character (usually `~'). As with all
- completion generators, STATE is zero on the first call and non-zero
- for subsequent calls.
-
-
-File: readline.info, Node: Completion Variables, Next: A Short Completion Example, Prev: Completion Functions, Up: Custom Completers
-
-Completion Variables
---------------------
-
- - Variable: Function * rl_completion_entry_function
- A pointer to the generator function for `completion_matches ()'.
- `NULL' means to use `filename_entry_function ()', the default
- filename completer.
-
- - Variable: CPPFunction * rl_attempted_completion_function
- A pointer to an alternative function to create matches. The
- function is called with TEXT, START, and END. START and END are
- indices in `rl_line_buffer' saying what the boundaries of TEXT
- are. If this function exists and returns `NULL', or if this
- variable is set to `NULL', then `rl_complete ()' will call the
- value of `rl_completion_entry_function' to generate matches,
- otherwise the array of strings returned will be used.
-
- - Variable: int rl_completion_query_items
- Up to this many items will be displayed in response to a
- possible-completions call. After that, we ask the user if she is
- sure she wants to see them all. The default value is 100.
-
- - Variable: char * rl_basic_word_break_characters
- The basic list of characters that signal a break between words for
- the completer routine. The default value of this variable is the
- characters which break words for completion in Bash, i.e., `"
- \t\n\"\\'`@$><=;|&{("'.
-
- - Variable: char * rl_completer_word_break_characters
- The list of characters that signal a break between words for
- `rl_complete_internal ()'. The default list is the value of
- `rl_basic_word_break_characters'.
-
- - Variable: char * rl_special_prefixes
- The list of characters that are word break characters, but should
- be left in TEXT when it is passed to the completion function.
- Programs can use this to help determine what kind of completing to
- do. For instance, Bash sets this variable to "$@" so that it can
- complete shell variables and hostnames.
-
- - Variable: int rl_ignore_completion_duplicates
- If non-zero, then disallow duplicates in the matches. Default is
- 1.
-
- - Variable: int rl_filename_completion_desired
- Non-zero means that the results of the matches are to be treated as
- filenames. This is *always* zero on entry, and can only be changed
- within a completion entry generator function. If it is set to a
- non-zero value, directory names have a slash appended and Readline
- attempts to quote completed filenames if they contain any embedded
- word break characters.
-
- - Variable: int rl_filename_quoting_desired
- Non-zero means that the results of the matches are to be quoted
- using double quotes (or an application-specific quoting mechanism)
- if the completed filename contains any characters in
- `rl_completer_word_break_chars'. This is *always* non-zero on
- entry, and can only be changed within a completion entry generator
- function.
-
- - Variable: Function * rl_ignore_some_completions_function
- This function, if defined, is called by the completer when real
- filename completion is done, after all the matching names have
- been generated. It is passed a `NULL' terminated array of matches.
- The first element (`matches[0]') is the maximal substring common
- to all matches. This function can re-arrange the list of matches
- as required, but each element deleted from the array must be freed.
-
- - Variable: char * rl_completer_quote_characters
- List of characters which can be used to quote a substring of the
- line. Completion occurs on the entire substring, and within the
- substring `rl_completer_word_break_characters' are treated as any
- other character, unless they also appear within this list.

-Overview
-********
-
- A "regular expression" (or "regexp", or "pattern") is a text string
-that describes some (mathematical) set of strings. A regexp R
-"matches" a string S if S is in the set of strings described by R.
-
- Using the Regex library, you can:
-
- * see if a string matches a specified pattern as a whole, and
-
- * search within a string for a substring matching a specified
- pattern.
-
- Some regular expressions match only one string, i.e., the set they
-describe has only one member. For example, the regular expression
-`foo' matches the string `foo' and no others. Other regular
-expressions match more than one string, i.e., the set they describe has
-more than one member. For example, the regular expression `f*' matches
-the set of strings made up of any number (including zero) of `f's. As
-you can see, some characters in regular expressions match themselves
-(such as `f') and some don't (such as `*'); the ones that don't match
-themselves instead let you specify patterns that describe many
-different strings.
-
- To either match or search for a regular expression with the Regex
-library functions, you must first compile it with a Regex pattern
-compiling function. A "compiled pattern" is a regular expression
-converted to the internal format used by the library functions. Once
-you've compiled a pattern, you can use it for matching or searching any
-number of times.
-
- The Regex library consists of two source files: `regex.h' and
-`regex.c'. Regex provides three groups of functions with which you can
-operate on regular expressions. One group--the GNU group--is more
-powerful but not completely compatible with the other two, namely the
-POSIX and Berkeley UNIX groups; its interface was designed specifically
-for GNU. The other groups have the same interfaces as do the regular
-expression functions in POSIX and Berkeley UNIX.
-
- We wrote this chapter with programmers in mind, not users of
-programs--such as Emacs--that use Regex. We describe the Regex library
-in its entirety, not how to write regular expressions that a particular
-program understands.

-Regular Expression Syntax
-*************************
-
- "Characters" are things you can type. "Operators" are things in a
-regular expression that match one or more characters. You compose
-regular expressions from operators, which in turn you specify using one
-or more characters.
-
- Most characters represent what we call the match-self operator, i.e.,
-they match themselves; we call these characters "ordinary". Other
-characters represent either all or parts of fancier operators; e.g.,
-`.' represents what we call the match-any-character operator (which, no
-surprise, matches (almost) any character); we call these characters
-"special". Two different things determine what characters represent
-what operators:
-
- 1. the regular expression syntax your program has told the Regex
- library to recognize, and
-
- 2. the context of the character in the regular expression.
-
- In the following sections, we describe these things in more detail.

-
-Syntax Bits
-===========
-
- In any particular syntax for regular expressions, some characters are
-always special, others are sometimes special, and others are never
-special. The particular syntax that Regex recognizes for a given
-regular expression depends on the value in the `syntax' field of the
-pattern buffer of that regular expression.
-
- You get a pattern buffer by compiling a regular expression. *Note
-GNU Pattern Buffers::, and *Note POSIX Pattern Buffers::, for more
-information on pattern buffers. *Note GNU Regular Expression
-Compiling::, *Note POSIX Regular Expression Compiling::, and *Note BSD
-Regular Expression Compiling::, for more information on compiling.
-
- Regex considers the value of the `syntax' field to be a collection of
-bits; we refer to these bits as "syntax bits". In most cases, they
-affect what characters represent what operators. We describe the
-meanings of the operators to which we refer in *Note Common Operators::,
-*Note GNU Operators::, and *Note GNU Emacs Operators::.
-
- For reference, here is the complete list of syntax bits, in
-alphabetical order:
-
-`RE_BACKSLASH_ESCAPE_IN_LISTS'
- If this bit is set, then `\' inside a list (*note List Operators::.
- quotes (makes ordinary, if it's special) the following character;
- if this bit isn't set, then `\' is an ordinary character inside
- lists. (*Note The Backslash Character::, for what `\' does
- outside of lists.)
-
-`RE_BK_PLUS_QM'
- If this bit is set, then `\+' represents the match-one-or-more
- operator and `\?' represents the match-zero-or-more operator; if
- this bit isn't set, then `+' represents the match-one-or-more
- operator and `?' represents the match-zero-or-one operator. This
- bit is irrelevant if `RE_LIMITED_OPS' is set.
-
-`RE_CHAR_CLASSES'
- If this bit is set, then you can use character classes in lists;
- if this bit isn't set, then you can't.
-
-`RE_CONTEXT_INDEP_ANCHORS'
- If this bit is set, then `^' and `$' are special anywhere outside
- a list; if this bit isn't set, then these characters are special
- only in certain contexts. *Note Match-beginning-of-line
- Operator::, and *Note Match-end-of-line Operator::.
-
-`RE_CONTEXT_INDEP_OPS'
- If this bit is set, then certain characters are special anywhere
- outside a list; if this bit isn't set, then those characters are
- special only in some contexts and are ordinary elsewhere.
- Specifically, if this bit isn't set then `*', and (if the syntax
- bit `RE_LIMITED_OPS' isn't set) `+' and `?' (or `\+' and `\?',
- depending on the syntax bit `RE_BK_PLUS_QM') represent repetition
- operators only if they're not first in a regular expression or
- just after an open-group or alternation operator. The same holds
- for `{' (or `\{', depending on the syntax bit `RE_NO_BK_BRACES') if
- it is the beginning of a valid interval and the syntax bit
- `RE_INTERVALS' is set.
-
-`RE_CONTEXT_INVALID_OPS'
- If this bit is set, then repetition and alternation operators
- can't be in certain positions within a regular expression.
- Specifically, the regular expression is invalid if it has:
-
- * a repetition operator first in the regular expression or just
- after a match-beginning-of-line, open-group, or alternation
- operator; or
-
- * an alternation operator first or last in the regular
- expression, just before a match-end-of-line operator, or just
- after an alternation or open-group operator.
-
- If this bit isn't set, then you can put the characters
- representing the repetition and alternation characters anywhere in
- a regular expression. Whether or not they will in fact be
- operators in certain positions depends on other syntax bits.
-
-`RE_DOT_NEWLINE'
- If this bit is set, then the match-any-character operator matches
- a newline; if this bit isn't set, then it doesn't.
-
-`RE_DOT_NOT_NULL'
- If this bit is set, then the match-any-character operator doesn't
- match a null character; if this bit isn't set, then it does.
-
-`RE_INTERVALS'
- If this bit is set, then Regex recognizes interval operators; if
- this bit isn't set, then it doesn't.
-
-`RE_LIMITED_OPS'
- If this bit is set, then Regex doesn't recognize the
- match-one-or-more, match-zero-or-one or alternation operators; if
- this bit isn't set, then it does.
-
-`RE_NEWLINE_ALT'
- If this bit is set, then newline represents the alternation
- operator; if this bit isn't set, then newline is ordinary.
-
-`RE_NO_BK_BRACES'
- If this bit is set, then `{' represents the open-interval operator
- and `}' represents the close-interval operator; if this bit isn't
- set, then `\{' represents the open-interval operator and `\}'
- represents the close-interval operator. This bit is relevant only
- if `RE_INTERVALS' is set.
-
-`RE_NO_BK_PARENS'
- If this bit is set, then `(' represents the open-group operator and
- `)' represents the close-group operator; if this bit isn't set,
- then `\(' represents the open-group operator and `\)' represents
- the close-group operator.
-
-`RE_NO_BK_REFS'
- If this bit is set, then Regex doesn't recognize `\'DIGIT as the
- back reference operator; if this bit isn't set, then it does.
-
-`RE_NO_BK_VBAR'
- If this bit is set, then `|' represents the alternation operator;
- if this bit isn't set, then `\|' represents the alternation
- operator. This bit is irrelevant if `RE_LIMITED_OPS' is set.
-
-`RE_NO_EMPTY_RANGES'
- If this bit is set, then a regular expression with a range whose
- ending point collates lower than its starting point is invalid; if
- this bit isn't set, then Regex considers such a range to be empty.
-
-`RE_UNMATCHED_RIGHT_PAREN_ORD'
- If this bit is set and the regular expression has no matching
- open-group operator, then Regex considers what would otherwise be
- a close-group operator (based on how `RE_NO_BK_PARENS' is set) to
- match `)'.

-Predefined Syntaxes
-===================
-
- If you're programming with Regex, you can set a pattern buffer's
-(*note GNU Pattern Buffers::., and *Note POSIX Pattern Buffers::)
-`syntax' field either to an arbitrary combination of syntax bits (*note
-Syntax Bits::.) or else to the configurations defined by Regex. These
-configurations define the syntaxes used by certain programs--GNU Emacs,
-POSIX Awk, traditional Awk, Grep, Egrep--in addition to syntaxes for
-POSIX basic and extended regular expressions.
-
- The predefined syntaxes-taken directly from `regex.h'--are:

-Collating Elements vs. Characters
-=================================
-
- POSIX generalizes the notion of a character to that of a collating
-element. It defines a "collating element" to be "a sequence of one or
-more bytes defined in the current collating sequence as a unit of
-collation."
-
- This generalizes the notion of a character in two ways. First, a
-single character can map into two or more collating elements. For
-example, the German "es-zet" collates as the collating element `s'
-followed by another collating element `s'. Second, two or more
-characters can map into one collating element. For example, the
-Spanish `ll' collates after `l' and before `m'.
-
- Since POSIX's "collating element" preserves the essential idea of a
-"character," we use the latter, more familiar, term in this document.
-
-
-File: regex.info, Node: The Backslash Character, Prev: Collating Elements vs. Characters, Up: Regular Expression Syntax
-
-The Backslash Character
-=======================
-
- The `\' character has one of four different meanings, depending on
-the context in which you use it and what syntax bits are set (*note
-Syntax Bits::.). It can: 1) stand for itself, 2) quote the next
-character, 3) introduce an operator, or 4) do nothing.
-
- 1. It stands for itself inside a list (*note List Operators::.) if
- the syntax bit `RE_BACKSLASH_ESCAPE_IN_LISTS' is not set. For
- example, `[\]' would match `\'.
-
- 2. It quotes (makes ordinary, if it's special) the next character
- when you use it either:
-
- * outside a list,(1) or
-
- * inside a list and the syntax bit
- `RE_BACKSLASH_ESCAPE_IN_LISTS' is set.
-
- 3. It introduces an operator when followed by certain ordinary
- characters--sometimes only when certain syntax bits are set. See
- the cases `RE_BK_PLUS_QM', `RE_NO_BK_BRACES', `RE_NO_BK_VAR',
- `RE_NO_BK_PARENS', `RE_NO_BK_REF' in *Note Syntax Bits::. Also:
-
- * `\b' represents the match-word-boundary operator (*note
- Match-word-boundary Operator::.).
-
- * `\B' represents the match-within-word operator (*note
- Match-within-word Operator::.).
-
- * `\<' represents the match-beginning-of-word operator
- (*note Match-beginning-of-word Operator::.).
-
- * `\>' represents the match-end-of-word operator (*note
- Match-end-of-word Operator::.).
-
- * `\w' represents the match-word-constituent operator (*note
- Match-word-constituent Operator::.).
-
- * `\W' represents the match-non-word-constituent operator
- (*note Match-non-word-constituent Operator::.).
-
- * `\`' represents the match-beginning-of-buffer operator and
- `\'' represents the match-end-of-buffer operator (*note
- Buffer Operators::.).
-
- * If Regex was compiled with the C preprocessor symbol `emacs'
- defined, then `\sCLASS' represents the match-syntactic-class
- operator and `\SCLASS' represents the
- match-not-syntactic-class operator (*note Syntactic Class
- Operators::.).
-
- 4. In all other cases, Regex ignores `\'. For example, `\n' matches
- `n'.
-
-
- ---------- Footnotes ----------
-
- (1) Sometimes you don't have to explicitly quote special characters
-to make them ordinary. For instance, most characters lose any special
-meaning inside a list (*note List Operators::.). In addition, if the
-syntax bits `RE_CONTEXT_INVALID_OPS' and `RE_CONTEXT_INDEP_OPS' aren't
-set, then (for historical reasons) the matcher considers special
-characters ordinary if they are in contexts where the operations they
-represent make no sense; for example, then the match-zero-or-more
-operator (represented by `*') matches itself in the regular expression
-`*foo' because there is no preceding expression on which it can
-operate. It is poor practice, however, to depend on this behavior; if
-you want a special character to be ordinary outside a list, it's better
-to always quote it, regardless.

-Common Operators
-****************
-
- You compose regular expressions from operators. In the following
-sections, we describe the regular expression operators specified by
-POSIX; GNU also uses these. Most operators have more than one
-representation as characters. *Note Regular Expression Syntax::, for
-what characters represent what operators under what circumstances.
-
- For most operators that can be represented in two ways, one
-representation is a single character and the other is that character
-preceded by `\'. For example, either `(' or `\(' represents the
-open-group operator. Which one does depends on the setting of a syntax
-bit, in this case `RE_NO_BK_PARENS'. Why is this so? Historical
-reasons dictate some of the varying representations, while POSIX
-dictates others.
-
- Finally, almost all characters lose any special meaning inside a list
-(*note List Operators::.).

-The Match-self Operator (ORDINARY CHARACTER)
-============================================
-
- This operator matches the character itself. All ordinary characters
-(*note Regular Expression Syntax::.) represent this operator. For
-example, `f' is always an ordinary character, so the regular expression
-`f' matches only the string `f'. In particular, it does *not* match
-the string `ff'.
-
-

-
-The Match-any-character Operator (`.')
-======================================
-
- This operator matches any single printing or nonprinting character
-except it won't match a:
-
-newline
- if the syntax bit `RE_DOT_NEWLINE' isn't set.
-
-null
- if the syntax bit `RE_DOT_NOT_NULL' is set.
-
- The `.' (period) character represents this operator. For example,
-`a.b' matches any three-character string beginning with `a' and ending
-with `b'.
-
-
-File: regex.info, Node: Concatenation Operator, Next: Repetition Operators, Prev: Match-any-character Operator, Up: Common Operators
-
-The Concatenation Operator
-==========================
-
- This operator concatenates two regular expressions A and B. No
-character represents this operator; you simply put B after A. The
-result is a regular expression that will match a string if A matches
-its first part and B matches the rest. For example, `xy' (two
-match-self operators) matches `xy'.
-
-
-File: regex.info, Node: Repetition Operators, Next: Alternation Operator, Prev: Concatenation Operator, Up: Common Operators
-
-Repetition Operators
-====================
-
- Repetition operators repeat the preceding regular expression a
-specified number of times.

-
-* Match-zero-or-more Operator:: *
-* Match-one-or-more Operator:: +

-* Interval Operators:: {}
-
-
-File: regex.info, Node: Match-zero-or-more Operator, Next: Match-one-or-more Operator, Up: Repetition Operators
-
-The Match-zero-or-more Operator (`*')
--------------------------------------
-
- This operator repeats the smallest possible preceding regular
-expression as many times as necessary (including zero) to match the
-pattern. `*' represents this operator. For example, `o*' matches any
-string made up of zero or more `o's. Since this operator operates on
-the smallest preceding regular expression, `fo*' has a repeating `o',
-not a repeating `fo'. So, `fo*' matches `f', `fo', `foo', and so on.
-
- Since the match-zero-or-more operator is a suffix operator, it may be
-useless as such when no regular expression precedes it. This is the
-case when it:
-
- * is first in a regular expression, or
-
- * follows a match-beginning-of-line, open-group, or alternation
- operator.
-
-Three different things can happen in these cases:
-
- 1. If the syntax bit `RE_CONTEXT_INVALID_OPS' is set, then the
- regular expression is invalid.
-
- 2. If `RE_CONTEXT_INVALID_OPS' isn't set, but `RE_CONTEXT_INDEP_OPS'
- is, then `*' represents the match-zero-or-more operator (which
- then operates on the empty string).
-
- 3. Otherwise, `*' is ordinary.
-
-
- The matcher processes a match-zero-or-more operator by first matching
-as many repetitions of the smallest preceding regular expression as it
-can. Then it continues to match the rest of the pattern.
-
- If it can't match the rest of the pattern, it backtracks (as many
-times as necessary), each time discarding one of the matches until it
-can either match the entire pattern or be certain that it cannot get a
-match. For example, when matching `ca*ar' against `caaar', the matcher
-first matches all three `a's of the string with the `a*' of the regular
-expression. However, it cannot then match the final `ar' of the
-regular expression against the final `r' of the string. So it
-backtracks, discarding the match of the last `a' in the string. It can
-then match the remaining `ar'.

-
-The Match-one-or-more Operator (`+' or `\+')
---------------------------------------------
-
- If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
-recognize this operator. Otherwise, if the syntax bit `RE_BK_PLUS_QM'
-isn't set, then `+' represents this operator; if it is, then `\+' does.
-
- This operator is similar to the match-zero-or-more operator except
-that it repeats the preceding regular expression at least once; *note
-Match-zero-or-more Operator::., for what it operates on, how some
-syntax bits affect it, and how Regex backtracks to match it.
-
- For example, supposing that `+' represents the match-one-or-more
-operator; then `ca+r' matches, e.g., `car' and `caaaar', but not `cr'.

-
-The Match-zero-or-one Operator (`?' or `\?')
---------------------------------------------
-
- If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
-recognize this operator. Otherwise, if the syntax bit `RE_BK_PLUS_QM'
-isn't set, then `?' represents this operator; if it is, then `\?' does.
-
- This operator is similar to the match-zero-or-more operator except
-that it repeats the preceding regular expression once or not at all;
-*note Match-zero-or-more Operator::., to see what it operates on, how
-some syntax bits affect it, and how Regex backtracks to match it.
-
- For example, supposing that `?' represents the match-zero-or-one
-operator; then `ca?r' matches both `car' and `cr', but nothing else.
-
-
-File: regex.info, Node: Interval Operators, Prev: Match-zero-or-one Operator, Up: Repetition Operators
-
-Interval Operators (`{' ... `}' or `\{' ... `\}')
--------------------------------------------------
-
- If the syntax bit `RE_INTERVALS' is set, then Regex recognizes
-"interval expressions". They repeat the smallest possible preceding
-regular expression a specified number of times.
-
- If the syntax bit `RE_NO_BK_BRACES' is set, `{' represents the
-"open-interval operator" and `}' represents the "close-interval
-operator" ; otherwise, `\{' and `\}' do.
-
- Specifically, supposing that `{' and `}' represent the open-interval
-and close-interval operators; then:
-
-`{COUNT}'
- matches exactly COUNT occurrences of the preceding regular
- expression.
-
-`{MIN,}'
- matches MIN or more occurrences of the preceding regular
- expression.
-
-`{MIN, MAX}'
- matches at least MIN but no more than MAX occurrences of the
- preceding regular expression.
-
- The interval expression (but not necessarily the regular expression
-that contains it) is invalid if:
-
- * MIN is greater than MAX, or
-
- * any of COUNT, MIN, or MAX are outside the range zero to
- `RE_DUP_MAX' (which symbol `regex.h' defines).
-
- If the interval expression is invalid and the syntax bit
-`RE_NO_BK_BRACES' is set, then Regex considers all the characters in
-the would-be interval to be ordinary. If that bit isn't set, then the
-regular expression is invalid.
-
- If the interval expression is valid but there is no preceding regular
-expression on which to operate, then if the syntax bit
-`RE_CONTEXT_INVALID_OPS' is set, the regular expression is invalid. If
-that bit isn't set, then Regex considers all the characters--other than
-backslashes, which it ignores--in the would-be interval to be ordinary.
-
-
-File: regex.info, Node: Alternation Operator, Next: List Operators, Prev: Repetition Operators, Up: Common Operators
-
-The Alternation Operator (`|' or `\|')
-======================================
-
- If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
-recognize this operator. Otherwise, if the syntax bit `RE_NO_BK_VBAR'
-is set, then `|' represents this operator; otherwise, `\|' does.
-
- Alternatives match one of a choice of regular expressions: if you put
-the character(s) representing the alternation operator between any two
-regular expressions A and B, the result matches the union of the
-strings that A and B match. For example, supposing that `|' is the
-alternation operator, then `foo|bar|quux' would match any of `foo',
-`bar' or `quux'.
-
- The alternation operator operates on the *largest* possible
-surrounding regular expressions. (Put another way, it has the lowest
-precedence of any regular expression operator.) Thus, the only way you
-can delimit its arguments is to use grouping. For example, if `(' and
-`)' are the open and close-group operators, then `fo(o|b)ar' would
-match either `fooar' or `fobar'. (`foo|bar' would match `foo' or
-`bar'.)
-
- The matcher usually tries all combinations of alternatives so as to
-match the longest possible string. For example, when matching
-`(fooq|foo)*(qbarquux|bar)' against `fooqbarquux', it cannot take, say,
-the first ("depth-first") combination it could match, since then it
-would be content to match just `fooqbar'.
-
-
-File: regex.info, Node: List Operators, Next: Grouping Operators, Prev: Alternation Operator, Up: Common Operators
-
-List Operators (`[' ... `]' and `[^' ... `]')
-=============================================
-
- "Lists", also called "bracket expressions", are a set of one or more
-items. An "item" is a character, a character class expression, or a
-range expression. The syntax bits affect which kinds of items you can
-put in a list. We explain the last two items in subsections below.
-Empty lists are invalid.
-
- A "matching list" matches a single character represented by one of
-the list items. You form a matching list by enclosing one or more items
-within an "open-matching-list operator" (represented by `[') and a
-"close-list operator" (represented by `]').
-
- For example, `[ab]' matches either `a' or `b'. `[ad]*' matches the
-empty string and any string composed of just `a's and `d's in any
-order. Regex considers invalid a regular expression with a `[' but no
-matching `]'.
-
- "Nonmatching lists" are similar to matching lists except that they
-match a single character *not* represented by one of the list items.
-You use an "open-nonmatching-list operator" (represented by `[^'(1))
-instead of an open-matching-list operator to start a nonmatching list.
-
- For example, `[^ab]' matches any character except `a' or `b'.
-
- If the `posix_newline' field in the pattern buffer (*note GNU Pattern
-Buffers::. is set, then nonmatching lists do not match a newline.
-
- Most characters lose any special meaning inside a list. The special
-characters inside a list follow.
-
-`]'
- ends the list if it's not the first list item. So, if you want to
- make the `]' character a list item, you must put it first.
-
-`\'
- quotes the next character if the syntax bit
- `RE_BACKSLASH_ESCAPE_IN_LISTS' is set.
-
-`[:'
- represents the open-character-class operator (*note Character
- Class Operators::.) if the syntax bit `RE_CHAR_CLASSES' is set and
- what follows is a valid character class expression.
-
-`:]'
- represents the close-character-class operator if the syntax bit
- `RE_CHAR_CLASSES' is set and what precedes it is an
- open-character-class operator followed by a valid character class
- name.
-
-`-'
- represents the range operator (*note Range Operator::.) if it's
- not first or last in a list or the ending point of a range.
-
-All other characters are ordinary. For example, `[.*]' matches `.' and
-`*'.
-
-* Menu:
-
-* Character Class Operators:: [:class:]
-* Range Operator:: start-end
-
- ---------- Footnotes ----------
-
- (1) Regex therefore doesn't consider the `^' to be the first
-character in the list. If you put a `^' character first in (what you
-think is) a matching list, you'll turn it into a nonmatching list.
-
-
-File: regex.info, Node: Character Class Operators, Next: Range Operator, Up: List Operators
-
-Character Class Operators (`[:' ... `:]')
------------------------------------------
-
- If the syntax bit `RE_CHARACTER_CLASSES' is set, then Regex
-recognizes character class expressions inside lists. A "character
-class expression" matches one character from a given class. You form a
-character class expression by putting a character class name between an
-"open-character-class operator" (represented by `[:') and a
-"close-character-class operator" (represented by `:]'). The character
-class names and their meanings are:
-
-`alnum'
- letters and digits
-
-`alpha'
- letters
-
-`blank'
- system-dependent; for GNU, a space or tab
-
-`cntrl'
- control characters (in the ASCII encoding, code 0177 and codes
- less than 040)
-
-`digit'
- digits
-
-`graph'
- same as `print' except omits space
-
-`lower'
- lowercase letters
-
-`print'
- printable characters (in the ASCII encoding, space tilde--codes
- 040 through 0176)
-
-`punct'
- neither control nor alphanumeric characters
-
-`space'
- space, carriage return, newline, vertical tab, and form feed
-
-`upper'
- uppercase letters
-
-`xdigit'
- hexadecimal digits: `0'-`9', `a'-`f', `A'-`F'
-
-These correspond to the definitions in the C library's `<ctype.h>'
-facility. For example, `[:alpha:]' corresponds to the standard
-facility `isalpha'. Regex recognizes character class expressions only
-inside of lists; so `[[:alpha:]]' matches any letter, but `[:alpha:]'
-outside of a bracket expression and not followed by a repetition
-operator matches just itself.
-
-
-File: regex.info, Node: Range Operator, Prev: Character Class Operators, Up: List Operators
-
-The Range Operator (`-')
-------------------------
-
- Regex recognizes "range expressions" inside a list. They represent
-those characters that fall between two elements in the current
-collating sequence. You form a range expression by putting a "range
-operator" between two characters.(1) `-' represents the range operator.
-For example, `a-f' within a list represents all the characters from `a'
-through `f' inclusively.
-
- If the syntax bit `RE_NO_EMPTY_RANGES' is set, then if the range's
-ending point collates less than its starting point, the range (and the
-regular expression containing it) is invalid. For example, the regular
-expression `[z-a]' would be invalid. If this bit isn't set, then Regex
-considers such a range to be empty.
-
- Since `-' represents the range operator, if you want to make a `-'
-character itself a list item, you must do one of the following:
-
- * Put the `-' either first or last in the list.
-
- * Include a range whose starting point collates strictly lower than
- `-' and whose ending point collates equal or higher. Unless a
- range is the first item in a list, a `-' can't be its starting
- point, but *can* be its ending point. That is because Regex
- considers `-' to be the range operator unless it is preceded by
- another `-'. For example, in the ASCII encoding, `)', `*', `+',
- `,', `-', `.', and `/' are contiguous characters in the collating
- sequence. You might think that `[)-+--/]' has two ranges: `)-+'
- and `--/'. Rather, it has the ranges `)-+' and `+--', plus the
- character `/', so it matches, e.g., `,', not `.'.
-
- * Put a range whose starting point is `-' first in the list.
-
- For example, `[-a-z]' matches a lowercase letter or a hyphen (in
-English, in ASCII).
-
- ---------- Footnotes ----------
-
- (1) You can't use a character class for the starting or ending point
-of a range, since a character class is not a single character.

-
-Grouping Operators (`(' ... `)' or `\(' ... `\)')
-=================================================
-
- A "group", also known as a "subexpression", consists of an
-"open-group operator", any number of other operators, and a
-"close-group operator". Regex treats this sequence as a unit, just as
-mathematics and programming languages treat a parenthesized expression
-as a unit.
-
- Therefore, using "groups", you can:
-
- * delimit the argument(s) to an alternation operator (*note
- Alternation Operator::.) or a repetition operator (*note
- Repetition Operators::.).
-
- * keep track of the indices of the substring that matched a given
- group. *Note Using Registers::, for a precise explanation. This
- lets you:
-
- * use the back-reference operator (*note Back-reference
- Operator::.).
-
- * use registers (*note Using Registers::.).
-
- If the syntax bit `RE_NO_BK_PARENS' is set, then `(' represents the
-open-group operator and `)' represents the close-group operator;
-otherwise, `\(' and `\)' do.
-
- If the syntax bit `RE_UNMATCHED_RIGHT_PAREN_ORD' is set and a
-close-group operator has no matching open-group operator, then Regex
-considers it to match `)'.
-
-
-File: regex.info, Node: Back-reference Operator, Next: Anchoring Operators, Prev: Grouping Operators, Up: Common Operators
-
-The Back-reference Operator ("\"DIGIT)
-======================================
-
- If the syntax bit `RE_NO_BK_REF' isn't set, then Regex recognizes
-back references. A back reference matches a specified preceding group.
-The back reference operator is represented by `\DIGIT' anywhere after
-the end of a regular expression's DIGIT-th group (*note Grouping
-Operators::.).
-
- DIGIT must be between `1' and `9'. The matcher assigns numbers 1
-through 9 to the first nine groups it encounters. By using one of `\1'
-through `\9' after the corresponding group's close-group operator, you
-can match a substring identical to the one that the group does.
-
- Back references match according to the following (in all examples
-below, `(' represents the open-group, `)' the close-group, `{' the
-open-interval and `}' the close-interval operator):
-
- * If the group matches a substring, the back reference matches an
- identical substring. For example, `(a)\1' matches `aa' and
- `(bana)na\1bo\1' matches `bananabanabobana'. Likewise, `(.*)\1'
- matches any (newline-free if the syntax bit `RE_DOT_NEWLINE' isn't
- set) string that is composed of two identical halves; the `(.*)'
- matches the first half and the `\1' matches the second half.
-
- * If the group matches more than once (as it might if followed by,
- e.g., a repetition operator), then the back reference matches the
- substring the group *last* matched. For example, `((a*)b)*\1\2'
- matches `aabababa'; first group 1 (the outer one) matches `aab'
- and group 2 (the inner one) matches `aa'. Then group 1 matches
- `ab' and group 2 matches `a'. So, `\1' matches `ab' and `\2'
- matches `a'.
-
- * If the group doesn't participate in a match, i.e., it is part of an
- alternative not taken or a repetition operator allows zero
- repetitions of it, then the back reference makes the whole match
- fail. For example, `(one()|two())-and-(three\2|four\3)' matches
- `one-and-three' and `two-and-four', but not `one-and-four' or
- `two-and-three'. For example, if the pattern matches `one-and-',
- then its group 2 matches the empty string and its group 3 doesn't
- participate in the match. So, if it then matches `four', then
- when it tries to back reference group 3--which it will attempt to
- do because `\3' follows the `four'--the match will fail because
- group 3 didn't participate in the match.
-
- You can use a back reference as an argument to a repetition operator.
-For example, `(a(b))\2*' matches `a' followed by two or more `b's.
-Similarly, `(a(b))\2{3}' matches `abbbb'.
-
- If there is no preceding DIGIT-th subexpression, the regular
-expression is invalid.

-Anchoring Operators
-===================
-
- These operators can constrain a pattern to match only at the
-beginning or end of the entire string or at the beginning or end of a
-line.

-* Match-end-of-line Operator:: $

-
-File: regex.info, Node: Match-beginning-of-line Operator, Next: Match-end-of-line Operator, Up: Anchoring Operators
-
-The Match-beginning-of-line Operator (`^')
-------------------------------------------
-
- This operator can match the empty string either at the beginning of
-the string or after a newline character. Thus, it is said to "anchor"
-the pattern to the beginning of a line.
-
- In the cases following, `^' represents this operator. (Otherwise,
-`^' is ordinary.)
-
- * It (the `^') is first in the pattern, as in `^foo'.
-
- * The syntax bit `RE_CONTEXT_INDEP_ANCHORS' is set, and it is outside
- a bracket expression.
-
- * It follows an open-group or alternation operator, as in `a\(^b\)'
- and `a\|^b'. *Note Grouping Operators::, and *Note Alternation
- Operator::.
-
- These rules imply that some valid patterns containing `^' cannot be
-matched; for example, `foo^bar' if `RE_CONTEXT_INDEP_ANCHORS' is set.
-
- If the `not_bol' field is set in the pattern buffer (*note GNU
-Pattern Buffers::.), then `^' fails to match at the beginning of the
-string. *Note POSIX Matching::, for when you might find this useful.
-
- If the `newline_anchor' field is set in the pattern buffer, then `^'
-fails to match after a newline. This is useful when you do not regard
-the string to be matched as broken into lines.
-
-
-File: regex.info, Node: Match-end-of-line Operator, Prev: Match-beginning-of-line Operator, Up: Anchoring Operators
-
-The Match-end-of-line Operator (`$')
-------------------------------------
-
- This operator can match the empty string either at the end of the
-string or before a newline character in the string. Thus, it is said
-to "anchor" the pattern to the end of a line.
-
- It is always represented by `$'. For example, `foo$' usually
-matches, e.g., `foo' and, e.g., the first three characters of
-`foo\nbar'.
-
- Its interaction with the syntax bits and pattern buffer fields is
-exactly the dual of `^''s; see the previous section. (That is,
-"beginning" becomes "end", "next" becomes "previous", and "after"
-becomes "before".)

-
-Non-Emacs Syntax Tables
------------------------
-
- A "syntax table" is an array indexed by the characters in your
-character set. In the ASCII encoding, therefore, a syntax table has
-256 elements. Regex always uses a `char *' variable `re_syntax_table'
-as its syntax table. In some cases, it initializes this variable and
-in others it expects you to initialize it.
-
- * If Regex is compiled with the preprocessor symbols `emacs' and
- `SYNTAX_TABLE' both undefined, then Regex allocates
- `re_syntax_table' and initializes an element I either to `Sword'
- (which it defines) if I is a letter, number, or `_', or to zero if
- it's not.
-
- * If Regex is compiled with `emacs' undefined but `SYNTAX_TABLE'
- defined, then Regex expects you to define a `char *' variable
- `re_syntax_table' to be a valid syntax table.
-
- * *Note Emacs Syntax Tables::, for what happens when Regex is
- compiled with the preprocessor symbol `emacs' defined.

-256 elements.
-
- If Regex is compiled with the preprocessor symbol `emacs' defined,
-then Regex expects you to define and initialize the variable
-`re_syntax_table' to be an Emacs syntax table. Emacs' syntax tables

-What Gets Matched?
-******************
-
- Regex usually matches strings according to the "leftmost longest"
-rule; that is, it chooses the longest of the leftmost matches. This
-does not mean that for a regular expression containing subexpressions
-that it simply chooses the longest match for each subexpression, left to
-right; the overall match must also be the longest possible one.
-
- For example, `(ac*)(c*d[ac]*)\1' matches `acdacaaa', not `acdac', as
-it would if it were to choose the longest match for the first
-subexpression.

-GNU Pattern Buffers
--------------------
-
- To compile, match, or search for a given regular expression, you must
-supply a pattern buffer. A "pattern buffer" holds one compiled regular
-expression.(1)
-
- You can have several different pattern buffers simultaneously, each
-holding a compiled pattern for a different regular expression.
-
- `regex.h' defines the pattern buffer `struct' as follows:

-
-GNU Regular Expression Compiling
---------------------------------
-
- In GNU, you can both match and search for a given regular expression.
-To do either, you must first compile it in a pattern buffer (*note GNU
-Pattern Buffers::.).
-
- Regular expressions match according to the syntax with which they were
-compiled; with GNU, you indicate what syntax you want by setting the
-variable `re_syntax_options' (declared in `regex.h' and defined in
-`regex.c') before calling the compiling function, `re_compile_pattern'
-(see below). *Note Syntax Bits::, and *Note Predefined Syntaxes::.
-
- You can change the value of `re_syntax_options' at any time.
-Usually, however, you set its value once and then never change it.
-
- `re_compile_pattern' takes a pattern buffer as an argument. You must
-initialize the following fields:
-
-`translate initialization'
-`translate'
- Initialize this to point to a translate table if you want one, or
- to zero if you don't. We explain translate tables in *Note GNU
- Translate Tables::.
-
-`fastmap'
- Initialize this to nonzero if you want a fastmap, or to zero if you
- don't.
-
-`buffer'
-`allocated'
- If you want `re_compile_pattern' to allocate memory for the
- compiled pattern, set both of these to zero. If you have an
- existing block of memory (allocated with `malloc') you want Regex
- to use, set `buffer' to its address and `allocated' to its size (in
- bytes).
-
- `re_compile_pattern' uses `realloc' to extend the space for the
- compiled pattern as necessary.
-
- To compile a pattern buffer, use:
-
- char *
- re_compile_pattern (const char *REGEX, const int REGEX_SIZE,
- struct re_pattern_buffer *PATTERN_BUFFER)
-
-REGEX is the regular expression's address, REGEX_SIZE is its length,
-and PATTERN_BUFFER is the pattern buffer's address.
-
- If `re_compile_pattern' successfully compiles the regular expression,
-it returns zero and sets `*PATTERN_BUFFER' to the compiled pattern. It
-sets the pattern buffer's fields as follows:
-
-`buffer'
- to the compiled pattern.
-
-`used'
- to the number of bytes the compiled pattern in `buffer' occupies.
-
-`syntax'
- to the current value of `re_syntax_options'.
-
-`re_nsub'
- to the number of subexpressions in REGEX.
-
-`fastmap_accurate'
- to zero on the theory that the pattern you're compiling is
- different than the one previously compiled into `buffer'; in that
- case (since you can't make a fastmap without a compiled pattern),
- `fastmap' would either contain an incompatible fastmap, or nothing
- at all.
-
- If `re_compile_pattern' can't compile REGEX, it returns an error
-string corresponding to one of the errors listed in *Note POSIX Regular
-Expression Compiling::.
-
-

-
-GNU Matching
-------------
-
- Matching the GNU way means trying to match as much of a string as
-possible starting at a position within it you specify. Once you've
-compiled a pattern into a pattern buffer (*note GNU Regular Expression
-Compiling::.), you can ask the matcher to match that pattern against a
-string using:
-
- int
- re_match (struct re_pattern_buffer *PATTERN_BUFFER,
- const char *STRING, const int SIZE,
- const int START, struct re_registers *REGS)
-
-PATTERN_BUFFER is the address of a pattern buffer containing a compiled
-pattern. STRING is the string you want to match; it can contain
-newline and null characters. SIZE is the length of that string. START
-is the string index at which you want to begin matching; the first
-character of STRING is at index zero. *Note Using Registers::, for a
-explanation of REGS; you can safely pass zero.
-
- `re_match' matches the regular expression in PATTERN_BUFFER against
-the string STRING according to the syntax in PATTERN_BUFFERS's `syntax'
-field. (*Note GNU Regular Expression Compiling::, for how to set it.)
-The function returns -1 if the compiled pattern does not match any part
-of STRING and -2 if an internal error happens; otherwise, it returns
-how many (possibly zero) characters of STRING the pattern matched.
-
- An example: suppose PATTERN_BUFFER points to a pattern buffer
-containing the compiled pattern for `a*', and STRING points to `aaaaab'
-(whereupon SIZE should be 6). Then if START is 2, `re_match' returns 3,
-i.e., `a*' would have matched the last three `a's in STRING. If START
-is 0, `re_match' returns 5, i.e., `a*' would have matched all the `a's
-in STRING. If START is either 5 or 6, it returns zero.
-
- If START is not between zero and SIZE, then `re_match' returns -1.
-
-

-
-GNU Searching
--------------
-
- "Searching" means trying to match starting at successive positions
-within a string. The function `re_search' does this.
-
- Before calling `re_search', you must compile your regular expression.
-*Note GNU Regular Expression Compiling::.
-
- Here is the function declaration:
-
- int
- re_search (struct re_pattern_buffer *PATTERN_BUFFER,
- const char *STRING, const int SIZE,
- const int START, const int RANGE,
- struct re_registers *REGS)
-
-whose arguments are the same as those to `re_match' (*note GNU
-Matching::.) except that the two arguments START and RANGE replace
-`re_match''s argument START.
-
- If RANGE is positive, then `re_search' attempts a match starting
-first at index START, then at START + 1 if that fails, and so on, up to
-START + RANGE; if RANGE is negative, then it attempts a match starting
-first at index START, then at START -1 if that fails, and so on.
-
- If START is not between zero and SIZE, then `re_search' returns -1.
-When RANGE is positive, `re_search' adjusts RANGE so that START + RANGE
-- 1 is between zero and SIZE, if necessary; that way it won't search
-outside of STRING. Similarly, when RANGE is negative, `re_search'
-adjusts RANGE so that START + RANGE + 1 is between zero and SIZE, if
-necessary.
-
- If the `fastmap' field of PATTERN_BUFFER is zero, `re_search' matches
-starting at consecutive positions; otherwise, it uses `fastmap' to make
-the search more efficient. *Note Searching with Fastmaps::.
-
- If no match is found, `re_search' returns -1. If a match is found,
-it returns the index where the match began. If an internal error
-happens, it returns -2.
-
-
-File: regex.info, Node: Matching/Searching with Split Data, Next: Searching with Fastmaps, Prev: GNU Searching, Up: GNU Regex Functions
-
-Matching and Searching with Split Data
---------------------------------------
-
- Using the functions `re_match_2' and `re_search_2', you can match or
-search in data that is divided into two strings.
-
- The function:
-
- int
- re_match_2 (struct re_pattern_buffer *BUFFER,
- const char *STRING1, const int SIZE1,
- const char *STRING2, const int SIZE2,
- const int START,
- struct re_registers *REGS,
- const int STOP)
-
-is similar to `re_match' (*note GNU Matching::.) except that you pass
-*two* data strings and sizes, and an index STOP beyond which you don't
-want the matcher to try matching. As with `re_match', if it succeeds,
-`re_match_2' returns how many characters of STRING it matched. Regard
-STRING1 and STRING2 as concatenated when you set the arguments START and
-STOP and use the contents of REGS; `re_match_2' never returns a value
-larger than SIZE1 + SIZE2.
-
- The function:
-
- int
- re_search_2 (struct re_pattern_buffer *BUFFER,
- const char *STRING1, const int SIZE1,
- const char *STRING2, const int SIZE2,
- const int START, const int RANGE,
- struct re_registers *REGS,
- const int STOP)
-
-is similarly related to `re_search'.
-
-
-File: regex.info, Node: Searching with Fastmaps, Next: GNU Translate Tables, Prev: Matching/Searching with Split Data, Up: GNU Regex Functions
-
-Searching with Fastmaps
------------------------
-
- If you're searching through a long string, you should use a fastmap.
-Without one, the searcher tries to match at consecutive positions in the
-string. Generally, most of the characters in the string could not start
-a match. It takes much longer to try matching at a given position in
-the string than it does to check in a table whether or not the
-character at that position could start a match. A "fastmap" is such a
-table.
-
- More specifically, a fastmap is an array indexed by the characters in
-your character set. Under the ASCII encoding, therefore, a fastmap has
-256 elements. If you want the searcher to use a fastmap with a given
-pattern buffer, you must allocate the array and assign the array's
-address to the pattern buffer's `fastmap' field. You either can
-compile the fastmap yourself or have `re_search' do it for you; when
-`fastmap' is nonzero, it automatically compiles a fastmap the first
-time you search using a particular compiled pattern.
-
- To compile a fastmap yourself, use:
-
- int
- re_compile_fastmap (struct re_pattern_buffer *PATTERN_BUFFER)
-
-PATTERN_BUFFER is the address of a pattern buffer. If the character C
-could start a match for the pattern, `re_compile_fastmap' makes
-`PATTERN_BUFFER->fastmap[C]' nonzero. It returns 0 if it can compile a
-fastmap and -2 if there is an internal error. For example, if `|' is
-the alternation operator and PATTERN_BUFFER holds the compiled pattern
-for `a|b', then `re_compile_fastmap' sets `fastmap['a']' and
-`fastmap['b']' (and no others).
-
- `re_search' uses a fastmap as it moves along in the string: it checks
-the string's characters until it finds one that's in the fastmap. Then
-it tries matching at that character. If the match fails, it repeats
-the process. So, by using a fastmap, `re_search' doesn't waste time
-trying to match at positions in the string that couldn't start a match.
-
- If you don't want `re_search' to use a fastmap, store zero in the
-`fastmap' field of the pattern buffer before calling `re_search'.
-
- Once you've initialized a pattern buffer's `fastmap' field, you need
-never do so again--even if you compile a new pattern in it--provided
-the way the field is set still reflects whether or not you want a
-fastmap. `re_search' will still either do nothing if `fastmap' is null
-or, if it isn't, compile a new fastmap for the new pattern.
-
-
-File: regex.info, Node: GNU Translate Tables, Next: Using Registers, Prev: Searching with Fastmaps, Up: GNU Regex Functions
-
-GNU Translate Tables
---------------------
-
- If you set the `translate' field of a pattern buffer to a translate
-table, then the GNU Regex functions to which you've passed that pattern
-buffer use it to apply a simple transformation to all the regular
-expression and string characters at which they look.
-
- A "translate table" is an array indexed by the characters in your
-character set. Under the ASCII encoding, therefore, a translate table
-has 256 elements. The array's elements are also characters in your
-character set. When the Regex functions see a character C, they use
-`translate[C]' in its place, with one exception: the character after a
-`\' is not translated. (This ensures that, the operators, e.g., `\B'
-and `\b', are always distinguishable.)
-
- For example, a table that maps all lowercase letters to the
-corresponding uppercase ones would cause the matcher to ignore
-differences in case.(1) Such a table would map all characters except
-lowercase letters to themselves, and lowercase letters to the
-corresponding uppercase ones. Under the ASCII encoding, here's how you
-could initialize such a table (we'll call it `case_fold'):
-
- for (i = 0; i < 256; i++)
- case_fold[i] = i;
- for (i = 'a'; i <= 'z'; i++)
- case_fold[i] = i - ('a' - 'A');
-
- You tell Regex to use a translate table on a given pattern buffer by
-assigning that table's address to the `translate' field of that buffer.
-If you don't want Regex to do any translation, put zero into this
-field. You'll get weird results if you change the table's contents
-anytime between compiling the pattern buffer, compiling its fastmap, and
-matching or searching with the pattern buffer.
-
- ---------- Footnotes ----------
-
- (1) A table that maps all uppercase letters to the corresponding
-lowercase ones would work just as well for this purpose.
-
-
-File: regex.info, Node: Using Registers, Next: Freeing GNU Pattern Buffers, Prev: GNU Translate Tables, Up: GNU Regex Functions
-
-Using Registers
----------------
-
- A group in a regular expression can match a (posssibly empty)
-substring of the string that regular expression as a whole matched.
-The matcher remembers the beginning and end of the substring matched by
-each group.
-
- To find out what they matched, pass a nonzero REGS argument to a GNU
-matching or searching function (*note GNU Matching::. and *Note GNU
-Searching::), i.e., the address of a structure of this type, as defined
-in `regex.h':
-
- struct re_registers
- {
- unsigned num_regs;
- regoff_t *start;
- regoff_t *end;
- };
-
- Except for (possibly) the NUM_REGS'th element (see below), the Ith
-element of the `start' and `end' arrays records information about the
-Ith group in the pattern. (They're declared as C pointers, but this is
-only because not all C compilers accept zero-length arrays;
-conceptually, it is simplest to think of them as arrays.)
-
- The `start' and `end' arrays are allocated in various ways, depending
-on the value of the `regs_allocated' field in the pattern buffer passed
-to the matcher.
-
- The simplest and perhaps most useful is to let the matcher
-(re)allocate enough space to record information for all the groups in
-the regular expression. If `regs_allocated' is `REGS_UNALLOCATED', the
-matcher allocates 1 + RE_NSUB (another field in the pattern buffer;
-*note GNU Pattern Buffers::.). The extra element is set to -1, and
-sets `regs_allocated' to `REGS_REALLOCATE'. Then on subsequent calls
-with the same pattern buffer and REGS arguments, the matcher
-reallocates more space if necessary.
-
- It would perhaps be more logical to make the `regs_allocated' field
-part of the `re_registers' structure, instead of part of the pattern
-buffer. But in that case the caller would be forced to initialize the
-structure before passing it. Much existing code doesn't do this
-initialization, and it's arguably better to avoid it anyway.
-
- `re_compile_pattern' sets `regs_allocated' to `REGS_UNALLOCATED', so
-if you use the GNU regular expression functions, you get this behavior
-by default.
-
- xx document re_set_registers
-
- POSIX, on the other hand, requires a different interface: the caller
-is supposed to pass in a fixed-length array which the matcher fills.
-Therefore, if `regs_allocated' is `REGS_FIXED' the matcher simply fills
-that array.
-
- The following examples illustrate the information recorded in the
-`re_registers' structure. (In all of them, `(' represents the
-open-group and `)' the close-group operator. The first character in
-the string STRING is at index 0.)
-
- * If the regular expression has an I-th group not contained within
- another group that matches a substring of STRING, then the
- function sets `REGS->start[I]' to the index in STRING where the
- substring matched by the I-th group begins, and `REGS->end[I]' to
- the index just beyond that substring's end. The function sets
- `REGS->start[0]' and `REGS->end[0]' to analogous information about
- the entire pattern.
-
- For example, when you match `((a)(b))' against `ab', you get:
-
- * 0 in `REGS->start[0]' and 2 in `REGS->end[0]'
-
- * 0 in `REGS->start[1]' and 2 in `REGS->end[1]'
-
- * 0 in `REGS->start[2]' and 1 in `REGS->end[2]'
-
- * 1 in `REGS->start[3]' and 2 in `REGS->end[3]'
-
- * If a group matches more than once (as it might if followed by,
- e.g., a repetition operator), then the function reports the
- information about what the group *last* matched.
-
- For example, when you match the pattern `(a)*' against the string
- `aa', you get:
-
- * 0 in `REGS->start[0]' and 2 in `REGS->end[0]'
-
- * 1 in `REGS->start[1]' and 2 in `REGS->end[1]'
-
- * If the I-th group does not participate in a successful match,
- e.g., it is an alternative not taken or a repetition operator
- allows zero repetitions of it, then the function sets
- `REGS->start[I]' and `REGS->end[I]' to -1.
-
- For example, when you match the pattern `(a)*b' against the string
- `b', you get:
-
- * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'
-
- * -1 in `REGS->start[1]' and -1 in `REGS->end[1]'
-
- * If the I-th group matches a zero-length string, then the function
- sets `REGS->start[I]' and `REGS->end[I]' to the index just beyond
- that zero-length string.
-
- For example, when you match the pattern `(a*)b' against the string
- `b', you get:
-
- * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'
-
- * 0 in `REGS->start[1]' and 0 in `REGS->end[1]'
-
- * If an I-th group contains a J-th group in turn not contained
- within any other group within group I and the function reports a
- match of the I-th group, then it records in `REGS->start[J]' and
- `REGS->end[J]' the last match (if it matched) of the J-th group.
-
- For example, when you match the pattern `((a*)b)*' against the
- string `abb', group 2 last matches the empty string, so you get
- what it previously matched:
-
- * 0 in `REGS->start[0]' and 3 in `REGS->end[0]'
-
- * 2 in `REGS->start[1]' and 3 in `REGS->end[1]'
-
- * 2 in `REGS->start[2]' and 2 in `REGS->end[2]'
-
- When you match the pattern `((a)*b)*' against the string `abb',
- group 2 doesn't participate in the last match, so you get:
-
- * 0 in `REGS->start[0]' and 3 in `REGS->end[0]'
-
- * 2 in `REGS->start[1]' and 3 in `REGS->end[1]'
-
- * 0 in `REGS->start[2]' and 1 in `REGS->end[2]'
-
- * If an I-th group contains a J-th group in turn not contained
- within any other group within group I and the function sets
- `REGS->start[I]' and `REGS->end[I]' to -1, then it also sets
- `REGS->start[J]' and `REGS->end[J]' to -1.
-
- For example, when you match the pattern `((a)*b)*c' against the
- string `c', you get:
-
- * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'
-
- * -1 in `REGS->start[1]' and -1 in `REGS->end[1]'
-
- * -1 in `REGS->start[2]' and -1 in `REGS->end[2]'

-Freeing GNU Pattern Buffers
----------------------------
-
- To free any allocated fields of a pattern buffer, you can use the
-POSIX function described in *Note Freeing POSIX Pattern Buffers::,
-since the type `regex_t'--the type for POSIX pattern buffers--is
-equivalent to the type `re_pattern_buffer'. After freeing a pattern
-buffer, you need to again compile a regular expression in it (*note GNU
-Regular Expression Compiling::.) before passing it to a matching or
-searching function.

-POSIX Pattern Buffers
----------------------
-
- To compile or match a given regular expression the POSIX way, you
-must supply a pattern buffer exactly the way you do for GNU (*note GNU
-Pattern Buffers::.). POSIX pattern buffers have type `regex_t', which
-is equivalent to the GNU pattern buffer type `re_pattern_buffer'.
-
-
-File: regex.info, Node: POSIX Regular Expression Compiling, Next: POSIX Matching, Prev: POSIX Pattern Buffers, Up: POSIX Regex Functions
-
-POSIX Regular Expression Compiling
-----------------------------------
-
- With POSIX, you can only search for a given regular expression; you
-can't match it. To do this, you must first compile it in a pattern
-buffer, using `regcomp'.
-
- To compile a pattern buffer, use:
-
- int
- regcomp (regex_t *PREG, const char *REGEX, int CFLAGS)
-
-PREG is the initialized pattern buffer's address, REGEX is the regular
-expression's address, and CFLAGS is the compilation flags, which Regex
-considers as a collection of bits. Here are the valid bits, as defined
-in `regex.h':
-
-`REG_EXTENDED'
- says to use POSIX Extended Regular Expression syntax; if this isn't
- set, then says to use POSIX Basic Regular Expression syntax.
- `regcomp' sets PREG's `syntax' field accordingly.
-
-`REG_ICASE'
- says to ignore case; `regcomp' sets PREG's `translate' field to a
- translate table which ignores case, replacing anything you've put
- there before.
-
-`REG_NOSUB'
- says to set PREG's `no_sub' field; *note POSIX Matching::., for
- what this means.
-
-`REG_NEWLINE'
- says that a:
-
- * match-any-character operator (*note Match-any-character
- Operator::.) doesn't match a newline.
-
- * nonmatching list not containing a newline (*note List
- Operators::.) matches a newline.
-
- * match-beginning-of-line operator (*note
- Match-beginning-of-line Operator::.) matches the empty string
- immediately after a newline, regardless of how `REG_NOTBOL'
- is set (*note POSIX Matching::., for an explanation of
- `REG_NOTBOL').
-
- * match-end-of-line operator (*note Match-beginning-of-line
- Operator::.) matches the empty string immediately before a
- newline, regardless of how `REG_NOTEOL' is set (*note POSIX
- Matching::., for an explanation of `REG_NOTEOL').
-
- If `regcomp' successfully compiles the regular expression, it returns
-zero and sets `*PATTERN_BUFFER' to the compiled pattern. Except for
-`syntax' (which it sets as explained above), it also sets the same
-fields the same way as does the GNU compiling function (*note GNU
-Regular Expression Compiling::.).
-
- If `regcomp' can't compile the regular expression, it returns one of
-the error codes listed here. (Except when noted differently, the
-syntax of in all examples below is basic regular expression syntax.)
-
-`REG_BADRPT'
- For example, the consecutive repetition operators `**' in `a**'
- are invalid. As another example, if the syntax is extended
- regular expression syntax, then the repetition operator `*' with
- nothing on which to operate in `*' is invalid.
-
-`REG_BADBR'
- For example, the COUNT `-1' in `a\{-1' is invalid.
-
-`REG_EBRACE'
- For example, `a\{1' is missing a close-interval operator.
-
-`REG_EBRACK'
- For example, `[a' is missing a close-list operator.
-
-`REG_ERANGE'
- For example, the range ending point `z' that collates lower than
- does its starting point `a' in `[z-a]' is invalid. Also, the
- range with the character class `[:alpha:]' as its starting point in
- `[[:alpha:]-|]'.
-
-`REG_ECTYPE'
- For example, the character class name `foo' in `[[:foo:]' is
- invalid.
-
-`REG_EPAREN'
- For example, `a\)' is missing an open-group operator and `\(a' is
- missing a close-group operator.
-
-`REG_ESUBREG'
- For example, the back reference `\2' that refers to a nonexistent
- subexpression in `\(a\)\2' is invalid.
-
-`REG_EEND'
- Returned when a regular expression causes no other more specific
- error.
-
-`REG_EESCAPE'
- For example, the trailing backslash `\' in `a\' is invalid, as is
- the one in `\'.
-
-`REG_BADPAT'
- For example, in the extended regular expression syntax, the empty
- group `()' in `a()b' is invalid.
-
-`REG_ESIZE'
- Returned when a regular expression needs a pattern buffer larger
- than 65536 bytes.
-
-`REG_ESPACE'
- Returned when a regular expression makes Regex to run out of
- memory.
-
-
-File: regex.info, Node: POSIX Matching, Next: Reporting Errors, Prev: POSIX Regular Expression Compiling, Up: POSIX Regex Functions
-
-POSIX Matching
---------------
-
- Matching the POSIX way means trying to match a null-terminated string
-starting at its first character. Once you've compiled a pattern into a
-pattern buffer (*note POSIX Regular Expression Compiling::.), you can
-ask the matcher to match that pattern against a string using:
-
- int
- regexec (const regex_t *PREG, const char *STRING,
- size_t NMATCH, regmatch_t PMATCH[], int EFLAGS)
-
-PREG is the address of a pattern buffer for a compiled pattern. STRING
-is the string you want to match.
-
- *Note Using Byte Offsets::, for an explanation of PMATCH. If you
-pass zero for NMATCH or you compiled PREG with the compilation flag
-`REG_NOSUB' set, then `regexec' will ignore PMATCH; otherwise, you must
-allocate it to have at least NMATCH elements. `regexec' will record
-NMATCH byte offsets in PMATCH, and set to -1 any unused elements up to
-PMATCH`[NMATCH]' - 1.
-
- EFLAGS specifies "execution flags"--namely, the two bits `REG_NOTBOL'
-and `REG_NOTEOL' (defined in `regex.h'). If you set `REG_NOTBOL', then
-the match-beginning-of-line operator (*note Match-beginning-of-line
-Operator::.) always fails to match. This lets you match against pieces
-of a line, as you would need to if, say, searching for repeated
-instances of a given pattern in a line; it would work correctly for
-patterns both with and without match-beginning-of-line operators.
-`REG_NOTEOL' works analogously for the match-end-of-line operator
-(*note Match-end-of-line Operator::.); it exists for symmetry.
-
- `regexec' tries to find a match for PREG in STRING according to the
-syntax in PREG's `syntax' field. (*Note POSIX Regular Expression
-Compiling::, for how to set it.) The function returns zero if the
-compiled pattern matches STRING and `REG_NOMATCH' (defined in
-`regex.h') if it doesn't.
-
-
-File: regex.info, Node: Reporting Errors, Next: Using Byte Offsets, Prev: POSIX Matching, Up: POSIX Regex Functions
-
-Reporting Errors
-----------------
-
- If either `regcomp' or `regexec' fail, they return a nonzero error
-code, the possibilities for which are defined in `regex.h'. *Note
-POSIX Regular Expression Compiling::, and *Note POSIX Matching::, for
-what these codes mean. To get an error string corresponding to these
-codes, you can use:
-
- size_t
- regerror (int ERRCODE,
- const regex_t *PREG,
- char *ERRBUF,
- size_t ERRBUF_SIZE)
-
-ERRCODE is an error code, PREG is the address of the pattern buffer
-which provoked the error, ERRBUF is the error buffer, and ERRBUF_SIZE
-is ERRBUF's size.
-
- `regerror' returns the size in bytes of the error string
-corresponding to ERRCODE (including its terminating null). If ERRBUF
-and ERRBUF_SIZE are nonzero, it also returns in ERRBUF the first
-ERRBUF_SIZE - 1 characters of the error string, followed by a null.
-eRRBUF_SIZE must be a nonnegative number less than or equal to the size
-in bytes of ERRBUF.
-
- You can call `regerror' with a null ERRBUF and a zero ERRBUF_SIZE to
-determine how large ERRBUF need be to accommodate `regerror''s error
-string.

-
-Using Byte Offsets
-------------------
-
- In POSIX, variables of type `regmatch_t' hold analogous information,
-but are not identical to, GNU's registers (*note Using Registers::.).
-To get information about registers in POSIX, pass to `regexec' a
-nonzero PMATCH of type `regmatch_t', i.e., the address of a structure
-of this type, defined in `regex.h':
-
- typedef struct
- {
- regoff_t rm_so;
- regoff_t rm_eo;
- } regmatch_t;
-
- When reading in *Note Using Registers::, about how the matching
-function stores the information into the registers, substitute PMATCH
-for REGS, `PMATCH[I]->rm_so' for `REGS->start[I]' and
-`PMATCH[I]->rm_eo' for `REGS->end[I]'.

-
-Freeing POSIX Pattern Buffers
------------------------------
-
- To free any allocated fields of a pattern buffer, use:
-
- void
- regfree (regex_t *PREG)
-
-PREG is the pattern buffer whose allocated fields you want freed.
-`regfree' also sets PREG's `allocated' and `used' fields to zero.
-After freeing a pattern buffer, you need to again compile a regular
-expression in it (*note POSIX Regular Expression Compiling::.) before
-passing it to the matching function (*note POSIX Matching::.).

-BSD Regex Functions
-===================
-
- If you're writing code that has to be Berkeley UNIX compatible,
-you'll need to use these functions whose interfaces are the same as
-those in Berkeley UNIX.
-
-* Menu:
-
-* BSD Regular Expression Compiling:: re_comp ()
-* BSD Searching:: re_exec ()
-
-
-File: regex.info, Node: BSD Regular Expression Compiling, Next: BSD Searching, Up: BSD Regex Functions
-
-BSD Regular Expression Compiling
---------------------------------
-
- With Berkeley UNIX, you can only search for a given regular
-expression; you can't match one. To search for it, you must first
-compile it. Before you compile it, you must indicate the regular
-expression syntax you want it compiled according to by setting the
-variable `re_syntax_options' (declared in `regex.h' to some syntax
-(*note Regular Expression Syntax::.).
-
- To compile a regular expression use:
-
- char *
- re_comp (char *REGEX)
-
-REGEX is the address of a null-terminated regular expression.
-`re_comp' uses an internal pattern buffer, so you can use only the most
-recently compiled pattern buffer. This means that if you want to use a
-given regular expression that you've already compiled--but it isn't the
-latest one you've compiled--you'll have to recompile it. If you call
-`re_comp' with the null string (*not* the empty string) as the
-argument, it doesn't change the contents of the pattern buffer.
-
- If `re_comp' successfully compiles the regular expression, it returns
-zero. If it can't compile the regular expression, it returns an error
-string. `re_comp''s error messages are identical to those of
-`re_compile_pattern' (*note GNU Regular Expression Compiling::.).
-
-
-File: regex.info, Node: BSD Searching, Prev: BSD Regular Expression Compiling, Up: BSD Regex Functions
-
-BSD Searching
--------------
-
- Searching the Berkeley UNIX way means searching in a string starting
-at its first character and trying successive positions within it to
-find a match. Once you've compiled a pattern using `re_comp' (*note
-BSD Regular Expression Compiling::.), you can ask Regex to search for
-that pattern in a string using:
-
- int
- re_exec (char *STRING)
-
-STRING is the address of the null-terminated string in which you want
-to search.
-
- `re_exec' returns either 1 for success or 0 for failure. It
-automatically uses a GNU fastmap (*note Searching with Fastmaps::.).

- of this license document, but changing it is not allowed.
-
-Preamble
-========
-
- The licenses for most software are designed to take away your freedom
-to share and change it. By contrast, the GNU General Public License is
-intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it in
-new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 1. This License applies to any program or other work which contains a
- notice placed by the copyright holder saying it may be distributed
- under the terms of this General Public License. The "Program",
- below, refers to any such program or work, and a "work based on
- the Program" means either the Program or any derivative work under
- copyright law: that is to say, a work containing the Program or a
- portion of it, either verbatim or with modifications and/or
- translated into another language. (Hereinafter, translation is
- included without limitation in the term "modification".) Each
- licensee is addressed as "you".
-
- Activities other than copying, distribution and modification are
- not covered by this License; they are outside its scope. The act
- of running the Program is not restricted, and the output from the
- Program is covered only if its contents constitute a work based on
- the Program (independent of having been made by running the
- Program). Whether that is true depends on what the Program does.
-
- 2. You may copy and distribute verbatim copies of the Program's
- source code as you receive it, in any medium, provided that you
- conspicuously and appropriately publish on each copy an appropriate
- copyright notice and disclaimer of warranty; keep intact all the
- notices that refer to this License and to the absence of any
- warranty; and give any other recipients of the Program a copy of
- this License along with the Program.
-
- You may charge a fee for the physical act of transferring a copy,
- and you may at your option offer warranty protection in exchange
- for a fee.
-
- 3. You may modify your copy or copies of the Program or any portion
- of it, thus forming a work based on the Program, and copy and
- distribute such modifications or work under the terms of Section 1
- above, provided that you also meet all of these conditions:
-
- a. You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b. You must cause any work that you distribute or publish, that
- in whole or in part contains or is derived from the Program
- or any part thereof, to be licensed as a whole at no charge
- to all third parties under the terms of this License.
-
- c. If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display
- an announcement including an appropriate copyright notice and
- a notice that there is no warranty (or else, saying that you
- provide a warranty) and that users may redistribute the
- program under these conditions, and telling the user how to
- view a copy of this License. (Exception: if the Program
- itself is interactive but does not normally print such an
- announcement, your work based on the Program is not required
- to print an announcement.)
-
- These requirements apply to the modified work as a whole. If
- identifiable sections of that work are not derived from the
- Program, and can be reasonably considered independent and separate
- works in themselves, then this License, and its terms, do not
- apply to those sections when you distribute them as separate
- works. But when you distribute the same sections as part of a
- whole which is a work based on the Program, the distribution of
- the whole must be on the terms of this License, whose permissions
- for other licensees extend to the entire whole, and thus to each
- and every part regardless of who wrote it.
-
- Thus, it is not the intent of this section to claim rights or
- contest your rights to work written entirely by you; rather, the
- intent is to exercise the right to control the distribution of
- derivative or collective works based on the Program.
-
- In addition, mere aggregation of another work not based on the
- Program with the Program (or with a work based on the Program) on
- a volume of a storage or distribution medium does not bring the
- other work under the scope of this License.
-
- 4. You may copy and distribute the Program (or a work based on it,
- under Section 2) in object code or executable form under the terms
- of Sections 1 and 2 above provided that you also do one of the
- following:
-
- a. Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of
- Sections 1 and 2 above on a medium customarily used for
- software interchange; or,
-
- b. Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a
- medium customarily used for software interchange; or,
-
- c. Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with
- such an offer, in accord with Subsection b above.)
-
- The source code for a work means the preferred form of the work for
- making modifications to it. For an executable work, complete
- source code means all the source code for all modules it contains,
- plus any associated interface definition files, plus the scripts
- used to control compilation and installation of the executable.
- However, as a special exception, the source code distributed need
- not include anything that is normally distributed (in either
- source or binary form) with the major components (compiler,
- kernel, and so on) of the operating system on which the executable
- runs, unless that component itself accompanies the executable.
-
- If distribution of executable or object code is made by offering
- access to copy from a designated place, then offering equivalent
- access to copy the source code from the same place counts as
- distribution of the source code, even though third parties are not
- compelled to copy the source along with the object code.
-
- 5. You may not copy, modify, sublicense, or distribute the Program
- except as expressly provided under this License. Any attempt
- otherwise to copy, modify, sublicense or distribute the Program is
- void, and will automatically terminate your rights under this
- License. However, parties who have received copies, or rights,
- from you under this License will not have their licenses
- terminated so long as such parties remain in full compliance.
-
- 6. You are not required to accept this License, since you have not
- signed it. However, nothing else grants you permission to modify
- or distribute the Program or its derivative works. These actions
- are prohibited by law if you do not accept this License.
- Therefore, by modifying or distributing the Program (or any work
- based on the Program), you indicate your acceptance of this
- License to do so, and all its terms and conditions for copying,
- distributing or modifying the Program or works based on it.
-
- 7. Each time you redistribute the Program (or any work based on the
- Program), the recipient automatically receives a license from the
- original licensor to copy, distribute or modify the Program
- subject to these terms and conditions. You may not impose any
- further restrictions on the recipients' exercise of the rights
- granted herein. You are not responsible for enforcing compliance
- by third parties to this License.
-
- 8. If, as a consequence of a court judgment or allegation of patent
- infringement or for any other reason (not limited to patent
- issues), conditions are imposed on you (whether by court order,
- agreement or otherwise) that contradict the conditions of this
- License, they do not excuse you from the conditions of this
- License. If you cannot distribute so as to satisfy simultaneously
- your obligations under this License and any other pertinent
- obligations, then as a consequence you may not distribute the
- Program at all. For example, if a patent license would not permit
- royalty-free redistribution of the Program by all those who
- receive copies directly or indirectly through you, then the only
- way you could satisfy both it and this License would be to refrain
- entirely from distribution of the Program.
-
- If any portion of this section is held invalid or unenforceable
- under any particular circumstance, the balance of the section is
- intended to apply and the section as a whole is intended to apply
- in other circumstances.
-
- It is not the purpose of this section to induce you to infringe any
- patents or other property right claims or to contest validity of
- any such claims; this section has the sole purpose of protecting
- the integrity of the free software distribution system, which is
- implemented by public license practices. Many people have made
- generous contributions to the wide range of software distributed
- through that system in reliance on consistent application of that
- system; it is up to the author/donor to decide if he or she is
- willing to distribute software through any other system and a
- licensee cannot impose that choice.
-
- This section is intended to make thoroughly clear what is believed
- to be a consequence of the rest of this License.
-
- 9. If the distribution and/or use of the Program is restricted in
- certain countries either by patents or by copyrighted interfaces,
- the original copyright holder who places the Program under this
- License may add an explicit geographical distribution limitation
- excluding those countries, so that distribution is permitted only
- in or among countries not thus excluded. In such case, this
- License incorporates the limitation as if written in the body of
- this License.
-
- 10. The Free Software Foundation may publish revised and/or new
- versions of the General Public License from time to time. Such
- new versions will be similar in spirit to the present version, but
- may differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
- Program specifies a version number of this License which applies
- to it and "any later version", you have the option of following
- the terms and conditions either of that version or of any later
- version published by the Free Software Foundation. If the Program
- does not specify a version number of this License, you may choose
- any version ever published by the Free Software Foundation.
-
- 11. If you wish to incorporate parts of the Program into other free
- programs whose distribution conditions are different, write to the
- author to ask for permission. For software which is copyrighted
- by the Free Software Foundation, write to the Free Software
- Foundation; we sometimes make exceptions for this. Our decision
- will be guided by the two goals of preserving the free status of
- all derivatives of our free software and of promoting the sharing
- and reuse of software generally.
-
- NO WARRANTY
-
- 12. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
- WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
- LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
- HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
- WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
- NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
- FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
- QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
- PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
- SERVICING, REPAIR OR CORRECTION.
-
- 13. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
- WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
- MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
- LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
- INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
- INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
- DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU

-Appendix: How to Apply These Terms to Your New Programs
-=======================================================
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
- Copyright (C) 19YY NAME OF AUTHOR
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
- Also add information on how to contact you by electronic and paper
-mail.
-
- If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
- The hypothetical commands `show w' and `show c' should show the
-appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than `show w' and `show
-c'; they could even be mouse-clicks or menu items--whatever suits your
-program.
-
- You should also get your employer (if you work as a programmer) or
-your school, if any, to sign a "copyright disclaimer" for the program,
-if necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- SIGNATURE OF TY COON, 1 April 1989
- Ty Coon, President of Vice
-
- This General Public License does not permit incorporating your
-program into proprietary programs. If your program is a subroutine
-library, you may consider it more useful to permit linking proprietary
-applications with the library. If this is what you want to do, use the
-GNU Library General Public License instead of this License.

-@chapter Overview
-
-A @dfn{regular expression} (or @dfn{regexp}, or @dfn{pattern}) is a text
-string that describes some (mathematical) set of strings. A regexp
-@var{r} @dfn{matches} a string @var{s} if @var{s} is in the set of
-strings described by @var{r}.
-
-Using the Regex library, you can:
-
-@itemize @bullet
-
-@item
-see if a string matches a specified pattern as a whole, and
-
-@item
-search within a string for a substring matching a specified pattern.
-
-@end itemize
-
-Some regular expressions match only one string, i.e., the set they
-describe has only one member. For example, the regular expression
-@samp{foo} matches the string @samp{foo} and no others. Other regular
-expressions match more than one string, i.e., the set they describe has
-more than one member. For example, the regular expression @samp{f*}
-matches the set of strings made up of any number (including zero) of
-@samp{f}s. As you can see, some characters in regular expressions match
-themselves (such as @samp{f}) and some don't (such as @samp{*}); the
-ones that don't match themselves instead let you specify patterns that
-describe many different strings.
-
-To either match or search for a regular expression with the Regex
-library functions, you must first compile it with a Regex pattern
-compiling function. A @dfn{compiled pattern} is a regular expression
-converted to the internal format used by the library functions. Once
-you've compiled a pattern, you can use it for matching or searching any
-number of times.
-
-The Regex library consists of two source files: @file{regex.h} and
-@file{regex.c}.
-@pindex regex.h
-@pindex regex.c
-Regex provides three groups of functions with which you can operate on
-regular expressions. One group---the @sc{gnu} group---is more powerful
-but not completely compatible with the other two, namely the @sc{posix}
-and Berkeley @sc{unix} groups; its interface was designed specifically
-for @sc{gnu}. The other groups have the same interfaces as do the
-regular expression functions in @sc{posix} and Berkeley
-@sc{unix}.
-
-We wrote this chapter with programmers in mind, not users of
-programs---such as Emacs---that use Regex. We describe the Regex
-library in its entirety, not how to write regular expressions that a
-particular program understands.
-

-
-@cindex regular expressions, syntax of
-@cindex syntax of regular expressions
-
-@dfn{Characters} are things you can type. @dfn{Operators} are things in
-a regular expression that match one or more characters. You compose
-regular expressions from operators, which in turn you specify using one
-or more characters.
-
-Most characters represent what we call the match-self operator, i.e.,
-they match themselves; we call these characters @dfn{ordinary}. Other
-characters represent either all or parts of fancier operators; e.g.,
-@samp{.} represents what we call the match-any-character operator
-(which, no surprise, matches (almost) any character); we call these
-characters @dfn{special}. Two different things determine what
-characters represent what operators:
-
-@enumerate
-@item
-the regular expression syntax your program has told the Regex library to
-recognize, and
-
-@item
-the context of the character in the regular expression.
-@end enumerate
-
-In the following sections, we describe these things in more detail.

-@section Syntax Bits
-
-@cindex syntax bits
-
-In any particular syntax for regular expressions, some characters are
-always special, others are sometimes special, and others are never
-special. The particular syntax that Regex recognizes for a given
-regular expression depends on the value in the @code{syntax} field of
-the pattern buffer of that regular expression.
-
-You get a pattern buffer by compiling a regular expression. @xref{GNU
-Pattern Buffers}, and @ref{POSIX Pattern Buffers}, for more information
-on pattern buffers. @xref{GNU Regular Expression Compiling}, @ref{POSIX
-Regular Expression Compiling}, and @ref{BSD Regular Expression
-Compiling}, for more information on compiling.
-
-Regex considers the value of the @code{syntax} field to be a collection
-of bits; we refer to these bits as @dfn{syntax bits}. In most cases,
-they affect what characters represent what operators. We describe the
-meanings of the operators to which we refer in @ref{Common Operators},
-@ref{GNU Operators}, and @ref{GNU Emacs Operators}.
-
-For reference, here is the complete list of syntax bits, in alphabetical
-order:
-
-@table @code
-
-@cnindex RE_BACKSLASH_ESCAPE_IN_LIST
-@item RE_BACKSLASH_ESCAPE_IN_LISTS
-If this bit is set, then @samp{\} inside a list (@pxref{List Operators}
-quotes (makes ordinary, if it's special) the following character; if
-this bit isn't set, then @samp{\} is an ordinary character inside lists.
-(@xref{The Backslash Character}, for what `\' does outside of lists.)
-
-@cnindex RE_BK_PLUS_QM
-@item RE_BK_PLUS_QM
-If this bit is set, then @samp{\+} represents the match-one-or-more
-operator and @samp{\?} represents the match-zero-or-more operator; if
-this bit isn't set, then @samp{+} represents the match-one-or-more
-operator and @samp{?} represents the match-zero-or-one operator. This
-bit is irrelevant if @code{RE_LIMITED_OPS} is set.
-
-@cnindex RE_CHAR_CLASSES
-@item RE_CHAR_CLASSES
-If this bit is set, then you can use character classes in lists; if this
-bit isn't set, then you can't.
-
-@cnindex RE_CONTEXT_INDEP_ANCHORS
-@item RE_CONTEXT_INDEP_ANCHORS
-If this bit is set, then @samp{^} and @samp{$} are special anywhere outside
-a list; if this bit isn't set, then these characters are special only in
-certain contexts. @xref{Match-beginning-of-line Operator}, and
-@ref{Match-end-of-line Operator}.
-
-@cnindex RE_CONTEXT_INDEP_OPS
-@item RE_CONTEXT_INDEP_OPS
-If this bit is set, then certain characters are special anywhere outside
-a list; if this bit isn't set, then those characters are special only in
-some contexts and are ordinary elsewhere. Specifically, if this bit
-isn't set then @samp{*}, and (if the syntax bit @code{RE_LIMITED_OPS}
-isn't set) @samp{+} and @samp{?} (or @samp{\+} and @samp{\?}, depending
-on the syntax bit @code{RE_BK_PLUS_QM}) represent repetition operators
-only if they're not first in a regular expression or just after an
-open-group or alternation operator. The same holds for @samp{@{} (or
-@samp{\@{}, depending on the syntax bit @code{RE_NO_BK_BRACES}) if
-it is the beginning of a valid interval and the syntax bit
-@code{RE_INTERVALS} is set.
-
-@cnindex RE_CONTEXT_INVALID_OPS
-@item RE_CONTEXT_INVALID_OPS
-If this bit is set, then repetition and alternation operators can't be
-in certain positions within a regular expression. Specifically, the
-regular expression is invalid if it has:
-
-@itemize @bullet
-
-@item
-a repetition operator first in the regular expression or just after a
-match-beginning-of-line, open-group, or alternation operator; or
-
-@item
-an alternation operator first or last in the regular expression, just
-before a match-end-of-line operator, or just after an alternation or
-open-group operator.
-
-@end itemize
-
-If this bit isn't set, then you can put the characters representing the
-repetition and alternation characters anywhere in a regular expression.
-Whether or not they will in fact be operators in certain positions
-depends on other syntax bits.
-
-@cnindex RE_DOT_NEWLINE
-@item RE_DOT_NEWLINE
-If this bit is set, then the match-any-character operator matches
-a newline; if this bit isn't set, then it doesn't.
-
-@cnindex RE_DOT_NOT_NULL
-@item RE_DOT_NOT_NULL
-If this bit is set, then the match-any-character operator doesn't match
-a null character; if this bit isn't set, then it does.
-
-@cnindex RE_INTERVALS

-@section Collating Elements vs.@: Characters
-
-@sc{posix} generalizes the notion of a character to that of a
-collating element. It defines a @dfn{collating element} to be ``a
-sequence of one or more bytes defined in the current collating sequence
-as a unit of collation.''
-
-This generalizes the notion of a character in
-two ways. First, a single character can map into two or more collating
-elements. For example, the German
-@tex
-`\ss'
-@end tex
-@ifinfo
-``es-zet''
-@end ifinfo
-collates as the collating element @samp{s} followed by another collating
-element @samp{s}. Second, two or more characters can map into one
-collating element. For example, the Spanish @samp{ll} collates after
-@samp{l} and before @samp{m}.
-
-Since @sc{posix}'s ``collating element'' preserves the essential idea of
-a ``character,'' we use the latter, more familiar, term in this document.

-aren't set, then (for historical reasons) the matcher considers special
-characters ordinary if they are in contexts where the operations they
-represent make no sense; for example, then the match-zero-or-more
-operator (represented by @samp{*}) matches itself in the regular
-expression @samp{*foo} because there is no preceding expression on which

-as many times as necessary (including zero) to match the pattern.
-@samp{*} represents this operator. For example, @samp{o*}
-matches any string made up of zero or more @samp{o}s. Since this

-@samp{fo*} has a repeating @samp{o}, not a repeating @samp{fo}. So,
-@samp{fo*} matches @samp{f}, @samp{fo}, @samp{foo}, and so on.
-
-Since the match-zero-or-more operator is a suffix operator, it may be

-The matcher processes a match-zero-or-more operator by first matching as

-Then it continues to match the rest of the pattern.
-
-If it can't match the rest of the pattern, it backtracks (as many times
-as necessary), each time discarding one of the matches until it can
-either match the entire pattern or be certain that it cannot get a
-match. For example, when matching @samp{ca*ar} against @samp{caaar},
-the matcher first matches all three @samp{a}s of the string with the
-@samp{a*} of the regular expression. However, it cannot then match the
-final @samp{ar} of the regular expression against the final @samp{r} of
-the string. So it backtracks, discarding the match of the last @samp{a}
-in the string. It can then match the remaining @samp{ar}.

-of any of the following: characters, collating elements, collating symbols,
-and equivalence class expressions. The starting point of the range and
-the ending point of the range don't have to be the same kind of item,
-e.g., the starting point could be a collating element and the ending
-point could be an equivalence class expression. If a range's ending
-point is an equivalence class, then all the collating elements in that
-class will be in the range.
-@end ignore
-characters.@footnote{You can't use a character class for the starting
-or ending point of a range, since a character class is not a single
-character.} @samp{-} represents the range operator. For example,
-@samp{a-f} within a list represents all the characters from @samp{a}
-through @samp{f}
-inclusively.
-
-If the syntax bit @code{RE_NO_EMPTY_RANGES} is set, then if the range's
-ending point collates less than its starting point, the range (and the
-regular expression containing it) is invalid. For example, the regular
-expression @samp{[z-a]} would be invalid. If this bit isn't set, then
-Regex considers such a range to be empty.
-
-Since @samp{-} represents the range operator, if you want to make a
-@samp{-} character itself
-a list item, you must do one of the following:
-
-@itemize @bullet
-@item
-Put the @samp{-} either first or last in the list.
-
-@item
-Include a range whose starting point collates strictly lower than
-@samp{-} and whose ending point collates equal or higher. Unless a
-range is the first item in a list, a @samp{-} can't be its starting
-point, but @emph{can} be its ending point. That is because Regex
-considers @samp{-} to be the range operator unless it is preceded by
-another @samp{-}. For example, in the @sc{ascii} encoding, @samp{)},
-@samp{*}, @samp{+}, @samp{,}, @samp{-}, @samp{.}, and @samp{/} are
-contiguous characters in the collating sequence. You might think that
-@samp{[)-+--/]} has two ranges: @samp{)-+} and @samp{--/}. Rather, it
-has the ranges @samp{)-+} and @samp{+--}, plus the character @samp{/}, so
-it matches, e.g., @samp{,}, not @samp{.}.

-
-@cindex back references
-
-If the syntax bit @code{RE_NO_BK_REF} isn't set, then Regex recognizes
-back references. A back reference matches a specified preceding group.
-The back reference operator is represented by @samp{\@var{digit}}
-anywhere after the end of a regular expression's @w{@var{digit}-th}
-group (@pxref{Grouping Operators}).
-
-@var{digit} must be between @samp{1} and @samp{9}. The matcher assigns
-numbers 1 through 9 to the first nine groups it encounters. By using
-one of @samp{\1} through @samp{\9} after the corresponding group's
-close-group operator, you can match a substring identical to the
-one that the group does.
-
-Back references match according to the following (in all examples below,
-@samp{(} represents the open-group, @samp{)} the close-group, @samp{@{}
-the open-interval and @samp{@}} the close-interval operator):
-
-@itemize @bullet
-@item
-If the group matches a substring, the back reference matches an
-identical substring. For example, @samp{(a)\1} matches @samp{aa} and
-@samp{(bana)na\1bo\1} matches @samp{bananabanabobana}. Likewise,
-@samp{(.*)\1} matches any (newline-free if the syntax bit
-@code{RE_DOT_NEWLINE} isn't set) string that is composed of two
-identical halves; the @samp{(.*)} matches the first half and the
-@samp{\1} matches the second half.
-
-@item
-If the group matches more than once (as it might if followed
-by, e.g., a repetition operator), then the back reference matches the
-substring the group @emph{last} matched. For example,
-@samp{((a*)b)*\1\2} matches @samp{aabababa}; first @w{group 1} (the
-outer one) matches @samp{aab} and @w{group 2} (the inner one) matches
-@samp{aa}. Then @w{group 1} matches @samp{ab} and @w{group 2} matches
-@samp{a}. So, @samp{\1} matches @samp{ab} and @samp{\2} matches
-@samp{a}.
-
-@item
-If the group doesn't participate in a match, i.e., it is part of an
-alternative not taken or a repetition operator allows zero repetitions
-of it, then the back reference makes the whole match fail. For example,
-@samp{(one()|two())-and-(three\2|four\3)} matches @samp{one-and-three}
-and @samp{two-and-four}, but not @samp{one-and-four} or
-@samp{two-and-three}. For example, if the pattern matches
-@samp{one-and-}, then its @w{group 2} matches the empty string and its
-@w{group 3} doesn't participate in the match. So, if it then matches
-@samp{four}, then when it tries to back reference @w{group 3}---which it
-will attempt to do because @samp{\3} follows the @samp{four}---the match
-will fail because @w{group 3} didn't participate in the match.
-
-@end itemize
-
-You can use a back reference as an argument to a repetition operator. For
-example, @samp{(a(b))\2*} matches @samp{a} followed by two or more
-@samp{b}s. Similarly, @samp{(a(b))\2@{3@}} matches @samp{abbbb}.
-
-If there is no preceding @w{@var{digit}-th} subexpression, the regular
-expression is invalid.

-To compile, match, or search for a given regular expression, you must
-supply a pattern buffer. A @dfn{pattern buffer} holds one compiled
-regular expression.@footnote{Regular expressions are also referred to as
-``patterns,'' hence the name ``pattern buffer.''}
-
-You can have several different pattern buffers simultaneously, each
-holding a compiled pattern for a different regular expression.
-
-@file{regex.h} defines the pattern buffer @code{struct} as follows:
-
-@example
- /* Space that holds the compiled pattern. It is declared as
- `unsigned char *' because its elements are
- sometimes used as array indexes. */
- unsigned char *buffer;
-
- /* Number of bytes to which `buffer' points. */
- unsigned long allocated;
-
- /* Number of bytes actually used in `buffer'. */
- unsigned long used;
-
- /* Syntax setting with which the pattern was compiled. */
- reg_syntax_t syntax;
-
- /* Pointer to a fastmap, if any, otherwise zero. re_search uses
- the fastmap, if there is one, to skip over impossible
- starting points for matches. */
- char *fastmap;
-
- /* Either a translate table to apply to all characters before
- comparing them, or zero for no translation. The translation
- is applied to a pattern when it is compiled and to a string
- when it is matched. */
- char *translate;
-
- /* Number of subexpressions found by the compiler. */
- size_t re_nsub;
-
- /* Zero if this pattern cannot match the empty string, one else.

-
-@cindex matching with GNU functions
-
-Matching the @sc{gnu} way means trying to match as much of a string as
-possible starting at a position within it you specify. Once you've compiled
-a pattern into a pattern buffer (@pxref{GNU Regular Expression
-Compiling}), you can ask the matcher to match that pattern against a
-string using:
-
-@findex re_match
-@example
-int
-re_match (struct re_pattern_buffer *@var{pattern_buffer},
- const char *@var{string}, const int @var{size},
- const int @var{start}, struct re_registers *@var{regs})
-@end example
-
-@noindent
-@var{pattern_buffer} is the address of a pattern buffer containing a
-compiled pattern. @var{string} is the string you want to match; it can
-contain newline and null characters. @var{size} is the length of that
-string. @var{start} is the string index at which you want to
-begin matching; the first character of @var{string} is at index zero.
-@xref{Using Registers}, for a explanation of @var{regs}; you can safely
-pass zero.
-
-@code{re_match} matches the regular expression in @var{pattern_buffer}
-against the string @var{string} according to the syntax in
-@var{pattern_buffers}'s @code{syntax} field. (@xref{GNU Regular
-Expression Compiling}, for how to set it.) The function returns
-@math{-1} if the compiled pattern does not match any part of
-@var{string} and @math{-2} if an internal error happens; otherwise, it
-returns how many (possibly zero) characters of @var{string} the pattern
-matched.
-
-An example: suppose @var{pattern_buffer} points to a pattern buffer
-containing the compiled pattern for @samp{a*}, and @var{string} points
-to @samp{aaaaab} (whereupon @var{size} should be 6). Then if @var{start}
-is 2, @code{re_match} returns 3, i.e., @samp{a*} would have matched the
-last three @samp{a}s in @var{string}. If @var{start} is 0,
-@code{re_match} returns 5, i.e., @samp{a*} would have matched all the
-@samp{a}s in @var{string}. If @var{start} is either 5 or 6, it returns
-zero.
-
-If @var{start} is not between zero and @var{size}, then
-@code{re_match} returns @math{-1}.

-@subsection GNU Searching
-
-@cindex searching with GNU functions
-
-@dfn{Searching} means trying to match starting at successive positions
-within a string. The function @code{re_search} does this.
-
-Before calling @code{re_search}, you must compile your regular
-expression. @xref{GNU Regular Expression Compiling}.
-
-Here is the function declaration:
-
-@findex re_search
-@example
-int
-re_search (struct re_pattern_buffer *@var{pattern_buffer},
- const char *@var{string}, const int @var{size},
- const int @var{start}, const int @var{range},
- struct re_registers *@var{regs})
-@end example
-
-@noindent
-@vindex start @r{argument to @code{re_search}}
-@vindex range @r{argument to @code{re_search}}
-whose arguments are the same as those to @code{re_match} (@pxref{GNU
-Matching}) except that the two arguments @var{start} and @var{range}
-replace @code{re_match}'s argument @var{start}.
-
-If @var{range} is positive, then @code{re_search} attempts a match
-starting first at index @var{start}, then at @math{@var{start} + 1} if
-that fails, and so on, up to @math{@var{start} + @var{range}}; if
-@var{range} is negative, then it attempts a match starting first at
-index @var{start}, then at @math{@var{start} -1} if that fails, and so
-on.
-
-If @var{start} is not between zero and @var{size}, then @code{re_search}
-returns @math{-1}. When @var{range} is positive, @code{re_search}
-adjusts @var{range} so that @math{@var{start} + @var{range} - 1} is
-between zero and @var{size}, if necessary; that way it won't search
-outside of @var{string}. Similarly, when @var{range} is negative,
-@code{re_search} adjusts @var{range} so that @math{@var{start} +
-@var{range} + 1} is between zero and @var{size}, if necessary.
-
-If the @code{fastmap} field of @var{pattern_buffer} is zero,
-@code{re_search} matches starting at consecutive positions; otherwise,
-it uses @code{fastmap} to make the search more efficient.
-@xref{Searching with Fastmaps}.
-
-If no match is found, @code{re_search} returns @math{-1}. If
-a match is found, it returns the index where the match began. If an
-internal error happens, it returns @math{-2}.

- const int @var{start},
- struct re_registers *@var{regs},
- const int @var{stop})
-@end example
-
-@noindent
-is similar to @code{re_match} (@pxref{GNU Matching}) except that you
-pass @emph{two} data strings and sizes, and an index @var{stop} beyond
-which you don't want the matcher to try matching. As with
-@code{re_match}, if it succeeds, @code{re_match_2} returns how many
-characters of @var{string} it matched. Regard @var{string1} and
-@var{string2} as concatenated when you set the arguments @var{start} and
-@var{stop} and use the contents of @var{regs}; @code{re_match_2} never
-returns a value larger than @math{@var{size1} + @var{size2}}.
-
-The function:

-@findex re_search_2
-@example
-int
-re_search_2 (struct re_pattern_buffer *@var{buffer},

- const int @var{start}, const int @var{range},
- struct re_registers *@var{regs},

-
-@node Searching with Fastmaps, GNU Translate Tables, Matching/Searching with Split Data, GNU Regex Functions
-@subsection Searching with Fastmaps
-
-@cindex fastmaps
-If you're searching through a long string, you should use a fastmap.
-Without one, the searcher tries to match at consecutive positions in the
-string. Generally, most of the characters in the string could not start
-a match. It takes much longer to try matching at a given position in the
-string than it does to check in a table whether or not the character at
-that position could start a match. A @dfn{fastmap} is such a table.
-
-More specifically, a fastmap is an array indexed by the characters in
-your character set. Under the @sc{ascii} encoding, therefore, a fastmap
-has 256 elements. If you want the searcher to use a fastmap with a
-given pattern buffer, you must allocate the array and assign the array's
-address to the pattern buffer's @code{fastmap} field. You either can
-compile the fastmap yourself or have @code{re_search} do it for you;
-when @code{fastmap} is nonzero, it automatically compiles a fastmap the
-first time you search using a particular compiled pattern.
-
-To compile a fastmap yourself, use:
-
-@findex re_compile_fastmap
-@example
-int
-re_compile_fastmap (struct re_pattern_buffer *@var{pattern_buffer})
-@end example
-
-@noindent
-@var{pattern_buffer} is the address of a pattern buffer. If the
-character @var{c} could start a match for the pattern,
-@code{re_compile_fastmap} makes
-@code{@var{pattern_buffer}->fastmap[@var{c}]} nonzero. It returns
-@math{0} if it can compile a fastmap and @math{-2} if there is an
-internal error. For example, if @samp{|} is the alternation operator
-and @var{pattern_buffer} holds the compiled pattern for @samp{a|b}, then
-@code{re_compile_fastmap} sets @code{fastmap['a']} and
-@code{fastmap['b']} (and no others).
-
-@code{re_search} uses a fastmap as it moves along in the string: it
-checks the string's characters until it finds one that's in the fastmap.
-Then it tries matching at that character. If the match fails, it
-repeats the process. So, by using a fastmap, @code{re_search} doesn't
-waste time trying to match at positions in the string that couldn't
-start a match.
-
-If you don't want @code{re_search} to use a fastmap,
-store zero in the @code{fastmap} field of the pattern buffer before
-calling @code{re_search}.
-
-Once you've initialized a pattern buffer's @code{fastmap} field, you
-need never do so again---even if you compile a new pattern in
-it---provided the way the field is set still reflects whether or not you
-want a fastmap. @code{re_search} will still either do nothing if
-@code{fastmap} is null or, if it isn't, compile a new fastmap for the
-new pattern.
-
-@node GNU Translate Tables, Using Registers, Searching with Fastmaps, GNU Regex Functions
-@subsection GNU Translate Tables
-
-If you set the @code{translate} field of a pattern buffer to a translate
-table, then the @sc{gnu} Regex functions to which you've passed that
-pattern buffer use it to apply a simple transformation
-to all the regular expression and string characters at which they look.
-
-A @dfn{translate table} is an array indexed by the characters in your
-character set. Under the @sc{ascii} encoding, therefore, a translate
-table has 256 elements. The array's elements are also characters in
-your character set. When the Regex functions see a character @var{c},
-they use @code{translate[@var{c}]} in its place, with one exception: the
-character after a @samp{\} is not translated. (This ensures that, the
-operators, e.g., @samp{\B} and @samp{\b}, are always distinguishable.)
-
-For example, a table that maps all lowercase letters to the
-corresponding uppercase ones would cause the matcher to ignore
-differences in case.@footnote{A table that maps all uppercase letters to
-the corresponding lowercase ones would work just as well for this
-purpose.} Such a table would map all characters except lowercase letters
-to themselves, and lowercase letters to the corresponding uppercase
-ones. Under the @sc{ascii} encoding, here's how you could initialize
-such a table (we'll call it @code{case_fold}):
-
-@example
-for (i = 0; i < 256; i++)
- case_fold[i] = i;
-for (i = 'a'; i <= 'z'; i++)
- case_fold[i] = i - ('a' - 'A');
-@end example
-
-You tell Regex to use a translate table on a given pattern buffer by
-assigning that table's address to the @code{translate} field of that
-buffer. If you don't want Regex to do any translation, put zero into
-this field. You'll get weird results if you change the table's contents
-anytime between compiling the pattern buffer, compiling its fastmap, and
-matching or searching with the pattern buffer.
-
-@node Using Registers, Freeing GNU Pattern Buffers, GNU Translate Tables, GNU Regex Functions
-@subsection Using Registers
-
-A group in a regular expression can match a (posssibly empty) substring
-of the string that regular expression as a whole matched. The matcher
-remembers the beginning and end of the substring matched by
-each group.
-
-To find out what they matched, pass a nonzero @var{regs} argument to a
-@sc{gnu} matching or searching function (@pxref{GNU Matching} and
-@ref{GNU Searching}), i.e., the address of a structure of this type, as
-defined in @file{regex.h}:
-
-@c We don't bother to include this directly from regex.h,
-@c since it changes so rarely.
-@example
-@tindex re_registers
-@vindex num_regs @r{in @code{struct re_registers}}
-@vindex start @r{in @code{struct re_registers}}
-@vindex end @r{in @code{struct re_registers}}
-struct re_registers
-@{
- unsigned num_regs;
- regoff_t *start;
- regoff_t *end;
-@};
-@end example
-
-Except for (possibly) the @var{num_regs}'th element (see below), the
-@var{i}th element of the @code{start} and @code{end} arrays records
-information about the @var{i}th group in the pattern. (They're declared
-as C pointers, but this is only because not all C compilers accept
-zero-length arrays; conceptually, it is simplest to think of them as
-arrays.)
-
-The @code{start} and @code{end} arrays are allocated in various ways,
-depending on the value of the @code{regs_allocated}
-@vindex regs_allocated
-field in the pattern buffer passed to the matcher.
-
-The simplest and perhaps most useful is to let the matcher (re)allocate
-enough space to record information for all the groups in the regular
-expression. If @code{regs_allocated} is @code{REGS_UNALLOCATED},
-@vindex REGS_UNALLOCATED
-the matcher allocates @math{1 + @var{re_nsub}} (another field in the
-pattern buffer; @pxref{GNU Pattern Buffers}). The extra element is set
-to @math{-1}, and sets @code{regs_allocated} to @code{REGS_REALLOCATE}.
-@vindex REGS_REALLOCATE
-Then on subsequent calls with the same pattern buffer and @var{regs}
-arguments, the matcher reallocates more space if necessary.
-
-It would perhaps be more logical to make the @code{regs_allocated} field
-part of the @code{re_registers} structure, instead of part of the
-pattern buffer. But in that case the caller would be forced to
-initialize the structure before passing it. Much existing code doesn't
-do this initialization, and it's arguably better to avoid it anyway.
-
-@code{re_compile_pattern} sets @code{regs_allocated} to
-@code{REGS_UNALLOCATED},
-so if you use the GNU regular expression
-functions, you get this behavior by default.
-
-xx document re_set_registers
-
-@sc{posix}, on the other hand, requires a different interface: the
-caller is supposed to pass in a fixed-length array which the matcher
-fills. Therefore, if @code{regs_allocated} is @code{REGS_FIXED}
-@vindex REGS_FIXED
-the matcher simply fills that array.
-
-The following examples illustrate the information recorded in the
-@code{re_registers} structure. (In all of them, @samp{(} represents the
-open-group and @samp{)} the close-group operator. The first character
-in the string @var{string} is at index 0.)
-
-@c xx i'm not sure this is all true anymore.
-
-@itemize @bullet
-
-@item
-If the regular expression has an @w{@var{i}-th}
-group not contained within another group that matches a
-substring of @var{string}, then the function sets
-@code{@w{@var{regs}->}start[@var{i}]} to the index in @var{string} where
-the substring matched by the @w{@var{i}-th} group begins, and
-@code{@w{@var{regs}->}end[@var{i}]} to the index just beyond that
-substring's end. The function sets @code{@w{@var{regs}->}start[0]} and
-@code{@w{@var{regs}->}end[0]} to analogous information about the entire
-pattern.
-
-For example, when you match @samp{((a)(b))} against @samp{ab}, you get:
-
-@itemize
-@item
-0 in @code{@w{@var{regs}->}start[0]} and 2 in @code{@w{@var{regs}->}end[0]}

-@end itemize
-
-@item
-If a group matches more than once (as it might if followed by,
-e.g., a repetition operator), then the function reports the information
-about what the group @emph{last} matched.
-
-For example, when you match the pattern @samp{(a)*} against the string
-@samp{aa}, you get:
-
-@itemize
-@item
-0 in @code{@w{@var{regs}->}start[0]} and 2 in @code{@w{@var{regs}->}end[0]}
-
-@item
-1 in @code{@w{@var{regs}->}start[1]} and 2 in @code{@w{@var{regs}->}end[1]}
-@end itemize
-
-@item
-If the @w{@var{i}-th} group does not participate in a
-successful match, e.g., it is an alternative not taken or a
-repetition operator allows zero repetitions of it, then the function
-sets @code{@w{@var{regs}->}start[@var{i}]} and
-@code{@w{@var{regs}->}end[@var{i}]} to @math{-1}.
-
-For example, when you match the pattern @samp{(a)*b} against
-the string @samp{b}, you get:
-
-@itemize
-@item
-0 in @code{@w{@var{regs}->}start[0]} and 1 in @code{@w{@var{regs}->}end[0]}
-
-@item
-@math{-1} in @code{@w{@var{regs}->}start[1]} and @math{-1} in @code{@w{@var{regs}->}end[1]}
-@end itemize
-
-@item
-If the @w{@var{i}-th} group matches a zero-length string, then the
-function sets @code{@w{@var{regs}->}start[@var{i}]} and
-@code{@w{@var{regs}->}end[@var{i}]} to the index just beyond that
-zero-length string.
-
-For example, when you match the pattern @samp{(a*)b} against the string
-@samp{b}, you get:
-
-@itemize
-@item
-0 in @code{@w{@var{regs}->}start[0]} and 1 in @code{@w{@var{regs}->}end[0]}
-
-@item
-0 in @code{@w{@var{regs}->}start[1]} and 0 in @code{@w{@var{regs}->}end[1]}
-@end itemize
-
-@ignore
-The function sets @code{@w{@var{regs}->}start[0]} and
-@code{@w{@var{regs}->}end[0]} to analogous information about the entire

-
-For example, when you match the pattern @samp{(a*)} against the empty
-string, you get:
-
-@itemize
-@item
-0 in @code{@w{@var{regs}->}start[0]} and 0 in @code{@w{@var{regs}->}end[0]}
-

-
-@item
-If an @w{@var{i}-th} group contains a @w{@var{j}-th} group
-in turn not contained within any other group within group @var{i} and

-@code{@w{@var{regs}->}end[@var{j}]} the last match (if it matched) of
-the @w{@var{j}-th} group.
-
-For example, when you match the pattern @samp{((a*)b)*} against the

-

-@item

-@subsection POSIX Regular Expression Compiling
-
-With @sc{posix}, you can only search for a given regular expression; you
-can't match it. To do this, you must first compile it in a
-pattern buffer, using @code{regcomp}.
-
-@ignore
-Before calling @code{regcomp}, you must initialize this pattern buffer
-as you do for @sc{gnu} (@pxref{GNU Regular Expression Compiling}). See
-below, however, for how to choose a syntax with which to compile.
-@end ignore
-
-To compile a pattern buffer, use:
-
-@findex regcomp
-@example
-int
-regcomp (regex_t *@var{preg}, const char *@var{regex}, int @var{cflags})
-@end example
-
-@noindent
-@var{preg} is the initialized pattern buffer's address, @var{regex} is
-the regular expression's address, and @var{cflags} is the compilation
-flags, which Regex considers as a collection of bits. Here are the
-valid bits, as defined in @file{regex.h}:

-@node POSIX Matching, Reporting Errors, POSIX Regular Expression Compiling, POSIX Regex Functions
-@subsection POSIX Matching
-
-Matching the @sc{posix} way means trying to match a null-terminated
-string starting at its first character. Once you've compiled a pattern
-into a pattern buffer (@pxref{POSIX Regular Expression Compiling}), you
-can ask the matcher to match that pattern against a string using:
-
-@findex regexec
-@example
-int
-regexec (const regex_t *@var{preg}, const char *@var{string},
- size_t @var{nmatch}, regmatch_t @var{pmatch}[], int @var{eflags})
-@end example
-
-@noindent
-@var{preg} is the address of a pattern buffer for a compiled pattern.
-@var{string} is the string you want to match.
-
-@xref{Using Byte Offsets}, for an explanation of @var{pmatch}. If you
-pass zero for @var{nmatch} or you compiled @var{preg} with the
-compilation flag @code{REG_NOSUB} set, then @code{regexec} will ignore
-@var{pmatch}; otherwise, you must allocate it to have at least
-@var{nmatch} elements. @code{regexec} will record @var{nmatch} byte
-offsets in @var{pmatch}, and set to @math{-1} any unused elements up to
-@math{@var{pmatch}@code{[@var{nmatch}]} - 1}.
-
-@var{eflags} specifies @dfn{execution flags}---namely, the two bits
-@code{REG_NOTBOL} and @code{REG_NOTEOL} (defined in @file{regex.h}). If
-you set @code{REG_NOTBOL}, then the match-beginning-of-line operator
-(@pxref{Match-beginning-of-line Operator}) always fails to match.
-This lets you match against pieces of a line, as you would need to if,
-say, searching for repeated instances of a given pattern in a line; it
-would work correctly for patterns both with and without
-match-beginning-of-line operators. @code{REG_NOTEOL} works analogously
-for the match-end-of-line operator (@pxref{Match-end-of-line
-Operator}); it exists for symmetry.
-
-@code{regexec} tries to find a match for @var{preg} in @var{string}
-according to the syntax in @var{preg}'s @code{syntax} field.
-(@xref{POSIX Regular Expression Compiling}, for how to set it.) The
-function returns zero if the compiled pattern matches @var{string} and
-@code{REG_NOMATCH} (defined in @file{regex.h}) if it doesn't.
-
-@node Reporting Errors, Using Byte Offsets, POSIX Matching, POSIX Regex Functions
-@subsection Reporting Errors
-
-If either @code{regcomp} or @code{regexec} fail, they return a nonzero
-error code, the possibilities for which are defined in @file{regex.h}.
-@xref{POSIX Regular Expression Compiling}, and @ref{POSIX Matching}, for
-what these codes mean. To get an error string corresponding to these
-codes, you can use:
-
-@findex regerror
-@example
-size_t
-regerror (int @var{errcode},
- const regex_t *@var{preg},
- char *@var{errbuf},
- size_t @var{errbuf_size})
-@end example
-
-@noindent
-@var{errcode} is an error code, @var{preg} is the address of the pattern
-buffer which provoked the error, @var{errbuf} is the error buffer, and
-@var{errbuf_size} is @var{errbuf}'s size.
-
-@code{regerror} returns the size in bytes of the error string
-corresponding to @var{errcode} (including its terminating null). If
-@var{errbuf} and @var{errbuf_size} are nonzero, it also returns in
-@var{errbuf} the first @math{@var{errbuf_size} - 1} characters of the
-error string, followed by a null.
-@var{errbuf_size} must be a nonnegative number less than or equal to the
-size in bytes of @var{errbuf}.
-
-You can call @code{regerror} with a null @var{errbuf} and a zero
-@var{errbuf_size} to determine how large @var{errbuf} need be to
-accommodate @code{regerror}'s error string.
-
-@node Using Byte Offsets, Freeing POSIX Pattern Buffers, Reporting Errors, POSIX Regex Functions
-@subsection Using Byte Offsets
-
-In @sc{posix}, variables of type @code{regmatch_t} hold analogous
-information, but are not identical to, @sc{gnu}'s registers (@pxref{Using
-Registers}). To get information about registers in @sc{posix}, pass to
-@code{regexec} a nonzero @var{pmatch} of type @code{regmatch_t}, i.e.,
-the address of a structure of this type, defined in
-@file{regex.h}:
-
-@tindex regmatch_t
-@example
-typedef struct
-@{
- regoff_t rm_so;
- regoff_t rm_eo;
-@} regmatch_t;
-@end example
-
-When reading in @ref{Using Registers}, about how the matching function
-stores the information into the registers, substitute @var{pmatch} for
-@var{regs}, @code{@w{@var{pmatch}[@var{i}]->}rm_so} for
-@code{@w{@var{regs}->}start[@var{i}]} and
-@code{@w{@var{pmatch}[@var{i}]->}rm_eo} for

-syntax (@pxref{Regular Expression Syntax}).
-
-To compile a regular expression use:
-
-@findex re_comp

-char *
-re_comp (char *@var{regex})
-@end example
-
-@noindent
-@var{regex} is the address of a null-terminated regular expression.
-@code{re_comp} uses an internal pattern buffer, so you can use only the
-most recently compiled pattern buffer. This means that if you want to
-use a given regular expression that you've already compiled---but it
-isn't the latest one you've compiled---you'll have to recompile it. If
-you call @code{re_comp} with the null string (@emph{not} the empty

-buffer.
-
-If @code{re_comp} successfully compiles the regular expression, it

-@unnumberedsec Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software---to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.

-@enumerate
-@item
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-@item
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-@item
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-@enumerate a
-@item
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-@item
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-@item
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-@end enumerate
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-@item
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-@enumerate a
-@item
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-@item
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-@item
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-@end enumerate
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-@item
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-@item
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-@item
-If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-@item
-If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding

-countries not thus excluded. In such case, this License incorporates

-@item
-The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and ``any
-later version'', you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-@item
-If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.

-@unnumberedsec Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the ``copyright'' line and a pointer to where the full notice is found.
-
-@smallexample
-@var{one line to give the program's name and a brief idea of what it does.}
-Copyright (C) 19@var{yy} @var{name of author}
-
-This program is free software; you can redistribute it and/or modify
-it under the terms of the GNU General Public License as published by
-the Free Software Foundation; either version 2 of the License, or
-(at your option) any later version.
-
-This program is distributed in the hope that it will be useful,
-but WITHOUT ANY WARRANTY; without even the implied warranty of
-MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
-GNU General Public License for more details.
-
-You should have received a copy of the GNU General Public License
-along with this program; if not, write to the Free Software
-Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-@end smallexample
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-@smallexample
-Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
-Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-This is free software, and you are welcome to redistribute it
-under certain conditions; type `show c' for details.
-@end smallexample
-
-The hypothetical commands @samp{show w} and @samp{show c} should show
-the appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than @samp{show w} and
-@samp{show c}; they could even be mouse-clicks or menu items---whatever
-suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a ``copyright disclaimer'' for the program, if
-necessary. Here is a sample; alter the names:
-
-@example
-Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-`Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-@var{signature of Ty Coon}, 1 April 1989
-Ty Coon, President of Vice
-@end example
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-This is the beta-test version of the GNU assembler. (Probably
-around Version 1.35, but check version.c which gets updated more
-often than this readme.)
-
-The assembler has been modified to support a feature that is
-potentially useful when assembling compiler output, but which may
-confuse assembly language programmers. If assembler encounters a
-.word pseudo-op of the form symbol1-symbol2 (the difference of two
-symbols), and the difference of those two symbols will not fit in 16
-bits, the assembler will create a branch around a long jump to
-symbol1, and insert this into the output directly before the next
-label: The .word will (instead of containing garbage, or giving an
-error message) contain (the address of the long jump)-symbol2. This
-allows the assembler to assemble jump tables that jump to locations
-very far away into code that works properly. If the next label is
-more than 32K away from the .word, you lose (silently) RMS claims
-this will never happen. If the -k option is given, you will get a
-warning message when this happens.
-
-These files are currently set up to allow you to compile all of the
-versions of the assembler (68020, VAX, ns32k, and i386) on the same
-machine. To compile the 68020 version, type 'make a68'. To compile
-the VAX version, type 'make avax'. To compile the ns32k version,
-type 'make a32k'. To compile the Intel 80386 version, type 'make
-a386'. The Makefile contains instructions on how to make one of the
-assemblers compile as the default.
-
-Before you can compile the 68020 version of the assembler, you must
-make m68k.h be a link to m-sun3.h , m-hpux.h or m-generic.h . If
-you are on a SUN-3 (or other machine that uses a magic number of
-(2 << 16) | OMAGIC type 'ln -s m-sun3.h m68k.h' else if you are on a
-machine running HP-UX, type 'ln m-hpux.h m689k.h' else type
-'ln -s m-generic.h m68k.h' If your machine does not support symbolic
-links, omit the '-s'.
-
-See the instructions in the Makefile for compiling gas for the Sequent
-Symmetry (dynix 3.0.12 + others?) or for the HP 9000/300
-
-If your machine does not have both varargs.h and vfprintf(), but does have
-_doprnt() add -DNO_VARARGS to the CFLAGS line in the makefile. If your
-machine has neither vfprintf() or _doprnt(), you will have to change
-messages.c in order to get readable error messages from the assembler.
-
-
- REPORTING BUGS IN GAS
-
-Bugs in gas should be reported to bug-gnu-utils@prep.ai.mit.edu If you can't
-get through to prep, try hack@gnu.ai.mit.edu or hack@media-lab.media.mit.edu
-
-If you report a bug in GAS, please remember to include:
-
-A description of exactly what went wrong.
-
-The type of machine GAS was running on (VAX, 68020, etc),
-
-The Operating System GAS was running under.
-
-The options given to GAS.
-
-The actual input file that caused the problem.
-
-It is silly to report a bug in GAS without including an input file for
-GAS. Don't ask us to generate the file just because you made it from
-files you think we have access to.
-
-1. You might be mistaken.
-2. It might take us a lot of time to install things to regenerate that file.
-3. We might get a different file from the one you got, and might not see any
-bug.
-
-To save us these delays and uncertainties, always send the input file
-for the program that failed.
-
-If the input file is very large, and you are on the internet, you may
-want to make it avaliable for anonymous FTP instead of mailing it. If you
-do, include instructions for FTP'ing it in your bug report.
-
------------------------------- README.APOLLO ---------------------------------
-
-The changes required to get the GNU C compiler running on
-Apollo 68K platforms are available via anonymous ftp from
-labrea.stanford.edu (36.8.0.47) in the form of a compressed
-tar file named "/pub/gnu/apollo-gcc-1.37.tar.Z".
-The size of the file is 84145 bytes.
-
-To build GCC for the Apollo you'll need the virgin FSF
-distributions of bison-1.03, gas-1.34, and gcc-1.37. They
-are also on labrea.stanford.edu as well as prep.ai.mit.edu.
-My changes are to enable gas to produce Apollo COFF object
-files and allow gcc to parse some of the syntax extensions
-which appear in Apollo C header files. Note that the
-COFF encapsulation technique cannot be used on the Apollo.
-
-The tar file should be unpacked in the directory containing
-the gas-1.34 and gcc-1.37 directories; a few files will be overlaid,
-and an APOLLO-GCC-README file will appear in the top directory.
-This file contains detailed instructions on how to proceed.
-
-These changes will only work for SR10.1 or later systems, using
-the 6.6 or later version of the Apollo C compiler.
-
-If you do not have ftp access, I can mail you the changes in the
-form of diffs; they are approximately 40K in length. If you request
-them, be sure to give me a voice phone number so I can contact you
-in case I can't send you mail; I've had several requests in the
-past from people I can't contact.
-
-By the way, I'm working on getting the GNU C++ compiler running;
-there are a couple problems to solve. I hope to be able to announce
-the Apollo version shortly after the 1.37 version is released.

-These contain patches for gas that will make it produce COFF output.
-I have never seen these patches, so I don't know how well they work.

-@cindex manual, structure and purpose
-This manual is intended to describe what you need to know to use
-@sc{gnu} @code{_AS__}. We cover the syntax expected in source files, including
-notation for symbols, constants, and expressions; the directives that
-@code{_AS__} understands; and of course how to invoke @code{_AS__}.
-
-_if__(!_GENERIC__)
-We also cover special features in the _HOST__
-configuration of @code{_AS__}, including assembler directives.
-_fi__(!_GENERIC__)
-_if__(_GENERIC__)
-This manual also describes some of the machine-dependent features of
-various flavors of the assembler.
-_fi__(_GENERIC__)
-_if__(_INTERNALS__)
-This manual also describes how the assembler works internally, and
-provides some information that may be useful to people attempting to
-port the assembler to another machine.
-_fi__(_INTERNALS__)
-@refill
-
-@cindex machine instructions (not covered)
-On the other hand, this manual is @emph{not} intended as an introduction
-to programming in assembly language---let alone programming in general!
-In a similar vein, we make no attempt to introduce the machine
-architecture; we do @emph{not} describe the instruction set, standard
-mnemonics, registers or addressing modes that are standard to a
-particular architecture.
-_if__(_GENERIC__)
-You may want to consult the manufacturer's
-machine architecture manual for this information.
-_fi__(_GENERIC__)
-_if__(_H8__&&!_GENERIC__)
-For information on the H8/300 machine instruction set, see @cite{H8/300
-Series Programming Manual} (Hitachi ADE--602--025).
-_fi__(_H8__&&!_GENERIC__)
-
-
-@c I think this is premature---pesch@cygnus.com, 17jan1991
-@ignore
-Throughout this manual, we assume that you are running @dfn{GNU},
-the portable operating system from the @dfn{Free Software
-Foundation, Inc.}. This restricts our attention to certain kinds of
-computer (in particular, the kinds of computers that GNU can run on);
-once this assumption is granted examples and definitions need less
-qualification.
-
-@code{_AS__} is part of a team of programs that turn a high-level
-human-readable series of instructions into a low-level
-computer-readable series of instructions. Different versions of
-@code{_AS__} are used for different kinds of computer.
-@end ignore
-
-@c There used to be a section "Terminology" here, which defined
-@c "contents", "byte", "word", and "long". Defining "word" to any
-@c particular size is confusing when the .word directive may generate 16
-@c bits on one machine and 32 bits on another; in general, for the user
-@c version of this manual, none of these terms seem essential to define.
-@c They were used very little even in the former draft of the manual;
-@c this draft makes an effort to avoid them (except in names of
-@c directives).
-
-@node GNU Assembler, Object Formats, Manual, Overview
-@section _AS__, the GNU Assembler
-
-GNU @code{as} is really a family of assemblers.
-_if__(!_GENERIC__)
-This manual describes @code{_AS__}, a member of that family which is
-configured for the _HOST__ architectures.
-_fi__(!_GENERIC__)
-If you use (or have used) the GNU assembler on one architecture, you
-should find a fairly similar environment when you use it on another
-architecture. Each version has much in common with the others,
-including object file formats, most assembler directives (often called
-@dfn{pseudo-ops)} and assembler syntax.@refill
-
-_if__(_GENERIC__||!_H8__)
-@cindex purpose of @sc{gnu} @code{_AS__}
-@code{_AS__} is primarily intended to assemble the output of the GNU C
-compiler @code{_GCC__} for use by the linker @code{_LD__}. Nevertheless,
-we've tried to make @code{_AS__} assemble correctly everything that the native
-assembler would.
-_fi__(_GENERIC__||!_H8__)
-_if__(_VAX__)
-Any exceptions are documented explicitly (@pxref{_MACH_DEP__}).
-_fi__(_VAX__)
-_if__(_GENERIC__||_M680X0__)
-This doesn't mean @code{_AS__} always uses the same syntax as another
-assembler for the same architecture; for example, we know of several
-incompatible versions of 680x0 assembly language syntax.
-_fi__(_GENERIC__||_M680X0__)
-
-Unlike older assemblers, @code{_AS__} is designed to assemble a source
-program in one pass of the source file. This has a subtle impact on the
-@kbd{.org} directive (@pxref{Org,,@code{.org}}).
-
-@node Object Formats, Command Line, GNU Assembler, Overview
-@section Object File Formats
-

-@section Command Line
-
-@cindex command line conventions
-After the program name @code{_AS__}, the command line may contain
-options and file names. Options may appear in any order, and may be
-before, after, or between file names. The order of file names is
-significant.
-
-@cindex standard input, as input file
-@kindex --
-@file{--} (two hyphens) by itself names the standard input file
-explicitly, as one of the files for @code{_AS__} to assemble.
-
-@cindex options, command line
-Except for @samp{--} any command line argument that begins with a
-hyphen (@samp{-}) is an option. Each option changes the behavior of
-@code{_AS__}. No option changes the way another option works. An
-option is a @samp{-} followed by one or more letters; the case of
-the letter is important. All options are optional.
-
-Some options expect exactly one file name to follow them. The file
-name may either immediately follow the option's letter (compatible
-with older assemblers) or it may be the next command argument (GNU
-standard). These two command lines are equivalent:
-
-@smallexample
-_AS__ -o my-object-file.o mumble.s
-_AS__ -omy-object-file.o mumble.s

-@section Input Files
-
-@cindex input
-@cindex source program
-@cindex files, input
-We use the phrase @dfn{source program}, abbreviated @dfn{source}, to
-describe the program input to one run of @code{_AS__}. The program may
-be in one or more files; how the source is partitioned into files
-doesn't change the meaning of the source.
-
-@c I added "con" prefix to "catenation" just to prove I can overcome my
-@c APL training... pesch@cygnus.com
-The source program is a concatenation of the text in all the files, in the
-order specified.
-
-Each time you run @code{_AS__} it assembles exactly one source
-program. The source program is made up of one or more files.
-(The standard input is also a file.)
-
-You give @code{_AS__} a command line that has zero or more input file
-names. The input files are read (from left file name to right). A
-command line argument (in any position) that has no special meaning
-is taken to be an input file name.
-
-If you give @code{_AS__} no file names it attempts to read one input file
-from the @code{_AS__} standard input, which is normally your terminal. You
-may have to type @key{ctl-D} to tell @code{_AS__} there is no more program
-to assemble.
-
-Use @samp{--} if you need to explicitly name the standard input file
-in your command line.
-
-If the source is empty, @code{_AS__} will produce a small, empty object
-file.

-
-@cindex input file linenumbers
-@cindex line numbers, in input files
-There are two ways of locating a line in the input file (or files) and
-either may be used in reporting error messages. One way refers to a line
-number in a physical file; the other refers to a line number in a
-``logical'' file. @xref{Errors, ,Error and Warning Messages}.
-
-@dfn{Physical files} are those files named in the command line given
-to @code{_AS__}.
-
-@dfn{Logical files} are simply names declared explicitly by assembler
-directives; they bear no relation to physical files. Logical file names
-help error messages reflect the original source file, when @code{_AS__}
-source is itself synthesized from other files.

-@cindex object file
-@cindex output file
-@kindex a.out
-@kindex .o
-Every time you run @code{_AS__} it produces an output file, which is
-your assembly language program translated into numbers. This file
-is the object file, named @code{a.out} unless you tell @code{_AS__} to
-give it another name by using the @code{-o} option. Conventionally,

-@cindex warning messages
-@cindex messages from @code{_AS__}
-@code{_AS__} may write warnings and error messages to the standard error
-file (usually your terminal). This should not happen when a compiler
-runs @code{_AS__} automatically. Warnings report an assumption made so
-that @code{_AS__} could keep assembling a flawed program; errors report a
-grave problem that stops the assembly.
-

-
-@kindex -a
-@kindex -al
-@kindex -as
-@cindex listings, enabling
-@cindex assembly listings, enabling
-These options enable listing output from the assembler. @samp{-a} by
-itself requests all listing output; @samp{-al} requests only the
-output-program listing, and @samp{-as} requests only a symbol table
-listing.
-
-Once you have specified one of these options, you can further control
-listing output and its appearance using the directives @code{.list},
-@code{.nolist}, @code{.psize}, @code{.eject}, @code{.title}, and
-@code{.sbttl}.
-
-If you do not request listing output with one of the @samp{-a} options, the
-listing-control directives have no effect.
-

-Use this option to add a @var{path} to the list of directories
-@code{_AS__} will search for files specified in @code{.include}
-directives (@pxref{Include,,@code{.include}}). You may use @code{-I} as

-_if__((!_GENERIC__) && (!_DIFFTABKLUG__))
-On the _HOST__ family, this option is allowed, but has no effect. It is
-permitted for compatibility with the GNU assembler on other platforms,
-where it can be used to warn when the assembler alters the machine code
-generated for @samp{.word} directives in difference tables. The _HOST__

-@cindex local labels, retaining in output
-Labels beginning with @samp{L} (upper case only) are called @dfn{local
-labels}. @xref{Symbol Names}. Normally you don't see such labels when
-debugging, because they are intended for the use of programs (like
-compilers) that compose assembler programs, not for your notice.
-Normally both @code{_AS__} and @code{_LD__} discard such labels, so you don't
-normally debug with them.
-
-This option tells @code{_AS__} to retain those @samp{L@dots{}} symbols
-in the object file. Usually if you do this you also tell the linker
-@code{_LD__} to preserve symbols whose names begin with @samp{L}.
-
-@section Name the Object File: @code{-o}
-
-@kindex -o
-@cindex naming object file
-@cindex object file name
-There is always one object file output when you run @code{_AS__}. By
-default it has the name @file{a.out}. You use this option (which
-takes exactly one filename) to give the object file a different name.
-
-Whatever the object file is called, @code{_AS__} will overwrite any
-existing file of the same name.
-
-@section Join Data and Text Sections: @code{-R}
-
-@kindex -R
-@cindex data and text sections, joining
-@cindex text and data sections, joining
-@cindex joining text and data sections
-@cindex merging text and data sections
-@code{-R} tells @code{_AS__} to write the object file as if all
-data-section data lives in the text section. This is only done at
-the very last moment: your binary data are the same, but data
-section parts are relocated differently. The data section part of
-your object file is zero bytes long because all it bytes are
-appended to the text section. (@xref{Sections,,Sections and Relocation}.)
-
-When you specify @code{-R} it would be possible to generate shorter
-address displacements (because we don't have to cross between text and
-data section). We refrain from doing this simply for compatibility with
-older versions of @code{_AS__}. In future, @code{-R} may work this way.
-
-_if__(_COFF__)
-When @code{_AS__} is configured for COFF output,
-this option is only useful if you use sections named @samp{.text} and
-@samp{.data}.
-_fi__(_COFF__)
-
-@section Announce Version: @code{-v}
-
-@kindex -v
-@kindex -version
-@cindex @code{_AS__} version
-@cindex version of @code{_AS__}
-You can find out what version of as is running by including the
-option @samp{-v} (which you can also spell as @samp{-version}) on the
-command line.
-
-@section Suppress Warnings: @code{-W}
-
-@kindex -W
-@cindex suppressing warnings
-@cindex warnings, suppressing
-@code{_AS__} should never give a warning or error message when
-assembling compiler output. But programs written by people often
-cause @code{_AS__} to give a warning that a particular assumption was
-made. All such warnings are directed to the standard error file.
-If you use this option, no warnings are issued. This option only
-affects the warning messages: it does not change any particular of how
-@code{_AS__} assembles your file. Errors, which stop the assembly, are
-still reported.

-@section Background
-
-Roughly, a section is a range of addresses, with no gaps; all data
-``in'' those addresses is treated the same for some particular purpose.
-For example there may be a ``read only'' section.
-
-@cindex linker, and assembler
-@cindex assembler, and linker
-The linker @code{_LD__} reads many object files (partial programs) and
-combines their contents to form a runnable program. When @code{_AS__}
-emits an object file, the partial program is assumed to start at address
-0. @code{_LD__} will assign the final addresses the partial program
-occupies, so that different partial programs don't overlap. This is
-actually an over-simplification, but it will suffice to explain how
-@code{_AS__} uses sections.
-
-@code{_LD__} moves blocks of bytes of your program to their run-time
-addresses. These blocks slide to their run-time addresses as rigid
-units; their length does not change and neither does the order of bytes
-within them. Such a rigid unit is called a @emph{section}. Assigning
-run-time addresses to sections is called @dfn{relocation}. It includes
-the task of adjusting mentions of object-file addresses so they refer to
-the proper run-time addresses.
-_if__(_H8__)
-For the H8/300, @code{_AS__} pads sections if needed to ensure they end
-on a word (sixteen bit) boundary.
-_fi__(_H8__)
-
-@cindex standard @code{_AS__} sections
-An object file written by @code{_AS__} has at least three sections, any
-of which may be empty. These are named @dfn{text}, @dfn{data} and
-@dfn{bss} sections.
-
-_if__(_COFF__)
-_if__(_GENERIC__)
-When it generates COFF output,
-_fi__(_GENERIC__)
-@code{_AS__} can also generate whatever other named sections you specify
-using the @samp{.section} directive (@pxref{Section,,@code{.section}}).
-If you don't use any directives that place output in the @samp{.text}
-or @samp{.data} sections, these sections will still exist, but will be empty.
-_fi__(_COFF__)
-
-Within the object file, the text section starts at address @code{0}, the
-data section follows, and the bss section follows the data section.
-
-To let @code{_LD__} know which data will change when the sections are
-relocated, and how to change that data, @code{_AS__} also writes to the
-object file details of the relocation needed. To perform relocation
-@code{_LD__} must know, each time an address in the object
-file is mentioned:
-@itemize @bullet
-@item
-Where in the object file is the beginning of this reference to
-an address?
-@item
-How long (in bytes) is this reference?
-@item
-Which section does the address refer to? What is the numeric value of
-@display
-(@var{address}) @minus{} (@var{start-address of section})?
-@end display
-@item
-Is the reference to an address ``Program-Counter relative''?
-@end itemize
-
-@cindex addresses, format of
-@cindex section-relative addressing
-In fact, every address @code{_AS__} ever uses is expressed as
-@display
-(@var{section}) + (@var{offset into section})
-@end display
-@noindent
-Further, every expression @code{_AS__} computes is of this section-relative
-nature. @dfn{Absolute expression} means an expression with section
-``absolute'' (@pxref{_LD__ Sections}). A @dfn{pass1 expression} means
-an expression with section ``pass1'' (@pxref{_AS__ Sections,,_AS__
-Internal Sections}). In this manual we use the notation @{@var{secname}
-@var{N}@} to mean ``offset @var{N} into section @var{secname}''.
-
-Apart from text, data and bss sections you need to know about the
-@dfn{absolute} section. When @code{_LD__} mixes partial programs,
-addresses in the absolute section remain unchanged. For example, address
-@code{@{absolute 0@}} is ``relocated'' to run-time address 0 by @code{_LD__}.
-Although two partial programs' data sections will not overlap addresses
-after linking, @emph{by definition} their absolute sections will overlap.
-Address @code{@{absolute@ 239@}} in one partial program will always be the same
-address when the program is running as address @code{@{absolute@ 239@}} in any
-other partial program.
-
-The idea of sections is extended to the @dfn{undefined} section. Any
-address whose section is unknown at assembly time is by definition
-rendered @{undefined @var{U}@}---where @var{U} will be filled in later.
-Since numbers are always defined, the only way to generate an undefined
-address is to mention an undefined symbol. A reference to a named
-common block would be such a symbol: its value is unknown at assembly
-time so it has section @emph{undefined}.
-
-By analogy the word @emph{section} is used to describe groups of sections in
-the linked program. @code{_LD__} puts all partial programs' text
-sections in contiguous addresses in the linked program. It is
-customary to refer to the @emph{text section} of a program, meaning all
-the addresses of all partial program's text sections. Likewise for
-data and bss sections.
-
-Some sections are manipulated by @code{_LD__}; others are invented for
-use of @code{_AS__} and have no meaning except during assembly.
-
-@node _LD__ Sections, _AS__ Sections, Secs Background, Sections
-@section _LD__ Sections
-@code{_LD__} deals with just four kinds of sections, summarized below.

-These sections hold your program. @code{_AS__} and @code{_LD__} treat them as
-separate but equal sections. Anything you can say of one section is
-true another.
-_if__(_AOUT__||_BOUT__)
-When the program is running, however, it is
-customary for the text section to be unalterable. The
-text section is often shared among processes: it will contain
-instructions, constants and the like. The data section of a running
-program is usually alterable: for example, C variables would be stored
-in the data section.
-_fi__(_AOUT__||_BOUT__)
-
-@cindex bss section
-@item bss section
-This section contains zeroed bytes when your program begins running. It
-is used to hold unitialized variables or common storage. The length of
-each partial program's bss section is important, but because it starts
-out containing zeroed bytes there is no need to store explicit zero
-bytes in the object file. The bss section was invented to eliminate
-those explicit zeros from object files.
-
-@cindex absolute section
-@item absolute section
-Address 0 of this section is always ``relocated'' to runtime address 0.
-This is useful if you want to refer to an address that @code{_LD__} must
-not change when relocating. In this sense we speak of absolute
-addresses being ``unrelocatable'': they don't change during relocation.
-
-@cindex undefined section

-the preceding sections.

-_if__(_GENERIC__)
-(On most machines, you can also use @code{$} in symbol names; exceptions

-
-_if__(_A29K__)
-For the AMD 29K family, @samp{?} is also allowed in the
-body of a symbol name, though not at its beginning.
-_fi__(_A29K__)

-Each symbol has exactly one name. Each name in an assembly language
-program refers to exactly one symbol. You may use that symbol name any
-number of times in a program.

-@cindex local symbol names
-@cindex symbol names, local
-@cindex temporary symbol names
-@cindex symbol names, temporary
-Local symbols help compilers and programmers use names temporarily.
-There are ten local symbol names, which are re-used throughout the
-program. You may refer to them using the names @samp{0} @samp{1}
-@dots{} @samp{9}. To define a local symbol, write a label of the form
-@samp{@b{N}:} (where @b{N} represents any digit). To refer to the most
-recent previous definition of that symbol write @samp{@b{N}b}, using the
-same digit as when you defined the label. To refer to the next
-definition of a local label, write @samp{@b{N}f}---where @b{N} gives you
-a choice of 10 forward references. The @samp{b} stands for
-``backwards'' and the @samp{f} stands for ``forwards''.
-
-Local symbols are not emitted by the current GNU C compiler.
-
-There is no restriction on how you can use these labels, but
-remember that at any point in the assembly you can refer to at most
-10 prior local labels and to at most 10 forward local labels.
-
-Local symbol names are only a notation device. They are immediately
-transformed into more conventional symbol names before the assembler
-uses them. The symbol names stored in the symbol table, appearing in
-error messages and optionally emitted to the object file have these
-parts:
-
-@table @code
-@item L
-All local labels begin with @samp{L}. Normally both @code{_AS__} and
-@code{_LD__} forget symbols that start with @samp{L}. These labels are
-used for symbols you are never intended to see. If you give the
-@samp{-L} option then @code{_AS__} will retain these symbols in the
-object file. If you also instruct @code{_LD__} to retain these symbols,
-you may use them in debugging.
-
-@item @var{digit}
-If the label is written @samp{0:} then the digit is @samp{0}.
-If the label is written @samp{1:} then the digit is @samp{1}.
-And so on up through @samp{9:}.
-
-@item @ctrl{A}
-This unusual character is included so you don't accidentally invent
-a symbol of the same name. The character has ASCII value
-@samp{\001}.
-
-@item @emph{ordinal number}
-This is a serial number to keep the labels distinct. The first
-@samp{0:} gets the number @samp{1}; The 15th @samp{0:} gets the
-number @samp{15}; @emph{etc.}. Likewise for the other labels @samp{1:}
-through @samp{9:}.
-@end table
-
-For instance, the first @code{1:} is named @code{L1@ctrl{A}1}, the 44th
-@code{3:} is named @code{L3@ctrl{A}44}.

-@cindex symbol value
-The value of a symbol is (usually) 32 bits. For a symbol which labels a
-location in the text, data, bss or absolute sections the value is the
-number of addresses from the start of that section to the label.
-Naturally for text, data and bss sections the value of a symbol changes
-as @code{_LD__} changes section base addresses during linking. Absolute
-symbols' values do not change during linking: that is why they are
-called absolute.
-
-The value of an undefined symbol is treated in a special way. If it is
-0 then the symbol is not defined in this assembler source program, and
-@code{_LD__} will try to determine its value from other programs it is
-linked with. You make this kind of symbol simply by mentioning a symbol
-name without defining it. A non-zero value represents a @code{.comm}
-common declaration. The value is how much common storage to reserve, in
-bytes (addresses). The symbol refers to the first address of the
-allocated storage.

-@item @kbd{-V} (Virtualize Interpass Temporary File)
-@cindex @code{-V}, redundant on VAX
-Some other assemblers use a temporary file. This option

-option is redundant.
-
-@item @kbd{-J} (JUMPify Longer Branches)

-Many 32-bit computers permit a variety of branch instructions
-to do the same job. Some of these instructions are short (and

-can branch anywhere in virtual memory. Often there are 3

-this option to emit short and long branches.
-

-@cindex @code{-t}, ignored on VAX
-Some other assemblers may use a temporary file, and this option
-takes a filename being the directory to site the temporary

-
-@cindex i386 syntax compatibility
-@cindex syntax compatibility, i386
-In order to maintain compatibility with the output of @code{_GCC__},
-@code{_AS__} supports AT&T System V/386 assembler syntax. This is quite
-different from Intel syntax. We mention these differences because
-almost all 80386 documents used only Intel syntax. Notable differences
-between the two syntaxes are:
-
-@itemize @bullet
-@item
-@cindex immediate operands, i386
-@cindex i386 immediate operands
-@cindex register operands, i386
-@cindex i386 register operands
-@cindex jump/call operands, i386
-@cindex i386 jump/call operands
-@cindex operand delimiters, i386
-AT&T immediate operands are preceded by @samp{$}; Intel immediate
-operands are undelimited (Intel @samp{push 4} is AT&T @samp{pushl $4}).
-AT&T register operands are preceded by @samp{%}; Intel register operands
-are undelimited. AT&T absolute (as opposed to PC relative) jump/call
-operands are prefixed by @samp{*}; they are undelimited in Intel syntax.
-
-@item
-@cindex i386 source, destination operands
-@cindex source, destination operands; i386
-AT&T and Intel syntax use the opposite order for source and destination
-operands. Intel @samp{add eax, 4} is @samp{addl $4, %eax}. The
-@samp{source, dest} convention is maintained for compatibility with
-previous Unix assemblers.
-
-@item
-@cindex opcode suffixes, i386
-@cindex sizes operands, i386
-@cindex i386 size suffixes
-In AT&T syntax the size of memory operands is determined from the last
-character of the opcode name. Opcode suffixes of @samp{b}, @samp{w},
-and @samp{l} specify byte (8-bit), word (16-bit), and long (32-bit)
-memory references. Intel syntax accomplishes this by prefixes memory
-operands (@emph{not} the opcodes themselves) with @samp{byte ptr},
-@samp{word ptr}, and @samp{dword ptr}. Thus, Intel @samp{mov al, byte
-ptr @var{foo}} is @samp{movb @var{foo}, %al} in AT&T syntax.
-
-@item
-@cindex return instructions, i386
-@cindex i386 jump, call, return
-Immediate form long jumps and calls are
-@samp{lcall/ljmp $@var{section}, $@var{offset}} in AT&T syntax; the
-Intel syntax is
-@samp{call/jmp far @var{section}:@var{offset}}. Also, the far return
-instruction
-is @samp{lret $@var{stack-adjust}} in AT&T syntax; Intel syntax is
-@samp{ret far @var{stack-adjust}}.
-
-@item

-@cindex i386 sections

-_CHAPSEC__(1+_GENERIC__) Opcode Naming
-
-@cindex i386 opcode naming
-@cindex opcode naming, i386
-Opcode names are suffixed with one character modifiers which specify the
-size of operands. The letters @samp{b}, @samp{w}, and @samp{l} specify
-byte, word, and long operands. If no suffix is specified by an
-instruction and it contains no memory operands then @code{_AS__} tries to
-fill in the missing suffix based on the destination register operand
-(the last one by convention). Thus, @samp{mov %ax, %bx} is equivalent
-to @samp{movw %ax, %bx}; also, @samp{mov $1, %bx} is equivalent to
-@samp{movw $1, %bx}. Note that this is incompatible with the AT&T Unix
-assembler which assumes that a missing opcode suffix implies long
-operand size. (This incompatibility does not affect compiler output
-since compilers always explicitly specify the opcode suffix.)
-
-Almost all opcodes have the same names in AT&T and Intel format. There
-are a few exceptions. The sign extend and zero extend instructions need
-two sizes to specify them. They need a size to sign/zero extend
-@emph{from} and a size to zero extend @emph{to}. This is accomplished
-by using two opcode suffixes in AT&T syntax. Base names for sign extend
-and zero extend are @samp{movs@dots{}} and @samp{movz@dots{}} in AT&T
-syntax (@samp{movsx} and @samp{movzx} in Intel syntax). The opcode
-suffixes are tacked on to this base name, the @emph{from} suffix before
-the @emph{to} suffix. Thus, @samp{movsbl %al, %edx} is AT&T syntax for
-``move sign extend @emph{from} %al @emph{to} %edx.'' Possible suffixes,
-thus, are @samp{bl} (from byte to long), @samp{bw} (from byte to word),
-and @samp{wl} (from word to long).

-@cindex opcode prefixes, i386
-@cindex prefixes, i386
-Opcode prefixes are used to modify the following opcode. They are used
-to repeat string instructions, to provide section overrides, to perform
-bus lock operations, and to give operand and address size (16-bit
-operands are specified in an instruction by prefixing what would
-normally be 32-bit operands with a ``operand size'' opcode prefix).
-Opcode prefixes are usually given as single-line instructions with no
-operands, and must directly precede the instruction they act upon. For
-example, the @samp{scas} (scan string) instruction is repeated with:
-@smallexample
- repne
- scas
-@end smallexample
-
-Here is a list of opcode prefixes:
-
-@itemize @bullet
-@item
-@cindex section override prefixes, i386
-Section override prefixes @samp{cs}, @samp{ds}, @samp{ss}, @samp{es},
-@samp{fs}, @samp{gs}. These are automatically added by specifying

-
-@item
-@cindex size prefixes, i386
-Operand/Address size prefixes @samp{data16} and @samp{addr16}
-change 32-bit operands/addresses into 16-bit operands/addresses. Note
-that 16-bit addressing modes (i.e. 8086 and 80286 addressing modes)
-are not supported (yet).
-
-@item
-@cindex bus lock prefixes, i386
-@cindex inhibiting interrupts, i386
-The bus lock prefix @samp{lock} inhibits interrupts during

-certain instructions; see a 80386 manual for details).
-
-@item
-@cindex coprocessor wait, i386
-The wait for coprocessor prefix @samp{wait} waits for the
-coprocessor to complete the current instruction. This should never be

-@noindent
-where @var{base} and @var{index} are the optional 32-bit base and
-index registers, @var{disp} is the optional displacement, and
-@var{scale}, taking the values 1, 2, 4, and 8, multiplies @var{index}
-to calculate the address of the operand. If no @var{scale} is
-specified, @var{scale} is taken to be 1. @var{section} specifies the
-optional section register for the memory operand, and may override the
-default section register (see a 80386 manual for section register
-defaults). Note that section overrides in AT&T syntax @emph{must} have
-be preceded by a @samp{%}. If you specify a section override which
-coincides with the default section register, @code{_AS__} will @emph{not}
-output any section register override prefixes to assemble the given
-instruction. Thus, section overrides can be specified to emphasize which
-section register is used for a given memory operand.
-
-Here are some examples of Intel and AT&T style memory references:
-
-@table @asis
-@item AT&T: @samp{-4(%ebp)}, Intel: @samp{[ebp - 4]}
-@var{base} is @samp{%ebp}; @var{disp} is @samp{-4}. @var{section} is
-missing, and the default section is used (@samp{%ss} for addressing with
-@samp{%ebp} as the base register). @var{index}, @var{scale} are both missing.
-
-@item AT&T: @samp{foo(,%eax,4)}, Intel: @samp{[foo + eax*4]}
-@var{index} is @samp{%eax} (scaled by a @var{scale} 4); @var{disp} is
-@samp{foo}. All other fields are missing. The section register here
-defaults to @samp{%ds}.
-
-@item AT&T: @samp{foo(,1)}; Intel @samp{[foo]}
-This uses the value pointed to by @samp{foo} as a memory operand.
-Note that @var{base} and @var{index} are both missing, but there is only
-@emph{one} @samp{,}. This is a syntactic exception.
-
-@item AT&T: @samp{%gs:foo}; Intel @samp{gs:foo}
-This selects the contents of the variable @samp{foo} with section
-register @var{section} being @samp{%gs}.
-@end table
-
-Absolute (as opposed to PC relative) call and jump operands must be
-prefixed with @samp{*}. If no @samp{*} is specified, @code{_AS__} will
-always choose PC relative addressing for jump/call labels.
-
-Any instruction that has a memory operand @emph{must} specify its size (byte,
-word, or long) with an opcode suffix (@samp{b}, @samp{w}, or @samp{l},
-respectively).

-
-@cindex jump optimization, i386
-@cindex i386 jump optimization
-Jump instructions are always optimized to use the smallest possible
-displacements. This is accomplished by using byte (8-bit) displacement
-jumps whenever the target is sufficiently close. If a byte displacement
-is insufficient a long (32-bit) displacement is used. We do not support
-word (16-bit) displacement jumps (i.e. prefixing the jump instruction
-with the @samp{addr16} opcode prefix), since the 80386 insists upon masking
-@samp{%eip} to 16 bits after the word displacement is added.
-
-Note that the @samp{jcxz}, @samp{jecxz}, @samp{loop}, @samp{loopz},
-@samp{loope}, @samp{loopnz} and @samp{loopne} instructions only come in
-byte displacements, so that it is possible that use of these
-instructions (@code{_GCC__} does not use them) will cause the assembler to
-print an error message (and generate incorrect code). The AT&T 80386

-multiplies (base opcode @samp{0xf6}; extension 4 for @samp{mul} and 5
-for @samp{imul}) can be output only in the one operand form. Thus,
-@samp{imul %ebx, %eax} does @emph{not} select the expanding multiply;
-the expanding multiply would clobber the @samp{%edx} register, and this
-would confuse @code{_GCC__} output. Use @samp{imul %ebx} to get the
-64-bit product in @samp{%edx:%eax}.
-
-We have added a two operand form of @samp{imul} when the first operand
-is an immediate mode expression and the second operand is a register.
-This is just a shorthand, so that, multiplying @samp{%eax} by 69, for
-example, can be done with @samp{imul $69, %eax} rather than @samp{imul
-$69, %eax, %eax}.

-@c pesch@cygnus.com: we ignore the following chapters, since internals are
-@c changing rapidly. These may need to be moved to another
-@c book anyhow, if we adopt the model of user/modifier
-@c books.
-@node Maintenance, Retargeting, _MACH_DEP__, Top
-@chapter Maintaining the Assembler
-[[this chapter is still being built]]
-
-@section Design
-We had these goals, in descending priority:
-@table @b
-@item Accuracy.
-For every program composed by a compiler, @code{_AS__} should emit
-``correct'' code. This leaves some latitude in choosing addressing
-modes, order of @code{relocation_info} structures in the object
-file, @emph{etc}.
-
-@item Speed, for usual case.
-By far the most common use of @code{_AS__} will be assembling compiler
-emissions.
-
-@item Upward compatibility for existing assembler code.
-Well @dots{} we don't support Vax bit fields but everything else
-seems to be upward compatible.
-
-@item Readability.
-The code should be maintainable with few surprises. (JF: ha!)
-
-@end table
-
-We assumed that disk I/O was slow and expensive while memory was
-fast and access to memory was cheap. We expect the in-memory data
-structures to be less than 10 times the size of the emitted object
-file. (Contrast this with the C compiler where in-memory structures
-might be 100 times object file size!)
-This suggests:
-@itemize @bullet
-@item
-Try to read the source file from disk only one time. For other
-reasons, we keep large chunks of the source file in memory during
-assembly so this is not a problem. Also the assembly algorithm
-should only scan the source text once if the compiler composed the
-text according to a few simple rules.
-@item
-Emit the object code bytes only once. Don't store values and then
-backpatch later.
-@item
-Build the object file in memory and do direct writes to disk of
-large buffers.
-@end itemize
-
-RMS suggested a one-pass algorithm which seems to work well. By not
-parsing text during a second pass considerable time is saved on
-large programs (@emph{e.g.} the sort of C program @code{yacc} would
-emit).
-
-It happened that the data structures needed to emit relocation
-information to the object file were neatly subsumed into the data
-structures that do backpatching of addresses after pass 1.
-
-Many of the functions began life as re-usable modules, loosely
-connected. RMS changed this to gain speed. For example, input
-parsing routines which used to work on pre-sanitized strings now
-must parse raw data. Hence they have to import knowledge of the
-assemblers' comment conventions @emph{etc}.
-
-@section Deprecated Feature(?)s
-We have stopped supporting some features:
-@itemize @bullet
-@item
-@code{.org} statements must have @b{defined} expressions.
-@item
-Vax Bit fields (@kbd{:} operator) are entirely unsupported.
-@end itemize
-
-It might be a good idea to not support these features in a future release:
-@itemize @bullet
-@item
-@kbd{#} should begin a comment, even in column 1.
-@item
-Why support the logical line & file concept any more?
-@item
-Subsections are a good candidate for flushing.
-Depends on which compilers need them I guess.
-@end itemize
-
-@section Bugs, Ideas, Further Work
-Clearly the major improvement is DON'T USE A TEXT-READING
-ASSEMBLER for the back end of a compiler. It is much faster to
-interpret binary gobbledygook from a compiler's tables than to
-ask the compiler to write out human-readable code just so the
-assembler can parse it back to binary.
-
-Assuming you use @code{_AS__} for human written programs: here are
-some ideas:
-@itemize @bullet
-@item
-Document (here) @code{APP}.
-@item
-Take advantage of knowing no spaces except after opcode
-to speed up @code{_AS__}. (Modify @code{app.c} to flush useless spaces:
-only keep space/tabs at begin of line or between 2
-symbols.)
-@item
-Put pointers in this documentation to @file{a.out} documentation.
-@item
-Split the assembler into parts so it can gobble direct binary
-from @emph{e.g.} @code{cc}. It is silly for@code{cc} to compose text
-just so @code{_AS__} can parse it back to binary.
-@item
-Rewrite hash functions: I want a more modular, faster library.
-@item
-Clean up LOTS of code.
-@item
-Include all the non-@file{.c} files in the maintenance chapter.
-@item
-Document flonums.
-@item
-Implement flonum short literals.
-@item
-Change all talk of expression operands to expression quantities,
-or perhaps to expression arguments.
-@item
-Implement pass 2.
-@item
-Whenever a @code{.text} or @code{.data} statement is seen, we close
-of the current frag with an imaginary @code{.fill 0}. This is
-because we only have one obstack for frags, and we can't grow new
-frags for a new subsection, then go back to the old subsection and
-append bytes to the old frag. All this nonsense goes away if we
-give each subsection its own obstack. It makes code simpler in
-about 10 places, but nobody has bothered to do it because C compiler
-output rarely changes subsections (compared to ending frags with
-relaxable addresses, which is common).
-@end itemize
-
-@section Sources
-@c The following files in the @file{_AS__} directory
-@c are symbolic links to other files, of
-@c the same name, in a different directory.
-@c @itemize @bullet
-@c @item
-@c @file{atof_generic.c}

-@c @end itemize
-
-Here is a list of the source files in the @file{_AS__} directory.
-
-@table @file
-@item app.c
-This contains the pre-processing phase, which deletes comments,
-handles whitespace, etc. This was recently re-written, since app
-used to be a separate program, but RMS wanted it to be inline.
-
-@item append.c
-This is a subroutine to append a string to another string returning a
-pointer just after the last @code{char} appended. (JF: All these
-little routines should probably all be put in one file.)
-
-@item as.c
-Here you will find the main program of the assembler @code{_AS__}.
-
-@item expr.c
-This is a branch office of @file{read.c}. This understands
-expressions, arguments. Inside @code{_AS__}, arguments are called
-(expression) @emph{operands}. This is confusing, because we also talk
-(elsewhere) about instruction @emph{operands}. Also, expression
-operands are called @emph{quantities} explicitly to avoid confusion
-with instruction operands. What a mess.
-
-@item frags.c
-This implements the @b{frag} concept. Without frags, finding the
-right size for branch instructions would be a lot harder.
-
-@item hash.c
-This contains the symbol table, opcode table @emph{etc.} hashing
-functions.
-
-@item hex_value.c
-This is a table of values of digits, for use in atoi() type
-functions. Could probably be flushed by using calls to strtol(), or
-something similar.
-
-@item input-file.c
-This contains Operating system dependent source file reading
-routines. Since error messages often say where we are in reading
-the source file, they live here too. Since @code{_AS__} is intended to
-run under GNU and Unix only, this might be worth flushing. Anyway,
-almost all C compilers support stdio.
-
-@item input-scrub.c
-This deals with calling the pre-processor (if needed) and feeding the
-chunks back to the rest of the assembler the right way.
-
-@item messages.c
-This contains operating system independent parts of fatal and
-warning message reporting. See @file{append.c} above.
-
-@item output-file.c
-This contains operating system dependent functions that write an
-object file for @code{_AS__}. See @file{input-file.c} above.
-
-@item read.c
-This implements all the directives of @code{_AS__}. This also deals
-with passing input lines to the machine dependent part of the
-assembler.
-
-@item strstr.c
-This is a C library function that isn't in most C libraries yet.
-See @file{append.c} above.
-
-@item subsegs.c
-This implements subsections.
-
-@item symbols.c
-This implements symbols.
-
-@item write.c
-This contains the code to perform relaxation, and to write out
-the object file. It is mostly operating system independent, but
-different OSes have different object file formats in any case.
-
-@item xmalloc.c
-This implements @code{malloc()} or bust. See @file{append.c} above.
-
-@item xrealloc.c
-This implements @code{realloc()} or bust. See @file{append.c} above.
-
-@item atof-generic.c
-The following files were taken from a machine-independent subroutine
-library for manipulating floating point numbers and very large
-integers.
-
-@file{atof-generic.c} turns a string into a flonum internal format
-floating-point number.
-
-@item flonum-const.c
-This contains some potentially useful floating point numbers in
-flonum format.
-
-@item flonum-copy.c
-This copies a flonum.
-
-@item flonum-multip.c
-This multiplies two flonums together.
-
-@item bignum-copy.c
-This copies a bignum.
-
-@end table
-
-Here is a table of all the machine-specific files (this includes
-both source and header files). Typically, there is a
-@var{machine}.c file, a @var{machine}-opcode.h file, and an
-atof-@var{machine}.c file. The @var{machine}-opcode.h file should
-be identical to the one used by GDB (which uses it for disassembly.)
-
-@table @file
-
-@item atof-ieee.c

-@comment ~subsection Test Directory
-@comment (Note: The test directory seems to have disappeared somewhere
-@comment along the line. If you want it, you'll probably have to find a
-@comment REALLY OLD dump tape~dots{})
-@comment
-@comment The ~file{test/} directory is used for regression testing.
-@comment After you modify ~@code{_AS__}, you can get a quick go/nogo
-@comment confidence test by running the new ~@code{_AS__} over the source
-@comment files in this directory. You use a shell script ~file{test/do}.
-@comment
-@comment The tests in this suite are evolving. They are not comprehensive.
-@comment They have, however, caught hundreds of bugs early in the debugging
-@comment cycle of ~@code{_AS__}. Most test statements in this suite were naturally
-@comment selected: they were used to demonstrate actual ~@code{_AS__} bugs rather
-@comment than being written ~i{a prioi}.
-@comment
-@comment Another testing suggestion: over 30 bugs have been found simply by
-@comment running examples from this manual through ~@code{_AS__}.
-@comment Some examples in this manual are selected
-@comment to distinguish boundary conditions; they are good for testing ~@code{_AS__}.
-@comment
-@comment ~subsubsection Regression Testing
-@comment Each regression test involves assembling a file and comparing the
-@comment actual output of ~@code{_AS__} to ``known good'' output files. Both
-@comment the object file and the error/warning message file (stderr) are
-@comment inspected. Optionally the ~@code{_AS__} exit status may be checked.
-@comment Discrepencies are reported. Each discrepency means either that
-@comment you broke some part of ~@code{_AS__} or that the ``known good'' files
-@comment are now out of date and should be changed to reflect the new
-@comment definition of ``good''.
-@comment
-@comment Each regression test lives in its own directory, in a tree
-@comment rooted in the directory ~file{test/}. Each such directory
-@comment has a name ending in ~file{.ret}, where `ret' stands for
-@comment REgression Test. The ~file{.ret} ending allows ~code{find
-@comment (1)} to find all regression tests in the tree, without
-@comment needing to list them explicitly.
-@comment
-@comment Any ~file{.ret} directory must contain a file called
-@comment ~file{input} which is the source file to assemble. During
-@comment testing an object file ~file{output} is created, as well as
-@comment a file ~file{stdouterr} which contains the output to both
-@comment stderr and stderr. If there is a file ~file{output.good} in
-@comment the directory, and if ~file{output} contains exactly the
-@comment same data as ~file{output.good}, the file ~file{output} is
-@comment deleted. Likewise ~file{stdouterr} is removed if it exactly
-@comment matches a file ~file{stdouterr.good}. If file
-@comment ~file{status.good} is present, containing a decimal number
-@comment before a newline, the exit status of ~@code{_AS__} is compared
-@comment to this number. If the status numbers are not equal, a file
-@comment ~file{status} is written to the directory, containing the
-@comment actual status as a decimal number followed by newline.
-@comment
-@comment Should any of the ~file{*.good} files fail to match their corresponding
-@comment actual files, this is noted by a 1-line message on the screen during
-@comment the regression test, and you can use ~@code{find (1)} to find any
-@comment files named ~file{status}, ~file {output} or ~file{stdouterr}.

-@chapter Teaching the Assembler about a New Machine
-
-This chapter describes the steps required in order to make the
-assembler work with another machine's assembly language. This
-chapter is not complete, and only describes the steps in the
-broadest terms. You should look at the source for the
-currently supported machine in order to discover some of the
-details that aren't mentioned here.
-
-You should create a new file called @file{@var{machine}.c}, and
-add the appropriate lines to the file @file{Makefile} so that
-you can compile your new version of the assembler. This should
-be straighforward; simply add lines similar to the ones there
-for the four current versions of the assembler.
-
-If you want to be compatible with GDB, (and the current
-machine-dependent versions of the assembler), you should create
-a file called @file{@var{machine}-opcode.h} which should
-contain all the information about the names of the machine
-instructions, their opcodes, and what addressing modes they
-support. If you do this right, the assembler and GDB can share
-this file, and you'll only have to write it once. Note that
-while you're writing @code{_AS__}, you may want to use an
-independent program (if you have access to one), to make sure
-that @code{_AS__} is emitting the correct bytes. Since @code{_AS__}
-and @code{GDB} share the opcode table, an incorrect opcode
-table entry may make invalid bytes look OK when you disassemble
-them with @code{GDB}.
-
-@section Functions You will Have to Write
-
-Your file @file{@var{machine}.c} should contain definitions for
-the following functions and variables. It will need to include
-some header files in order to use some of the structures
-defined in the machine-independent part of the assembler. The
-needed header files are mentioned in the descriptions of the
-functions that will need them.
-
-@table @code
-
-@item long omagic;
-This long integer holds the value to place at the beginning of
-the @file{a.out} file. It is usually @samp{OMAGIC}, except on
-machines that store additional information in the magic-number.
-
-@item char comment_chars[];
-This character array holds the values of the characters that
-start a comment anywhere in a line. Comments are stripped off
-automatically by the machine independent part of the
-assembler. Note that the @samp{/*} will always start a
-comment, and that only @samp{*/} will end a comment started by
-@samp{*/}.
-
-@item char line_comment_chars[];
-This character array holds the values of the chars that start a
-comment only if they are the first (non-whitespace) character
-on a line. If the character @samp{#} does not appear in this
-list, you may get unexpected results. (Various
-machine-independent parts of the assembler treat the comments
-@samp{#APP} and @samp{#NO_APP} specially, and assume that lines
-that start with @samp{#} are comments.)
-
-@item char EXP_CHARS[];
-This character array holds the letters that can separate the
-mantissa and the exponent of a floating point number. Typical
-values are @samp{e} and @samp{E}.
-
-@item char FLT_CHARS[];
-This character array holds the letters that--when they appear
-immediately after a leading zero--indicate that a number is a
-floating-point number. (Sort of how 0x indicates that a
-hexadecimal number follows.)
-
-@item pseudo_typeS md_pseudo_table[];
-(@var{pseudo_typeS} is defined in @file{md.h})
-This array contains a list of the machine_dependent directives
-the assembler must support. It contains the name of each
-pseudo op (Without the leading @samp{.}), a pointer to a
-function to be called when that directive is encountered, and
-an integer argument to be passed to that function.
-
-@item void md_begin(void)
-This function is called as part of the assembler's
-initialization. It should do any initialization required by
-any of your other routines.
-
-@item int md_parse_option(char **optionPTR, int *argcPTR, char ***argvPTR)
-This routine is called once for each option on the command line
-that the machine-independent part of @code{_AS__} does not
-understand. This function should return non-zero if the option
-pointed to by @var{optionPTR} is a valid option. If it is not
-a valid option, this routine should return zero. The variables
-@var{argcPTR} and @var{argvPTR} are provided in case the option
-requires a filename or something similar as an argument. If
-the option is multi-character, @var{optionPTR} should be
-advanced past the end of the option, otherwise every letter in
-the option will be treated as a separate single-character
-option.
-
-@item void md_assemble(char *string)
-This routine is called for every machine-dependent
-non-directive line in the source file. It does all the real
-work involved in reading the opcode, parsing the operands,
-etc. @var{string} is a pointer to a null-terminated string,
-that comprises the input line, with all excess whitespace and
-comments removed.
-
-@item void md_number_to_chars(char *outputPTR,long value,int nbytes)
-This routine is called to turn a C long int, short int, or char
-into the series of bytes that represents that number on the
-target machine. @var{outputPTR} points to an array where the
-result should be stored; @var{value} is the value to store; and
-@var{nbytes} is the number of bytes in 'value' that should be
-stored.
-
-@item void md_number_to_imm(char *outputPTR,long value,int nbytes)
-This routine is called to turn a C long int, short int, or char
-into the series of bytes that represent an immediate value on
-the target machine. It is identical to the function @code{md_number_to_chars},
-except on NS32K machines.@refill
-
-@item void md_number_to_disp(char *outputPTR,long value,int nbytes)
-This routine is called to turn a C long int, short int, or char
-into the series of bytes that represent an displacement value on
-the target machine. It is identical to the function @code{md_number_to_chars},
-except on NS32K machines.@refill
-
-@item void md_number_to_field(char *outputPTR,long value,int nbytes)
-This routine is identical to @code{md_number_to_chars},
-except on NS32K machines.
-
-@item void md_ri_to_chars(struct relocation_info *riPTR,ri)
-(@code{struct relocation_info} is defined in @file{a.out.h})
-This routine emits the relocation info in @var{ri}
-in the appropriate bit-pattern for the target machine.
-The result should be stored in the location pointed
-to by @var{riPTR}. This routine may be a no-op unless you are
-attempting to do cross-assembly.
-
-@item char *md_atof(char type,char *outputPTR,int *sizePTR)
-This routine turns a series of digits into the appropriate
-internal representation for a floating-point number.
-@var{type} is a character from @var{FLT_CHARS[]} that describes
-what kind of floating point number is wanted; @var{outputPTR}
-is a pointer to an array that the result should be stored in;
-and @var{sizePTR} is a pointer to an integer where the size (in
-bytes) of the result should be stored. This routine should
-return an error message, or an empty string (not (char *)0) for
-success.
-
-@item int md_short_jump_size;
-This variable holds the (maximum) size in bytes of a short (16
-bit or so) jump created by @code{md_create_short_jump()}. This
-variable is used as part of the broken-word feature, and isn't
-needed if the assembler is compiled with
-@samp{-DWORKING_DOT_WORD}.
-
-@item int md_long_jump_size;
-This variable holds the (maximum) size in bytes of a long (32
-bit or so) jump created by @code{md_create_long_jump()}. This
-variable is used as part of the broken-word feature, and isn't
-needed if the assembler is compiled with
-@samp{-DWORKING_DOT_WORD}.
-
-@item void md_create_short_jump(char *resultPTR,long from_addr,
-@code{long to_addr,fragS *frag,symbolS *to_symbol)}
-This function emits a jump from @var{from_addr} to @var{to_addr} in
-the array of bytes pointed to by @var{resultPTR}. If this creates a
-type of jump that must be relocated, this function should call
-@code{fix_new()} with @var{frag} and @var{to_symbol}. The jump
-emitted by this function may be smaller than @var{md_short_jump_size},
-but it must never create a larger one.
-(If it creates a smaller jump, the extra bytes of memory will not be
-used.) This function is used as part of the broken-word feature,
-and isn't needed if the assembler is compiled with
-@samp{-DWORKING_DOT_WORD}.@refill
-
-@item void md_create_long_jump(char *ptr,long from_addr,
-@code{long to_addr,fragS *frag,symbolS *to_symbol)}
-This function is similar to the previous function,
-@code{md_create_short_jump()}, except that it creates a long
-jump instead of a short one. This function is used as part of
-the broken-word feature, and isn't needed if the assembler is
-compiled with @samp{-DWORKING_DOT_WORD}.
-
-@item int md_estimate_size_before_relax(fragS *fragPTR,int segment_type)
-This function does the initial setting up for relaxation. This
-includes forcing references to still-undefined symbols to the
-appropriate addressing modes.
-
-@item relax_typeS md_relax_table[];
-(relax_typeS is defined in md.h)
-This array describes the various machine dependent states a
-frag may be in before relaxation. You will need one group of
-entries for each type of addressing mode you intend to relax.
-
-@item void md_convert_frag(fragS *fragPTR)
-(@var{fragS} is defined in @file{as.h})
-This routine does the required cleanup after relaxation.
-Relaxation has changed the type of the frag to a type that can
-reach its destination. This function should adjust the opcode
-of the frag to use the appropriate addressing mode.
-@var{fragPTR} points to the frag to clean up.
-
-@item void md_end(void)
-This function is called just before the assembler exits. It
-need not free up memory unless the operating system doesn't do
-it automatically on exit. (In which case you'll also have to
-track down all the other places where the assembler allocates
-space but never frees it.)
-
-@end table
-
-@section External Variables You will Need to Use
-
-You will need to refer to or change the following external variables
-from within the machine-dependent part of the assembler.
-
-@table @code
-@item extern char flagseen[];
-This array holds non-zero values in locations corresponding to
-the options that were on the command line. Thus, if the
-assembler was called with @samp{-W}, @var{flagseen['W']} would
-be non-zero.
-
-@item extern fragS *frag_now;
-This pointer points to the current frag--the frag that bytes
-are currently being added to. If nothing else, you will need
-to pass it as an argument to various machine-independent
-functions. It is maintained automatically by the
-frag-manipulating functions; you should never have to change it
-yourself.
-
-@item extern LITTLENUM_TYPE generic_bignum[];
-(@var{LITTLENUM_TYPE} is defined in @file{bignum.h}.
-This is where @dfn{bignums}--numbers larger than 32 bits--are
-returned when they are encountered in an expression. You will
-need to use this if you need to implement directives (or
-anything else) that must deal with these large numbers.
-@code{Bignums} are of @code{segT} @code{SEG_BIG} (defined in
-@file{as.h}, and have a positive @code{X_add_number}. The
-@code{X_add_number} of a @code{bignum} is the number of
-@code{LITTLENUMS} in @var{generic_bignum} that the number takes
-up.
-
-@item extern FLONUM_TYPE generic_floating_point_number;
-(@var{FLONUM_TYPE} is defined in @file{flonum.h}.
-The is where @dfn{flonums}--floating-point numbers within
-expressions--are returned. @code{Flonums} are of @code{segT}
-@code{SEG_BIG}, and have a negative @code{X_add_number}.
-@code{Flonums} are returned in a generic format. You will have
-to write a routine to turn this generic format into the
-appropriate floating-point format for your machine.
-
-@item extern int need_pass_2;
-If this variable is non-zero, the assembler has encountered an
-expression that cannot be assembled in a single pass. Since
-the second pass isn't implemented, this flag means that the
-assembler is punting, and is only looking for additional syntax
-errors. (Or something like that.)
-
-@item extern segT now_seg;
-This variable holds the value of the section the assembler is
-currently assembling into.
-
-@end table
-
-@section External functions will you need
-
-You will find the following external functions useful (or
-indispensable) when you're writing the machine-dependent part
-of the assembler.
-
-@table @code
-
-@item char *frag_more(int bytes)
-This function allocates @var{bytes} more bytes in the current
-frag (or starts a new frag, if it can't expand the current frag
-any more.) for you to store some object-file bytes in. It
-returns a pointer to the bytes, ready for you to store data in.
-
-@item void fix_new(fragS *frag, int where, short size, symbolS *add_symbol, symbolS *sub_symbol, long offset, int pcrel)
-This function stores a relocation fixup to be acted on later.
-@var{frag} points to the frag the relocation belongs in;
-@var{where} is the location within the frag where the relocation begins;
-@var{size} is the size of the relocation, and is usually 1 (a single byte),
- 2 (sixteen bits), or 4 (a longword).
-The value @var{add_symbol} @minus{} @var{sub_symbol} + @var{offset}, is added to the byte(s)
-at _0__@var{frag->literal[where]}_1__. If @var{pcrel} is non-zero, the address of the
-location is subtracted from the result. A relocation entry is also added
-to the @file{a.out} file. @var{add_symbol}, @var{sub_symbol}, and/or
-@var{offset} may be NULL.@refill
-
-@item char *frag_var(relax_stateT type, int max_chars, int var,
-@code{relax_substateT subtype, symbolS *symbol, char *opcode)}
-This function creates a machine-dependent frag of type @var{type}
-(usually @code{rs_machine_dependent}).
-@var{max_chars} is the maximum size in bytes that the frag may grow by;
-@var{var} is the current size of the variable end of the frag;
-@var{subtype} is the sub-type of the frag. The sub-type is used to index into
-@var{md_relax_table[]} during @code{relaxation}.
-@var{symbol} is the symbol whose value should be used to when relax-ing this frag.
-@var{opcode} points into a byte whose value may have to be modified if the
-addressing mode used by this frag changes. It typically points into the
-@var{fr_literal[]} of the previous frag, and is used to point to a location
-that @code{md_convert_frag()}, may have to change.@refill
-
-@item void frag_wane(fragS *fragPTR)
-This function is useful from within @code{md_convert_frag}. It
-changes a frag to type rs_fill, and sets the variable-sized
-piece of the frag to zero. The frag will never change in size
-again.
-
-@item segT expression(expressionS *retval)
-(@var{segT} is defined in @file{as.h}; @var{expressionS} is defined in @file{expr.h})
-This function parses the string pointed to by the external char
-pointer @var{input_line_pointer}, and returns the section-type
-of the expression. It also stores the results in the
-@var{expressionS} pointed to by @var{retval}.
-@var{input_line_pointer} is advanced to point past the end of
-the expression. (@var{input_line_pointer} is used by other
-parts of the assembler. If you modify it, be sure to restore
-it to its original value.)
-
-@item as_warn(char *message,@dots{})
-If warning messages are disabled, this function does nothing.
-Otherwise, it prints out the current file name, and the current
-line number, then uses @code{fprintf} to print the
-@var{message} and any arguments it was passed.
-
-@item as_bad(char *message,@dots{})
-This function should be called when @code{_AS__} encounters
-conditions that are bad enough that @code{_AS__} should not
-produce an object file, but should continue reading input and
-printing warning and bad error messages.
-
-@item as_fatal(char *message,@dots{})
-This function prints out the current file name and line number,
-prints the word @samp{FATAL:}, then uses @code{fprintf} to
-print the @var{message} and any arguments it was passed. Then
-the assembler exits. This function should only be used for
-serious, unrecoverable errors.
-
-@item void float_const(int float_type)
-This function reads floating-point constants from the current
-input line, and calls @code{md_atof} to assemble them. It is
-useful as the function to call for the directives
-@samp{.single}, @samp{.double}, @samp{.float}, etc.
-@var{float_type} must be a character from @var{FLT_CHARS}.
-
-@item void demand_empty_rest_of_line(void);
-This function can be used by machine-dependent directives to
-make sure the rest of the input line is empty. It prints a
-warning message if there are additional characters on the line.
-
-@item long int get_absolute_expression(void)
-This function can be used by machine-dependent directives to
-read an absolute number from the current input line. It
-returns the result. If it isn't given an absolute expression,
-it prints a warning message and returns zero.
-
-@end table
-
-
-@section The concept of Frags
-
-This assembler works to optimize the size of certain addressing
-modes. (e.g. branch instructions) This means the size of many
-pieces of object code cannot be determined until after assembly
-is finished. (This means that the addresses of symbols cannot be
-determined until assembly is finished.) In order to do this,
-@code{_AS__} stores the output bytes as @dfn{frags}.
-
-Here is the definition of a frag (from @file{as.h})
-@smallexample
-struct frag
-@{
- long int fr_fix;
- long int fr_var;
- relax_stateT fr_type;
- relax_substateT fr_substate;
- unsigned long fr_address;
- long int fr_offset;
- struct symbol *fr_symbol;
- char *fr_opcode;
- struct frag *fr_next;
- char fr_literal[];
-@}
-@end smallexample
-
-@table @var
-@item fr_fix
-is the size of the fixed-size piece of the frag.
-
-@item fr_var
-is the maximum (?) size of the variable-sized piece of the frag.
-
-@item fr_type
-is the type of the frag.
-Current types are:
-rs_fill
-rs_align
-rs_org
-rs_machine_dependent
-
-@item fr_substate
-This stores the type of machine-dependent frag this is. (what
-kind of addressing mode is being used, and what size is being
-tried/will fit/etc.
-
-@item fr_address
-@var{fr_address} is only valid after relaxation is finished.
-Before relaxation, the only way to store an address is (pointer
-to frag containing the address) plus (offset into the frag).
-
-@item fr_offset
-This contains a number, whose meaning depends on the type of
-the frag.
-for machine_dependent frags, this contains the offset from
-fr_symbol that the frag wants to go to. Thus, for branch
-instructions it is usually zero. (unless the instruction was
-@samp{jba foo+12} or something like that.)
-
-@item fr_symbol
-for machine_dependent frags, this points to the symbol the frag
-needs to reach.
-
-@item fr_opcode
-This points to the location in the frag (or in a previous frag)
-of the opcode for the instruction that caused this to be a frag.
-@var{fr_opcode} is needed if the actual opcode must be changed
-in order to use a different form of the addressing mode.
-(For example, if a conditional branch only comes in size tiny,
-a large-size branch could be implemented by reversing the sense
-of the test, and turning it into a tiny branch over a large jump.
-This would require changing the opcode.)
-
-@var{fr_literal} is a variable-size array that contains the
-actual object bytes. A frag consists of a fixed size piece of
-object data, (which may be zero bytes long), followed by a
-piece of object data whose size may not have been determined
-yet. Other information includes the type of the frag (which
-controls how it is relaxed),
-
-@item fr_next
-This is the next frag in the singly-linked list. This is
-usually only needed by the machine-independent part of
-@code{_AS__}.

-
-@display
-Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.

-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.

-
-@unnumberedsec Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software---to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.

-@iftex
-@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end iftex
-@ifinfo
-@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end ifinfo
-
-@enumerate
-@item
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-@item
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-@item
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-@enumerate a
-@item
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-@item
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-@item
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-@end enumerate
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-@item
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-@enumerate a
-@item
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-@item
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-@item
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-@end enumerate
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-@item
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-@item
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-@item
-If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-@item
-If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-@item
-The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and ``any
-later version'', you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-@item
-If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.

-@unnumberedsec Applying These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the ``copyright'' line and a pointer to where the full notice is found.

-` to preprocess some GNU manuals'
-` $Id: pretex.m4,v 1.1 1993/10/02 21:00:25 pk Exp $'
-
-I. INTRODUCTION
-
-This collection of M4 macros is meant to help in pre-processing texinfo
-files to allow configuring them by hosts; for example, the reader of an
-as manual who only has access to a 386 may not really want to see crud about
-VAXen.
-
-A preprocessor is used, rather than extending texinfo, because this
-way we can hack the conditionals in only one place; otherwise we would
-have to write TeX macros, update makeinfo, and update the Emacs
-info-formatting functions.
-
-II. COMPATIBILITY
-
-These macros should work with GNU m4 and System V m4; they do not work
-with Sun or Berkeley M4.
-
-III. USAGE
-
-A. M4 INVOCATION
-Assume this file is called "pretex.m4". Then, to preprocess a
-document "mybook.texinfo" you might do something like the following:
-
- m4 pretex.m4 none.m4 PARTIC.m4 mybook.texinfo >mybook-PARTIC.texinfo
-
----where your path is set to find GNU or SysV "m4", and the other m4
-files mentioned are as follows:
-
- none.m4: A file that defines, as 0, all the options you might
- want to turn on using the conditionals defined below.
- Unlike the C preprocessor, m4 does not default
- undefined macros to 0. For example, here is a "none.m4"
- I have been using:
- _divert__(-1)
-
- _define__(<_ALL_ARCH__>,<0>)
- _define__(<_INTERNALS__>,<0>)
-
- _define__(<_AMD29K__>,<0>)
- _define__(<_I80386__>,<0>)
- _define__(<_I960__>,<0>)
- _define__(<_M680X0__>,<0>)
- _define__(<_SPARC__>,<0>)
- _define__(<_VAX__>,<0>)
-
- _divert__<>
-
- PARTIC.m4: A file that turns on whichever options you actually
- want the manual configured for, in this particular
- instance. Its contents are similar to one or more of
- the lines in "none.m4", but of course the second
- argument to _define__ is <1> rather than <0>.
-
- This is also a convenient place to _define__ any macros
- that you want to expand to different text for
- different configurations---for example, the name of
- the program being described.
-
-Naturally, these are just suggested conventions; you could put your macro
-definitions in any files or combinations of files you like.
-
-These macros use the characters < and > as m4 quotes; if you need
-these characters in your text, you will also want to use the macros
-_0__ and _1__ from this package---see the description of "Quote
-Handling" in the "Implementation" section below.
-
-B. WHAT GOES IN THE PRE-TEXINFO SOURCE
-
-For the most part, the text of your book. In addition, you can
-have text that is included only conditionally, using the macros
-_if__ and _fi__ defined below. They BOTH take an argument! This is
-primarily meant for readability (so a human can more easily see what
-conditional end matches what conditional beginning), but the argument
-is actually used in the _fi__ as well as the _if__ implementation.
-You should always give a _fi__ the same argument as its matching
-_if__. Other arguments may appear to work for a while, but are almost
-certain to produce the wrong output for some configurations.
-
-For example, here is an excerpt from the very beginning of the
-documentation for GNU as, to name the info file appropriately for
-different configurations:
- _if__(_ALL_ARCH__)
- @setfilename as.info
- _fi__(_ALL_ARCH__)
- _if__(_M680X0__ && !_ALL_ARCH__)
- @setfilename as-m680x0.info
- _fi__(_M680X0__ && !_ALL_ARCH__)
- _if__(_AMD29K__ && !_ALL_ARCH__)
- @setfilename as-29k.info
- _fi__(_AMD29K__ && !_ALL_ARCH__)
-
-Note that you can use Boolean expressions in the arguments; the
-expression language is that of the built-in m4 macro `eval', described
-in the m4 manual.
-
-IV. IMPLEMENTATION
-
-A.PRIMITIVE RENAMING
-First, we redefine m4's built-ins to avoid conflict with plain text.
-The naming convention used is that our macros all begin with a single
-underbar and end with two underbars. The asymmetry is meant to avoid
-conflict with some other conventions (which we may want to document) that
-are intended to avoid conflict, like ANSI C predefined macros.
-
-define(`_undefine__',defn(`undefine'))
-define(`_define__',defn(`define'))
-define(`_defn__',defn(`defn'))
-define(`_ppf__',`_define__(`_$1__',_defn__(`$1'))_undefine__(`$1')')
-_ppf__(`builtin')
-_ppf__(`changecom')
-_ppf__(`changequote')
-_ppf__(`decr')
-_ppf__(`define')
-_ppf__(`defn')
-_ppf__(`divert')
-_ppf__(`divnum')
-_ppf__(`dnl')
-_ppf__(`dumpdef')
-_ppf__(`errprint')
-_ppf__(`esyscmd')
-_ppf__(`eval')
-_ppf__(`format')
-_ppf__(`ifdef')
-_ppf__(`ifelse')
-_ppf__(`include')
-_ppf__(`incr')
-_ppf__(`index')
-_ppf__(`len')
-_ppf__(`m4exit')
-_ppf__(`m4wrap')
-_ppf__(`maketemp')
-_ppf__(`patsubst')
-_ppf__(`popdef')
-_ppf__(`pushdef')
-_ppf__(`regexp')
-_ppf__(`shift')
-_ppf__(`sinclude')
-_ppf__(`substr')
-_ppf__(`syscmd')
-_ppf__(`sysval')
-_ppf__(`traceoff')
-_ppf__(`traceon')
-_ppf__(`translit')
-_ppf__(`undefine')
-_ppf__(`undivert')
-_ppf__(`unix')
-
-B. QUOTE HANDLING.
-
-The characters used as quotes by M4, by default, are unfortunately
-quite likely to occur in ordinary text. To avoid surprises, we will
-use the characters <> ---which are just as suggestive (more so to
-Francophones, perhaps) but a little less common in text (save for
-those poor Francophones. You win some, you lose some). Still, we
-expect also to have to set < and > occasionally in text; to do that,
-we define a macro to turn off quote handling (_0__) and a macro to
-turn it back on (_1__), according to our convention.
-
- BEWARE: This seems to make < and > unusable as relational operations
- in calls to the builtin "eval". So far I've gotten
- along without; but a better choice may be possible.
-
-Note that we postponed this for a while, for convenience in discussing
-the issue and in the primitive renaming---not to mention in defining
-_0__ and _1__ themselves! However, the quote redefinitions MUST
-precede the _if__ / _fi__ definitions, because M4 will expand the text
-as given---if we use the wrong quotes here, we will get the wrong
-quotes when we use the conditionals.
-
-_define__(_0__,`_changequote__(,)')_define__(_1__,`_changequote__(<,>)')
-_1__
-
-C. CONDITIONALS
-
-We define two macros, _if__ and _fi__. BOTH take arguments! This is
-meant both to help the human reader match up a _fi__ with its
-corresponding _if__ and to aid in the implementation. You may use the
-full expression syntax supported by M4 (see docn of `eval' builtin in
-the m4 manual).
-
-The conditional macros are carefully defined to avoid introducing
-extra whitespace (i.e., blank lines or blank characters). One side
-effect exists---
-
- BEWARE: text following an `_if__' on the same line is
- DISCARDED even if the condition is true; text
- following a `_fi__' on the same line is also
- always discarded.
-
-The recommended convention is to always place _if__ and _fi__ on a
-line by themselves. This will also aid the human reader. TeX won't
-care about the line breaks; as for info, you may want to insert calls
-to `@refill' at the end of paragraphs containing conditionalized text,
-where you don't want line breaks separating unconditional from
-conditional text. info formatting will then give you nice looking
-paragraphs in the info file.
-
-Nesting: conditionals are designed to nest, in the following way:
-*nothing* is output between an outer pair of false conditionals, even
-if there are true conditionals inside. A false conditional "defeats"
-all conditionals within it. The counter _IF_FS__ is used to
-implement this; kindly avoid redefining it directly.
-
-_define__(<_IF_FS__>,<0>)
-
-NOTE: The definitions for our "pushf" and "popf" macros use eval
-rather than incr and decr, because GNU m4 (0.75) tries to call eval
-for us when we say "incr" or "decr"---but doesn't notice we've changed
-eval's name.

-
-D. CHAPTER/SECTION MACRO
-In a parametrized manual, the heading level may need to be calculated;
-for example, a manual that has a chapter on machine dependencies
-should be conditionally structured as follows:
- - IF the manual is configured for a SINGLE machine type, use
-the chapter heading for that machine type, and run headings down
-from there (top level for a particular machine is chapter, then within
-that we have section, subsection etc);
- - ELSE, if MANY machine types are described in the chapter,
-use a generic chapter heading such as "@chapter Machine Dependencies",
-use "section" for the top level description of EACH machine, and run
-headings down from there (top level for a particular machine is
-section, then within that we have subsection, subsubsection etc).
-
-The macro <_CHAPSEC__> is for this purpose: its argument is evaluated (so
-you can construct expressions to express choices such as above), then
-expands as follows:
- 0: @chapter
- 1: @section
- 2: @subsection
- 3: @subsubsection
- ...and so on.
-
-_define__(<_CHAPSEC__>,<@_cs__(_eval__($1))>)
-_define__(<_cs__>,<_ifelse__(
- 0, $1, <chapter>,
- 1, $1, <section>,
- <sub<>_cs__(_eval__($1 - 1))>)>)

-* "minus_X"[] is supposed to be 10^(2^-X) expressed in base 2^16. *
-* The radix point is just AFTER the highest element of the [] *
-* *
-* Because bc rounds DOWN for printing (I think), the lowest *
-* significance littlenums should probably have 1 added to them. *

-.SH NAME
-mt \- control magnetic tape drive operation
-.SH SYNOPSIS
-.B mt
-[\-V] [\-f device] [\-\-file=device] [\-\-version]
-operation [count]
-.SH DESCRIPTION
-This manual page
-documents the GNU version of
-.BR mt .
-.B mt
-performs the given
-.IR operation ,
-which must be one of the tape operations listed below, on a tape
-drive.
-.PP
-The default tape device to operate on is taken from the file
-.I /usr/include/sys/mtio.h
-when
-.B mt
-is compiled. It can be overridden by giving a device file name in
-the environment variable
-.BR TAPE
-or by a command line option (see below), which also overrides the
-environment variable.
-.PP
-The device must be either a character special file or a
-remote tape drive. To use a tape drive on another machine as the
-archive, use a filename that starts with `HOSTNAME:'. The
-hostname can be preceded by a username and an `@' to access the remote
-tape drive as that user, if you have permission to do so (typically an
-entry in that user's `~/.rhosts' file).
-.PP
-The available operations are listed below. Unique abbreviations are
-accepted. Not all operations are available on all systems, or work on
-all types of tape drives.
-Some operations optionally take a repeat count, which can be given
-after the operation name and defaults to 1.
-.IP "eof, weof"
-Write
-.I count
-EOF marks at current position.
-.IP fsf
-Forward space
-.I count
-files.
-The tape is positioned on the first block of the next file.
-.IP bsf
-Backward space
-.I count
-files.
-The tape is positioned on the first block of the next file.
-.IP fsr
-Forward space
-.I count
-records.
-.IP bsr
-Backward space
-.I count
-records.
-.IP bsfm
-Backward space
-.I count
-file marks.
-The tape is positioned on the beginning-of-the-tape side of
-the file mark.
-.IP asf
-Absolute space to file number
-.IR count .
-Equivalent to rewind followed by fsf
-.IR count .
-.IP eom
-Space to the end of the recorded media on the tape
-(for appending files onto tapes).
-.IP rewind
-Rewind the tape.
-.IP "offline, rewoffl"
-Rewind the tape and, if applicable, unload the tape.
-.IP status
-Print status information about the tape unit.
-.IP retension
-Rewind the tape, then wind it to the end of the reel,
-then rewind it again.
-.IP erase
-Erase the tape.
-.PP
-.B mt
-exits with a status of 0 if the operation succeeded, 1 if the
-operation or device name given was invalid, or 2 if the operation
-failed.
-.SS OPTIONS
-.TP
-.I "\-f, \-\-file=device"
-Use
-.I device
-as the file name of the tape drive to operate on.
-To use a
-tape drive on another machine, use a filename that
-starts with `HOSTNAME:'. The hostname can be preceded by a
-username and an `@' to access the remote tape drive as that user, if
-you have permission to do so (typically an entry in that user's
-`~/.rhosts' file).
-.TP
-.I "\-V, \-\-version"
-Print the version number of
-.BR mt .

- fucntion start, not >).
-
- * breakpoint.c (_initialize_breakpoint): Change "delete" internal

- to the manual for this version of gdb.
-
- * blockframe.c (get_prev_frame_info): Now we get saved address and
- check for validity before we check for leafism. This means that
- we will catch the fact that we are in start, but we will miss any
- fns that start calls without an fp. This should be fine.
-
- * m-*.h (FRAME_CHAIN): Modified to return 0 if we are in start.

-
- * dbxread.c (symbol_file_command): Use malloc to allocate the
- space for the string table in symbol_file_command (and setup a
- cleanup for this). This allows a more graceful error failure if
- there isn't any memory availible (and probably allows more memory
- to be avail, depending on the machine).
-
- Additional mods for handling GNU C++ (from Tiemann):
- * dbxread.c (read_type): Added case for '#' type (method type, I
- believe).
- (read_struct_type): If type code is undefined, make the main

- type_print_base): Added code to print method args correctly.
- * values.c (value_virtual_fn_field): Modify access to virtual

-
-Wed Mar 29 13:19:34 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)

-
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Set address of sp saved in
- frame to value of fp (rather than value of sp in current frame).
-
- * expread.y: Allow "unsigned" as a type itself, as well as a type

-
- * defs.h, utils.c (initialize_more_filter, fprintf_filtered,

-
-Tue Feb 14 11:11:24 1989 Randall Smith (randy at gluteus.ai.mit.edu)
-

- too often.
-
- * command.c (lookup_cmd, _initialize_command): Changed '!' so that
- it was no longer a shell escape. "sh" must be used.
-
- * main.c (command_line_input, set_history_expansion,
- initialize_main): Turned history expansion on, made it the
- default, and only execute it if the first character in the line is
- a '!'.

- the gun some time before release).
-
- * gdb.texinfo: Added sections (adapted from Brian's notes) on
- command line editing and history expansion.
-
- * main.c (set_command_editing, initialize_main): Modified name to
- set_editing and modified command to "set editing".
-
- * Makefile: Put in dependencies for READLINEOBJS.
-
- * main.c (history_info, command_info): Combined into new command
- info; deleted history_info.
- (initialize_main): Deleted "info history" command; it was
- interfering with the value history.
-
- * coffread.c (enter_linenos): Modified to do bit copy instead of
- pointer dereference, since the clipper machine can't handle having
- longs on short boundaries.
- (read_file_hdr): Added code to get number of syms for clipper.
-
- * stack.c (return_command): Fixed method for checking when all of
- the necessary frames had been popped.
-

-
- * dbxread.c (read_dbx_symtab): Split assignment to namestring into

- produce the lowest possible execution time. Commented (at top of
- switch) which code I duplicated.
-
- * dbxread.c (read_dbx_symtab): Modified which variables were
- register and deleted several variables which weren't used. Also
- eliminated 'F' choice from subswitch, broke out strcmp's, reversed
- compare on line 1986, and elminated test for !namestring[0]; it is
- caught by following test for null index of ':'.
-
-Sun Feb 12 12:57:56 1989 Randall Smith (randy at plantaris.ai.mit.edu)
-
- * main.c (gdb_completer_word_break_characters): Turned \~ into ~.

-
- * symtab.c (find_pc_psymtab): Created; checks all psymtab's till
- it finds pc.
- (find_pc_symtab): Used; fatal error if psymtab found is readin
- (should have been caught in symtab loop).
- (lookup_symbol): Added check before scan through partial symtab
- list for symbol name to be on the misc function vector (only if in
- VAR_NAMESPACE). Also made sure that psymtab's weren't fooled with
- if they had already been read in.
- (list_symbols): Checked through misc_function_vector for matching
- names if we were looking for functions.
- (make_symbol_completion_list): Checked through
- misc_function_vector for matching names.
- * dbxread.c (read_dbx_symtab): Don't bother to do processing on
- global function types; this will be taken care of by the
- misc_function hack.
-

- description of partial symbol allocation into a specific kind of
- structure.
-
- (read_dbx_symtab, process_symbol_for_psymtab): Moved most of
- process_symbol_for_psymtab up into read_dbx_symtab, moved a couple
- of symbol types down to the ingore section, streamlined (I hope)
- code some, modularized access to psymbol lists.
-
-Thu Feb 9 13:21:19 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-

-
- * config.gdb: Added a couple of aliases for machines in the
- script.
-

-
- * *-dep.c: Deleted definition of COFF_FORMAT if AOUTHDR was
- defined since 1) We *may* (recent mail message) want to define

- a typedef in coff encapsulation setups. Also removed #define's of
- AOUTHDR if AOUTHDR is already defined (inside of coff format).
- * core.c, dbxread.c: Removed #define's of AOUTHDR if AOUTHDR is

-
- * dbxread.c (read_range_type): Added code to be more picky about
- recognizing builtins as range types, to treat types defined as
- subranges of themselves to be subranges of int, and to recognize

-
- * m-vax.h: Removed definition of FUNCTION_HAS_FRAME_POINTER.

- running section making it clear that users may invoke subroutines
- directly from gdb.
-
- * blockframe.c: Setup a default definition for the macro
- FUNCTION_HAS_FRAME_POINTER.
- (get_prev_frame_info): Used this macro instead of checking
- SKIP_PROLOGUE directly.
- * m-vax.h: Overroad definition; all functions on the vax have

- would be done were the ones put on the chain *after* the current
- location.
-
- * m-*.h (FRAME_CHAIN_VALID): Removed check on pc in the current
- frame being valid.
- * blockframe.c (get_prev_frame_info): Made the assumption that if
- a frame's pc value was within the first object file (presumed to
- be /lib/crt0.o), that we shouldn't go any higher.
-
- * infrun.c (wait_for_inferior): Do *not* execute check for stop pc
- at step_resume_break if we are proceeding over a breakpoint (ie.
- if trap_expected != 0).
-
- * Makefile: Added -g to LDFLAGS.
-
- * m-news.h (POP_FRAME) Fixed typo.
-
- * printcmd.c (print_frame_args): Modified to print out register
- params in order by .stabs entry, not by register number.
-
- * sparc-opcode.h: Changed declaration of (struct
- arith_imm_fmt).simm to be signed (as per architecture manual).
- * sparc-pinsn.c (fprint_addr1, print_insn): Forced a cast to an
- int, so that we really would get signed behaivior (default for sun
- cc is unsigned).
-
- * i386-dep.c (i386_get_frame_setup): Replace function with new
- function provided by pace to fix bug in recognizing prologue.
-

-
- * infcmd.c (run_command): Changed error message to "Program not

-
- * value.h: Added lval: "lval_reg_frame_relative" to indicate a
- register that must be interpeted relative to a frame. Added
- single entry to value structure: "frame", used to indicate which
- frame a relative regnum is relative to.
- * findvar.c (value_from_register): Modified to correctly setup
- these fields when needed. Deleted section to fiddle with last
- register copied on little endian machine; multi register
- structures will always occupy an integral number of registers.
- (find_saved_register): Made extern.
- * values.c (allocate_value, allocate_repeat_value): Zero frame
- field on creation.
- * valops.c (value_assign): Added case for lval_reg_frame_relative;

- find_saved_register as being external.
- * value.h: Removed addition of kludgy structure; thoroughly
- commented file.
- * values.c (free_value, free_all_values, clear_value_history,
- set_internalvar, clear_internavars): Killed free_value.

-
- * value.h: Added lval_reg_partsaved to enum lval_type and
- commented enum lval_type. Commented value structure.
- Added "struct partial_register_saved" to value struct; added
- macros to deal with structure to value.h.
- * values.c (free_value): Created; special cases lval_reg_partsaved
- (which has a pointer to an array which also needs to be free).
- (free_all_values, clear_value_history, set_internalvar,
- clear_internalvars): Modified to use free_values.

- these files; they aren't needed.
-
- * README: Added comment about bug reporting and comment about
- xgdb.
-
- * Makefile: Added note to HPUX dependent section warning about
- problems if compiled with gcc and mentioning the need to add
- -Ihp-include to CFLAGS if you compile on those systems. Added a

- coff encapsulate feature also. * hp-include: Made symbolic link
- over to /gp/gnu/binutils.
-
- * Makefile: Added TSOBS NTSOBS OBSTACK and REGEX to list of things
- to delete in "make clean". Also changed "squeakyclean" target as
- "realclean".
-
- * findvar.c (value_from_register): Added assignment of VALUE_LVAL
- to be lval_memory when that is appropriate (original code didn't
- bother because it assumed that it was working with a pre lval
- memoried value).
-
- * expread.y (yylex): Changed to only return type THIS if the
- symbol "$this" is defined in some block superior or equal to the
- current expression context block.

-
- * m-*.h (FRAME_CHAIN_VALID): On machines which check the relation

- case someone stops in _start).
-
- * findvar.c (value_of_register): Changed error message in case of
- no inferior or core file.

- (core_file_command): Used N_SET_MAGIC instead of assignment to a_magic.
- (exec_file_command): Stuck in a HEADER_SEEK_FD.
- * infrun.c, remote.c: Added an include of a.out.encap.h if
- COFF_ENCAPSULATE defined. This is commented out in these two
- files, I presume because the definitions aren't used.

-
- * stack.c (set_backtrace_limit_command, backtrace_limit_info,
- bactrace_command, _initialize_stack): Removed modifications for

-
- * m-sparc.h: Deleted definition of SUN4_COMPILER_BUG; was designed
- to avoid something that I consider a bug in our code, not theirs,
- and which I fixed earlier. Also deleted definition of
- CANNOT_USE_ARBITRARY_FRAME; no longer used anywhere.
- FRAME_SPECIFICATION_DYADIC used instead.
-
- * infrun.c (wait_for_inferior): On the sun 4, if a function
- doesn't have a prologue, a next over it single steps into it.
- This gets around the problem of a "call .stret4" at the end of
- functions returning structures.
- * m-sparc.h: Defined SUN4_COMPILER_FEATURE.
-
- * main.c (copying_info): Seperated the last printf into two
- printfs. The 386 compiler will now handle it.
-
- * i386-pinsn.c, i386-dep.c: Moved print_387_control_word,
- print_387_status_word, print_387_status, and i386_float_info to

- pointer.
-
- * i386-dep.c (i386_follow_jump): Modified to deal with

- frame if frame is non-zero.
-
- * printcmd.c (print_scalar_formatted): Implemented /g size for
- hexadecimal format on machines without an 8 byte integer type. It
- seems to be non-trivial to implement /g for other formats.

- fileter.
-
-Wed Dec 14 13:27:04 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * expread.y: Converted all calls to write_exp_elt from the parser
- to calls to one of write_exp_elt_{opcode, sym, longcst, dblcst,
- char, type, intern}. Created all of these routines. This gets
- around possible problems in passing one of these things in one ear
- and getting something different out the other. Eliminated
- SUN4_COMPILER_BUG ifdef's; they are now superfluous.
-

-
- * symmisc.c (free_psymtab, free_all_psymtabs): Deleted
- free_psymtab subroutine.
-
- * symtab.h: Removed num_includes and includes from partial_symtab
- structure; no longer needed now that all include files have their
- own psymtab.

- their own list; included in call to end_psymtab.
- * symmisc.c (free_psymtab): Don't free includes.

- this function from pinsn.c to dep.c.
-
- * Makefile: Put in warnings about compiling with gcc (non-ansi
- include files) and compiling with shared libs on Sunos 4.0 (can't
- debug something that's been compiled that way).
-
- * sparc-pinsn.c: Put in a completely new file (provided by
- Tiemann) to handle floating point disassembly, load and store
- instructions, and etc. better. Made the modifications this file
- (ChangeLog) list for sparc-pinsn.c again.
-
- * symtab.c (output_source_filename): Included "more" emulation hack.
-
- * symtab.c (output_source_filename): Initialized COLUMN to 0.
- (sources_info): Modified to not print out a line for
- all of the include files within a partial symtab (since
- they have pst's of their own now). Also modified to
- make a distinction between those pst's read in and
- those not.
-
- * infrun.c: Included void declaration of single_step() if it's
- going to be used.
- * sparc-dep.c (single_step): Moved function previous to use of it.
-
- * Makefile: Took removal of expread.tab.c out of make clean entry
- and put it into a new "squeakyclean" entry.

-Sun Dec 11 19:40:40 1988 & Smith (randy at hobbes.ai.mit.edu)
-
- * valprint.c (val_print): Deleted spurious printing of "=" from

-
- * dbxread.c: Changed allocation of psymbols from using malloc and
- realloc to using obstacks. This means they aren't realloc'd out
- from under the pointers to them.
-
-Fri Dec 9 10:33:24 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * sparc-dep.c inflow.c core.c expread.y command.c infrun.c
- infcmd.c dbxread.c symmisc.c symtab.c printcmd.c valprint.c
- values.c source.c stack.c findvar.c breakpoint.c blockframe.c

-
- * Makefile: Cleaned up some more.
-
- * valops.c, m-*.h (FIX_CALL_DUMMY): Modified to take 5 arguments
- as per what sparc needs (programming for a superset of needed
- args).
-
- * dbxread.c (process_symbol_for_psymtab): Modified to be slightly
- more picky about what it puts on the list of things *not* to be
- put on the misc function list. When/if I shift everything over to
- being placed on the misc_function_list, this will go away.
-
- * inferior.h, infrun.c: Added fields to save in inferior_status
- structure.
-
- * maketarfile: Deleted; functionality is in Makefile now.
-
- * infrun.c (wait_for_inferior): Modified algorithm for determining
- whether or not a single-step was through a subroutine call. See
- comments at top of file.

- macro would be checked during initial readin.
-
- * dbxread.c (read_ofile_symtab): Added macro GCC_COMPILED_FLAG_SYMBOL
- into dbxread.c to indicate what string in a local text symbol will
- indicate a file compiled with gcc. Defaults to "gcc_compiled.".
-
-Thu Dec 8 11:46:22 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Cleaned up a little to take
- advantage of the new frame cache system.
-
- * inferior.h, infrun.c, valops.c, valops.c, infcmd.c: Changed
- mechanism to save inferior status over calls to inferior (eg.
- call_function); implemented save_inferior_info and

- to get_prev_frame_info.
-
- * frame.h, stack.c, printcmd.c, m-sparc.h, sparc-dep.c: Removed
- all uses of frame_id_from_addr. There are short routines like it
- still in frame_saved_pc (m-sparc.h) and parse_frame_spec

-
- * infcmd.c, sparc-dep.c: Implemented a new mechanism for
- re-selecting the selected frame on return from a call.
-
- * blockframe.c, stack.c, findvar.c, printcmd.c, m-*.h: Changed

- m-merlin.h, m-isi.h, m-i386.h, m-hp9k320.h: Changed routines to
- use "struct frame_info *" internally.
-
-Wed Dec 7 12:07:54 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * frame.h, blockframe.c, m-sparc.h, sparc-dep.c: Changed all calls
- to get_[prev_]frame_cache_item to get_[prev_]frame_info.

- get_frame_info and get_prev_frame_info.
-
- * blockframe.c: Put allocation on an obstack and eliminated fancy
- reallocation routines, several variables, and various nasty
- things.
-
- * frame.h, stack.c, infrun.c, blockframe.c, sparc-dep.c: Changed
- type FRAME to be a typedef to "struct frame_info *". Had to also
- change routines that returned frame id's to return the pointer
- instead of the cache index.
-
- * infcmd.c (finish_command): Used proper method of getting from
- function symbol to start of function. Was treating a symbol as a
- value.
-
- * blockframe.c, breakpoint.c, findvar.c, infcmd.c, stack.c,
- xgdb.c, i386-pinsn.c, frame.h, m-hp9k320.h, m-i386.h, m-isi.h,
- m-merlin.h, m-news.h, m-npl.h, m-pn.h, m-sparc.h, m-sun2.h,
- m-sun3.h, m-umax.h: Changed get_frame_info and get_prev_frame_info
- to return pointers instead of structures.
-
- * blockframe.c (get_pc_function_start): Modified to go to misc
- function table instead of bombing if pc was in a block without a
- containing function.
-
- * coffread.c: Dup'd descriptor passed to read_coff_symtab and
- fdopen'd it so that there wouldn't be multiple closes on the same
- fd. Also put (fclose, stream) on the cleanup list.
-
- * printcmd.c, stack.c: Changed print_frame_args to take a
- frame_info struct as argument instead of the address of the args
- to the frame.
-
- * m-i386.h (STORE_STRUCT_RETURN): Decremented sp by sizeof object
- to store (an address) rather than 1.
-
- * dbxread.c (read_dbx_symtab): Set first_object_file_end in
- read_dbx_symtab (oops).
-
- * coffread.c (fill_in_vptr_fieldno): Rewrote TYPE_BASECLASS as
- necessary.
-
-Tue Dec 6 13:03:43 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * coffread.c: Added fake support for partial_symtabs to allow
- compilation and execution without there use.
- * inflow.c: Added a couple of minor USG mods.
- * munch: Put in appropriate conditionals so that it would work on
- USG systems.
- * Makefile: Made regex.* handled same as obstack.*; made sure tar
- file included everything I wanted it to include (including
- malloc.c).
-
- * dbxread.c (end_psymtab): Create an entry in the
- partial_symtab_list for each subfile of the .o file just read in.
- This allows a "list expread.y:10" to work when we haven't read in
- expread.o's symbol stuff yet.
-
- * symtab.h, dbxread.c (psymtab_to_symtab): Recognize pst->ldsymlen
- == 0 as indicating a dummy psymtab, only in existence to cause the
- dependency list to be read in.
-
- * dbxread.c (sort_symtab_syms): Elminated reversal of symbols to
- make sure that register debug symbol decls always come before
- parameter symbols. After mod below, this is not needed.
-
- * symtab.c (lookup_block_symbol): Take parameter type symbols
- (LOC_ARG or LOC_REGPARM) after any other symbols which match.
-
- * dbxread.c (read_type): When defining a type in terms of some
- other type and the other type is supposed to have a pointer back
- to this specific kind of type (pointer, reference, or function),
- check to see if *that* type has been created yet. If it has, use
- it and fill in the appropriate slot with a pointer to it.
-
-Mon Dec 5 11:25:04 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * symmisc.c: Eliminated existence of free_inclink_symtabs and
- init_free_inclink_symtabs; they aren't called from anywhere, and
- if they were they could disrupt gdb's data structure badly
- (elimination of struct type's which values that stick around past
- elimination of inclink symtabs).
-
- * dbxread.c (symbol_file_command): Fixed a return pathway out of
- the routine to do_cleanups before it left.
-
- * infcmd.c (set_environment_command), gdb.texinfo: Added
- capability to set environmental variable values to null.
-
- * gdb.texinfo: Modified doc on "break" without args slightly.
-
-Sun Dec 4 17:03:16 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * dbxread.c (symbol_file_command): Added check; if there weren't
- any debugging symbols in the file just read, the user is warned.
-
- * infcmd.c: Commented set_environment_command (a little).
-
- * createtags: Cleaned up and commented.
-
- * Makefile: Updated depen_memory and write_inferior_memory in that errno is
- checked after each ptrace and returned to the caller. Used in
- value_at to detect references to addresses which are out of
- bounds. Also core.c (xfer_core_file): return 1 if invalid
- address, 0 otherwise.
-
- * inflow.c, <machine>-infdep.c: removed all calls to ptrace from
- inflo, m-sun3.h: Cleaned up dealings with
- functions returning structu0 19:19:36 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * symmisc.c: (read_symsegs) Accept only format number 2. Since
- the size of the type structure changed when C++ support was added,
- format 1 can no longer be used.
-
- * core.c, m-sunos4.h: (core_file_command) support for SunOS 4.0.
- Slight change in the core structure. #ifdef SUNOS4. New file
- m-sunos4.h. May want to change config.gdb also.
-
-Fri Jul 8 19:59:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * breakpoint.c: (break_command_1) Allow `break if condition'
- rather than parsing `if' as a function name and returning an
- error.
-
-Thu Jul 7 22:22:47 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: valops.c, valprint.c, value.h, values.c: merged code to deal
- with C++ expressions.
-
-Wed Jul 6 03:28:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches,
- add_file_command) Merged code to read symbol information from
- an incrementally linked file. symmisc.c:
- (init_free_inclink_symtabs, free_inclink_symtabs) Cleanup
- routines.
-
-Tue Jul 5 02:50:41 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: symtab.c, breakpoint.c, source.c: Merged code to deal with
- ambiguous line specifications. In C++ one can have overloaded
- function names, so that `list classname::overloadedfuncname'
- refers to several different lines, possibly sure currently configured machine
- dependent files come first in e at corn-chex.ai.mit.edu)
-
- * C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with
- a modified lookup_symbol which checks for fields of the current
- implied argument `this'. printcmd.c, source.c, symtab.c,
- valops.c: Need to change callers once callers are
- installed.
-
-Wed Jun 29 01:26:56 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
-
- * C++: eval.c, expprint.c, expread.y, expression.h, valarith.c,
- Merged code to deal with evaluation of user-defined operators,
- member functions, and virtual functions.
- binop_must_be_user_defined tests for user-defined binops,
- value_x_binop calls the appropriate operator function.
-
-Tue Jun 28 02:56:42 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
-
- * C++: Makefile: changed the echo: expect 101 shift/reduce conflicts
- and 1 reduce/reduce conflict.
-
-
-Local Variables:
-mode: indented-text
-eval: (auto-fill-mode 1)
-left-margin: 8
-fill-column: 74
-version-control: never
-End:
-
- constructors, and flags being defined via public and via
- virtual paths. Added fields NEXT_VARIANT, N_BASECLASSES,
- and BASECLASSES to this type (tr: Changed types from
- having to be derived from a single baseclass to a multiple
- base class).
- * symtab.h: Added macros to access new fields defined in symseg.h.
- Added decl for lookup_basetype_type.
- * dbxread.c
- (condense_addl_misc_bunches): Function added to condense the misc
- function bunches added by reading in a new .o file.
- (read_addl_syms): Function added to read in symbols
- from a new .o file (incremental linking).
- (add_file_command): Command interface function to indicate
- incrmental linking of a new .o file; this now calls
- read_addl_syms and condense_addl_misc_bunches.
- (define_symbol): Modified code to handle types defined from base
- types which were not known when the derived class was
- output.
- (read_struct_type): Modified to better handle description of
- struct types as derived types. Possibly derived from
- several different base classes. Also added new code to
- mark definitions via virtual paths or via public paths.
- Killed seperate code to handle classes with destructors
- but without constructors and improved marking of classes
- as having destructors and constructors.
- * infcmd.c: Modified call to val_print (one more argument).
- * symtab.c (lookup_member_type): Modified to deal with new
- structure in symseg.h.
- (lookup_basetype_type): Function added to find or construct a type
- ?derived? from the given type.
- (decode_line_1): Modified to deal with new type data structures.
- Modified to deal with new number of args for
- decode_line_2.
- (decode_line_2): Changed number of args (?why?).
- (init_type): Added inits for new C++ fields from
- symseg.h.
- *valarith.c
- (value_x_binop, value_binop): Added cases for BINOP_MIN &
- BINOP_MAX.
- * valops.c
- (value_struct_elt, check_field, value_struct_elt_for_address):
- Changed to deal with multiple possible baseclasses.
- (value_of_this): Made SELECTED_FRAME an extern variable.
- * valprint.c
- (val_print): Added an argument DEREF_REF to dereference references
- automatically, instead of printing them like pointers.
- Changed number of arguments in recursive calls to itself.
- Changed to deal with varibale numbers of base classes.
- (value_print): Changed number of arguments to val_print. Print
- type of value also if value is a reference.
- (type_print_derivation_info): Added function to print out
- derivation info a a type.
- (type_print_base): Modified to use type_print_derivation_info and
- to handle multiple baseclasses.
-
-Mon Nov 21 10:32:07 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * inflow.c (term_status_command): Add trailing newline to output.
-
- * sparc-dep.c (do_save_insn, do_restore_insn): Saved
- "stop_registers" over the call for the sake of normal_stop and
- run_stack_dummy.
-
- * m-sparc.h (EXTRACT_RETURN_VALUE): Put in parenthesis to force
- addition of 8 to the int pointer, not the char pointer.
-
- * sparc-pinsn.c (print_addr1): Believe that I have gotten the
- syntax right for loads and stores as adb does it.
-
- * symtab.c (list_symbols): Turned search for match on rexegp into
- a single loop.
-
- * dbxread.c (psymtab_to_symtab): Don't read it in if it's already
- been read in.
-
- * dbxread.c (psymtab_to_symtab): Changed error to fatal in
- psymtab_to_symtab.
-
- * expread.y (parse_number): Fixed bug which treated 'l' at end of
- number as '0'.
-
-Fri Nov 18 13:57:33 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Was
- being foolish and using pointers into an array I could realloc.
- Converted these pointers into integers.
-
-Wed Nov 16 11:43:10 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * m-sparc.h (POP_FRAME): Made the new frame be PC_ADJUST of the
- old frame.
-
- * i386-pinsn.c, m-hp9k320.h, m-isi.h, m-merlin.h, m-news.h,
- m-npl.h, m-pn.h, m-sparc.h, m-sun2.h, m-sun3.h, m-umax.h, m-vax.h:
- Modified POP_FRAME to use the current frame instead of
- read_register (FP_REGNUM) and to flush_cached_frames before
- setting the current frame. Also added a call to set the current
- frame in those POP_FRAMEs that didn't have it.
-
- * infrun.c (wait_for_inferior): Moved call to set_current_frame up
- to guarrantee that the current frame will always be set when a
- POP_FRAME is done.
-
- * infrun.c (normal_stop): Added something to reset the pc of the
- current frame (was incorrect because of DECR_PC_AFTER_BREAK).
-
- * valprint.c (val_print): Changed to check to see if a string was
- out of bounds when being printed and to indicate this if so.
-
- * convex-dep.c (read_inferior_memory): Changed to return the value
- of errno if the call failed (which will be 0 if the call
- suceeded).
-
-Tue Nov 15 10:17:15 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * infrun.c (wait_for_inferior): Two changes: 1) Added code to
- not trigger the step breakpoint on recursive calls to functions
- without frame info, and 2) Added calls to distinguish recursive
- calls within a function without a frame (which next/nexti might
- wish to step over) from jumps to the beginning of a function
- (which it generally doesn't).
-
- * m-sparc.h (INIT_EXTRA_FRAME_INFO): Bottom set correctly for leaf
- parents.
-
- * blockframe.c (get_prev_frame_cache_item): Put in mod to check
- for a leaf node (by presence or lack of function prologue). If
- there is a leaf node, it is assumed that SAVED_PC_AFTER_CALL is
- valid. Otherwise, FRAME_SAVED_PC or read_pc is used.
-
- * blockframe.c, frame.h: Did final deletion of unused routines and
- commented problems with getting a pointer into the frame cache in
- the frame_info structure comment.
-
- * blockframe.c, frame.h, stack.c: Killed use of
- frame_id_from_frame_info; used frame_id_from_addr instead.
-
- * blockframe.c, frame.h, stack.c, others (oops): Combined stack
- cache and frame info structures.
-
- * blockframe.c, sparc-dep.c, stack.c: Created the function
- create_new_frame and used it in place of bad calls to
- frame_id_from_addr.
-
- * blockframe.c, inflow.c, infrun.c, i386-pinsn.c, m-hp9k320.h,
- m-npl.h, m-pn.h, m-sparc.h, m-sun3.h, m-vax.h, default-dep.c,
- convex-dep.c, gould-dep.c, hp9k320-dep.c, news-dep.c, sparc-dep.c,
- sun3-dep.c, umax-dep.c: Killed use of
- set_current_Frame_by_address. Used set_current_frame
- (create_new_frame...) instead.
-
- * frame.h: Killed use of FRAME_FP_ID.
-
- * infrun.c, blockframe.c: Killed select_frame_by_address. Used
- select_frame (get_current_frame (), 0) (which was correct in all
- cases that we need to worry about.
-
-Mon Nov 14 14:19:32 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * frame.h, blockframe.c, stack.c, m-sparc.h, sparc-dep.c: Added
- mechanisms to deal with possible specification of frames
- dyadically.
-
-Sun Nov 13 16:03:32 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
-
- * ns32k-opcode.h: Add insns acbw, acbd.
-
-Sun Nov 13 15:09:58 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * breakpoint.c: Changed breakpoint structure to use the address of
- a given frame (constant across inferior runs) as the criteria for
- stopping instead of the frame ident (which varies across inferior
- calls).
-
-Fri Nov 11 13:00:22 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * gld-pinsn.c (findframe): Modified to work with the new frame
- id's. Actually, it looks as if this routine should be called with
- an address anyway.
-
- * findvar.c (find_saved_register): Altered bactrace loop to work
- off of frames and not frame infos.
-
- * frame.h, blockframe.c, stack.c, sparc-dep.c, m-sparc.h: Changed
- FRAME from being the address of the frame to being a simple ident
- which is an index into the frame_cache_item list.
- * convex-dep.c, default-dep.c, gould-dep.c, hp9k320-dep.c,
- i386-pinsn.c, inflow.c, infrun.c, news-dep.c, sparc-dep.c,
- sun3-dep.c, umax-dep.c, m-hp9k320.h, m-npl.h, m-pn.h, m-sparc.h,
- m-sun3.h, m-vax.h: Changed calls of the form set_current_frame
- (read_register (FP_REGNUM)) to set_current_frame_by_address (...).
-
-Thu Nov 10 16:57:57 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * frame.h, blockframe.c, gld-pinsn.c, sparc-dep.c, stack.c,
- infrun.c, findvar.c, m-sparc.h: Changed the FRAME type to be
- purely an identifier, using FRAME_FP and FRAME_FP_ID to convert
- back and forth between the two. The identifier is *currently*
- still the frame pointer value for that frame.
-
-Wed Nov 9 17:28:14 1988 Chris Hanson (cph at kleph)
-
- * m-hp9k320.h (FP_REGISTER_ADDR): Redefine this to return
- difference between address of given FP register, and beginning of
- `struct user' that it occurs in.
-
- * hp9k320-dep.c (core_file_command): Fix sign error in size
- argument to myread. Change buffer argument to pointer; was
- copying entire structure.
- (fetch_inferior_registers, store_inferior_registers): Replace
- occurrences of `FP_REGISTER_ADDR_DIFF' with `FP_REGISTER_ADDR'.
- Flush former definition.
-
-Wed Nov 9 12:11:37 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * xgdb.c: Killed include of initialize.h.
-
- * Pulled in xgdb.c from the net.
-
- * Checkpointed distribution (to provide to 3b2 guy).
-
- * coffread.c, dbxread.c, symmisc.c, symtab.c, symseg.h: Changed
- format of table of line number--pc mapping information. Can
- handle negative pc's now.
-
- * command.c: Deleted local copy of savestring; code in utils.c is
- identical.
-
-Tue Nov 8 11:12:16 1988 Randall Smith (randy at plantaris.ai.mit.edu)
-
- * gdb.texinfo: Added documentation for shell escape.
-
-Mon Nov 7 12:27:16 1988 Randall Smith (randy at sugar-bombs.ai.mit.edu)
-
- * command.c: Added commands for shell escape.
-
- * core.c, dbxread.c: Added ROBOTUSSIN mods.
-
- * Checkpointed distribution.
-
- * printcmd.c (x_command): Yanked error if there is no memory to
- examine (could be looking at executable straight).
-
- * sparc-pinsn.c (print_insn): Amount to leftshift sethi imm by is
- now 10 (matches adb in output).
-
- * printcmd.c (x_command): Don't attempt to set $_ & $__ if there
- is no last_examine_value (can happen if you did an x/0).
-
-Fri Nov 4 13:44:49 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * printcmd.c (x_command): Error if there is no memory to examine.
-
- * gdb.texinfo: Added "cont" to the command index.
-
- * sparc-dep.c (do_save_insn): Fixed typo in shift amount.
-
- * m68k-opcode.h: Fixed opcodes for 68881.
-
- * breakpoint.c, infcmd.c, source.c: Changed defaults in several
- places for decode_line_1 to work off of the default_breakpoint_*
- values instead of current_source_* values (the current_source_*
- values are off by 5 or so because of listing defaults).
-
- * stack.c (frame_info): ifdef'd out FRAME_SPECIFCATION_DYADIC in
- the stack.c module. If I can't do this right, I don't want to do
- it at all. Read the comment there for more info.
-
-Mon Oct 31 16:23:06 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * gdb.texinfo: Added documentation on the "until" command.
-
-Sat Oct 29 17:47:10 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * breakpoint.c, infcmd.c: Added UNTIL_COMMAND and subroutines of
- it.
-
- * breakpoint.c, infcmd.c, infrun.c: Added new field to breakpoint
- structure (silent, indicating a silent breakpoint), and modified
- breakpoint_stop_status and things that read it's return value to
- understand it.
-
-Fri Oct 28 17:45:33 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * dbxread.c, symmisc.c: Assorted speedups for readin, including
- special casing most common symbols, and doing buffering instead of
- calling malloc.
-
-Thu Oct 27 11:11:15 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * stack.c, sparc-dep.c, m-sparc.h: Modified to allow "info frame"
- to take two arguments on the sparc and do the right thing with
- them.
-
- * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
- stuff to put only symbols that didn't have debugging info on the
- misc functions list back in.
-
-Wed Oct 26 10:10:32 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * valprint.c (type_print_varspec_suffix): Added check for
- TYPE_LENGTH(TYPE_TARGET_TYPE(type)) > 0 to prevent divide by 0.
-
- * printcmd.c (print_formatted): Added check for VALUE_REPEATED;
- value_print needs to be called for that.
-
- * infrun.c (wait_for_inferior): Added break when you decide to
- stop on a null function prologue rather than continue stepping.
-
- * m-sun3.h: Added explanatory comment to REGISTER_RAW_SIZE.
-
- * expread.y (parse_c_1): Initialized paren_depth for each parse.
-
-Tue Oct 25 14:19:38 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * valprint.c, coffread.c, dbxread.c: Enum constant values in enum
- type now accessed through TYPE_FIELD_BITPOS.
-
- * dbxread.c (process_symbol_for_psymtab): Added code to deal with
- possible lack of a ":" in a debugging symbol (do nothing).
-
- * symtab.c (decode_line_1): Added check in case of all numbers for
- complete lack of symbols.
-
- * source.c (select_source_symtab): Made sure that this wouldn't
- bomb on complete lack of symbols.
-
-Mon Oct 24 12:28:29 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * m-sparc.h, findvar.c: Ditched REGISTER_SAVED_UNIQUELY and based
- code on REGISTER_IN_WINDOW_P and HAVE_REGISTER_WINDOWS. This will
- break when we find a register window machine which saves the
- window registers within the context of an inferior frame.
-
- * sparc-dep.c (frame_saved_pc): Put PC_ADJUST return back in for
- frame_saved_pc. Seems correct.
-
- * findvar.c, m-sparc.h: Created the macro REGISTER_SAVED_UNIQUELY
- to handle register window issues (ie. that find_saved_register
- wasn't checking the selected frame itself for shit).
-
- * sparc-dep.c (core_file_command): Offset target of o & g register
- bcopy by 1 to hit correct registers.
-
- * m-sparc.h: Changed STACK_END_ADDR.
-
-Sun Oct 23 19:41:51 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * sparc-dep.c (core_file_command): Added in code to get the i & l
- registers from the stack in the corefile, and blew away some wrong
- code to get i & l from inferior.
-
-Fri Oct 21 15:09:19 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu)
-
- * m-sparc.h (PUSH_DUMMY_FRAME): Saved the value of the RP register
- in the location reserved for i7 (in the created frame); this way
- the rp value won't get lost. The pc (what we put into the rp in
- this routine) gets saved seperately, so we loose no information.
-
- * sparc-dep.c (do_save_insn & do_restore_insn): Added a wrapper to
- preserve the proceed status state variables around each call to
- proceed (the current frame was getting munged because this wasn't
- being done).
-
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Fix bug: saved registers
- addresses were being computed using absolute registers number,
- rather than numbers relative to each group of regs.
-
- * m-sparc.h (POP_FRAME): Fixed a bug (I hope) in the context
- within which saved reg numbers were being interpetted. The
- values to be restored were being gotten in the inferior frame, and
- the restoring was done in the superior frame. This means that i
- registers must be restored into o registers.
-
- * sparc-dep.c (do_restore_insn): Modified to take a pc as an
- argument, instead of a raw_buffer. This matches (at least it
- appears to match) usage from POP_FRAME, which is the only place
- from which do_restore_insn is called.
-
- * sparc-dep.c (do_save_insn and do_restore_insn): Added comments.
-
- * m-sparc.h (FRAME_FIND_SAVED_REGS): Modified my code to find the
- save addresses of out registers to use the in regs off the stack
- pointer when the current frame is 1 from the innermost.
-
-Thu Oct 20 13:56:15 1988 & Smith (randy at hobbes.ai.mit.edu)
-
- * blockframe.c, m-sparc.h: Removed code associated with
- GET_PREV_FRAME_FROM_CACHE_ITEM. This code was not needed for the
- sparc; you can always find the previous frames fp from the fp of
- the current frame (which is the sp of the previous). It's getting
- the information associated with a given frame (ie. saved
- registers) that's a bitch, because that stuff is saved relative to
- the stack pointer rather than the frame pointer.
-
- * m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return
- the frame pointer of the previous frame instead of the stack
- pointer of same.
-
- * blockframe.c (flush_cached_frames): Modified call to
- obstack_free to free back to frame_cache instead of back to zero.
- This leaves the obstack control structure in finite state (and
- still frees the entry allocated at frame_cache).
-
-Sat Oct 15 16:30:47 1988 & Smith (randy at tartarus.uchicago.edu)
-
- * valops.c (call_function): Suicide material here. Fixed a typo;
- CALL_DUMMY_STACK_ADJUST was spelled CAll_DUMMY_STACK_ADJUST on
- line 530 of the file. This cost me three days. I'm giving up
- typing for lent.
-
-Fri Oct 14 15:10:43 1988 & Smith (randy at tartarus.uchicago.edu)
-
- * m-sparc.h: Corrected a minor mistake in the dummy frame code
- that was getting the 5th argument and the first argument from the
- same place.
-
-Tue Oct 11 11:49:33 1988 & Smith (randy at tartarus.uchicago.edu)
-
- * infrun.c: Made stop_after_trap and stop_after_attach extern
- instead of static so that code which used proceed from machine
- dependent files could fiddle with them.
-
- * blockframe.c, frame.h, sparc-dep.c, m-sparc.h: Changed sense of
- ->prev and ->next in struct frame_cache_item to fit usage in rest
- of gdb (oops).
-
-Mon Oct 10 15:32:42 1988 Randy Smith (randy at gargoyle.uchicago.edu)
-
- * m-sparc.h, sparc-dep.c, blockframe.c, frame.h: Wrote
- get_frame_cache_item. Modified FRAME_SAVED_PC and frame_saved_pc
- to take only one argument and do the correct thing with it. Added
- the two macros I recently defined in blockframe.c to m-sparc.h.
- Have yet to compile this thing on a sparc, but I've now merged in
- everything that I received from tiemann, either exactly, or simply
- effectively.
-
- * source.c: Added code to allocated space to sals.sals in the case
- where no line was specified.
-
- * blockframe.c, infrun.c: Modified to cache stack frames requested
- to minimize accesses to subprocess.
-
-Tue Oct 4 15:10:39 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
-
- * config.gdb: Added sparc.
-
-Mon Oct 3 23:01:22 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
-
- * Makefile, blockframe.c, command.c, core.c, dbxread.c, defs.h,
- expread.y, findvar.c, infcmd.c, inflow.c, infrun.c, sparc-pinsn.c,
- m-sparc.h, sparc-def.c, printcmd.c, stack.c, symmisc.c, symseg.h,
- valops.c, values.c: Did initial merge of sparc port. This will
- not compile; have to do stack frame caching and finish port.
-
- * inflow.c, gdb.texinfo: `tty' now resets the controling terminal.
-
-Fri Sep 30 11:31:16 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * inferior.h, infcmd.c, infrun.c: Changed the variable
- stop_random_signal to stopped_by_random signal to fit in better
- with name conventions (variable is not a direction to the
- proceed/resume set; it is information from it).
-
-Thu Sep 29 13:30:46 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
-
- * infcmd.c (finish_command): Value type of return value is now
- whatever the function returns, not the type of the function (fixed
- a bug in printing said value).
-
- * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab):
- Put *all* global symbols into misc_functions. This is what was
- happening anyway, and we need it for find_pc_misc_function.
-
- ** This was eventually taken out, but I didn't mark it in the
- ChangeLog. Oops.
-
- * dbxread.c (process_symbol_for_psymtab): Put every debugger
- symbol which survives the top case except for constants on the
- symchain. This means that all of these *won't* show up in misc
- functions (this will be fixed once I make sure it's broken the way
- it's supposed to be).
-
- * dbxread.c: Modified placement of debugger globals onto the hash
- list; now we exclude the stuff after the colon and don't skip the
- first character (debugger symbols don't have underscores).
-
- * dbxread.c: Killed debuginfo stuff with ifdef's.
-
-Wed Sep 28 14:31:51 1988 Randall Smith (randy at cream-of-wheat.ai.mit.edu)
-
- * symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and
- EXCL symbols produced by the sun loader by adding a list of
- pre-requisite partial_symtabs that each partial symtab needs.
-
- * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid
- doing a qsort on the local (static) psymbols for each file to
- speed startup. This feature is not completely debugged, but it's
- inclusion has forced the inclusion of another feature (dealing
- with EINCL's, BINCL's and EXCL's) and so I'm going to go in and
- deal with them.
-
- * dbxread.c (process_symbol_for_psymtab): Made sure that the class
- of the symbol made it into the partial_symbol entry.
-
-Tue Sep 27 15:10:26 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * dbxread.c: Fixed bug; init_psymbol_list was not being called
- with the right number of arguments (1).
-
- * dbxread.c: Put ifdef's around N_MAIN, N_M2C, and N_SCOPE to
- allow compilation on a microvax.
-
- * config.gdb: Modified so that "config.gdb vax" would work.
-
- * dbxread.c, symtab.h, symmisc.h, symtab.c, source.c: Put in many
- and varied hacks to speed up gdb startup including: A complete
- rewrite of read_dbx_symtab, a modification of the partial_symtab
- data type, deletion of select_source_symtab from
- symbol_file_command, and optimiztion of the call to strcmp in
- compare_psymbols.
-
-Thu Sep 22 11:08:54 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * dbxread.c (psymtab_to_symtab): Removed call to
- init_misc_functions.
-
- * dbxread.c: Fixed enumeration type clash (used enum instead of
- integer constant).
-
- * breakpoint.c: Fixed typo; lack of \ at end of line in middle of
- string constant.
-
- * symseg.h: Fixed typo; lack of semicolon after structure
- definition.
-
- * command.c, breakpoint.c, printcmd.c: Added cmdlist editing
- functions to add commands with the abbrev flag set. Changed
- help_cmd_list to recognize this flag and modified unset,
- undisplay, and enable, disable, and delete breakpoints to have
- this flag set.
-
-Wed Sep 21 13:34:19 1988 Randall Smith (randy at plantaris.ai.mit.edu)
-
- * breakpoint.c, infcmd.c, gdb.texinfo: Created "unset" as an alias
- for delete, and changed "unset-environment" to be the
- "environment" subcommand of "delete".
-
- * gdb.texinfo, valprint.c: Added documentation in the manual for
- breaking the set-* commands into subcommands of set. Changed "set
- maximum" to "set array-max".
-
- * main.c, printcmd.c, breakpoint.c: Moved the declaration of
- command lists into main and setup a function in main initializing
- them to guarrantee that they would be initialized before calling
- any of the individual files initialize routines.
-
- * command.c (lookup_cmd): A null string subcommand is treated as
- an unknown subcommand rather than an ambiguous one (eg. "set $x =
- 1" will now work).
-
- * infrun.c (wait_for_inferior): Put in ifdef for Sony News in
- check for trap by INNER_THAN macro.
-
- * eval.c (evaluate_subexp): Put in catch to keep the user from
- attempting to call a non function as a function.
-
-Tue Sep 20 10:35:53 1988 Randall Smith (randy at oatmeal.ai.mit.edu)
-
- * dbxread.c (read_dbx_symtab): Installed code to keep track of
- which global symbols did not have debugger symbols refering to
- them, and recording these via record_misc_function.
-
- * dbxread.c: Killed code to check for extra global symbols in the
- debugger symbol table.
-
- * printcmd.c, breakpoint.c: Modified help entries for several
- commands to make sure that abbreviations were clearly marked and
- that the right commands showed up in the help listings.
-
- * main.c, command.c, breakpoint.c, infcmd.c, printcmd.c,
- valprint.c, defs.h: Modified help system to allow help on a class
- name to show subcommands as well as commands and help on a command
- to show *all* subcommands of that command.
-
-Fri Sep 16 16:51:19 1988 Randall Smith (randy at gluteus.ai.mit.edu)
-
- * breakpoint.c (_initialize_breakpoint): Made "breakpoints"
- subcommands of enable, disable, and delete use class 0 (ie. they
- show up when you do a help xxx now).
-
- * infcmd.c,printcmd,c,main.c,valprint.c: Changed the set-*
- commands into subcommands of set. Created "set variable" for use
- with variables whose names might conflict with other subcommands.
-
- * blockframe.c, dbxread.c, coffread.c, expread.y, source.c:
- Fixed mostly minor (and one major one in block_for_pc) bugs
- involving checking the partial_symtab_list when a scan through the
- symtab_list fails.
-
-Wed Sep 14 12:02:05 1988 Randall Smith (randy at sugar-smacks.ai.mit.edu)
-
- * breakpoint.c, gdb.texinfo: Added enable breakpoints, disable
- breakpoints and delete breakpoints as synonyms for enable,
- disable, and delete. This seemed reasonable because of the
- immeninent arrival of watchpoints & etc.
-
- * gdb.texinfo: Added enable display, disable display, and delete
- display to manual.
-
-Tue Sep 13 16:53:56 1988 Randall Smith (randy at sugar-smacks.ai.mit.edu)
-
- * inferior.h, infrun.c, infcmd.c: Added variable
- stop_random_signal to indicate when a proceed had been stopped by
- an unexpected signal. Used this to determine (in normal_stop)
- whether the current display point should be deleted.
-
- * valops.c: Fix to value_ind to check for reference before doing a
- COERCE_ARRAY.
-
-Sun Jul 31 11:42:36 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
-
- * breakpoint.c (_initialize_breakpoint): Clean up doc for commands
- that can now apply also to auto-displays.
-
- * coffread.c (record_line): Corrected a spazz in editing.
- Also removed the two lines that assume line-numbers appear
- only in increasing order.
-
-Tue Jul 26 22:19:06 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * expression.h, eval.c, expprint.c, printcmd.c, valarith.c,
- valops.c, valprint.c, values.c, m-*.h: Changes for evaluating and
- displaying 64-bit `long long' integers. Each machine must define
- a LONGEST type, and a BUILTIN_TYPE_LONGEST.
-
- * symmisc.c: (print_symtab) check the status of the fopen and call
- perror_with_name if needed.
-
-Thu Jul 21 00:56:11 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * Convex: core.c: changes required by Convex's SOFF format were
- isolated in convex-dep.c.
-
-Wed Jul 20 21:26:10 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * coffread.c, core.c, expread.y, i386-pinsn.c, infcmd.c, inflow.c,
- infrun.c, m-i386.h, main.c, remote.c, source.c, valops.c:
- Improvements for the handling of the i386 and other machines
- running USG. (Several of these files just needed extra header files
- such as types.h.) utils.c: added bcopy, bcmp, bzero, getwd, list
- of signals, and queue routines for USG systems. Added vfork macro
- to i386
-
- * printcmd.c, breakpoint.c: New commands to enable/disable
- auto-displays. Also `delete display displaynumber' works like
- `undisplay displaynumber'.
-
-Tue Jul 19 02:17:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * coffread.c: (coff_lookup_type) Wrong portion of type_vector was
- being bzero'd after type_vector was reallocated.
-
- * printcmd.c: (delete_display) Check for a display chain before
- attempting to delete a display.
-
- * core.c, *-dep.c (*-infdep moved to *-dep): machine-dependent
- parts of core.c (core_file_command, exec_file_command) moved to
- *-dep.c.
-
-Mon Jul 18 19:45:51 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * dbxread.c: typo in read_struct_type (missing '=') was causing a
- C struct to be parsed as a C++ struct, resulting in a `invalid
- character' message.
-
-Sun Jul 17 22:27:32 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * printcmd.c, symtab.c, valops.c, expread.y: When an expression is
- read, the innermost block required to evaluate the expression is
- saved in the global variable `innermost_block'. This information
- is saved in the `block' field of an auto-display so that
- expressions with inactive variables can be skipped. `info display'
- tells the user which displays are active and which are not. New
- fn `contained_in' returns nonzero if one block is contained within
- another.
-
-Fri Jul 15 01:53:14 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * infrun.c, m-i386.h: Use macro TRAPS_EXPECTED to set number of
- traps to skip when sh execs the program. Default is 2, m-i386.h
- overrides this and sets to 4.
-
- * coffread.c, infrun.c: minor changes for the i386. May be able
- to eliminate them with more general code.
-
- * default-infdep.c: #ifdef SYSTEMV, include header file types.h.
- Also switched the order of signal.h and user.h, since System 5
- requires signal.h to come first.
-
- * core.c main.c, remote,c, source.c, inflow.c: #ifdef SYSTEMV,
- include various header files. Usually types.h and fcntl.h.
-
- * utils.c: added queue routines needed by the i386 (and other sys
- 5 machines).
-
- * sys5.c, regex.c, regex.h: new files for sys 5 systems. (The
- regex files are simply links to /gp/gnu/lib.)
-
-Thu Jul 14 01:47:14 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * config.gdb, README: Provide a list of known machines when user
- enters an invalid machine. New second arg is operating system,
- currently only used with `sunos4' or `os4'. Entry for i386 added.
-
- * news-infdep.c: new file.
-
- * m-news.h: new version which deals with new bugs in news800's OS.
-
-Tue Jul 12 19:52:16 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * Makefile, *.c, munch, config.gdb, README: New initialization
- scheme uses nm to find functions whose names begin with
- `_initialize_'. Files `initialize.h', `firstfile.c',
- `lastfile.c', `m-*init.h' no longer needed.
-
- * eval.c, symtab.c, valarith.c, valops.c, value.h, values.c: Bug
- fixes from gdb+ 2.5.4. evaluate_subexp takes a new arg, type
- expected. New fn value_virtual_fn_field.
-
-Mon Jul 11 00:48:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * core.c (read_memory): xfer_core_file was being called with an
- extra argument (0) by read_memory.
-
- * core.c (read_memory), *-infdep.c (read_inferior_memory),
- valops.c (value_at): read_memory and read_inferior_memory now work
- like write_memory and write_inferior_memory in that errno is
- checked after each ptrace and returned to the caller. Used in
- value_at to detect references to addresses which are out of
- bounds. Also core.c (xfer_core_file): return 1 if invalid
- address, 0 otherwise.
-
- * inflow.c, <machine>-infdep.c: removed all calls to ptrace from
- inflow.c and put them in machine-dependent files *-infdep.c.
-
-Sun Jul 10 19:19:36 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * symmisc.c: (read_symsegs) Accept only format number 2. Since
- the size of the type structure changed when C++ support was added,
- format 1 can no longer be used.
-
- * core.c, m-sunos4.h: (core_file_command) support for SunOS 4.0.
- Slight change in the core structure. #ifdef SUNOS4. New file
- m-sunos4.h. May want to change config.gdb also.
-
-Fri Jul 8 19:59:49 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * breakpoint.c: (break_command_1) Allow `break if condition'
- rather than parsing `if' as a function name and returning an
- error.
-
-Thu Jul 7 22:22:47 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: valops.c, valprint.c, value.h, values.c: merged code to deal
- with C++ expressions.
-
-Wed Jul 6 03:28:18 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches,
- add_file_command) Merged code to read symbol information from
- an incrementally linked file. symmisc.c:
- (init_free_inclink_symtabs, free_inclink_symtabs) Cleanup
- routines.
-
-Tue Jul 5 02:50:41 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: symtab.c, breakpoint.c, source.c: Merged code to deal with
- ambiguous line specifications. In C++ one can have overloaded
- function names, so that `list classname::overloadedfuncname'
- refers to several different lines, possibly in different files.
-
-Fri Jul 1 02:44:20 1988 Peter TerMaat (pete at corn-chex.ai.mit.edu)
-
- * C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with
- a modified lookup_symbol which checks for fields of the current
- implied argument `this'. printcmd.c, source.c, symtab.c,
- valops.c: Need to change callers once callers are
- installed.
-
-Wed Jun 29 01:26:56 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
-
- * C++: eval.c, expprint.c, expread.y, expression.h, valarith.c,
- Merged code to deal with evaluation of user-defined operators,
- member functions, and virtual functions.
- binop_must_be_user_defined tests for user-defined binops,
- value_x_binop calls the appropriate operator function.
-
-Tue Jun 28 02:56:42 1988 Peter TerMaat (pete at frosted-flakes.ai.mit.edu)
-
- * C++: Makefile: changed the echo: expect 101 shift/reduce conflicts
- and 1 reduce/reduce conflict.

- Suggested projects for aspiring or current GDB hackers
- ======================================================
-
- (You should probably chat with kingdon@ai.mit.edu to make sure that
- no one else is doing the project you chose).
-
-Add watchpoints (break if a memory location changes). This would
-usually have to involve constant single stepping, but occasionally
-there is operating system support which gdb should be able to cleanly
-use (e.g. on the 80386, there are 4 debug registers. By ptracing an
-address into them, you can get a trap on writes or on reads and
-writes).
-
-Rewrite proceed, wait_for_inferior, and normal_stop to clean them up.
-Suggestions:
-
- 1) Make each test in wait_for_inferior a seperate subroutine
- call.
- 2) Combine wait_for_inferior and normal_stop to clean up
- communication via global variables.
- 3) See if you can find some way to clean up the global
- variables that are used; possibly group them by data flow
- and information content?
-
-Work out some kind of way to allow running the inferior to be done as
-a sub-execution of, eg. breakpoint command lists. Currently running
-the inferior interupts any command list execution. This would require
-some rewriting of wait_for_inferior & friends, and hence should
-probably be done in concert with the above.
-
-Add function arguments to gdb user defined functions.
-
-Add convenience variables that refer to exec file, symbol file,
-selected frame source file, selected frame function, selected frame
-line number, etc.
-
-Add a "suspend" subcommand of the "continue" command to suspend gdb
-while continuing execution of the subprocess. Useful when you are
-debugging servers and you want to dodge out and initiate a connection
-to a server running under gdb.
-
-Make "handle" understand symbolic signal names.
-
-Work out and implement a reasonably general mechanism for multi-threaded
-processies. There are parts of one implemented in convex-dep.c, if
-you want an example.
-
-A standalone version of gdb on the i386 exists. Anyone who wants to
-do some serious working cleaning it up and making it a general
-standalone gdb should contact pace@wheaties.ai.mit.edu.
-
-Add stab information to allow reasonable debugging of inline functions
-(possibly they should show up on a stack backtrace? With a note
-indicating that they weren't "real"?).
-
-Implement support for specifying arbitrary locations of stack frames
-(in practice, this usually requires specification of both the top and
-bottom of the stack frame (fp and sp), since you *must* retrieve the
-pc that was saved in the innermost frame).
-
-Modify the naked "until" command to step until past the current source
-line, rather than past the current pc value. This is tricky simply
-because the low level routines have no way of specifying a multi-line
-step range, and there is no way of saying "don't print stuff when we
-stop" from above (otherwise could just call step many times).
-
-Modify the handling of symbols grouped through BINCL/EINCL stabs to
-allocate a partial symtab for each BINCL/EINCL grouping. This will
-seriously decrease the size of inter-psymtab dependencies and hence
-lessen the amount that needs to be read in when a new source file is
-accessed.
-
-Work out some method of saving breakpoints across the reloading of an
-executable. Probably this should be by saving the commands by which
-the breakpoints were set and re-executing them (as text locations may
-change).
-
-Do an "x/i $pc" after each stepi or nexti.
-
-Modify all of the disassemblers to use printf_filtered to get correct
-more filtering.
-
-Modify gdb to work correctly with Pascal.
-
-Rewrite macros that handle frame chaining and frameless functions.
-They should be able to tell the difference between start, main, and a
-frameless function called from main.
-
-Work out what information would need to be included in an executable
-by the compiler to allow gdb to debug functions which do not have a
-frame pointer. Modify gdb and gcc to do this.
-
-When `attached' to a program (via either OS support or remote
-debugging), gdb should arrange to catch signals which the terminal
-might send, as it is unlikely that the program will be able to notice
-them. SIGINT and SIGTSTP are obvious examples.
-
-Enhance the gdb manual with extra examples where needed.
-
-Arrange for list_command not to use decode_line_1 and thus not require
-symbols to be read in simply to read a source file.
-
-Problem in xgdb; the readline library needs the terminal in CBREAK
-mode for command line editing, but this makes it difficult to dispatch
-on button presses. Possible solution: use a define to replace getc in
-readline.c with a routine that does button dispatches. You should
-probably see XGDB-README before you fiddle with XGDB. Also, someone
-is implementing a new xgdb; it may not be worth while fiddling with
-the old one.

-This is GDB, the GNU source-level debugger, presently running under un*x.
-
-Before compiling GDB, you must tell GDB what kind of machine you are
-running on. To do this, type `config.gdb machine', where machine is
-something like `vax' or `sun2'. For a list of valid machine types,
-type `config.gdb'.
-
-Normally config.gdb edits the makefile as necessary. If you have to
-edit the makefile on a standard machine listed in config.gdb this
-should be considered a bug and reported as such.
-
-Once these files are set up, just `make' will do everything,
-producing an executable `gdb' in this directory.
-
-If you want a new (current to this release) version of the manual, you
-will have to use the gdb.texinfo file provided with this distribution.
-The gdb.texinfo file requires the texinfo-format-buffer command from
-emacs 18.55 or later.
-
-About languages other than C...
-
-C++ support has been integrated into gdb. GDB should work with
-FORTRAN programs (if you have problem, please send a bug report), but
-I am not aware of anyone who is working on getting it to use the
-syntax of any language other than C or C++. Pascal programs which use
-sets, subranges, file variables, or nested functions will not
-currently work.
-
-About -gg format...
-
-Currently GDB version 3.x does *not* support GCC's -gg format. This
-is because it (in theory) has fast enough startup on dbx debugging
-format object files that -gg format is unnecessary (and hence
-undesirable, since it wastes space and processing power in gcc). I
-would like to hear people's opinions on the amount of time currently
-spent in startup; is it fast enough?
-
-About remote debugging...
-
-The two files remote-multi.shar and remote-sa.m68k.shar contain two
-examples of a remote stub to be used with remote.c. The the -multi
-file is a general stub that can probably be running on various
-different flavors of unix to allow debugging over a serial line from
-one machine to another. The remote-sa.m68k.shar is designed to run
-standalone on a 68k type cpu and communicate properley with the
-remote.c stub over a serial line.
-
-About reporting bugs...
-
-The correct address for reporting bugs found with gdb is
-"bug-gdb@prep.ai.mit.edu". Please send all bugs to that address.
-
-About xgdb...
-
-xgdb.c was provided to us by the user community; it is not an integral
-part of the gdb distribution. The problem of providing visual
-debugging support on top of gdb is peripheral to the GNU project and
-(at least right now) we can't afford to put time into it. So while we
-will be happy to incorporate user fixes to xgdb.c, we do not guarantee
-that it will work and we will not fix bugs reported in it. Someone is
-working on writing a new XGDB, so improving (e.g. by fixing it so that
-it will work, if it doesn't currently) the current one is not worth it.
-
-For those intersted in auto display of source and the availability of
-an editor while debugging I suggest trying gdb-mode in gnu-emacs.
-Comments on this mode are welcome.
-
-About the machine-dependent files...
-
-m-<machine>.h (param.h is a link to this file).
-This file contains macro definitions that express information
-about the machine's registers, stack frame format and instructions.
-
-<machine>-opcode.h (opcode.h is a link to this file).
-<machine>-pinsn.c (pinsn.c is a link to this file).
-These files contain the information necessary to print instructions
-for your cpu type.
-
-<machine>-dep.c (dep.c is a link to this file).
-Those routines which provide a low level interface to ptrace and which
-tend to be machine-dependent. (The machine-independent routines are in
-`infrun.c' and `inflow.c')
-
-About writing code for GDB...
-
-We appreciate having users contribute code that is of general use, but
-for it to be included in future GDB releases it must be cleanly
-written. We do not want to include changes that will needlessly make future
-maintainance difficult. It is not much harder to do things right, and
-in the long term it is worth it to the GNU project, and probably to
-you individually as well.
-
-Please code according to the GNU coding standards. If you do not have
-a copy, you can request one by sending mail to gnu@prep.ai.mit.edu.
-
-Please try to avoid making machine-specific changes to
-machine-independent files (i.e. all files except "param.h" and
-"dep.c". "pinsn.c" and "opcode.h" are processor-specific but not
-operating system-dependent). If this is unavoidable, put a hook in
-the machine-independent file which calls a (possibly)
-machine-dependent macro (for example, the IGNORE_SYMBOL macro can be
-used for any symbols which need to be ignored on a specific machine.
-Calling IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of #if
-defined's). The machine-independent code should do whatever "most"
-machines want if the macro is not defined in param.h. Using #if
-defined can sometimes be OK (e.g. SET_STACK_LIMIT_HUGE) but should be
-conditionalized on a specific feature of an operating system (set in
-param.h) rather than something like #if defined(vax) or #if
-defined(SYSV).
-
-It is better to replace entire routines which may be system-specific,
-rather than put in a whole bunch of hooks which are probably not going
-to be helpful for any purpose other than your changes. For example,
-if you want to modify dbxread.c to deal with DBX debugging symbols
-which are in COFF files rather than BSD a.out files, do something
-along the lines of a macro GET_NEXT_SYMBOL, which could have
-different definitions for COFF and a.out, rather than trying to put
-the necessary changes throughout all the code in dbxread.c that
-currently assumes BSD format.
-
-Please avoid duplicating code. For example, if something needs to be
-changed in read_inferior_memory, it is very painful because there is a
-copy in every dep.c file. The correct way to do this is to put (in
-this case) the standard ptrace interfaces in a separate file ptrace.c,
-which is used by all systems which have ptrace. ptrace.c would deal
-with variations between systems the same way any system-independent
-file would (hooks, #if defined, etc.).
-
-About debugging gdb with itself...
-
-You probably want to do a "make TAGS" after you configure your
-distribution; this will put the machine dependent routines for your
-local machine where they will be accessed first by a M-period .
-
-Also, make sure that you've compiled gdb with your local cc or taken
-appropriate precautions regarding ansification of include files. See
-the Makefile for more information.
-
-The "info" command, when executed without a subcommand in a gdb being
-debugged by gdb, will pop you back up to the top level gdb. See
-.gdbinit for more details.

- a better name..
-
- Anyway, a seclet contains enough info to be able to describe an
- area of output memory in one go.
-
- The only description so far catered for is that of the
- <<bfd_indirect_seclet>>, which is a select which points to a
- <<section>> and the <<asymbols>> associated with the section, so
- that relocation can be done when needed.
-
- One day there will be more types - they will at least migrate from
- the linker's data structures - also there could be extra stuff,
- like a bss seclet, which descibes a lump of memory as containing
- zeros compactly, without the horrible SEC_* flag cruft.

-
- The generic seclet linking routine. The caller should have

- should point to a memory area large enough to hold the largest
- section. This function looks through the seclets and moves
- the contents into the output sections. If RELOCATEABLE is
- true, the orelocation fields of the output sections must
- already be initialized.

- is no practical difference between an int and a short
- (except perhaps what happens when the GDB user types
- "print short_arg = 0x10000;").
- Hacked for SunOS 4.1 by gnu@cygnus.com. In 4.1, the compiler
- actually produces the correct address (we don't need to fix it

-Summary of GDB
-**************
-
- The purpose of a debugger such as GDB is to allow you to see what is
-going on "inside" another program while it executes--or what another
-program was doing at the moment it crashed.
-
- GDB can do four main kinds of things (plus other things in support of
-these) to help you catch bugs in the act:
-
- * Start your program, specifying anything that might affect its
- behavior.
-
- * Make your program stop on specified conditions.
-
- * Examine what has happened, when your program has stopped.
-
- * Change things in your program, so you can experiment with
- correcting the effects of one bug and go on to learn about another.
-
- You can use GDB to debug programs written in C, C++, and Modula-2.
-G{No Value For "DBN"} can be used to debug programs written in Fortran,
-although it does not yet support entering expressions, printing values,
-etc. using Fortran syntax. It may be necessary to refer to some
-variables with a trailing underscore.

-Free software
-=============
-
- GDB is "free software", protected by the GNU General Public License
-(GPL). The GPL gives you the freedom to copy or adapt a licensed
-program--but every person getting a copy also gets with it the freedom
-to modify that copy (which means that they must get access to the
-source code), and the freedom to distribute further copies. Typical
-software companies use copyrights to limit your freedoms; the Free
-Software Foundation uses the GPL to preserve these freedoms.
-
- Fundamentally, the General Public License is a license which says
-that you have these freedoms and that you cannot take these freedoms
-away from anyone else.
-
-
-File: gdb.info, Node: Contributors, Prev: Free Software, Up: Summary
-
-Contributors to GDB
-===================
-
- Richard Stallman was the original author of GDB, and of many other
-GNU programs. Many others have contributed to its development. This
-section attempts to credit major contributors. One of the virtues of
-free software is that everyone is free to contribute to it; with
-regret, we cannot actually acknowledge everyone here. The file
-`ChangeLog' in the GDB distribution approximates a blow-by-blow account.
-
- Changes much prior to version 2.0 are lost in the mists of time.
-
- *Plea:* Additions to this section are particularly welcome. If you
- or your friends (or enemies, to be evenhanded) have been unfairly
- omitted from this list, we would like to add your names!
-
- So that they may not regard their long labor as thankless, we
-particularly thank those who shepherded GDB through major releases: Fred
-Fish (releases 4.11, 4.10, 4.9), Stu Grossman and John Gilmore (releases
-4.8, 4.7, 4.6, 4.5, 4.4), John Gilmore (releases 4.3, 4.2, 4.1, 4.0, and
-3.9); Jim Kingdon (releases 3.5, 3.4, 3.3); and Randy Smith (releases
-3.2, 3.1, 3.0). As major maintainer of GDB for some period, each
-contributed significantly to the structure, stability, and capabilities
-of the entire debugger.
-
- Richard Stallman, assisted at various times by Peter TerMaat, Chris
-Hanson, and Richard Mlynarik, handled releases through 2.8.
-
- Michael Tiemann is the author of most of the GNU C++ support in GDB,
-with significant additional contributions from Per Bothner. James
-Clark wrote the GNU C++ demangler. Early work on C++ was by Peter
-TerMaat (who also did much general update work leading to release 3.0).
-
- GDB 4 uses the BFD subroutine library to examine multiple
-object-file formats; BFD was a joint project of David V.
-Henkel-Wallace, Rich Pixley, Steve Chamberlain, and John Gilmore.
-
- David Johnson wrote the original COFF support; Pace Willison did the
-original support for encapsulated COFF.
-
- Adam de Boor and Bradley Davis contributed the ISI Optimum V support.
-Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS
-support. Jean-Daniel Fekete contributed Sun 386i support. Chris
-Hanson improved the HP9000 support. Noboyuki Hikichi and Tomoyuki
-Hasei contributed Sony/News OS 3 support. David Johnson contributed
-Encore Umax support. Jyrki Kuoppala contributed Altos 3068 support.
-Keith Packard contributed NS32K support. Doug Rabson contributed Acorn
-Risc Machine support. Chris Smith contributed Convex support (and
-Fortran debugging). Jonathan Stone contributed Pyramid support.
-Michael Tiemann contributed SPARC support. Tim Tucker contributed
-support for the Gould NP1 and Gould Powernode. Pace Willison
-contributed Intel 386 support. Jay Vosburgh contributed Symmetry
-support.
-
- Rich Schaefer and Peter Schauer helped with support of SunOS shared
-libraries.
-
- Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about
-several machine instruction sets.
-
- Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped
-develop remote debugging. Intel Corporation and Wind River Systems
-contributed remote debugging modules for their products.
-
- Brian Fox is the author of the readline libraries providing
-command-line editing and command history.
-
- Andrew Beers of SUNY Buffalo wrote the language-switching code, the
-Modula-2 support, and contributed the Languages chapter of this manual.
-
- Fred Fish wrote most of the support for Unix System Vr4. He also
-enhanced the command-completion support to cover C++ overloaded symbols.
-
- Hitachi America, Ltd. sponsored the support for Hitachi
-microprocessors.

-New Features since GDB Version 3.5
-**********************************
-
-*Targets*
- Using the new command `target', you can select at runtime whether
- you are debugging local files, local processes, standalone systems
- over a serial port, realtime systems over a TCP/IP connection,
- etc. The command `load' can download programs into a remote
- system. Serial stubs are available for Motorola 680x0, Intel
- 80386, and Sparc remote systems; GDB also supports debugging
- realtime processes running under VxWorks, using SunRPC Remote
- Procedure Calls over TCP/IP to talk to a debugger stub on the
- target system. Internally, GDB now uses a function vector to
- mediate access to different targets; if you need to add your own
- support for a remote protocol, this makes it much easier.
-
-*Watchpoints*
- GDB now sports watchpoints as well as breakpoints. You can use a
- watchpoint to stop execution whenever the value of an expression
- changes, without having to predict a particular place in your
- program where this may happen.
-
-*Wide Output*
- Commands that issue wide output now insert newlines at places
- designed to make the output more readable.
-
-*Object Code Formats*
- GDB uses a new library called the Binary File Descriptor (BFD)
- Library to permit it to switch dynamically, without
- reconfiguration or recompilation, between different object-file
- formats. Formats currently supported are COFF, ELF, a.out, Intel
- 960 b.out, MIPS ECOFF, HPPA SOM (with stabs debugging), and
- S-records; files may be read as .o files, archive libraries, or
- core dumps. BFD is available as a subroutine library so that
- other programs may take advantage of it, and the other GNU binary
- utilities are being converted to use it.
-
-*Configuration and Ports*
- Compile-time configuration (to select a particular architecture and
- operating system) is much easier. The script `configure' now
- allows you to configure GDB as either a native debugger or a
- cross-debugger. *Note Installing GDB::, for details on how to
- configure.
-
-*Interaction*
- The user interface to the GDB control variables is simpler, and is
- consolidated in two commands, `set' and `show'. Output lines are
- now broken at readable places, rather than overflowing onto the
- next line. You can suppress output of machine-level addresses,
- displaying only source language information.
-
-*C++*
- GDB now supports C++ multiple inheritance (if used with a GCC
- version 2 compiler), and also has limited support for C++ exception
- handling, with the commands `catch' and `info catch': GDB can
- break when an exception is raised, before the stack is peeled back
- to the exception handler's context.
-
-*Modula-2*
- GDB now has preliminary support for the GNU Modula-2 compiler,
- currently under development at the State University of New York at
- Buffalo. Coordinated development of both GDB and the GNU Modula-2
- compiler will continue. Other Modula-2 compilers are currently
- not supported, and attempting to debug programs compiled with them
- will likely result in an error as the symbol table of the
- executable is read in.
-
-*Command Rationalization*
- Many GDB commands have been renamed to make them easier to remember
- and use. In particular, the subcommands of `info' and
- `show'/`set' are grouped to make the former refer to the state of
- your program, and the latter refer to the state of GDB itself.
- *Note Renamed Commands::, for details on what commands were
- renamed.
-
-*Shared Libraries*
- GDB 4 can debug programs and core files that use SunOS, SVR4, or
- IBM RS/6000 shared libraries.
-
-*Reference Card*
- GDB 4 has a reference card. *Note Formatting the Documentation:
- Formatting Documentation, for instructions about how to print it.

-A Sample GDB Session
-********************
-
- You can use this manual at your leisure to read all about GDB.
-However, a handful of commands are enough to get started using the
-debugger. This chapter illustrates those commands.
-
- One of the preliminary versions of GNU `m4' (a generic macro
-processor) exhibits the following bug: sometimes, when we change its
-quote strings from the default, the commands used to capture one macro
-definition within another stop working. In the following short `m4'
-session, we define a macro `foo' which expands to `0000'; we then use
-the `m4' built-in `defn' to define `bar' as the same thing. However,
-when we change the open quote string to `<QUOTE>' and the close quote
-string to `<UNQUOTE>', the same procedure fails to define a new synonym
-`baz':
-
- $ cd gnu/m4
- $ ./m4
- define(foo,0000)
-
- foo
- 0000
- define(bar,defn(`foo'))
-
- bar
- 0000
- changequote(<QUOTE>,<UNQUOTE>)
-
- define(baz,defn(<QUOTE>foo<UNQUOTE>))
- baz
- C-d
- m4: End of input: 0: fatal error: EOF in string
-
-Let us use GDB to try to see what is going on.
-
- $ gdb m4
- GDB is free software and you are welcome to distribute copies
- of it under certain conditions; type "show copying" to see
- the conditions.
- There is absolutely no warranty for GDB; type "show warranty"
- for details.
- GDB 4.11, Copyright 1993 Free Software Foundation, Inc...
- (gdb)
-
-GDB reads only enough symbol data to know where to find the rest when
-needed; as a result, the first prompt comes up very quickly. We now
-tell GDB to use a narrower display width than usual, so that examples
-will fit in this manual.
-
- (gdb) set width 70
-
-We need to see how the `m4' built-in `changequote' works. Having
-looked at the source, we know the relevant subroutine is
-`m4_changequote', so we set a breakpoint there with the GDB `break'
-command.
-
- (gdb) break m4_changequote
- Breakpoint 1 at 0x62f4: file builtin.c, line 879.
-
-Using the `run' command, we start `m4' running under GDB control; as
-long as control does not reach the `m4_changequote' subroutine, the
-program runs as usual:
-
- (gdb) run
- Starting program: /work/Editorial/gdb/gnu/m4/m4
- define(foo,0000)
-
- foo
- 0000
-
-To trigger the breakpoint, we call `changequote'. GDB suspends
-execution of `m4', displaying information about the context where it
-stops.
-
- changequote(<QUOTE>,<UNQUOTE>)
-
- Breakpoint 1, m4_changequote (argc=3, argv=0x33c70)
- at builtin.c:879
- 879 if (bad_argc(TOKEN_DATA_TEXT(argv[0]),argc,1,3))
-
-Now we use the command `n' (`next') to advance execution to the next
-line of the current function.
-
- (gdb) n
- 882 set_quotes((argc >= 2) ? TOKEN_DATA_TEXT(argv[1])\
- : nil,
-
-`set_quotes' looks like a promising subroutine. We can go into it by
-using the command `s' (`step') instead of `next'. `step' goes to the
-next line to be executed in *any* subroutine, so it steps into
-`set_quotes'.
-
- (gdb) s
- set_quotes (lq=0x34c78 "<QUOTE>", rq=0x34c88 "<UNQUOTE>")
- at input.c:530
- 530 if (lquote != def_lquote)
-
-The display that shows the subroutine where `m4' is now suspended (and
-its arguments) is called a stack frame display. It shows a summary of
-the stack. We can use the `backtrace' command (which can also be
-spelled `bt'), to see where we are in the stack as a whole: the
-`backtrace' command displays a stack frame for each active subroutine.
-
- (gdb) bt
- #0 set_quotes (lq=0x34c78 "<QUOTE>", rq=0x34c88 "<UNQUOTE>")
- at input.c:530
- #1 0x6344 in m4_changequote (argc=3, argv=0x33c70)
- at builtin.c:882
- #2 0x8174 in expand_macro (sym=0x33320) at macro.c:242
- #3 0x7a88 in expand_token (obs=0x0, t=209696, td=0xf7fffa30)
- at macro.c:71
- #4 0x79dc in expand_input () at macro.c:40
- #5 0x2930 in main (argc=0, argv=0xf7fffb20) at m4.c:195
-
-We will step through a few more lines to see what happens. The first
-two times, we can use `s'; the next two times we use `n' to avoid
-falling into the `xstrdup' subroutine.
-
- (gdb) s
- 0x3b5c 532 if (rquote != def_rquote)
- (gdb) s
- 0x3b80 535 lquote = (lq == nil || *lq == '\0') ? \
- def_lquote : xstrdup(lq);
- (gdb) n
- 536 rquote = (rq == nil || *rq == '\0') ? def_rquote\
- : xstrdup(rq);
- (gdb) n
- 538 len_lquote = strlen(rquote);
-
-The last line displayed looks a little odd; we can examine the variables
-`lquote' and `rquote' to see if they are in fact the new left and right
-quotes we specified. We use the command `p' (`print') to see their
-values.
-
- (gdb) p lquote
- $1 = 0x35d40 "<QUOTE>"
- (gdb) p rquote
- $2 = 0x35d50 "<UNQUOTE>"
-
-`lquote' and `rquote' are indeed the new left and right quotes. To
-look at some context, we can display ten lines of source surrounding
-the current line with the `l' (`list') command.
-
- (gdb) l
- 533 xfree(rquote);
- 534
- 535 lquote = (lq == nil || *lq == '\0') ? def_lquote\
- : xstrdup (lq);
- 536 rquote = (rq == nil || *rq == '\0') ? def_rquote\
- : xstrdup (rq);
- 537
- 538 len_lquote = strlen(rquote);
- 539 len_rquote = strlen(lquote);
- 540 }
- 541
- 542 void
-
-Let us step past the two lines that set `len_lquote' and `len_rquote',
-and then examine the values of those variables.
-
- (gdb) n
- 539 len_rquote = strlen(lquote);
- (gdb) n
- 540 }
- (gdb) p len_lquote
- $3 = 9
- (gdb) p len_rquote
- $4 = 7
-
-That certainly looks wrong, assuming `len_lquote' and `len_rquote' are
-meant to be the lengths of `lquote' and `rquote' respectively. We can
-set them to better values using the `p' command, since it can print the
-value of any expression--and that expression can include subroutine
-calls and assignments.
-
- (gdb) p len_lquote=strlen(lquote)
- $5 = 7
- (gdb) p len_rquote=strlen(rquote)
- $6 = 9
-
-Is that enough to fix the problem of using the new quotes with the `m4'
-built-in `defn'? We can allow `m4' to continue executing with the `c'
-(`continue') command, and then try the example that caused trouble
-initially:
-
- (gdb) c
- Continuing.
-
- define(baz,defn(<QUOTE>foo<UNQUOTE>))
-
- baz
- 0000
-
-Success! The new quotes now work just as well as the default ones. The
-problem seems to have been just the two typos defining the wrong
-lengths. We allow `m4' exit by giving it an EOF as input:
-
- C-d
- Program exited normally.
-
-The message `Program exited normally.' is from GDB; it indicates `m4'
-has finished executing. We can end our GDB session with the GDB `quit'
-command.
-
- (gdb) quit

-
- This chapter discusses how to start GDB, and how to get out of it.
-(The essentials: type `gdb' to start GDB, and type `quit' or `C-d' to
-exit.)

-
-Invoking GDB
-============
-
- Invoke GDB by running the program `gdb'. Once started, GDB reads
-commands from the terminal until you tell it to exit.
-
- You can also run `gdb' with a variety of arguments and options, to
-specify more of your debugging environment at the outset.
-
- The command-line options described here are designed to cover a
-variety of situations; in some environments, some of these options may
-effectively be unavailable.
-
- The most usual way to start GDB is with one argument, specifying an
-executable program:
-
- gdb PROGRAM
-
-You can also start with both an executable program and a core file
-specified:
-
- gdb PROGRAM CORE
-
- You can, instead, specify a process ID as a second argument, if you
-want to debug a running process:
-
- gdb PROGRAM 1234
-
-would attach GDB to process `1234' (unless you also have a file named
-`1234'; GDB does check for a core file first).
-
- Taking advantage of the second command-line argument requires a
-fairly complete operating system; when you use GDB as a remote debugger
-attached to a bare board, there may not be any notion of "process", and
-there is often no way to get a core dump.
-
-You can further control how GDB starts up by using command-line
-options. GDB itself can remind you of the options available.
-
-Type
-
- gdb -help
-
-to display all available options and briefly describe their use (`gdb
--h' is a shorter equivalent).
-
- All options and command line arguments you give are processed in
-sequential order. The order makes a difference when the `-x' option is
-used.

-
-Choosing files
---------------
-
- When GDB starts, it reads any arguments other than options as
-specifying an executable file and core file (or process ID). This is
-the same as if the arguments were specified by the `-se' and `-c'
-options respectively. (GDB reads the first argument that does not have
-an associated option flag as equivalent to the `-se' option followed by
-that argument; and the second argument that does not have an associated
-option flag, if any, as equivalent to the `-c' option followed by that
-argument.)
-
- Many options have both long and short forms; both are shown in the
-following list. GDB also recognizes the long forms if you truncate
-them, so long as enough of the option is present to be unambiguous.
-(If you prefer, you can flag option arguments with `--' rather than
-`-', though we illustrate the more usual convention.)
-
-`-symbols FILE'
-`-s FILE'
- Read symbol table from file FILE.
-
-`-exec FILE'
-`-e FILE'
- Use file FILE as the executable file to execute when appropriate,
- and for examining pure data in conjunction with a core dump.
-
-`-se FILE'
- Read symbol table from file FILE and use it as the executable file.
-
-`-core FILE'
-`-c FILE'
- Use file FILE as a core dump to examine.
-
-`-c NUMBER'
- Connect to process ID NUMBER, as with the `attach' command (unless
- there is a file in core-dump format named NUMBER, in which case
- `-c' specifies that file as a core dump to read).
-
-`-command FILE'
-`-x FILE'
- Execute GDB commands from file FILE. *Note Command files: Command
- Files.
-
-`-directory DIRECTORY'
-`-d DIRECTORY'
- Add DIRECTORY to the path to search for source files.
-
-`-m'
-`-mapped'
- *Warning: this option depends on operating system facilities that
- are not supported on all systems.*
- If memory-mapped files are available on your system through the
- `mmap' system call, you can use this option to have GDB write the
- symbols from your program into a reusable file in the current
- directory. If the program you are debugging is called
- `/tmp/fred', the mapped symbol file will be `./fred.syms'. Future
- GDB debugging sessions will notice the presence of this file, and
- will quickly map in symbol information from it, rather than reading
- the symbol table from the executable program.
-
- The `.syms' file is specific to the host machine where GDB is run.
- It holds an exact image of the internal GDB symbol table. It
- cannot be shared across multiple host platforms.
-
-`-r'
-`-readnow'
- Read each symbol file's entire symbol table immediately, rather
- than the default, which is to read it incrementally as it is
- needed. This makes startup slower, but makes future operations
- faster.
-
- The `-mapped' and `-readnow' options are typically combined in order
-to build a `.syms' file that contains complete symbol information.
-(*Note Commands to specify files: Files, for information on `.syms'
-files.) A simple GDB invocation to do nothing but build a `.syms' file
-for future use is:
-
- gdb -batch -nx -mapped -readnow programname
-
-
-File: gdb.info, Node: Mode Options, Prev: File Options, Up: Invoking GDB
-
-Choosing modes
---------------
-
- You can run GDB in various alternative modes--for example, in batch
-mode or quiet mode.
-
-`-nx'
-`-n'
- Do not execute commands from any initialization files (normally
- called `.gdbinit'). Normally, the commands in these files are
- executed after all the command options and arguments have been
- processed. *Note Command files: Command Files.
-
-`-quiet'
-`-q'
- "Quiet". Do not print the introductory and copyright messages.
- These messages are also suppressed in batch mode.
-
-`-batch'
- Run in batch mode. Exit with status `0' after processing all the
- command files specified with `-x' (and all commands from
- initialization files, if not inhibited with `-n'). Exit with
- nonzero status if an error occurs in executing the GDB commands in
- the command files.
-
- Batch mode may be useful for running GDB as a filter, for example
- to download and run a program on another computer; in order to
- make this more useful, the message
-
- Program exited normally.
-
- (which is ordinarily issued whenever a program running under GDB
- control terminates) is not issued when running in batch mode.
-
-`-cd DIRECTORY'
- Run GDB using DIRECTORY as its working directory, instead of the
- current directory.
-
-`-fullname'
-`-f'
- Emacs sets this option when it runs GDB as a subprocess. It tells
- GDB to output the full file name and line number in a standard,
- recognizable fashion each time a stack frame is displayed (which
- includes each time your program stops). This recognizable format
- looks like two `\032' characters, followed by the file name, line
- number and character position separated by colons, and a newline.
- The Emacs-to-GDB interface program uses the two `\032' characters
- as a signal to display the source code for the frame.
-
-`-b BPS'
- Set the line speed (baud rate or bits per second) of any serial
- interface used by GDB for remote debugging.
-
-`-tty DEVICE'
- Run using DEVICE for your program's standard input and output.
-
-
-File: gdb.info, Node: Quitting GDB, Next: Shell Commands, Prev: Invoking GDB, Up: Invocation
-
-Quitting GDB
-============
-
-`quit'
- To exit GDB, use the `quit' command (abbreviated `q'), or type an
- end-of-file character (usually `C-d').
-
- An interrupt (often `C-c') will not exit from GDB, but rather will
-terminate the action of any GDB command that is in progress and return
-to GDB command level. It is safe to type the interrupt character at
-any time because GDB does not allow it to take effect until a time when
-it is safe.
-
- If you have been using GDB to control an attached process or device,
-you can release it with the `detach' command (*note Debugging an
-already-running process: Attach.).
-
-
-File: gdb.info, Node: Shell Commands, Prev: Quitting GDB, Up: Invocation
-
-Shell commands
-==============
-
- If you need to execute occasional shell commands during your
-debugging session, there is no need to leave or suspend GDB; you can
-just use the `shell' command.
-
-`shell COMMAND STRING'
- Invoke a the standard shell to execute COMMAND STRING. If it
- exists, the environment variable `SHELL' determines which shell to
- run. Otherwise GDB uses `/bin/sh'.
-
- The utility `make' is often needed in development environments. You
-do not have to use the `shell' command for this purpose in GDB:
-
-`make MAKE-ARGS'
- Execute the `make' program with the specified arguments. This is
- equivalent to `shell make MAKE-ARGS'.

-
-GDB Commands
-************
-
- You can abbreviate a GDB command to the first few letters of the
-command name, if that abbreviation is unambiguous; and you can repeat
-certain GDB commands by typing just RET. You can also use the TAB key
-to get GDB to fill out the rest of a word in a command (or to show you
-the alternatives available, if there is more than one possibility).

-
-
-File: gdb.info, Node: Command Syntax, Next: Completion, Up: Commands
-
-Command syntax
-==============
-
- A GDB command is a single line of input. There is no limit on how
-long it can be. It starts with a command name, which is followed by
-arguments whose meaning depends on the command name. For example, the
-command `step' accepts an argument which is the number of times to
-step, as in `step 5'. You can also use the `step' command with no
-arguments. Some command names do not allow any arguments.
-
- GDB command names may always be truncated if that abbreviation is
-unambiguous. Other possible command abbreviations are listed in the
-documentation for individual commands. In some cases, even ambiguous
-abbreviations are allowed; for example, `s' is specially defined as
-equivalent to `step' even though there are other commands whose names
-start with `s'. You can test abbreviations by using them as arguments
-to the `help' command.
-
- A blank line as input to GDB (typing just RET) means to repeat the
-previous command. Certain commands (for example, `run') will not repeat
-this way; these are commands for which unintentional repetition might
-cause trouble and which you are unlikely to want to repeat.
-
- The `list' and `x' commands, when you repeat them with RET,
-construct new arguments rather than repeating exactly as typed. This
-permits easy scanning of source or memory.
-
- GDB can also use RET in another way: to partition lengthy output, in
-a way similar to the common utility `more' (*note Screen size: Screen
-Size.). Since it is easy to press one RET too many in this situation,
-GDB disables command repetition after any command that generates this
-sort of display.
-
- Any text from a `#' to the end of the line is a comment; it does
-nothing. This is useful mainly in command files (*note Command files:
-Command Files.).
-

-
-Command completion
-==================
-
- GDB can fill in the rest of a word in a command for you, if there is
-only one possibility; it can also show you what the valid possibilities
-are for the next word in a command, at any time. This works for GDB
-commands, GDB subcommands, and the names of symbols in your program.
-
- Press the TAB key whenever you want GDB to fill out the rest of a
-word. If there is only one possibility, GDB will fill in the word, and
-wait for you to finish the command (or press RET to enter it). For
-example, if you type
-
- (gdb) info bre TAB
-
-GDB fills in the rest of the word `breakpoints', since that is the only
-`info' subcommand beginning with `bre':
-
- (gdb) info breakpoints
-
-You can either press RET at this point, to run the `info breakpoints'
-command, or backspace and enter something else, if `breakpoints' does
-not look like the command you expected. (If you were sure you wanted
-`info breakpoints' in the first place, you might as well just type RET
-immediately after `info bre', to exploit command abbreviations rather
-than command completion).
-
- If there is more than one possibility for the next word when you
-press TAB, GDB will sound a bell. You can either supply more
-characters and try again, or just press TAB a second time, and GDB will
-display all the possible completions for that word. For example, you
-might want to set a breakpoint on a subroutine whose name begins with
-`make_', but when you type `b make_TAB' GDB just sounds the bell.
-Typing TAB again will display all the function names in your program
-that begin with those characters, for example:
-
- (gdb) b make_ TAB
-GDB sounds bell; press TAB again, to see:
- make_a_section_from_file make_environ
- make_abs_section make_function_type
- make_blockvector make_pointer_type
- make_cleanup make_reference_type
- make_command make_symbol_completion_list
- (gdb) b make_
-
-After displaying the available possibilities, GDB copies your partial
-input (`b make_' in the example) so you can finish the command.
-
- If you just want to see the list of alternatives in the first place,
-you can press `M-?' rather than pressing TAB twice. `M-?' means `META
-?'. You can type this either by holding down a key designated as the
-META shift on your keyboard (if there is one) while typing `?', or as
-ESC followed by `?'.
-
- Sometimes the string you need, while logically a "word", may contain
-parentheses or other characters that GDB normally excludes from its
-notion of a word. To permit word completion to work in this situation,
-you may enclose words in `'' (single quote marks) in GDB commands.
-
- The most likely situation where you might need this is in typing the
-name of a C++ function. This is because C++ allows function overloading
-(multiple definitions of the same function, distinguished by argument
-type). For example, when you want to set a breakpoint you may need to
-distinguish whether you mean the version of `name' that takes an `int'
-parameter, `name(int)', or the version that takes a `float' parameter,
-`name(float)'. To use the word-completion facilities in this
-situation, type a single quote `'' at the beginning of the function
-name. This alerts GDB that it may need to consider more information
-than usual when you press TAB or `M-?' to request word completion:
-
- (gdb) b 'bubble( M-?
- bubble(double,double) bubble(int,int)
- (gdb) b 'bubble(
-
- In some cases, GDB can tell that completing a name will require
-quotes. When this happens, GDB will insert the quote for you (while
-completing as much as it can) if you do not type the quote in the first
-place:
-
- (gdb) b bub TAB
-GDB alters your input line to the following, and rings a bell:
- (gdb) b 'bubble(
-
-In general, GDB can tell that a quote is needed (and inserts it) if you
-have not yet started typing the argument list when you ask for
-completion on an overloaded symbol.
-
-
-File: gdb.info, Node: Help, Prev: Completion, Up: Commands
-
-Getting help
-============
-
- You can always ask GDB itself for information on its commands, using
-the command `help'.
-
-`help'
-`h'
- You can use `help' (abbreviated `h') with no arguments to display
- a short list of named classes of commands:
-
- (gdb) help
- List of classes of commands:
-
- running -- Running the program
- stack -- Examining the stack
- data -- Examining data
- breakpoints -- Making program stop at certain points
- files -- Specifying and examining files
- status -- Status inquiries
- support -- Support facilities
- user-defined -- User-defined commands
- aliases -- Aliases of other commands
- obscure -- Obscure features
-
- Type "help" followed by a class name for a list of
- commands in that class.
- Type "help" followed by command name for full
- documentation.
- Command name abbreviations are allowed if unambiguous.
- (gdb)
-
-`help CLASS'
- Using one of the general help classes as an argument, you can get a
- list of the individual commands in that class. For example, here
- is the help display for the class `status':
-
- (gdb) help status
- Status inquiries.
-
- List of commands:
-
- show -- Generic command for showing things set
- with "set"
- info -- Generic command for printing status
-
- Type "help" followed by command name for full
- documentation.
- Command name abbreviations are allowed if unambiguous.
- (gdb)
-
-`help COMMAND'
- With a command name as `help' argument, GDB will display a short
- paragraph on how to use that command.
-
- In addition to `help', you can use the GDB commands `info' and
-`show' to inquire about the state of your program, or the state of GDB
-itself. Each command supports many topics of inquiry; this manual
-introduces each of them in the appropriate context. The listings under
-`info' and under `show' in the Index point to all the sub-commands.
-*Note Index::.
-
-`info'
- This command (abbreviated `i') is for describing the state of your
- program. For example, you can list the arguments given to your
- program with `info args', list the registers currently in use with
- `info registers', or list the breakpoints you have set with `info
- breakpoints'. You can get a complete list of the `info'
- sub-commands with `help info'.
-
-`show'
- In contrast, `show' is for describing the state of GDB itself.
- You can change most of the things you can `show', by using the
- related command `set'; for example, you can control what number
- system is used for displays with `set radix', or simply inquire
- which is currently in use with `show radix'.
-
- To display all the settable parameters and their current values,
- you can use `show' with no arguments; you may also use `info set'.
- Both commands produce the same display.
-
- Here are three miscellaneous `show' subcommands, all of which are
-exceptional in lacking corresponding `set' commands:
-
-`show version'
- Show what version of GDB is running. You should include this
- information in GDB bug-reports. If multiple versions of GDB are in
- use at your site, you may occasionally want to determine which
- version of GDB you are running; as GDB evolves, new commands are
- introduced, and old ones may wither away. The version number is
- also announced when you start GDB.
-
-`show copying'
- Display information about permission for copying GDB.
-
-`show warranty'
- Display the GNU "NO WARRANTY" statement.

-Running Programs Under GDB
-**************************
-
- When you run a program under GDB, you must first generate debugging
-information when you compile it. You may start it with its arguments,
-if any, in an environment of your choice. You may redirect your
-program's input and output, debug an already running process, or kill a
-child process.

-
-Compiling for debugging
-=======================
-
- In order to debug a program effectively, you need to generate
-debugging information when you compile it. This debugging information
-is stored in the object file; it describes the data type of each
-variable or function and the correspondence between source line numbers
-and addresses in the executable code.
-
- To request debugging information, specify the `-g' option when you
-run the compiler.
-
- Many C compilers are unable to handle the `-g' and `-O' options
-together. Using those compilers, you cannot generate optimized
-executables containing debugging information.
-
- GCC, the GNU C compiler, supports `-g' with or without `-O', making
-it possible to debug optimized code. We recommend that you *always*
-use `-g' whenever you compile a program. You may think your program is
-correct, but there is no sense in pushing your luck.
-
- When you debug a program compiled with `-g -O', remember that the
-optimizer is rearranging your code; the debugger will show you what is
-really there. Do not be too surprised when the execution path does not
-exactly match your source file! An extreme example: if you define a
-variable, but never use it, GDB will never see that variable--because
-the compiler optimizes it out of existence.
-
- Some things do not work as well with `-g -O' as with just `-g',
-particularly on machines with instruction scheduling. If in doubt,
-recompile with `-g' alone, and if this fixes the problem, please report
-it as a bug (including a test case!).
-
- Older versions of the GNU C compiler permitted a variant option
-`-gg' for debugging information. GDB no longer supports this format;
-if your GNU C compiler has this option, do not use it.
-
-
-File: gdb.info, Node: Starting, Next: Arguments, Prev: Compilation, Up: Running
-
-Starting your program
-=====================
-
-`run'
-`r'
- Use the `run' command to start your program under GDB. You must
- first specify the program name (except on VxWorks) with an
- argument to GDB (*note Getting In and Out of GDB: Invocation.), or
- by using the `file' or `exec-file' command (*note Commands to
- specify files: Files.).
-
- If you are running your program in an execution environment that
-supports processes, `run' creates an inferior process and makes that
-process run your program. (In environments without processes, `run'
-jumps to the start of your program.)
-
- The execution of a program is affected by certain information it
-receives from its superior. GDB provides ways to specify this
-information, which you must do *before* starting your program. (You
-can change it after starting your program, but such changes will only
-affect your program the next time you start it.) This information may
-be divided into four categories:
-
-The *arguments.*
- Specify the arguments to give your program as the arguments of the
- `run' command. If a shell is available on your target, the shell
- is used to pass the arguments, so that you may use normal
- conventions (such as wildcard expansion or variable substitution)
- in describing the arguments. In Unix systems, you can control
- which shell is used with the `SHELL' environment variable. *Note
- Your program's arguments: Arguments.
-
-The *environment.*
- Your program normally inherits its environment from GDB, but you
- can use the GDB commands `set environment' and `unset environment'
- to change parts of the environment that will be given to your
- program. *Note Your program's environment: Environment.
-
-The *working directory.*
- Your program inherits its working directory from GDB. You can set
- the GDB working directory with the `cd' command in GDB. *Note
- Your program's working directory: Working Directory.
-
-The *standard input and output.*
- Your program normally uses the same device for standard input and
- standard output as GDB is using. You can redirect input and output
- in the `run' command line, or you can use the `tty' command to set
- a different device for your program. *Note Your program's input
- and output: Input/Output.
-
- *Warning:* While input and output redirection work, you cannot use
- pipes to pass the output of the program you are debugging to
- another program; if you attempt this, GDB is likely to wind up
- debugging the wrong program.
-
- When you issue the `run' command, your program begins to execute
-immediately. *Note Stopping and continuing: Stopping, for discussion
-of how to arrange for your program to stop. Once your program has
-stopped, you may call functions in your program, using the `print' or
-`call' commands. *Note Examining Data: Data.
-
- If the modification time of your symbol file has changed since the
-last time GDB read its symbols, GDB will discard its symbol table and
-re-read it. When it does this, GDB tries to retain your current
-breakpoints.
-
-
-File: gdb.info, Node: Arguments, Next: Environment, Prev: Starting, Up: Running
-
-Your program's arguments
-========================
-
- The arguments to your program can be specified by the arguments of
-the `run' command. They are passed to a shell, which expands wildcard
-characters and performs redirection of I/O, and thence to your program.
-Your `SHELL' environment variable (if it exists) specifies what shell
-GDB if you do not define `SHELL', GDB uses `/bin/sh'.
-
- `run' with no arguments uses the same arguments used by the previous
-`run', or those set by the `set args' command.
-
-`set args'
- Specify the arguments to be used the next time your program is
- run. If `set args' has no arguments, `run' will execute your
- program with no arguments. Once you have run your program with
- arguments, using `set args' before the next `run' is the only way
- to run it again without arguments.
-
-`show args'
- Show the arguments to give your program when it is started.
-
-
-File: gdb.info, Node: Environment, Next: Working Directory, Prev: Arguments, Up: Running
-
-Your program's environment
-==========================
-
- The "environment" consists of a set of environment variables and
-their values. Environment variables conventionally record such things
-as your user name, your home directory, your terminal type, and your
-search path for programs to run. Usually you set up environment
-variables with the shell and they are inherited by all the other
-programs you run. When debugging, it can be useful to try running your
-program with a modified environment without having to start GDB over
-again.
-
-`path DIRECTORY'
- Add DIRECTORY to the front of the `PATH' environment variable (the
- search path for executables), for both GDB and your program. You
- may specify several directory names, separated by `:' or
- whitespace. If DIRECTORY is already in the path, it is moved to
- the front, so it will be searched sooner.
-
- You can use the string `$cwd' to refer to whatever is the current
- working directory at the time GDB searches the path. If you use
- `.' instead, it refers to the directory where you executed the
- `path' command. GDB replaces `.' in the DIRECTORY argument (with
- the current path) before adding DIRECTORY to the search path.
-
-`show paths'
- Display the list of search paths for executables (the `PATH'
- environment variable).
-
-`show environment [VARNAME]'
- Print the value of environment variable VARNAME to be given to
- your program when it starts. If you do not supply VARNAME, print
- the names and values of all environment variables to be given to
- your program. You can abbreviate `environment' as `env'.
-
-`set environment VARNAME [=] VALUE'
- Set environment variable VARNAME to VALUE. The value changes for
- your program only, not for GDB itself. VALUE may be any string;
- the values of environment variables are just strings, and any
- interpretation is supplied by your program itself. The VALUE
- parameter is optional; if it is eliminated, the variable is set to
- a null value.
-
- For example, this command:
-
- set env USER = foo
-
- tells a Unix program, when subsequently run, that its user is named
- `foo'. (The spaces around `=' are used for clarity here; they are
- not actually required.)
-
-`unset environment VARNAME'
- Remove variable VARNAME from the environment to be passed to your
- program. This is different from `set env VARNAME ='; `unset
- environment' removes the variable from the environment, rather
- than assigning it an empty value.
-
- *Warning:* GDB runs your program using the shell indicated by your
-`SHELL' environment variable if it exists (or `/bin/sh' if not). If
-your `SHELL' variable names a shell that runs an initialization
-file--such as `.cshrc' for C-shell, or `.bashrc' for BASH--any
-variables you set in that file will affect your program. You may wish
-to move setting of environment variables to files that are only run
-when you sign on, such as `.login' or `.profile'.

-
-Your program's working directory
-================================
-
- Each time you start your program with `run', it inherits its working
-directory from the current working directory of GDB. The GDB working
-directory is initially whatever it inherited from its parent process
-(typically the shell), but you can specify a new working directory in
-GDB with the `cd' command.
-
- The GDB working directory also serves as a default for the commands
-that specify files for GDB to operate on. *Note Commands to specify
-files: Files.
-
-`cd DIRECTORY'
- Set the GDB working directory to DIRECTORY.
-
-`pwd'
- Print the GDB working directory.
-
-
-File: gdb.info, Node: Input/Output, Next: Attach, Prev: Working Directory, Up: Running
-
-Your program's input and output
-===============================
-
- By default, the program you run under GDB does input and output to
-the same terminal that GDB uses. GDB switches the terminal to its own
-terminal modes to interact with you, but it records the terminal modes
-your program was using and switches back to them when you continue
-running your program.
-
-`info terminal'
- Displays information recorded by GDB about the terminal modes your
- program is using.
-
- You can redirect your program's input and/or output using shell
-redirection with the `run' command. For example,
-
- run > outfile
-
-starts your program, diverting its output to the file `outfile'.
-
- Another way to specify where your program should do input and output
-is with the `tty' command. This command accepts a file name as
-argument, and causes this file to be the default for future `run'
-commands. It also resets the controlling terminal for the child
-process, for future `run' commands. For example,
-
- tty /dev/ttyb
-
-directs that processes started with subsequent `run' commands default
-to do input and output on the terminal `/dev/ttyb' and have that as
-their controlling terminal.
-
- An explicit redirection in `run' overrides the `tty' command's
-effect on the input/output device, but not its effect on the controlling
-terminal.
-
- When you use the `tty' command or redirect input in the `run'
-command, only the input *for your program* is affected. The input for
-GDB still comes from your terminal.

-
-Debugging an already-running process
-====================================
-
-`attach PROCESS-ID'
- This command attaches to a running process--one that was started
- outside GDB. (`info files' will show your active targets.) The
- command takes as argument a process ID. The usual way to find out
- the process-id of a Unix process is with the `ps' utility, or with
- the `jobs -l' shell command.
-
- `attach' will not repeat if you press RET a second time after
- executing the command.
-
- To use `attach', your program must be running in an environment
-which supports processes; for example, `attach' does not work for
-programs on bare-board targets that lack an operating system. You must
-also have permission to send the process a signal.
-
- When using `attach', you should first use the `file' command to
-specify the program running in the process and load its symbol table.
-*Note Commands to Specify Files: Files.
-
- The first thing GDB does after arranging to debug the specified
-process is to stop it. You can examine and modify an attached process
-with all the GDB commands that are ordinarily available when you start
-processes with `run'. You can insert breakpoints; you can step and
-continue; you can modify storage. If you would rather the process
-continue running, you may use the `continue' command after attaching
-GDB to the process.
-
-`detach'
- When you have finished debugging the attached process, you can use
- the `detach' command to release it from GDB control. Detaching
- the process continues its execution. After the `detach' command,
- that process and GDB become completely independent once more, and
- you are ready to `attach' another process or start one with `run'.
- `detach' will not repeat if you press RET again after executing
- the command.
-
- If you exit GDB or use the `run' command while you have an attached
-process, you kill that process. By default, you will be asked for
-confirmation if you try to do either of these things; you can control
-whether or not you need to confirm by using the `set confirm' command
-(*note Optional warnings and messages: Messages/Warnings.).
-
-
-File: gdb.info, Node: Kill Process, Next: Process Information, Prev: Attach, Up: Running
-
-Killing the child process
-=========================
-
-`kill'
- Kill the child process in which your program is running under GDB.
-
- This command is useful if you wish to debug a core dump instead of a
-running process. GDB ignores any core dump file while your program is
-running.
-
- On some operating systems, a program cannot be executed outside GDB
-while you have breakpoints set on it inside GDB. You can use the
-`kill' command in this situation to permit running your program outside
-the debugger.
-
- The `kill' command is also useful if you wish to recompile and
-relink your program, since on many systems it is impossible to modify an
-executable file while it is running in a process. In this case, when
-you next type `run', GDB will notice that the file has changed, and
-will re-read the symbol table (while trying to preserve your current
-breakpoint settings).
-
-
-File: gdb.info, Node: Process Information, Prev: Kill Process, Up: Running
-
-Additional process information
-==============================
-
- Some operating systems provide a facility called `/proc' that can be
-used to examine the image of a running process using file-system
-subroutines. If GDB is configured for an operating system with this
-facility, the command `info proc' is available to report on several
-kinds of information about the process running your program.
-
-`info proc'
- Summarize available information about the process.
-
-`info proc mappings'
- Report on the address ranges accessible in the program, with
- information on whether your program may read, write, or execute
- each range.
-
-`info proc times'
- Starting time, user CPU time, and system CPU time for your program
- and its children.
-
-`info proc id'
- Report on the process IDs related to your program: its own process
- ID, the ID of its parent, the process group ID, and the session ID.
-
-`info proc status'
- General information on the state of the process. If the process is
- stopped, this report includes the reason for stopping, and any
- signal received.
-
-`info proc all'
- Show all the above information about the process.

-Stopping and Continuing
-***********************
-
- The principal purposes of using a debugger are so that you can stop
-your program before it terminates; or so that, if your program runs into
-trouble, you can investigate and find out why.
-
- Inside GDB, your program may stop for any of several reasons, such as
-a signal, a breakpoint, or reaching a new line after a GDB command such
-as `step'. You may then examine and change variables, set new
-breakpoints or remove old ones, and then continue execution. Usually,
-the messages shown by GDB provide ample explanation of the status of
-your program--but you can also explicitly request this information at
-any time.
-
-`info program'
- Display information about the status of your program: whether it is
- running or not, what process it is, and why it stopped.

-
-Breakpoints, watchpoints, and exceptions
-========================================
-
- A "breakpoint" makes your program stop whenever a certain point in
-the program is reached. For each breakpoint, you can add various
-conditions to control in finer detail whether your program will stop.
-You can set breakpoints with the `break' command and its variants
-(*note Setting breakpoints: Set Breaks.), to specify the place where
-your program should stop by line number, function name or exact address
-in the program. In languages with exception handling (such as GNU
-C++), you can also set breakpoints where an exception is raised (*note
-Breakpoints and exceptions: Exception Handling.).
-
- A "watchpoint" is a special breakpoint that stops your program when
-the value of an expression changes. You must use a different command
-to set watchpoints (*note Setting watchpoints: Set Watchpoints.), but
-aside from that, you can manage a watchpoint like any other breakpoint:
-you enable, disable, and delete both breakpoints and watchpoints using
-the same commands.
-
- You can arrange to have values from your program displayed
-automatically whenever GDB stops at a breakpoint. *Note Automatic
-display: Auto Display.
-
- GDB assigns a number to each breakpoint or watchpoint when you
-create it; these numbers are successive integers starting with one. In
-many of the commands for controlling various features of breakpoints you
-use the breakpoint number to say which breakpoint you want to change.
-Each breakpoint may be "enabled" or "disabled"; if disabled, it has no
-effect on your program until you enable it again.

-
-Setting breakpoints
--------------------
-
- Breakpoints are set with the `break' command (abbreviated `b'). The
-debugger convenience variable `$bpnum' records the number of the
-beakpoint you've set most recently; see *Note Convenience variables:
-Convenience Vars, for a discussion of what you can do with convenience
-variables.
-
- You have several ways to say where the breakpoint should go.
-
-`break FUNCTION'
- Set a breakpoint at entry to function FUNCTION. When using source
- languages that permit overloading of symbols, such as C++,
- FUNCTION may refer to more than one possible place to break.
- *Note Breakpoint menus: Breakpoint Menus, for a discussion of that
- situation.
-
-`break +OFFSET'
-`break -OFFSET'
- Set a breakpoint some number of lines forward or back from the
- position at which execution stopped in the currently selected
- frame.
-
-`break LINENUM'
- Set a breakpoint at line LINENUM in the current source file. That
- file is the last file whose source text was printed. This
- breakpoint will stop your program just before it executes any of
- the code on that line.
-
-`break FILENAME:LINENUM'
- Set a breakpoint at line LINENUM in source file FILENAME.
-
-`break FILENAME:FUNCTION'
- Set a breakpoint at entry to function FUNCTION found in file
- FILENAME. Specifying a file name as well as a function name is
- superfluous except when multiple files contain similarly named
- functions.
-
-`break *ADDRESS'
- Set a breakpoint at address ADDRESS. You can use this to set
- breakpoints in parts of your program which do not have debugging
- information or source files.
-
-`break'
- When called without any arguments, `break' sets a breakpoint at
- the next instruction to be executed in the selected stack frame
- (*note Examining the Stack: Stack.). In any selected frame but the
- innermost, this will cause your program to stop as soon as control
- returns to that frame. This is similar to the effect of a
- `finish' command in the frame inside the selected frame--except
- that `finish' does not leave an active breakpoint. If you use
- `break' without an argument in the innermost frame, GDB will stop
- the next time it reaches the current location; this may be useful
- inside loops.
-
- GDB normally ignores breakpoints when it resumes execution, until
- at least one instruction has been executed. If it did not do
- this, you would be unable to proceed past a breakpoint without
- first disabling the breakpoint. This rule applies whether or not
- the breakpoint already existed when your program stopped.
-
-`break ... if COND'
- Set a breakpoint with condition COND; evaluate the expression COND
- each time the breakpoint is reached, and stop only if the value is
- nonzero--that is, if COND evaluates as true. `...' stands for one
- of the possible arguments described above (or no argument)
- specifying where to break. *Note Break conditions: Conditions,
- for more information on breakpoint conditions.
-
-`tbreak ARGS'
- Set a breakpoint enabled only for one stop. ARGS are the same as
- for the `break' command, and the breakpoint is set in the same
- way, but the breakpoint is automatically disabled after the first
- time your program stops there. *Note Disabling breakpoints:
- Disabling.
-
-`rbreak REGEX'
- Set breakpoints on all functions matching the regular expression
- REGEX. This command sets an unconditional breakpoint on all
- matches, printing a list of all breakpoints it set. Once these
- breakpoints are set, they are treated just like the breakpoints
- set with the `break' command. They can be deleted, disabled, made
- conditional, etc., in the standard ways.
-
- When debugging C++ programs, `rbreak' is useful for setting
- breakpoints on overloaded functions that are not members of any
- special classes.
-
-`info breakpoints [N]'
-`info break [N]'
-`info watchpoints [N]'
- Print a table of all breakpoints and watchpoints set and not
- deleted, with the following columns for each breakpoint:
-
- *Breakpoint Numbers*
- *Type*
- Breakpoint or watchpoint.
-
- *Disposition*
- Whether the breakpoint is marked to be disabled or deleted
- when hit.
-
- *Enabled or Disabled*
- Enabled breakpoints are marked with `y'. `n' marks
- breakpoints that are not enabled.
-
- *Address*
- Where the breakpoint is in your program, as a memory address
-
- *What*
- Where the breakpoint is in the source for your program, as a
- file and line number.
-
- If a breakpoint is conditional, `info break' shows the condition on
- the line following the affected breakpoint; breakpoint commands,
- if any, are listed after that.
-
- `info break' with a breakpoint number N as argument lists only
- that breakpoint. The convenience variable `$_' and the default
- examining-address for the `x' command are set to the address of
- the last breakpoint listed (*note Examining memory: Memory.).
-
- GDB allows you to set any number of breakpoints at the same place in
-your program. There is nothing silly or meaningless about this. When
-the breakpoints are conditional, this is even useful (*note Break
-conditions: Conditions.).
-
- GDB itself sometimes sets breakpoints in your program for special
-purposes, such as proper handling of `longjmp' (in C programs). These
-internal breakpoints are assigned negative numbers, starting with `-1';
-`info breakpoints' does not display them.
-
- You can see these breakpoints with the GDB maintenance command
-`maint info breakpoints'.
-
-`maint info breakpoints'
- Using the same format as `info breakpoints', display both the
- breakpoints you've set explicitly, and those GDB is using for
- internal purposes. Internal breakpoints are shown with negative
- breakpoint numbers. The type column identifies what kind of
- breakpoint is shown:
-
- `breakpoint'
- Normal, explicitly set breakpoint.
-
- `watchpoint'
- Normal, explicitly set watchpoint.
-
- `longjmp'
- Internal breakpoint, used to handle correctly stepping through
- `longjmp' calls.
-
- `longjmp resume'
- Internal breakpoint at the target of a `longjmp'.
-
- `until'
- Temporary internal breakpoint used by the GDB `until' command.
-
- `finish'
- Temporary internal breakpoint used by the GDB `finish'
- command.

-
-Setting watchpoints
--------------------
-
- You can use a watchpoint to stop execution whenever the value of an
-expression changes, without having to predict a particular place where
-this may happen.
-
- Watchpoints currently execute two orders of magnitude more slowly
-than other breakpoints, but this can be well worth it to catch errors
-where you have no clue what part of your program is the culprit. Some
-processors provide special hardware to support watchpoint evaluation;
-future releases of GDB will use such hardware if it is available.
-
-`watch EXPR'
- Set a watchpoint for an expression.
-
-`info watchpoints'
- This command prints a list of watchpoints and breakpoints; it is
- the same as `info break'.
-
-
-File: gdb.info, Node: Exception Handling, Next: Delete Breaks, Prev: Set Watchpoints, Up: Breakpoints
-
-Breakpoints and exceptions
---------------------------
-
- Some languages, such as GNU C++, implement exception handling. You
-can use GDB to examine what caused your program to raise an exception,
-and to list the exceptions your program is prepared to handle at a
-given point in time.
-
-`catch EXCEPTIONS'
- You can set breakpoints at active exception handlers by using the
- `catch' command. EXCEPTIONS is a list of names of exceptions to
- catch.
-
- You can use `info catch' to list active exception handlers. *Note
-Information about a frame: Frame Info.
-
- There are currently some limitations to exception handling in GDB.
-These will be corrected in a future release.
-
- * If you call a function interactively, GDB normally returns control
- to you when the function has finished executing. If the call
- raises an exception, however, the call may bypass the mechanism
- that returns control to you and cause your program to simply
- continue running until it hits a breakpoint, catches a signal that
- GDB is listening for, or exits.
-
- * You cannot raise an exception interactively.
-
- * You cannot interactively install an exception handler.
-
- Sometimes `catch' is not the best way to debug exception handling:
-if you need to know exactly where an exception is raised, it is better
-to stop *before* the exception handler is called, since that way you
-can see the stack before any unwinding takes place. If you set a
-breakpoint in an exception handler instead, it may not be easy to find
-out where the exception was raised.
-
- To stop just before an exception handler is called, you need some
-knowledge of the implementation. In the case of GNU C++, exceptions are
-raised by calling a library function named `__raise_exception' which
-has the following ANSI C interface:
-
- /* ADDR is where the exception identifier is stored.
- ID is the exception identifier. */
- void __raise_exception (void **ADDR, void *ID);
-
-To make the debugger catch all exceptions before any stack unwinding
-takes place, set a breakpoint on `__raise_exception' (*note
-Breakpoints; watchpoints; and exceptions: Breakpoints.).
-
- With a conditional breakpoint (*note Break conditions: Conditions.)
-that depends on the value of ID, you can stop your program when a
-specific exception is raised. You can use multiple conditional
-breakpoints to stop your program when any of a number of exceptions are
-raised.
-
-
-File: gdb.info, Node: Delete Breaks, Next: Disabling, Prev: Exception Handling, Up: Breakpoints
-
-Deleting breakpoints
---------------------
-
- It is often necessary to eliminate a breakpoint or watchpoint once it
-has done its job and you no longer want your program to stop there.
-This is called "deleting" the breakpoint. A breakpoint that has been
-deleted no longer exists; it is forgotten.
-
- With the `clear' command you can delete breakpoints according to
-where they are in your program. With the `delete' command you can
-delete individual breakpoints or watchpoints by specifying their
-breakpoint numbers.
-
- It is not necessary to delete a breakpoint to proceed past it. GDB
-automatically ignores breakpoints on the first instruction to be
-executed when you continue execution without changing the execution
-address.
-
-`clear'
- Delete any breakpoints at the next instruction to be executed in
- the selected stack frame (*note Selecting a frame: Selection.).
- When the innermost frame is selected, this is a good way to delete
- a breakpoint where your program just stopped.
-
-`clear FUNCTION'
-`clear FILENAME:FUNCTION'
- Delete any breakpoints set at entry to the function FUNCTION.
-
-`clear LINENUM'
-`clear FILENAME:LINENUM'
- Delete any breakpoints set at or within the code of the specified
- line.
-
-`delete [breakpoints] [BNUMS...]'
- Delete the breakpoints or watchpoints of the numbers specified as
- arguments. If no argument is specified, delete all breakpoints
- (GDB asks confirmation, unless you have `set confirm off'). You
- can abbreviate this command as `d'.
-
-
-File: gdb.info, Node: Disabling, Next: Conditions, Prev: Delete Breaks, Up: Breakpoints
-
-Disabling breakpoints
----------------------
-
- Rather than deleting a breakpoint or watchpoint, you might prefer to
-"disable" it. This makes the breakpoint inoperative as if it had been
-deleted, but remembers the information on the breakpoint so that you
-can "enable" it again later.
-
- You disable and enable breakpoints and watchpoints with the `enable'
-and `disable' commands, optionally specifying one or more breakpoint
-numbers as arguments. Use `info break' or `info watch' to print a list
-of breakpoints or watchpoints if you do not know which numbers to use.
-
- A breakpoint or watchpoint can have any of four different states of
-enablement:
-
- * Enabled. The breakpoint will stop your program. A breakpoint set
- with the `break' command starts out in this state.
-
- * Disabled. The breakpoint has no effect on your program.
-
- * Enabled once. The breakpoint will stop your program, but when it
- does so it will become disabled. A breakpoint set with the
- `tbreak' command starts out in this state.
-
- * Enabled for deletion. The breakpoint will stop your program, but
- immediately after it does so it will be deleted permanently.
-
- You can use the following commands to enable or disable breakpoints
-and watchpoints:
-
-`disable [breakpoints] [BNUMS...]'
- Disable the specified breakpoints--or all breakpoints, if none are
- listed. A disabled breakpoint has no effect but is not forgotten.
- All options such as ignore-counts, conditions and commands are
- remembered in case the breakpoint is enabled again later. You may
- abbreviate `disable' as `dis'.
-
-`enable [breakpoints] [BNUMS...]'
- Enable the specified breakpoints (or all defined breakpoints).
- They become effective once again in stopping your program.
-
-`enable [breakpoints] once BNUMS...'
- Enable the specified breakpoints temporarily. Each will be
- disabled again the next time it stops your program.
-
-`enable [breakpoints] delete BNUMS...'
- Enable the specified breakpoints to work once and then die. Each
- of the breakpoints will be deleted the next time it stops your
- program.
-
- Save for a breakpoint set with `tbreak' (*note Setting breakpoints:
-Set Breaks.), breakpoints that you set are initially enabled;
-subsequently, they become disabled or enabled only when you use one of
-the commands above. (The command `until' can set and delete a
-breakpoint of its own, but it will not change the state of your other
-breakpoints; see *Note Continuing and stepping: Continuing and
-Stepping.)

-
-Break conditions
-----------------
-
- The simplest sort of breakpoint breaks every time your program
-reaches a specified place. You can also specify a "condition" for a
-breakpoint. A condition is just a Boolean expression in your
-programming language (*note Expressions: Expressions.). A breakpoint
-with a condition evaluates the expression each time your program
-reaches it, and your program stops only if the condition is *true*.
-
- This is the converse of using assertions for program validation; in
-that situation, you want to stop when the assertion is violated--that
-is, when the condition is false. In C, if you want to test an
-assertion expressed by the condition ASSERT, you should set the
-condition `! ASSERT' on the appropriate breakpoint.
-
- Conditions are also accepted for watchpoints; you may not need them,
-since a watchpoint is inspecting the value of an expression anyhow--but
-it might be simpler, say, to just set a watchpoint on a variable name,
-and specify a condition that tests whether the new value is an
-interesting one.
-
- Break conditions can have side effects, and may even call functions
-in your program. This can be useful, for example, to activate functions
-that log program progress, or to use your own print functions to format
-special data structures. The effects are completely predictable unless
-there is another enabled breakpoint at the same address. (In that
-case, GDB might see the other breakpoint first and stop your program
-without checking the condition of this one.) Note that breakpoint
-commands are usually more convenient and flexible for the purpose of
-performing side effects when a breakpoint is reached (*note Breakpoint
-command lists: Break Commands.).
-
- Break conditions can be specified when a breakpoint is set, by using
-`if' in the arguments to the `break' command. *Note Setting
-breakpoints: Set Breaks. They can also be changed at any time with the
-`condition' command. The `watch' command does not recognize the `if'
-keyword; `condition' is the only way to impose a further condition on a
-watchpoint.
-
-`condition BNUM EXPRESSION'
- Specify EXPRESSION as the break condition for breakpoint or
- watchpoint number BNUM. From now on, this breakpoint will stop
- your program only if the value of EXPRESSION is true (nonzero, in
- C). When you use `condition', GDB checks EXPRESSION immediately
- for syntactic correctness, and to determine whether symbols in it
- have referents in the context of your breakpoint. GDB does not
- actually evaluate EXPRESSION at the time the `condition' command
- is given, however. *Note Expressions: Expressions.
-
-`condition BNUM'
- Remove the condition from breakpoint number BNUM. It becomes an
- ordinary unconditional breakpoint.
-
- A special case of a breakpoint condition is to stop only when the
-breakpoint has been reached a certain number of times. This is so
-useful that there is a special way to do it, using the "ignore count"
-of the breakpoint. Every breakpoint has an ignore count, which is an
-integer. Most of the time, the ignore count is zero, and therefore has
-no effect. But if your program reaches a breakpoint whose ignore count
-is positive, then instead of stopping, it just decrements the ignore
-count by one and continues. As a result, if the ignore count value is
-N, the breakpoint will not stop the next N times it is reached.
-
-`ignore BNUM COUNT'
- Set the ignore count of breakpoint number BNUM to COUNT. The next
- COUNT times the breakpoint is reached, your program's execution
- will not stop; other than to decrement the ignore count, GDB takes
- no action.
-
- To make the breakpoint stop the next time it is reached, specify a
- count of zero.
-
- When you use `continue' to resume execution of your program from a
- breakpoint, you can specify an ignore count directly as an
- argument to `continue', rather than using `ignore'. *Note
- Continuing and stepping: Continuing and Stepping.
-
- If a breakpoint has a positive ignore count and a condition, the
- condition is not checked. Once the ignore count reaches zero, the
- condition will be checked.
-
- You could achieve the effect of the ignore count with a condition
- such as `$foo-- <= 0' using a debugger convenience variable that
- is decremented each time. *Note Convenience variables:
- Convenience Vars.

-Breakpoint command lists
-------------------------
-
- You can give any breakpoint (or watchpoint) a series of commands to
-execute when your program stops due to that breakpoint. For example,
-you might want to print the values of certain expressions, or enable
-other breakpoints.
-
-`commands [BNUM]'
-`... COMMAND-LIST ...'
-`end'
- Specify a list of commands for breakpoint number BNUM. The
- commands themselves appear on the following lines. Type a line
- containing just `end' to terminate the commands.
-
- To remove all commands from a breakpoint, type `commands' and
- follow it immediately with `end'; that is, give no commands.
-
- With no BNUM argument, `commands' refers to the last breakpoint or
- watchpoint set (not to the breakpoint most recently encountered).
-
- Pressing RET as a means of repeating the last GDB command is
-disabled within a COMMAND-LIST.
-
- You can use breakpoint commands to start your program up again.
-Simply use the `continue' command, or `step', or any other command that
-resumes execution.
-
- Any other commands in the command list, after a command that resumes
-execution, are ignored. This is because any time you resume execution
-(even with a simple `next' or `step'), you may encounter another
-breakpoint--which could have its own command list, leading to
-ambiguities about which list to execute.
-
- If the first command you specify in a command list is `silent', the
-usual message about stopping at a breakpoint is not printed. This may
-be desirable for breakpoints that are to print a specific message and
-then continue. If none of the remaining commands print anything, you
-will see no sign that the breakpoint was reached. `silent' is
-meaningful only at the beginning of a breakpoint command list.
-
- The commands `echo', `output', and `printf' allow you to print
-precisely controlled output, and are often useful in silent
-breakpoints. *Note Commands for controlled output: Output.
-
- For example, here is how you could use breakpoint commands to print
-the value of `x' at entry to `foo' whenever `x' is positive.
-
- break foo if x>0
- commands
- silent
- printf "x is %d\n",x
- cont
- end
-
- One application for breakpoint commands is to compensate for one bug
-so you can test for another. Put a breakpoint just after the erroneous
-line of code, give it a condition to detect the case in which something
-erroneous has been done, and give it commands to assign correct values
-to any variables that need them. End with the `continue' command so
-that your program does not stop, and start with the `silent' command so
-that no output is produced. Here is an example:
-
- break 403
- commands
- silent
- set x = y + 4
- cont
- end

-Breakpoint menus
-----------------
-
- Some programming languages (notably C++) permit a single function
-name to be defined several times, for application in different contexts.
-This is called "overloading". When a function name is overloaded,
-`break FUNCTION' is not enough to tell GDB where you want a breakpoint.
-If you realize this will be a problem, you can use something like
-`break FUNCTION(TYPES)' to specify which particular version of the
-function you want. Otherwise, GDB offers you a menu of numbered
-choices for different possible breakpoints, and waits for your
-selection with the prompt `>'. The first two options are always `[0]
-cancel' and `[1] all'. Typing `1' sets a breakpoint at each definition
-of FUNCTION, and typing `0' aborts the `break' command without setting
-any new breakpoints.
-
- For example, the following session excerpt shows an attempt to set a
-breakpoint at the overloaded symbol `String::after'. We choose three
-particular definitions of that function name:
-
- (gdb) b String::after
- [0] cancel
- [1] all
- [2] file:String.cc; line number:867
- [3] file:String.cc; line number:860
- [4] file:String.cc; line number:875
- [5] file:String.cc; line number:853
- [6] file:String.cc; line number:846
- [7] file:String.cc; line number:735
- > 2 4 6
- Breakpoint 1 at 0xb26c: file String.cc, line 867.
- Breakpoint 2 at 0xb344: file String.cc, line 875.
- Breakpoint 3 at 0xafcc: file String.cc, line 846.
- Multiple breakpoints were set.
- Use the "delete" command to delete unwanted
- breakpoints.

-"Cannot insert breakpoints"
----------------------------
-
- Under some operating systems, breakpoints cannot be used in a
-program if any other process is running that program. In this
-situation, attempting to run or continue a program with a breakpoint
-causes GDB to stop the other process.
-
- When this happens, you have three ways to proceed:
-
- 1. Remove or disable the breakpoints, then continue.
-
- 2. Suspend GDB, and copy the file containing your program to a new
- name. Resume GDB and use the `exec-file' command to specify that
- GDB should run your program under that name. Then start your
- program again.
-
- 3. Relink your program so that the text segment is nonsharable, using
- the linker option `-N'. The operating system limitation may not
- apply to nonsharable executables.

-
-Continuing and stepping
-=======================
-
- "Continuing" means resuming program execution until your program
-completes normally. In contrast, "stepping" means executing just one
-more "step" of your program, where "step" may mean either one line of
-source code, or one machine instruction (depending on what particular
-command you use). Either when continuing or when stepping, your
-program may stop even sooner, due to a breakpoint or a signal. (If due
-to a signal, you may want to use `handle', or use `signal 0' to resume
-execution. *Note Signals: Signals.)
-
-`continue [IGNORE-COUNT]'
-`c [IGNORE-COUNT]'
-`fg [IGNORE-COUNT]'
- Resume program execution, at the address where your program last
- stopped; any breakpoints set at that address are bypassed. The
- optional argument IGNORE-COUNT allows you to specify a further
- number of times to ignore a breakpoint at this location; its
- effect is like that of `ignore' (*note Break conditions:
- Conditions.).
-
- The argument IGNORE-COUNT is meaningful only when your program
- stopped due to a breakpoint. At other times, the argument to
- `continue' is ignored.
-
- The synonyms `c' and `fg' are provided purely for convenience, and
- have exactly the same behavior as `continue'.
-
- To resume execution at a different place, you can use `return'
-(*note Returning from a function: Returning.) to go back to the calling
-function; or `jump' (*note Continuing at a different address: Jumping.)
-to go to an arbitrary location in your program.
-
- A typical technique for using stepping is to set a breakpoint (*note
-Breakpoints; watchpoints; and exceptions: Breakpoints.) at the
-beginning of the function or the section of your program where a
-problem is believed to lie, run your program until it stops at that
-breakpoint, and then step through the suspect area, examining the
-variables that are interesting, until you see the problem happen.
-
-`step'
- Continue running your program until control reaches a different
- source line, then stop it and return control to GDB. This command
- is abbreviated `s'.
-
- *Warning:* If you use the `step' command while control is
- within a function that was compiled without debugging
- information, execution proceeds until control reaches a
- function that does have debugging information.
-
-`step COUNT'
- Continue running as in `step', but do so COUNT times. If a
- breakpoint is reached, or a signal not related to stepping occurs
- before COUNT steps, stepping stops right away.
-
-`next [COUNT]'
- Continue to the next source line in the current (innermost) stack
- frame. Similar to `step', but any function calls appearing within
- the line of code are executed without stopping. Execution stops
- when control reaches a different line of code at the stack level
- which was executing when the `next' command was given. This
- command is abbreviated `n'.
-
- An argument COUNT is a repeat count, as for `step'.
-
- `next' within a function that lacks debugging information acts like
- `step', but any function calls appearing within the code of the
- function are executed without stopping.
-
-`finish'
- Continue running until just after function in the selected stack
- frame returns. Print the returned value (if any).
-
- Contrast this with the `return' command (*note Returning from a
- function: Returning.).
-
-`until'
-`u'
- Continue running until a source line past the current line, in the
- current stack frame, is reached. This command is used to avoid
- single stepping through a loop more than once. It is like the
- `next' command, except that when `until' encounters a jump, it
- automatically continues execution until the program counter is
- greater than the address of the jump.
-
- This means that when you reach the end of a loop after single
- stepping though it, `until' will cause your program to continue
- execution until the loop is exited. In contrast, a `next' command
- at the end of a loop will simply step back to the beginning of the
- loop, which would force you to step through the next iteration.
-
- `until' always stops your program if it attempts to exit the
- current stack frame.
-
- `until' may produce somewhat counterintuitive results if the order
- of machine code does not match the order of the source lines. For
- example, in the following excerpt from a debugging session, the `f'
- (`frame') command shows that execution is stopped at line `206';
- yet when we use `until', we get to line `195':
-
- (gdb) f
- #0 main (argc=4, argv=0xf7fffae8) at m4.c:206
- 206 expand_input();
- (gdb) until
- 195 for ( ; argc > 0; NEXTARG) {
-
- This happened because, for execution efficiency, the compiler had
- generated code for the loop closure test at the end, rather than
- the start, of the loop--even though the test in a C `for'-loop is
- written before the body of the loop. The `until' command appeared
- to step back to the beginning of the loop when it advanced to this
- expression; however, it has not really gone to an earlier
- statement--not in terms of the actual machine code.
-
- `until' with no argument works by means of single instruction
- stepping, and hence is slower than `until' with an argument.
-
-`until LOCATION'
-`u LOCATION'
- Continue running your program until either the specified location
- is reached, or the current stack frame returns. LOCATION is any of
- the forms of argument acceptable to `break' (*note Setting
- breakpoints: Set Breaks.). This form of the command uses
- breakpoints, and hence is quicker than `until' without an argument.
-
-`stepi'
-`si'
- Execute one machine instruction, then stop and return to the
- debugger.
-
- It is often useful to do `display/i $pc' when stepping by machine
- instructions. This will cause the next instruction to be executed
- to be displayed automatically at each stop. *Note Automatic
- display: Auto Display.
-
- An argument is a repeat count, as in `step'.
-
-`nexti'
-`ni'
- Execute one machine instruction, but if it is a function call,
- proceed until the function returns.
-
- An argument is a repeat count, as in `next'.
-
-
-File: gdb.info, Node: Signals, Prev: Continuing and Stepping, Up: Stopping
-
-Signals
-=======
-
- A signal is an asynchronous event that can happen in a program. The
-operating system defines the possible kinds of signals, and gives each
-kind a name and a number. For example, in Unix `SIGINT' is the signal
-a program gets when you type an interrupt (often `C-c'); `SIGSEGV' is
-the signal a program gets from referencing a place in memory far away
-from all the areas in use; `SIGALRM' occurs when the alarm clock timer
-goes off (which happens only if your program has requested an alarm).
-
- Some signals, including `SIGALRM', are a normal part of the
-functioning of your program. Others, such as `SIGSEGV', indicate
-errors; these signals are "fatal" (kill your program immediately) if the
-program has not specified in advance some other way to handle the
-signal. `SIGINT' does not indicate an error in your program, but it is
-normally fatal so it can carry out the purpose of the interrupt: to
-kill the program.
-
- GDB has the ability to detect any occurrence of a signal in your
-program. You can tell GDB in advance what to do for each kind of
-signal.
-
- Normally, GDB is set up to ignore non-erroneous signals like
-`SIGALRM' (so as not to interfere with their role in the functioning of
-your program) but to stop your program immediately whenever an error
-signal happens. You can change these settings with the `handle'
-command.
-
-`info signals'
- Print a table of all the kinds of signals and how GDB has been
- told to handle each one. You can use this to see the signal
- numbers of all the defined types of signals.
-
-`handle SIGNAL KEYWORDS...'
- Change the way GDB handles signal SIGNAL. SIGNAL can be the
- number of a signal or its name (with or without the `SIG' at the
- beginning). The KEYWORDS say what change to make.
-
- The keywords allowed by the `handle' command can be abbreviated.
-Their full names are:
-
-`nostop'
- GDB should not stop your program when this signal happens. It may
- still print a message telling you that the signal has come in.
-
-`stop'
- GDB should stop your program when this signal happens. This
- implies the `print' keyword as well.
-
-`print'
- GDB should print a message when this signal happens.
-
-`noprint'
- GDB should not mention the occurrence of the signal at all. This
- implies the `nostop' keyword as well.
-
-`pass'
- GDB should allow your program to see this signal; your program
- will be able to handle the signal, or may be terminated if the
- signal is fatal and not handled.
-
-`nopass'
- GDB should not allow your program to see this signal.
-
- When a signal stops your program, the signal is not visible until you
-continue. Your program will see the signal then, if `pass' is in
-effect for the signal in question *at that time*. In other words,
-after GDB reports a signal, you can use the `handle' command with
-`pass' or `nopass' to control whether that signal will be seen by your
-program when you later continue it.
-
- You can also use the `signal' command to prevent your program from
-seeing a signal, or cause it to see a signal it normally would not see,
-or to give it any signal at any time. For example, if your program
-stopped due to some sort of memory reference error, you might store
-correct values into the erroneous variables and continue, hoping to see
-more execution; but your program would probably terminate immediately as
-a result of the fatal signal once it saw the signal. To prevent this,
-you can continue with `signal 0'. *Note Giving your program a signal:
-Signaling.

-
-Examining the Stack
-*******************
-
- When your program has stopped, the first thing you need to know is
-where it stopped and how it got there.
-
- Each time your program performs a function call, the information
-about where in your program the call was made from is saved in a block
-of data called a "stack frame". The frame also contains the arguments
-of the call and the local variables of the function that was called.
-All the stack frames are allocated in a region of memory called the
-"call stack".
-
- When your program stops, the GDB commands for examining the stack
-allow you to see all of this information.
-
- One of the stack frames is "selected" by GDB and many GDB commands
-refer implicitly to the selected frame. In particular, whenever you
-ask GDB for the value of a variable in your program, the value is found
-in the selected frame. There are special GDB commands to select
-whichever frame you are interested in.
-
- When your program stops, GDB automatically selects the currently
-executing frame and describes it briefly as the `frame' command does
-(*note Information about a frame: Frame Info.).

-
-Stack frames
-============
-
- The call stack is divided up into contiguous pieces called "stack
-frames", or "frames" for short; each frame is the data associated with
-one call to one function. The frame contains the arguments given to
-the function, the function's local variables, and the address at which
-the function is executing.
-
- When your program is started, the stack has only one frame, that of
-the function `main'. This is called the "initial" frame or the
-"outermost" frame. Each time a function is called, a new frame is
-made. Each time a function returns, the frame for that function
-invocation is eliminated. If a function is recursive, there can be
-many frames for the same function. The frame for the function in which
-execution is actually occurring is called the "innermost" frame. This
-is the most recently created of all the stack frames that still exist.
-
- Inside your program, stack frames are identified by their addresses.
-A stack frame consists of many bytes, each of which has its own
-address; each kind of computer has a convention for choosing one of
-those bytes whose address serves as the address of the frame. Usually
-this address is kept in a register called the "frame pointer register"
-while execution is going on in that frame.
-
- GDB assigns numbers to all existing stack frames, starting with zero
-for the innermost frame, one for the frame that called it, and so on
-upward. These numbers do not really exist in your program; they are
-assigned by GDB to give you a way of designating stack frames in GDB
-commands.
-
- Some compilers provide a way to compile functions so that they
-operate without stack frames. (For example, the `gcc' option
-`-fomit-frame-pointer' will generate functions without a frame.) This
-is occasionally done with heavily used library functions to save the
-frame setup time. GDB has limited facilities for dealing with these
-function invocations. If the innermost function invocation has no
-stack frame, GDB will nevertheless regard it as though it had a
-separate frame, which is numbered zero as usual, allowing correct
-tracing of the function call chain. However, GDB has no provision for
-frameless functions elsewhere in the stack.

-
-Backtraces
-==========
-
- A backtrace is a summary of how your program got where it is. It
-shows one line per frame, for many frames, starting with the currently
-executing frame (frame zero), followed by its caller (frame one), and
-on up the stack.
-
-`backtrace'
-`bt'
- Print a backtrace of the entire stack: one line per frame for all
- frames in the stack.
-
- You can stop the backtrace at any time by typing the system
- interrupt character, normally `C-c'.
-
-`backtrace N'
-`bt N'
- Similar, but print only the innermost N frames.
-
-`backtrace -N'
-`bt -N'
- Similar, but print only the outermost N frames.
-
- The names `where' and `info stack' (abbreviated `info s') are
-additional aliases for `backtrace'.
-
- Each line in the backtrace shows the frame number and the function
-name. The program counter value is also shown--unless you use `set
-print address off'. The backtrace also shows the source file name and
-line number, as well as the arguments to the function. The program
-counter value is omitted if it is at the beginning of the code for that
-line number.
-
- Here is an example of a backtrace. It was made with the command `bt
-3', so it shows the innermost three frames.
-
- #0 m4_traceon (obs=0x24eb0, argc=1, argv=0x2b8c8)
- at builtin.c:993
- #1 0x6e38 in expand_macro (sym=0x2b600) at macro.c:242
- #2 0x6840 in expand_token (obs=0x0, t=177664, td=0xf7fffb08)
- at macro.c:71
- (More stack frames follow...)
-
-The display for frame zero does not begin with a program counter value,
-indicating that your program has stopped at the beginning of the code
-for line `993' of `builtin.c'.

-Selecting a frame
-=================
-
- Most commands for examining the stack and other data in your program
-work on whichever stack frame is selected at the moment. Here are the
-commands for selecting a stack frame; all of them finish by printing a
-brief description of the stack frame just selected.
-
-`frame N'
-`f N'
- Select frame number N. Recall that frame zero is the innermost
- (currently executing) frame, frame one is the frame that called the
- innermost one, and so on. The highest-numbered frame is the one
- for `main'.
-
-`frame ADDR'
-`f ADDR'
- Select the frame at address ADDR. This is useful mainly if the
- chaining of stack frames has been damaged by a bug, making it
- impossible for GDB to assign numbers properly to all frames. In
- addition, this can be useful when your program has multiple stacks
- and switches between them.
-
- On the SPARC architecture, `frame' needs two addresses to select
- an arbitrary frame: a frame pointer and a stack pointer.
-
-`up N'
- Move N frames up the stack. For positive numbers N, this advances
- toward the outermost frame, to higher frame numbers, to frames
- that have existed longer. N defaults to one.
-
-`down N'
- Move N frames down the stack. For positive numbers N, this
- advances toward the innermost frame, to lower frame numbers, to
- frames that were created more recently. N defaults to one. You
- may abbreviate `down' as `do'.
-
- All of these commands end by printing two lines of output describing
-the frame. The first line shows the frame number, the function name,
-the arguments, and the source file and line number of execution in that
-frame. The second line shows the text of that source line.
-
- For example:
- (gdb) up
- #1 0x22f0 in main (argc=1, argv=0xf7fffbf4, env=0xf7fffbfc)
- at env.c:10
- 10 read_input_file (argv[i]);
-
- After such a printout, the `list' command with no arguments will
-print ten lines centered on the point of execution in the frame. *Note
-Printing source lines: List.
-
-`up-silently N'
-`down-silently N'
- These two commands are variants of `up' and `down', respectively;
- they differ in that they do their work silently, without causing
- display of the new frame. They are intended primarily for use in
- GDB command scripts, where the output might be unnecessary and
- distracting.
-

-
-Information about a frame
-=========================
-
- There are several other commands to print information about the
-selected stack frame.
-
-`frame'
-`f'
- When used without any argument, this command does not change which
- frame is selected, but prints a brief description of the currently
- selected stack frame. It can be abbreviated `f'. With an
- argument, this command is used to select a stack frame. *Note
- Selecting a frame: Selection.
-
-`info frame'
-`info f'
- This command prints a verbose description of the selected stack
- frame, including the address of the frame, the addresses of the
- next frame down (called by this frame) and the next frame up
- (caller of this frame), the language that the source code
- corresponding to this frame was written in, the address of the
- frame's arguments, the program counter saved in it (the address of
- execution in the caller frame), and which registers were saved in
- the frame. The verbose description is useful when something has
- gone wrong that has made the stack format fail to fit the usual
- conventions.
-
-`info frame ADDR'
-`info f ADDR'
- Print a verbose description of the frame at address ADDR, without
- selecting that frame. The selected frame remains unchanged by
- this command.
-
-`info args'
- Print the arguments of the selected frame, each on a separate line.
-
-`info locals'
- Print the local variables of the selected frame, each on a separate
- line. These are all variables (declared either static or
- automatic) accessible at the point of execution of the selected
- frame.
-
-`info catch'
- Print a list of all the exception handlers that are active in the
- current stack frame at the current point of execution. To see
- other exception handlers, visit the associated frame (using the
- `up', `down', or `frame' commands); then type `info catch'. *Note
- Breakpoints and exceptions: Exception Handling.

-
-MIPS machines and the function stack
-====================================
-
- MIPS based computers use an unusual stack frame, which sometimes
-requires GDB to search backward in the object code to find the
-beginning of a function.
-
- To improve response time (especially for embedded applications, where
-GDB may be restricted to a slow serial line for this search) you may
-want to limit the size of this search, using one of these commands:
-
-`set heuristic-fence-post LIMIT'
- Restrict GDBN to examining at most LIMIT bytes in its search for
- the beginning of a function. A value of `0' (the default) means
- there is no limit.
-
-`show heuristic-fence-post'
- Display the current limit.
-
-These commands are available *only* when GDB is configured for
-debugging programs on MIPS processors.

-Examining Source Files
-**********************
-
- GDB can print parts of your program's source, since the debugging
-information recorded in the program tells GDB what source files were
-used to build it. When your program stops, GDB spontaneously prints
-the line where it stopped. Likewise, when you select a stack frame
-(*note Selecting a frame: Selection.), GDB prints the line where
-execution in that frame has stopped. You can print other portions of
-source files by explicit command.
-
- If you use GDB through its GNU Emacs interface, you may prefer to use
-Emacs facilities to view source; *note Using GDB under GNU Emacs:

-Printing source lines
-=====================
-
- To print lines from a source file, use the `list' command
-(abbreviated `l'). There are several ways to specify what part of the
-file you want to print.
-
- Here are the forms of the `list' command most commonly used:
-
-`list LINENUM'
- Print lines centered around line number LINENUM in the current
- source file.
-
-`list FUNCTION'
- Print lines centered around the beginning of function FUNCTION.
-
-`list'
- Print more lines. If the last lines printed were printed with a
- `list' command, this prints lines following the last lines
- printed; however, if the last line printed was a solitary line
- printed as part of displaying a stack frame (*note Examining the
- Stack: Stack.), this prints lines centered around that line.
-
-`list -'
- Print lines just before the lines last printed.
-
- By default, GDB prints ten source lines with any of these forms of
-the `list' command. You can change this using `set listsize':
-
-`set listsize COUNT'
- Make the `list' command display COUNT source lines (unless the
- `list' argument explicitly specifies some other number).
-
-`show listsize'
- Display the number of lines that `list' will currently display by
- default.
-
- Repeating a `list' command with RET discards the argument, so it is
-equivalent to typing just `list'. This is more useful than listing the
-same lines again. An exception is made for an argument of `-'; that
-argument is preserved in repetition so that each repetition moves up in
-the source file.
-
- In general, the `list' command expects you to supply zero, one or two
-"linespecs". Linespecs specify source lines; there are several ways of
-writing them but the effect is always to specify some source line.
-Here is a complete description of the possible arguments for `list':
-
-`list LINESPEC'
- Print lines centered around the line specified by LINESPEC.
-
-`list FIRST,LAST'
- Print lines from FIRST to LAST. Both arguments are linespecs.
-
-`list ,LAST'
- Print lines ending with LAST.
-
-`list FIRST,'
- Print lines starting with FIRST.
-
-`list +'
- Print lines just after the lines last printed.
-
-`list -'
- Print lines just before the lines last printed.
-
-`list'
- As described in the preceding table.
-
- Here are the ways of specifying a single source line--all the kinds
-of linespec.
-
-`NUMBER'
- Specifies line NUMBER of the current source file. When a `list'
- command has two linespecs, this refers to the same source file as
- the first linespec.
-
-`+OFFSET'
- Specifies the line OFFSET lines after the last line printed. When
- used as the second linespec in a `list' command that has two, this
- specifies the line OFFSET lines down from the first linespec.
-
-`-OFFSET'
- Specifies the line OFFSET lines before the last line printed.
-
-`FILENAME:NUMBER'
- Specifies line NUMBER in the source file FILENAME.
-
-`FUNCTION'
- Specifies the line of the open-brace that begins the body of the
- function FUNCTION.
-
-`FILENAME:FUNCTION'
- Specifies the line of the open-brace that begins the body of the
- function FUNCTION in the file FILENAME. You only need the file
- name with a function name to avoid ambiguity when there are
- identically named functions in different source files.
-
-`*ADDRESS'
- Specifies the line containing the program address ADDRESS.
- ADDRESS may be any expression.

-
-Searching source files
-======================
-
- There are two commands for searching through the current source file
-for a regular expression.
-
-`forward-search REGEXP'
-`search REGEXP'
- The command `forward-search REGEXP' checks each line, starting
- with the one following the last line listed, for a match for
- REGEXP. It lists the line that is found. You can use synonym
- `search REGEXP' or abbreviate the command name as `fo'.
-
-`reverse-search REGEXP'
- The command `reverse-search REGEXP' checks each line, starting
- with the one before the last line listed and going backward, for a
- match for REGEXP. It lists the line that is found. You can
- abbreviate this command as `rev'.
-
-

-
-Specifying source directories
-=============================
-
- Executable programs sometimes do not record the directories of the
-source files from which they were compiled, just the names. Even when
-they do, the directories could be moved between the compilation and
-your debugging session. GDB has a list of directories to search for
-source files; this is called the "source path". Each time GDB wants a
-source file, it tries all the directories in the list, in the order
-they are present in the list, until it finds a file with the desired
-name. Note that the executable search path is *not* used for this
-purpose. Neither is the current working directory, unless it happens
-to be in the source path.
-
- If GDB cannot find a source file in the source path, and the object
-program records a directory, GDB tries that directory too. If the
-source path is empty, and there is no record of the compilation
-directory, GDB will, as a last resort, look in the current directory.
-
- Whenever you reset or rearrange the source path, GDB will clear out
-any information it has cached about where source files are found, where
-each line is in the file, etc.
-
- When you start GDB, its source path is empty. To add other
-directories, use the `directory' command.
-
-`directory DIRNAME ...'
- Add directory DIRNAME to the front of the source path. Several
- directory names may be given to this command, separated by `:' or
- whitespace. You may specify a directory that is already in the
- source path; this moves it forward, so it will be searched sooner.
-
- You can use the string `$cdir' to refer to the compilation
- directory (if one is recorded), and `$cwd' to refer to the current
- working directory. `$cwd' is not the same as `.'--the former
- tracks the current working directory as it changes during your GDB
- session, while the latter is immediately expanded to the current
- directory at the time you add an entry to the source path.
-
-`directory'
- Reset the source path to empty again. This requires confirmation.
-
-`show directories'
- Print the source path: show which directories it contains.
-
- If your source path is cluttered with directories that are no longer
-of interest, GDB may sometimes cause confusion by finding the wrong
-versions of source. You can correct the situation as follows:
-
- 1. Use `directory' with no argument to reset the source path to empty.
-
- 2. Use `directory' with suitable arguments to reinstall the
- directories you want in the source path. You can add all the
- directories in one command.
-

-
-Source and machine code
-=======================
-
- You can use the command `info line' to map source lines to program
-addresses (and vice versa), and the command `disassemble' to display a
-range of addresses as machine instructions.
-
-`info line LINESPEC'
- Print the starting and ending addresses of the compiled code for
- source line LINESPEC. You can specify source lines in any of the
- ways understood by the `list' command (*note Printing source
- lines: List.).
-
- For example, we can use `info line' to discover the location of the
-object code for the first line of function `m4_changequote':
-
- (gdb) info line m4_changecom
- Line 895 of "builtin.c" starts at pc 0x634c and ends at 0x6350.
-
-We can also inquire (using `*ADDR' as the form for LINESPEC) what
-source line covers a particular address:
- (gdb) info line *0x63ff
- Line 926 of "builtin.c" starts at pc 0x63e4 and ends at 0x6404.
-
- After `info line', the default address for the `x' command is
-changed to the starting address of the line, so that `x/i' is
-sufficient to begin examining the machine code (*note Examining memory:
-Memory.). Also, this address is saved as the value of the convenience
-variable `$_' (*note Convenience variables: Convenience Vars.).
-
-`disassemble'
- This specialized command dumps a range of memory as machine
- instructions. The default memory range is the function
- surrounding the program counter of the selected frame. A single
- argument to this command is a program counter value; the function
- surrounding this value will be dumped. Two arguments specify a
- range of addresses (first inclusive, second exclusive) to dump.
-
- We can use `disassemble' to inspect the object code range shown in
-the last `info line' example (the example shows SPARC machine
-instructions):
-
- (gdb) disas 0x63e4 0x6404
- Dump of assembler code from 0x63e4 to 0x6404:
- 0x63e4 <builtin_init+5340>: ble 0x63f8 <builtin_init+5360>
- 0x63e8 <builtin_init+5344>: sethi %hi(0x4c00), %o0
- 0x63ec <builtin_init+5348>: ld [%i1+4], %o0
- 0x63f0 <builtin_init+5352>: b 0x63fc <builtin_init+5364>
- 0x63f4 <builtin_init+5356>: ld [%o0+4], %o0
- 0x63f8 <builtin_init+5360>: or %o0, 0x1a4, %o0
- 0x63fc <builtin_init+5364>: call 0x9288 <path_search>
- 0x6400 <builtin_init+5368>: nop
- End of assembler dump.

-Examining Data
-**************
-
- The usual way to examine data in your program is with the `print'
-command (abbreviated `p'), or its synonym `inspect'. It evaluates and
-prints the value of an expression of the language your program is
-written in (*note Using GDB with Different Languages: Languages.).
-
-`print EXP'
-`print /F EXP'
- EXP is an expression (in the source language). By default the
- value of EXP is printed in a format appropriate to its data type;
- you can choose a different format by specifying `/F', where F is a
- letter specifying the format; *note Output formats: Output
- Formats..
-
-`print'
-`print /F'
- If you omit EXP, GDB displays the last value again (from the
- "value history"; *note Value history: Value History.). This
- allows you to conveniently inspect the same value in an
- alternative format.
-
- A more low-level way of examining data is with the `x' command. It
-examines data in memory at a specified address and prints it in a
-specified format. *Note Examining memory: Memory.
-
- If you are interested in information about types, or about how the
-fields of a struct or class are declared, use the `ptype EXP' command
-rather than `print'. *Note Examining the Symbol Table: Symbols.

-Expressions
-===========
-
- `print' and many other GDB commands accept an expression and compute
-its value. Any kind of constant, variable or operator defined by the
-programming language you are using is valid in an expression in GDB.
-This includes conditional expressions, function calls, casts and string
-constants. It unfortunately does not include symbols defined by
-preprocessor `#define' commands.
-
- Because C is so widespread, most of the expressions shown in
-examples in this manual are in C. *Note Using GDB with Different
-Languages: Languages, for information on how to use expressions in other
-languages.
-
- In this section, we discuss operators that you can use in GDB
-expressions regardless of your programming language.
-
- Casts are supported in all languages, not just in C, because it is so
-useful to cast a number into a pointer so as to examine a structure at
-that address in memory.
-
- GDB supports these operators in addition to those of programming
-languages:
-
-`@'
- `@' is a binary operator for treating parts of memory as arrays.
- *Note Artificial arrays: Arrays, for more information.
-
-`::'
- `::' allows you to specify a variable in terms of the file or
- function where it is defined. *Note Program variables: Variables.
-
-`{TYPE} ADDR'
- Refers to an object of type TYPE stored at address ADDR in memory.
- ADDR may be any expression whose value is an integer or pointer
- (but parentheses are required around binary operators, just as in
- a cast). This construct is allowed regardless of what kind of
- data is normally supposed to reside at ADDR.
-
-
-File: gdb.info, Node: Variables, Next: Arrays, Prev: Expressions, Up: Data
-
-Program variables
-=================
-
- The most common kind of expression to use is the name of a variable
-in your program.
-
- Variables in expressions are understood in the selected stack frame
-(*note Selecting a frame: Selection.); they must either be global (or
-static) or be visible according to the scope rules of the programming
-language from the point of execution in that frame. This means that in
-the function
-
- foo (a)
- int a;
- {
- bar (a);
- {
- int b = test ();
- bar (b);
- }
- }
-
-you can examine and use the variable `a' whenever your program is
-executing within the function `foo', but you can only use or examine
-the variable `b' while your program is executing inside the block where
-`b' is declared.
-
- There is an exception: you can refer to a variable or function whose
-scope is a single source file even if the current execution point is not
-in this file. But it is possible to have more than one such variable or
-function with the same name (in different source files). If that
-happens, referring to that name has unpredictable effects. If you wish,
-you can specify a static variable in a particular function or file,
-using the colon-colon notation:
-
- FILE::VARIABLE
- FUNCTION::VARIABLE
-
-Here FILE or FUNCTION is the name of the context for the static
-VARIABLE. In the case of file names, you can use quotes to make sure
-GDB parses the file name as a single word--for example, to print a
-global value of `x' defined in `f2.c':
-
- (gdb) p 'f2.c'::x
-
- This use of `::' is very rarely in conflict with the very similar
-use of the same notation in C++. GDB also supports use of the C++
-scope resolution operator in GDB expressions.
-
- *Warning:* Occasionally, a local variable may appear to have the
- wrong value at certain points in a function--just after entry to a
- new scope, and just before exit.
- You may see this problem when you are stepping by machine
-instructions. This is because on most machines, it takes more than one
-instruction to set up a stack frame (including local variable
-definitions); if you are stepping by machine instructions, variables
-may appear to have the wrong values until the stack frame is completely
-built. On exit, it usually also takes more than one machine
-instruction to destroy a stack frame; after you begin stepping through
-that group of instructions, local variable definitions may be gone.

-
-Artificial arrays
-=================
-
- It is often useful to print out several successive objects of the
-same type in memory; a section of an array, or an array of dynamically
-determined size for which only a pointer exists in the program.
-
- You can do this by referring to a contiguous span of memory as an
-"artificial array", using the binary operator `@'. The left operand of
-`@' should be the first element of the desired array, as an individual
-object. The right operand should be the desired length of the array.
-The result is an array value whose elements are all of the type of the
-left argument. The first element is actually the left argument; the
-second element comes from bytes of memory immediately following those
-that hold the first element, and so on. Here is an example. If a
-program says
-
- int *array = (int *) malloc (len * sizeof (int));
-
-you can print the contents of `array' with
-
- p *array@len
-
- The left operand of `@' must reside in memory. Array values made
-with `@' in this way behave just like other arrays in terms of
-subscripting, and are coerced to pointers when used in expressions.
-Artificial arrays most often appear in expressions via the value history
-(*note Value history: Value History.), after printing one out.
-
- Sometimes the artificial array mechanism is not quite enough; in
-moderately complex data structures, the elements of interest may not
-actually be adjacent--for example, if you are interested in the values
-of pointers in an array. One useful work-around in this situation is
-to use a convenience variable (*note Convenience variables: Convenience
-Vars.) as a counter in an expression that prints the first interesting
-value, and then repeat that expression via RET. For instance, suppose
-you have an array `dtab' of pointers to structures, and you are
-interested in the values of a field `fv' in each structure. Here is an
-example of what you might type:
-
- set $i = 0
- p dtab[$i++]->fv
- RET
- RET
- ...
-
-

-
-Output formats
-==============
-
- By default, GDB prints a value according to its data type. Sometimes
-this is not what you want. For example, you might want to print a
-number in hex, or a pointer in decimal. Or you might want to view data
-in memory at a certain address as a character string or as an
-instruction. To do these things, specify an "output format" when you
-print a value.
-
- The simplest use of output formats is to say how to print a value
-already computed. This is done by starting the arguments of the
-`print' command with a slash and a format letter. The format letters
-supported are:
-
-`x'
- Regard the bits of the value as an integer, and print the integer
- in hexadecimal.
-
-`d'
- Print as integer in signed decimal.
-
-`u'
- Print as integer in unsigned decimal.
-
-`o'
- Print as integer in octal.
-
-`t'
- Print as integer in binary. The letter `t' stands for "two". (1)
-
-`a'
- Print as an address, both absolute in hex and as an offset from the
- nearest preceding symbol. This format can be used to discover
- where (in what function) an unknown address is located:
-
- (gdb) p/a 0x54320
- $3 = 0x54320 <_initialize_vx+396>
-
-`c'
- Regard as an integer and print it as a character constant.
-
-`f'
- Regard the bits of the value as a floating point number and print
- using typical floating point syntax.
-
- For example, to print the program counter in hex (*note
-Registers::.), type
-
- p/x $pc
-
-Note that no space is required before the slash; this is because command
-names in GDB cannot contain a slash.
-
- To reprint the last value in the value history with a different
-format, you can use the `print' command with just a format and no
-expression. For example, `p/x' reprints the last value in hex.
-
- ---------- Footnotes ----------
-
- (1) `b' cannot be used because these format letters are also used
-with the `x' command, where `b' stands for "byte"; *note Examining
-memory: Memory..
-
-
-File: gdb.info, Node: Memory, Next: Auto Display, Prev: Output Formats, Up: Data
-
-Examining memory
-================
-
- You can use the command `x' (for "examine") to examine memory in any
-of several formats, independently of your program's data types.
-
-`x/NFU ADDR'
-`x ADDR'
-`x'
- Use the `x' command to examine memory.
-
- N, F, and U are all optional parameters that specify how much memory
-to display and how to format it; ADDR is an expression giving the
-address where you want to start displaying memory. If you use defaults
-for NFU, you need not type the slash `/'. Several commands set
-convenient defaults for ADDR.
-
-N, the repeat count
- The repeat count is a decimal integer; the default is 1. It
- specifies how much memory (counting by units U) to display.
-
-F, the display format
- The display format is one of the formats used by `print', or `s'
- (null-terminated string) or `i' (machine instruction). The
- default is `x' (hexadecimal) initially, or the format from the
- last time you used either `x' or `print'.
-
-U, the unit size
- The unit size is any of
-
- `b'
- Bytes.
-
- `h'
- Halfwords (two bytes).
-
- `w'
- Words (four bytes). This is the initial default.
-
- `g'
- Giant words (eight bytes).
-
- Each time you specify a unit size with `x', that size becomes the
- default unit the next time you use `x'. (For the `s' and `i'
- formats, the unit size is ignored and is normally not written.)
-
-ADDR, starting display address
- ADDR is the address where you want GDB to begin displaying memory.
- The expression need not have a pointer value (though it may); it
- is always interpreted as an integer address of a byte of memory.
- *Note Expressions: Expressions, for more information on
- expressions. The default for ADDR is usually just after the last
- address examined--but several other commands also set the default
- address: `info breakpoints' (to the address of the last breakpoint
- listed), `info line' (to the starting address of a line), and
- `print' (if you use it to display a value from memory).
-
- For example, `x/3uh 0x54320' is a request to display three halfwords
-(`h') of memory, formatted as unsigned decimal integers (`u'), starting
-at address `0x54320'. `x/4xw $sp' prints the four words (`w') of
-memory above the stack pointer (here, `$sp'; *note Registers::.) in
-hexadecimal (`x').
-
- Since the letters indicating unit sizes are all distinct from the
-letters specifying output formats, you do not have to remember whether
-unit size or format comes first; either order will work. The output
-specifications `4xw' and `4wx' mean exactly the same thing. (However,
-the count N must come first; `wx4' will not work.)
-
- Even though the unit size U is ignored for the formats `s' and `i',
-you might still want to use a count N; for example, `3i' specifies that
-you want to see three machine instructions, including any operands.
-The command `disassemble' gives an alternative way of inspecting
-machine instructions; *note Source and machine code: Machine Code..
-
- All the defaults for the arguments to `x' are designed to make it
-easy to continue scanning memory with minimal specifications each time
-you use `x'. For example, after you have inspected three machine
-instructions with `x/3i ADDR', you can inspect the next seven with just
-`x/7'. If you use RET to repeat the `x' command, the repeat count N is
-used again; the other arguments default as for successive uses of `x'.
-
- The addresses and contents printed by the `x' command are not saved
-in the value history because there is often too much of them and they
-would get in the way. Instead, GDB makes these values available for
-subsequent use in expressions as values of the convenience variables
-`$_' and `$__'. After an `x' command, the last address examined is
-available for use in expressions in the convenience variable `$_'. The
-contents of that address, as examined, are available in the convenience
-variable `$__'.
-
- If the `x' command has a repeat count, the address and contents saved
-are from the last memory unit printed; this is not the same as the last
-address printed if several units were printed on the last line of
-output.
-
-
-File: gdb.info, Node: Auto Display, Next: Print Settings, Prev: Memory, Up: Data
-
-Automatic display
-=================
-
- If you find that you want to print the value of an expression
-frequently (to see how it changes), you might want to add it to the
-"automatic display list" so that GDB will print its value each time
-your program stops. Each expression added to the list is given a
-number to identify it; to remove an expression from the list, you
-specify that number. The automatic display looks like this:
-
- 2: foo = 38
- 3: bar[5] = (struct hack *) 0x3804
-
-This display shows item numbers, expressions and their current values.
-As with displays you request manually using `x' or `print', you can
-specify the output format you prefer; in fact, `display' decides
-whether to use `print' or `x' depending on how elaborate your format
-specification is--it uses `x' if you specify a unit size, or one of the
-two formats (`i' and `s') that are only supported by `x'; otherwise it
-uses `print'.
-
-`display EXP'
- Add the expression EXP to the list of expressions to display each
- time your program stops. *Note Expressions: Expressions.
-
- `display' will not repeat if you press RET again after using it.
-
-`display/FMT EXP'
- For FMT specifying only a display format and not a size or count,
- add the expression EXP to the auto-display list but arrange to
- display it each time in the specified format FMT. *Note Output
- formats: Output Formats.
-
-`display/FMT ADDR'
- For FMT `i' or `s', or including a unit-size or a number of units,
- add the expression ADDR as a memory address to be examined each
- time your program stops. Examining means in effect doing `x/FMT
- ADDR'. *Note Examining memory: Memory.
-
- For example, `display/i $pc' can be helpful, to see the machine
-instruction about to be executed each time execution stops (`$pc' is a
-common name for the program counter; *note Registers::.).
-
-`undisplay DNUMS...'
-`delete display DNUMS...'
- Remove item numbers DNUMS from the list of expressions to display.
-
- `undisplay' will not repeat if you press RET after using it.
- (Otherwise you would just get the error `No display number ...'.)
-
-`disable display DNUMS...'
- Disable the display of item numbers DNUMS. A disabled display
- item is not printed automatically, but is not forgotten. It may be
- enabled again later.
-
-`enable display DNUMS...'
- Enable display of item numbers DNUMS. It becomes effective once
- again in auto display of its expression, until you specify
- otherwise.
-
-`display'
- Display the current values of the expressions on the list, just as
- is done when your program stops.
-
-`info display'
- Print the list of expressions previously set up to display
- automatically, each one with its item number, but without showing
- the values. This includes disabled expressions, which are marked
- as such. It also includes expressions which would not be
- displayed right now because they refer to automatic variables not
- currently available.
-
- If a display expression refers to local variables, then it does not
-make sense outside the lexical context for which it was set up. Such an
-expression is disabled when execution enters a context where one of its
-variables is not defined. For example, if you give the command
-`display last_char' while inside a function with an argument
-`last_char', then this argument will be displayed while your program
-continues to stop inside that function. When it stops elsewhere--where
-there is no variable `last_char'--display is disabled. The next time
-your program stops where `last_char' is meaningful, you can enable the
-display expression once again.

-`set print address on'
- GDB will print memory addresses showing the location of stack
- traces, structure values, pointer values, breakpoints, and so
- forth, even when it also displays the contents of those addresses.
- The default is on. For example, this is what a stack frame
- display looks like, with `set print address on':
-
- (gdb) f
- #0 set_quotes (lq=0x34c78 "<<", rq=0x34c88 ">>")
- at input.c:530
- 530 if (lquote != def_lquote)
-
-`set print address off'
- Do not print addresses when displaying their contents. For
- example, this is the same stack frame displayed with `set print
- address off':
-
- (gdb) set print addr off
- (gdb) f
- #0 set_quotes (lq="<<", rq=">>") at input.c:530
- 530 if (lquote != def_lquote)
-
- You can use `set print address off' to eliminate all machine
- dependent displays from the GDB interface. For example, with
- `print address off', you should get the same text for backtraces on
- all machines--whether or not they involve pointer arguments.
-
-`show print address'
- Show whether or not addresses are to be printed.
-
- When GDB prints a symbolic address, it normally prints the closest
-earlier symbol plus an offset. If that symbol does not uniquely
-identify the address (for example, it is a name whose scope is a single
-source file), you may need to disambiguate. One way to do this is with
-`info line', for example `info line *0x4537'. Alternately, you can set
-GDB to print the source file and line number when it prints a symbolic
-address:
-
-`set print symbol-filename on'
- Tell GDB to print the source file name and line number of a symbol
- in the symbolic form of an address.
-
-`set print symbol-filename off'
- Do not print source file name and line number of a symbol. This
- is the default.
-
-`show print symbol-filename'
- Show whether or not GDB will print the source file name and line
- number of a symbol in the symbolic form of an address.
-
- Also, you may wish to see the symbolic form only if the address being
-printed is reasonably close to the closest earlier symbol:
-
-`set print max-symbolic-offset MAX-OFFSET'
- Tell GDB to only display the symbolic form of an address if the
- offset between the closest earlier symbol and the address is less
- than MAX-OFFSET. The default is 0, which means to always print the
- symbolic form of an address, if any symbol precedes it.
-
-`show print max-symbolic-offset'
- Ask how large the maximum offset is that GDB will print in a
- symbolic address.
-
-`set print array'
-`set print array on'
- GDB will pretty-print arrays. This format is more convenient to
- read, but uses more space. The default is off.
-
-`set print array off'
- Return to compressed format for arrays.
-
-`show print array'
- Show whether compressed or pretty format is selected for displaying
- arrays.
-
-`set print elements NUMBER-OF-ELEMENTS'
- If GDB is printing a large array, it will stop printing after it
- has printed the number of elements set by the `set print elements'
- command. This limit also applies to the display of strings.
- Setting the number of elements to zero means that the printing is
- unlimited.
-
-`show print elements'
- Display the number of elements of a large array that GDB will print
- before losing patience.
-
-`set print pretty on'
- Cause GDB to print structures in an indented format with one
- member per line, like this:
-
- $1 = {
- next = 0x0,
- flags = {
- sweet = 1,
- sour = 1
- },
- meat = 0x54 "Pork"
- }
-
-`set print pretty off'
- Cause GDB to print structures in a compact format, like this:
-
- $1 = {next = 0x0, flags = {sweet = 1, sour = 1}, \
- meat = 0x54 "Pork"}
-
- This is the default format.
-
-`show print pretty'
- Show which format GDB will use to print structures.
-
-`set print sevenbit-strings on'
- Print using only seven-bit characters; if this option is set, GDB
- will display any eight-bit characters (in strings or character
- values) using the notation `\'NNN. For example, `M-a' is
- displayed as `\341'.
-
-`set print sevenbit-strings off'
- Print using either seven-bit or eight-bit characters, as required.
- This is the default.
-
-`show print sevenbit-strings'
- Show whether or not GDB will print only seven-bit characters.
-
-`set print union on'
- Tell GDB to print unions which are contained in structures. This
- is the default setting.
-
-`set print union off'
- Tell GDB not to print unions which are contained in structures.
-
-`show print union'
- Ask GDB whether or not it will print unions which are contained in
- structures.
-
- For example, given the declarations
-
- typedef enum {Tree, Bug} Species;
- typedef enum {Big_tree, Acorn, Seedling} Tree_forms;
- typedef enum {Caterpillar, Cocoon, Butterfly}
- Bug_forms;
-
- struct thing {
- Species it;
- union {
- Tree_forms tree;
- Bug_forms bug;
- } form;
- };
-
- struct thing foo = {Tree, {Acorn}};
-
- with `set print union on' in effect `p foo' would print
-
- $1 = {it = Tree, form = {tree = Acorn, bug = Cocoon}}
-
- and with `set print union off' in effect it would print
-
- $1 = {it = Tree, form = {...}}
-
-These settings are of interest when debugging C++ programs:
-
-`set print demangle'
-`set print demangle on'
- Print C++ names in their source form rather than in the encoded
- ("mangled") form passed to the assembler and linker for type-safe
- linkage. The default is `on'.
-
-`show print demangle'
- Show whether C++ names will be printed in mangled or demangled
- form.
-
-`set print asm-demangle'
-`set print asm-demangle on'
- Print C++ names in their source form rather than their mangled
- form, even in assembler code printouts such as instruction
- disassemblies. The default is off.
-
-`show print asm-demangle'
- Show whether C++ names in assembly listings will be printed in
- mangled or demangled form.
-
-`set demangle-style STYLE'
- Choose among several encoding schemes used by different compilers
- to represent C++ names. The choices for STYLE are currently:
-
- `auto'
- Allow GDB to choose a decoding style by inspecting your
- program.
-
- `gnu'
- Decode based on the GNU C++ compiler (`g++') encoding
- algorithm.
-
- `lucid'
- Decode based on the Lucid C++ compiler (`lcc') encoding
- algorithm.
-
- `arm'
- Decode using the algorithm in the `C++ Annotated Reference
- Manual'. *Warning:* this setting alone is not sufficient to
- allow debugging `cfront'-generated executables. GDB would
- require further enhancement to permit that.
-
-`show demangle-style'
- Display the encoding style currently in use for decoding C++
- symbols.
-
-`set print object'
-`set print object on'
- When displaying a pointer to an object, identify the *actual*
- (derived) type of the object rather than the *declared* type, using
- the virtual function table.
-
-`set print object off'
- Display only the declared type of objects, without reference to the
- virtual function table. This is the default setting.
-
-`show print object'
- Show whether actual, or declared, object types will be displayed.
-
-`set print vtbl'
-`set print vtbl on'
- Pretty print C++ virtual function tables. The default is off.
-
-`set print vtbl off'
- Do not pretty print C++ virtual function tables.
-
-`show print vtbl'
- Show whether C++ virtual function tables are pretty printed, or
- not.

-
-Value history
-=============
-
- Values printed by the `print' command are saved in the GDB "value
-history" so that you can refer to them in other expressions. Values are
-kept until the symbol table is re-read or discarded (for example with
-the `file' or `symbol-file' commands). When the symbol table changes,
-the value history is discarded, since the values may contain pointers
-back to the types defined in the symbol table.
-
- The values printed are given "history numbers" by which you can
-refer to them. These are successive integers starting with one.
-`print' shows you the history number assigned to a value by printing
-`$NUM = ' before the value; here NUM is the history number.
-
- To refer to any previous value, use `$' followed by the value's
-history number. The way `print' labels its output is designed to
-remind you of this. Just `$' refers to the most recent value in the
-history, and `$$' refers to the value before that. `$$N' refers to the
-Nth value from the end; `$$2' is the value just prior to `$$', `$$1' is
-equivalent to `$$', and `$$0' is equivalent to `$'.
-
- For example, suppose you have just printed a pointer to a structure
-and want to see the contents of the structure. It suffices to type
-
- p *$
-
- If you have a chain of structures where the component `next' points
-to the next one, you can print the contents of the next one with this:
-
- p *$.next
-
-You can print successive links in the chain by repeating this
-command--which you can do by just typing RET.
-
- Note that the history records values, not expressions. If the value
-of `x' is 4 and you type these commands:
-
- print x
- set x=5
-
-then the value recorded in the value history by the `print' command
-remains 4 even though the value of `x' has changed.
-
-`show values'
- Print the last ten values in the value history, with their item
- numbers. This is like `p $$9' repeated ten times, except that
- `show values' does not change the history.
-
-`show values N'
- Print ten history values centered on history item number N.
-
-`show values +'
- Print ten history values just after the values last printed. If
- no more values are available, produces no display.
-
- Pressing RET to repeat `show values N' has exactly the same effect
-as `show values +'.

-
-Convenience variables
-=====================
-
- GDB provides "convenience variables" that you can use within GDB to
-hold on to a value and refer to it later. These variables exist
-entirely within GDB; they are not part of your program, and setting a
-convenience variable has no direct effect on further execution of your
-program. That is why you can use them freely.
-
- Convenience variables are prefixed with `$'. Any name preceded by
-`$' can be used for a convenience variable, unless it is one of the
-predefined machine-specific register names (*note Registers::.).
-(Value history references, in contrast, are *numbers* preceded by `$'.
-*Note Value history: Value History.)
-
- You can save a value in a convenience variable with an assignment
-expression, just as you would set a variable in your program. For
-example:
-
- set $foo = *object_ptr
-
-would save in `$foo' the value contained in the object pointed to by
-`object_ptr'.
-
- Using a convenience variable for the first time creates it, but its
-value is `void' until you assign a new value. You can alter the value
-with another assignment at any time.
-
- Convenience variables have no fixed types. You can assign a
-convenience variable any type of value, including structures and
-arrays, even if that variable already has a value of a different type.
-The convenience variable, when used as an expression, has the type of
-its current value.
-
-`show convenience'
- Print a list of convenience variables used so far, and their
- values. Abbreviated `show con'.
-
- One of the ways to use a convenience variable is as a counter to be
-incremented or a pointer to be advanced. For example, to print a field
-from successive elements of an array of structures:
-
- set $i = 0
- print bar[$i++]->contents
- ... repeat that command by typing RET.
-
- Some convenience variables are created automatically by GDB and given
-values likely to be useful.
-
-`$_'
- The variable `$_' is automatically set by the `x' command to the
- last address examined (*note Examining memory: Memory.). Other
- commands which provide a default address for `x' to examine also
- set `$_' to that address; these commands include `info line' and
- `info breakpoint'. The type of `$_' is `void *' except when set
- by the `x' command, in which case it is a pointer to the type of
- `$__'.
-
-`$__'
- The variable `$__' is automatically set by the `x' command to the
- value found in the last address examined. Its type is chosen to
- match the format in which the data was printed.

-
-Registers
-=========
-
- You can refer to machine register contents, in expressions, as
-variables with names starting with `$'. The names of registers are
-different for each machine; use `info registers' to see the names used
-on your machine.
-
-`info registers'
- Print the names and values of all registers except floating-point
- registers (in the selected stack frame).
-
-`info all-registers'
- Print the names and values of all registers, including
- floating-point registers.
-
-`info registers REGNAME ...'
- Print the relativized value of each specified register REGNAME.
- rEGNAME may be any register name valid on the machine you are
- using, with or without the initial `$'.
-
- GDB has four "standard" register names that are available (in
-expressions) on most machines--whenever they do not conflict with an
-architecture's canonical mnemonics for registers. The register names
-`$pc' and `$sp' are used for the program counter register and the stack
-pointer. `$fp' is used for a register that contains a pointer to the
-current stack frame, and `$ps' is used for a register that contains the
-processor status. For example, you could print the program counter in
-hex with
-
- p/x $pc
-
-or print the instruction to be executed next with
-
- x/i $pc
-
-or add four to the stack pointer(1) with
-
- set $sp += 4
-
- Whenever possible, these four standard register names are available
-on your machine even though the machine has different canonical
-mnemonics, so long as there is no conflict. The `info registers'
-command shows the canonical names. For example, on the SPARC, `info
-registers' displays the processor status register as `$psr' but you can
-also refer to it as `$ps'.
-
- GDB always considers the contents of an ordinary register as an
-integer when the register is examined in this way. Some machines have
-special registers which can hold nothing but floating point; these
-registers are considered to have floating point values. There is no way
-to refer to the contents of an ordinary register as floating point value
-(although you can *print* it as a floating point value with `print/f
-$REGNAME').
-
- Some registers have distinct "raw" and "virtual" data formats. This
-means that the data format in which the register contents are saved by
-the operating system is not the same one that your program normally
-sees. For example, the registers of the 68881 floating point
-coprocessor are always saved in "extended" (raw) format, but all C
-programs expect to work with "double" (virtual) format. In such cases,
-GDB normally works with the virtual format only (the format that makes
-sense for your program), but the `info registers' command prints the
-data in both formats.
-
- Normally, register values are relative to the selected stack frame
-(*note Selecting a frame: Selection.). This means that you get the
-value that the register would contain if all stack frames farther in
-were exited and their saved registers restored. In order to see the
-true contents of hardware registers, you must select the innermost
-frame (with `frame 0').
-
- However, GDB must deduce where registers are saved, from the machine
-code generated by your compiler. If some registers are not saved, or if
-GDB is unable to locate the saved registers, the selected stack frame
-will make no difference.
-
-`set rstack_high_address ADDRESS'
- On AMD 29000 family processors, registers are saved in a separate
- "register stack". There is no way for GDB to determine the extent
- of this stack. Normally, GDB just assumes that the stack is "large
- enough". This may result in GDB referencing memory locations that
- do not exist. If necessary, you can get around this problem by
- specifying the ending address of the register stack with the `set
- rstack_high_address' command. The argument should be an address,
- which you will probably want to precede with `0x' to specify in
- hexadecimal.
-
-`show rstack_high_address'
- Display the current limit of the register stack, on AMD 29000
- family processors.
-
- ---------- Footnotes ----------
-
- (1) This is a way of removing one word from the stack, on machines
-where stacks grow downward in memory (most machines, nowadays). This
-assumes that the innermost stack frame is selected; setting `$sp' is
-not allowed when other stack frames are selected. To pop entire frames
-off the stack, regardless of machine architecture, use `return'; *note
-Returning from a function: Returning..

-Using GDB with Different Languages
-**********************************
-
- Although programming languages generally have common aspects, they
-are rarely expressed in the same manner. For instance, in ANSI C,
-dereferencing a pointer `p' is accomplished by `*p', but in Modula-2,
-it is accomplished by `p^'. Values can also be represented (and
-displayed) differently. Hex numbers in C are written like `0x1ae',
-while in Modula-2 they appear as `1AEH'.
-
- Language-specific information is built into GDB for some languages,
-allowing you to express operations like the above in your program's
-native language, and allowing GDB to output values in a manner
-consistent with the syntax of your program's native language. The
-language you use to build expressions, called the "working language",
-can be selected manually, or GDB can set it automatically.

-
-Switching between source languages
-==================================
-
- There are two ways to control the working language--either have GDB
-set it automatically, or select it manually yourself. You can use the
-`set language' command for either purpose. On startup, GDB defaults to
-setting the language automatically.

-* Automatically:: Having GDB infer the source language
-
-

-
-Setting the working language
-----------------------------
-
- If you allow GDB to set the language automatically, expressions are
-interpreted the same way in your debugging session and your program.
-
- If you wish, you may set the language manually. To do this, issue
-the command `set language LANG', where LANG is the name of a language,
-such as `c' or `modula-2'. For a list of the supported languages, type
-`set language'.
-
- Setting the language manually prevents GDB from updating the working
-language automatically. This can lead to confusion if you try to debug
-a program when the working language is not the same as the source
-language, when an expression is acceptable to both languages--but means
-different things. For instance, if the current source file were
-written in C, and GDB was parsing Modula-2, a command such as:
-
- print a = b + c
-
-might not have the effect you intended. In C, this means to add `b'
-and `c' and place the result in `a'. The result printed would be the
-value of `a'. In Modula-2, this means to compare `a' to the result of
-`b+c', yielding a `BOOLEAN' value.
-
-
-File: gdb.info, Node: Automatically, Prev: Manually, Up: Setting
-
-Having GDB infer the source language
-------------------------------------
-
- To have GDB set the working language automatically, use `set
-language local' or `set language auto'. GDB then infers the language
-that a program was written in by looking at the name of its source
-files, and examining their extensions:
-
-`*.mod'
- Modula-2 source file
-
-`*.c'
- C source file
-
-`*.C'
-`*.cc'
- C++ source file
-
- This information is recorded for each function or procedure in a
-source file. When your program stops in a frame (usually by
-encountering a breakpoint), GDB sets the working language to the
-language recorded for the function in that frame. If the language for
-a frame is unknown (that is, if the function or block corresponding to
-the frame was defined in a source file that does not have a recognized
-extension), the current working language is not changed, and GDB issues
-a warning.
-
- This may not seem necessary for most programs, which are written
-entirely in one source language. However, program modules and libraries
-written in one source language can be used by a main program written in
-a different source language. Using `set language auto' in this case
-frees you from having to set the working language manually.
-
-

-
-Displaying the language
-=======================
-
- The following commands will help you find out which language is the
-working language, and also what language source files were written in.
-
-`show language'
- Display the current working language. This is the language you
- can use with commands such as `print' to build and compute
- expressions that may involve variables in your program.
-
-`info frame'
- Among the other information listed here (*note Information about a
- frame: Frame Info.) is the source language for this frame. This
- is the language that will become the working language if you ever
- use an identifier that is in this frame.
-
-`info source'
- Among the other information listed here (*note Examining the
- Symbol Table: Symbols.) is the source language of this source file.

-
-Type and range checking
-=======================
-
- *Warning:* In this release, the GDB commands for type and range
- checking are included, but they do not yet have any effect. This
- section documents the intended facilities.
-
- Some languages are designed to guard you against making seemingly
-common errors through a series of compile- and run-time checks. These
-include checking the type of arguments to functions and operators, and
-making sure mathematical overflows are caught at run time. Checks such
-as these help to ensure a program's correctness once it has been
-compiled by eliminating type mismatches, and providing active checks
-for range errors when your program is running.
-
- GDB can check for conditions like the above if you wish. Although
-GDB will not check the statements in your program, it can check
-expressions entered directly into GDB for evaluation via the `print'
-command, for example. As with the working language, GDB can also
-decide whether or not to check automatically based on your program's
-source language. *Note Supported languages: Support, for the default
-settings of supported languages.

-
-An overview of type checking
-----------------------------
-
- Some languages, such as Modula-2, are strongly typed, meaning that
-the arguments to operators and functions have to be of the correct type,
-otherwise an error occurs. These checks prevent type mismatch errors
-from ever causing any run-time problems. For example,
-
- 1 + 2 => 3
-but
- error--> 1 + 2.3
-
- The second example fails because the `CARDINAL' 1 is not
-type-compatible with the `REAL' 2.3.
-
- For expressions you use in GDB commands, you can tell the GDB type
-checker to skip checking; to treat any mismatches as errors and abandon
-the expression; or only issue warnings when type mismatches occur, but
-evaluate the expression anyway. When you choose the last of these, GDB
-evaluates expressions like the second example above, but also issues a
-warning.
-
- Even though you may turn type checking off, other type-based reasons
-may prevent GDB from evaluating an expression. For instance, GDB does
-not know how to add an `int' and a `struct foo'. These particular type
-errors have nothing to do with the language in use, and usually arise
-from expressions, such as the one described above, which make little
-sense to evaluate anyway.
-
- Each language defines to what degree it is strict about type. For
-instance, both Modula-2 and C require the arguments to arithmetical
-operators to be numbers. In C, enumerated types and pointers can be
-represented as numbers, so that they are valid arguments to mathematical
-operators. *Note Supported languages: Support, for further details on
-specific languages.
-
- GDB provides some additional commands for controlling the type
-checker:
-
-`set check type auto'
- Set type checking on or off based on the current working language.
- *Note Supported languages: Support, for the default settings for
- each language.
-
-`set check type on'
-`set check type off'
- Set type checking on or off, overriding the default setting for the
- current working language. Issue a warning if the setting does not
- match the language default. If any type mismatches occur in
- evaluating an expression while typechecking is on, GDB prints a
- message and aborts evaluation of the expression.
-
-`set check type warn'
- Cause the type checker to issue warnings, but to always attempt to
- evaluate the expression. Evaluating the expression may still be
- impossible for other reasons. For example, GDB cannot add numbers
- and structures.
-
-`show type'
- Show the current setting of the type checker, and whether or not
- GDB is setting it automatically.

-An overview of range checking
------------------------------
-
- In some languages (such as Modula-2), it is an error to exceed the
-bounds of a type; this is enforced with run-time checks. Such range
-checking is meant to ensure program correctness by making sure
-computations do not overflow, or indices on an array element access do
-not exceed the bounds of the array.
-
- For expressions you use in GDB commands, you can tell GDB to treat
-range errors in one of three ways: ignore them, always treat them as
-errors and abandon the expression, or issue warnings but evaluate the
-expression anyway.
-
- A range error can result from numerical overflow, from exceeding an
-array index bound, or when you type a constant that is not a member of
-any type. Some languages, however, do not treat overflows as an error.
-In many implementations of C, mathematical overflow causes the result
-to "wrap around" to lower values--for example, if M is the largest
-integer value, and S is the smallest, then
-
- M + 1 => S
-
- This, too, is specific to individual languages, and in some cases
-specific to individual compilers or machines. *Note Supported
-languages: Support, for further details on specific languages.
-
- GDB provides some additional commands for controlling the range
-checker:
-
-`set check range auto'
- Set range checking on or off based on the current working language.
- *Note Supported languages: Support, for the default settings for
- each language.
-
-`set check range on'
-`set check range off'
- Set range checking on or off, overriding the default setting for
- the current working language. A warning is issued if the setting
- does not match the language default. If a range error occurs,
- then a message is printed and evaluation of the expression is
- aborted.
-
-`set check range warn'
- Output messages when the GDB range checker detects a range error,
- but attempt to evaluate the expression anyway. Evaluating the
- expression may still be impossible for other reasons, such as
- accessing memory that the process does not own (a typical example
- from many Unix systems).
-
-`show range'
- Show the current setting of the range checker, and whether or not
- it is being set automatically by GDB.

-Supported languages
-===================
-
- GDB 4 supports C, C++, and Modula-2. Some GDB features may be used
-in expressions regardless of the language you use: the GDB `@' and `::'
-operators, and the `{type}addr' construct (*note Expressions:
-Expressions.) can be used with the constructs of any supported language.
-
- The following sections detail to what degree each source language is
-supported by GDB. These sections are not meant to be language
-tutorials or references, but serve only as a reference guide to what the
-GDB expression parser will accept, and what input and output formats
-should look like for different languages. There are many good books
-written on each of these languages; please look to these for a language
-reference or tutorial.

-C and C++
----------
-
- Since C and C++ are so closely related, many features of GDB apply
-to both languages. Whenever this is the case, we discuss both languages
-together.
-
- The C++ debugging facilities are jointly implemented by the GNU C++
-compiler and GDB. Therefore, to debug your C++ code effectively, you
-must compile your C++ programs with the GNU C++ compiler, `g++'.

-C and C++ operators
--------------------
-
- Operators must be defined on values of specific types. For instance,
-`+' is defined on numbers, but not on structures. Operators are often
-defined on groups of types.
-
- For the purposes of C and C++, the following definitions hold:
-
- * *Integral types* include `int' with any of its storage-class
- specifiers; `char'; and `enum'.
-
- * *Floating-point types* include `float' and `double'.
-
- * *Pointer types* include all types defined as `(TYPE *)'.
-
- * *Scalar types* include all of the above.
-
-The following operators are supported. They are listed here in order
-of increasing precedence:
-
-`,'
- The comma or sequencing operator. Expressions in a
- comma-separated list are evaluated from left to right, with the
- result of the entire expression being the last expression
- evaluated.
-
-`='
- Assignment. The value of an assignment expression is the value
- assigned. Defined on scalar types.
-
-`OP='
- Used in an expression of the form `A OP= B', and translated to
- `A = A OP B'. `OP=' and `=' have the same precendence. OP is any
- one of the operators `|', `^', `&', `<<', `>>', `+', `-', `*',
- `/', `%'.
-
-`?:'
- The ternary operator. `A ? B : C' can be thought of as: if A
- then B else C. A should be of an integral type.
-
-`||'
- Logical OR. Defined on integral types.
-
-`&&'
- Logical AND. Defined on integral types.
-
-`|'
- Bitwise OR. Defined on integral types.
-
-`^'
- Bitwise exclusive-OR. Defined on integral types.
-
-`&'
- Bitwise AND. Defined on integral types.
-
-`==, !='
- Equality and inequality. Defined on scalar types. The value of
- these expressions is 0 for false and non-zero for true.
-
-`<, >, <=, >='
- Less than, greater than, less than or equal, greater than or equal.
- Defined on scalar types. The value of these expressions is 0 for
- false and non-zero for true.
-
-`<<, >>'
- left shift, and right shift. Defined on integral types.
-
-`@'
- The GDB "artificial array" operator (*note Expressions:
- Expressions.).
-
-`+, -'
- Addition and subtraction. Defined on integral types,
- floating-point types and pointer types.
-
-`*, /, %'
- Multiplication, division, and modulus. Multiplication and
- division are defined on integral and floating-point types.
- Modulus is defined on integral types.
-
-`++, --'
- Increment and decrement. When appearing before a variable, the
- operation is performed before the variable is used in an
- expression; when appearing after it, the variable's value is used
- before the operation takes place.
-
-`*'
- Pointer dereferencing. Defined on pointer types. Same precedence
- as `++'.
-
-`&'
- Address operator. Defined on variables. Same precedence as `++'.
-
- For debugging C++, GDB implements a use of `&' beyond what is
- allowed in the C++ language itself: you can use `&(&REF)' (or, if
- you prefer, simply `&&REF') to examine the address where a C++
- reference variable (declared with `&REF') is stored.
-
-`-'
- Negative. Defined on integral and floating-point types. Same
- precedence as `++'.
-
-`!'
- Logical negation. Defined on integral types. Same precedence as
- `++'.
-
-`~'
- Bitwise complement operator. Defined on integral types. Same
- precedence as `++'.
-
-`., ->'
- Structure member, and pointer-to-structure member. For
- convenience, GDB regards the two as equivalent, choosing whether
- to dereference a pointer based on the stored type information.
- Defined on `struct' and `union' data.
-
-`[]'
- Array indexing. `A[I]' is defined as `*(A+I)'. Same precedence
- as `->'.
-
-`()'
- Function parameter list. Same precedence as `->'.
-
-`::'
- C++ scope resolution operator. Defined on `struct', `union', and
- `class' types.
-
-`::'
- Doubled colons also represent the GDB scope operator (*note
- Expressions: Expressions.). Same precedence as `::', above.

-
-C and C++ constants
--------------------
-
- GDB allows you to express the constants of C and C++ in the
-following ways:
-
- * Integer constants are a sequence of digits. Octal constants are
- specified by a leading `0' (ie. zero), and hexadecimal constants by
- a leading `0x' or `0X'. Constants may also end with a letter `l',
- specifying that the constant should be treated as a `long' value.
-
- * Floating point constants are a sequence of digits, followed by a
- decimal point, followed by a sequence of digits, and optionally
- followed by an exponent. An exponent is of the form:
- `e[[+]|-]NNN', where NNN is another sequence of digits. The `+'
- is optional for positive exponents.
-
- * Enumerated constants consist of enumerated identifiers, or their
- integral equivalents.
-
- * Character constants are a single character surrounded by single
- quotes (`''), or a number--the ordinal value of the corresponding
- character (usually its ASCII value). Within quotes, the single
- character may be represented by a letter or by "escape sequences",
- which are of the form `\NNN', where NNN is the octal representation
- of the character's ordinal value; or of the form `\X', where `X'
- is a predefined special character--for example, `\n' for newline.
-
- * String constants are a sequence of character constants surrounded
- by double quotes (`"').
-
- * Pointer constants are an integral value. You can also write
- pointers to constants using the C operator `&'.
-
- * Array constants are comma-separated lists surrounded by braces `{'
- and `}'; for example, `{1,2,3}' is a three-element array of
- integers, `{{1,2}, {3,4}, {5,6}}' is a three-by-two array, and
- `{&"hi", &"there", &"fred"}' is a three-element array of pointers.

-
-C++ expressions
----------------
-
- GDB expression handling has a number of extensions to interpret a
-significant subset of C++ expressions.
-
- *Warning:* Most of these extensions depend on the use of additional
- debugging information in the symbol table, and thus require a rich,
- extendable object code format. In particular, if your system uses
- a.out, MIPS ECOFF, RS/6000 XCOFF, or Sun ELF with stabs extensions
- to the symbol table, these facilities are all available. Where
- the object code format is standard COFF, on the other hand, most
- of the C++ support in GDB will *not* work, nor can it. For the
- standard SVr4 debugging format, DWARF in ELF, the standard is
- still evolving, so the C++ support in GDB is still fragile; when
- this debugging format stabilizes, however, C++ support will also
- be available on systems that use it.
-
- 1. Member function calls are allowed; you can use expressions like
-
- count = aml->GetOriginal(x, y)
-
- 2. While a member function is active (in the selected stack frame),
- your expressions have the same namespace available as the member
- function; that is, GDB allows implicit references to the class
- instance pointer `this' following the same rules as C++.
-
- 3. You can call overloaded functions; GDB will resolve the function
- call to the right definition, with one restriction--you must use
- arguments of the type required by the function that you want to
- call. GDB will not perform conversions requiring constructors or
- user-defined type operators.
-
- 4. GDB understands variables declared as C++ references; you can use
- them in expressions just as you do in C++ source--they are
- automatically dereferenced.
-
- In the parameter list shown when GDB displays a frame, the values
- of reference variables are not displayed (unlike other variables);
- this avoids clutter, since references are often used for large
- structures. The *address* of a reference variable is always
- shown, unless you have specified `set print address off'.
-
- 5. GDB supports the C++ name resolution operator `::'--your
- expressions can use it just as expressions in your program do.
- Since one scope may be defined in another, you can use `::'
- repeatedly if necessary, for example in an expression like
- `SCOPE1::SCOPE2::NAME'. GDB also allows resolving name scope by
- reference to source files, in both C and C++ debugging (*note
- Program variables: Variables.).
-

-
-C and C++ defaults
-------------------
-
- If you allow GDB to set type and range checking automatically, they
-both default to `off' whenever the working language changes to C or
-C++. This happens regardless of whether you, or GDB, selected the
-working language.
-
- If you allow GDB to set the language automatically, it sets the
-working language to C or C++ on entering code compiled from a source
-file whose name ends with `.c', `.C', or `.cc'. *Note Having GDB infer
-the source language: Automatically, for further details.
-
-
-File: gdb.info, Node: C Checks, Next: Debugging C, Prev: C Defaults, Up: C
-
-C and C++ type and range checks
--------------------------------
-
- By default, when GDB parses C or C++ expressions, type checking is
-not used. However, if you turn type checking on, GDB will consider two
-variables type equivalent if:
-
- * The two variables are structured and have the same structure,
- union, or enumerated tag.
-
- * Two two variables have the same type name, or types that have been
- declared equivalent through `typedef'.
-
- Range checking, if turned on, is done on mathematical operations.
-Array indices are not checked, since they are often used to index a
-pointer that is not itself an array.
-
-

-
-GDB and C
----------
-
- The `set print union' and `show print union' commands apply to the
-`union' type. When set to `on', any `union' that is inside a `struct'
-or `class' will also be printed. Otherwise, it will appear as `{...}'.
-
- The `@' operator aids in the debugging of dynamic arrays, formed
-with pointers and a memory allocation function. *Note Expressions:
-Expressions.

-GDB features for C++
---------------------
-
- Some GDB commands are particularly useful with C++, and some are
-designed specifically for use with C++. Here is a summary:
-
-`breakpoint menus'
- When you want a breakpoint in a function whose name is overloaded,
- GDB breakpoint menus help you specify which function definition
- you want. *Note Breakpoint menus: Breakpoint Menus.
-
-`rbreak REGEX'
- Setting breakpoints using regular expressions is helpful for
- setting breakpoints on overloaded functions that are not members
- of any special classes. *Note Setting breakpoints: Set Breaks.
-
-`catch EXCEPTIONS'
-`info catch'
- Debug C++ exception handling using these commands. *Note
- Breakpoints and exceptions: Exception Handling.
-
-`ptype TYPENAME'
- Print inheritance relationships as well as other information for
- type TYPENAME. *Note Examining the Symbol Table: Symbols.
-
-`set print demangle'
-`show print demangle'
-`set print asm-demangle'
-`show print asm-demangle'
- Control whether C++ symbols display in their source form, both when
- displaying code as C++ source and when displaying disassemblies.
- *Note Print settings: Print Settings.
-
-`set print object'
-`show print object'
- Choose whether to print derived (actual) or declared types of
- objects. *Note Print settings: Print Settings.
-
-`set print vtbl'
-`show print vtbl'
- Control the format for printing virtual function tables. *Note
- Print settings: Print Settings.
-
-`Overloaded symbol names'
- You can specify a particular definition of an overloaded symbol,
- using the same notation that is used to declare such symbols in
- C++: type `SYMBOL(TYPES)' rather than just SYMBOL. You can also
- use the GDB command-line word completion facilities to list the
- available choices, or to finish the type list for you. *Note
- Command completion: Completion, for details on how to do this.

----------
-
- Operators must be defined on values of specific types. For instance,
-`+' is defined on numbers, but not on structures. Operators are often
-defined on groups of types. For the purposes of Modula-2, the
-following definitions hold:
-
- * *Integral types* consist of `INTEGER', `CARDINAL', and their
- subranges.
-
- * *Character types* consist of `CHAR' and its subranges.
-
- * *Floating-point types* consist of `REAL'.
-
- * *Pointer types* consist of anything declared as `POINTER TO TYPE'.
-
- * *Scalar types* consist of all of the above.
-
- * *Set types* consist of `SET' and `BITSET' types.
-
- * *Boolean types* consist of `BOOLEAN'.
-
-The following operators are supported, and appear in order of

-Built-in functions and procedures
----------------------------------
-
- Modula-2 also makes available several built-in procedures and
-functions. In describing these, the following metavariables are used:
-
-A
- represents an `ARRAY' variable.
-
-C
- represents a `CHAR' constant or variable.
-
-I
- represents a variable or constant of integral type.
-
-M
- represents an identifier that belongs to a set. Generally used in
- the same function with the metavariable S. The type of S should
- be `SET OF MTYPE' (where MTYPE is the type of M).
-
-N
- represents a variable or constant of integral or floating-point
- type.
-
-R
- represents a variable or constant of floating-point type.
-
-T
- represents a type.
-
-V
- represents a variable.
-
-X
- represents a variable or constant of one of many types. See the
- explanation of the function for details.
-
- All Modula-2 built-in procedures also return a result, described
-below.
-
-`ABS(N)'
- Returns the absolute value of N.
-
-`CAP(C)'
- If C is a lower case letter, it returns its upper case equivalent,
- otherwise it returns its argument
-
-`CHR(I)'
- Returns the character whose ordinal value is I.
-
-`DEC(V)'
- Decrements the value in the variable V. Returns the new value.
-
-`DEC(V,I)'
- Decrements the value in the variable V by I. Returns the new
- value.
-
-`EXCL(M,S)'
- Removes the element M from the set S. Returns the new set.
-
-`FLOAT(I)'
- Returns the floating point equivalent of the integer I.
-
-`HIGH(A)'
- Returns the index of the last member of A.
-
-`INC(V)'
- Increments the value in the variable V. Returns the new value.
-
-`INC(V,I)'
- Increments the value in the variable V by I. Returns the new
- value.
-
-`INCL(M,S)'
- Adds the element M to the set S if it is not already there.
- Returns the new set.
-
-`MAX(T)'
- Returns the maximum value of the type T.
-
-`MIN(T)'
- Returns the minimum value of the type T.
-
-`ODD(I)'
- Returns boolean TRUE if I is an odd number.
-
-`ORD(X)'
- Returns the ordinal value of its argument. For example, the
- ordinal value of a character is its ASCII value (on machines
- supporting the ASCII character set). X must be of an ordered
- type, which include integral, character and enumerated types.
-
-`SIZE(X)'
- Returns the size of its argument. X can be a variable or a type.
-
-`TRUNC(R)'
- Returns the integral part of R.
-
-`VAL(T,I)'
- Returns the member of the type T whose ordinal value is I.
-
- *Warning:* Sets and their operations are not yet supported, so
- GDB will treat the use of procedures `INCL' and `EXCL' as an error.

-
-Constants
----------
-
- GDB allows you to express the constants of Modula-2 in the following
-ways:
-
- * Integer constants are simply a sequence of digits. When used in an
- expression, a constant is interpreted to be type-compatible with
- the rest of the expression. Hexadecimal integers are specified by
- a trailing `H', and octal integers by a trailing `B'.
-
- * Floating point constants appear as a sequence of digits, followed
- by a decimal point and another sequence of digits. An optional
- exponent can then be specified, in the form `E[+|-]NNN', where
- `[+|-]NNN' is the desired exponent. All of the digits of the
- floating point constant must be valid decimal (base 10) digits.
-
- * Character constants consist of a single character enclosed by a
- pair of like quotes, either single (`'') or double (`"'). They may
- also be expressed by their ordinal value (their ASCII value,
- usually) followed by a `C'.
-
- * String constants consist of a sequence of characters enclosed by a
- pair of like quotes, either single (`'') or double (`"'). Escape
- sequences in the style of C are also allowed. *Note C and C++
- constants: C Constants, for a brief explanation of escape
- sequences.
-
- * Enumerated constants consist of an enumerated identifier.
-
- * Boolean constants consist of the identifiers `TRUE' and `FALSE'.
-
- * Pointer constants consist of integral values only.
-
- * Set constants are not yet supported.

-Modula-2 defaults
------------------
-
- If type and range checking are set automatically by GDB, they both
-default to `on' whenever the working language changes to Modula-2.
-This happens regardless of whether you, or GDB, selected the working
-language.
-
- If you allow GDB to set the language automatically, then entering
-code compiled from a file whose name ends with `.mod' will set the
-working language to Modula-2. *Note Having GDB set the language
-automatically: Automatically, for further details.
-
-
-File: gdb.info, Node: Deviations, Next: M2 Checks, Prev: M2 Defaults, Up: Modula-2
-
-Deviations from standard Modula-2
----------------------------------
-
- A few changes have been made to make Modula-2 programs easier to
-debug. This is done primarily via loosening its type strictness:
-
- * Unlike in standard Modula-2, pointer constants can be formed by
- integers. This allows you to modify pointer variables during
- debugging. (In standard Modula-2, the actual address contained in
- a pointer variable is hidden from you; it can only be modified
- through direct assignment to another pointer variable or
- expression that returned a pointer.)
-
- * C escape sequences can be used in strings and characters to
- represent non-printable characters. GDB will print out strings
- with these escape sequences embedded. Single non-printable
- characters are printed using the `CHR(NNN)' format.
-
- * The assignment operator (`:=') returns the value of its right-hand
- argument.
-
- * All built-in procedures both modify *and* return their argument.
-
-

-
-Modula-2 type and range checks
-------------------------------
-
- *Warning:* in this release, GDB does not yet perform type or range
- checking.
-
- GDB considers two Modula-2 variables type equivalent if:
-
- * They are of types that have been declared equivalent via a `TYPE
- T1 = T2' statement
-
- * They have been declared on the same line. (Note: This is true of
- the GNU Modula-2 compiler, but it may not be true of other
- compilers.)
-
- As long as type checking is enabled, any attempt to combine variables
-whose types are not equivalent is an error.
-
- Range checking is done on all mathematical operations, assignment,
-array index bounds, and all built-in functions and procedures.

-The scope operators `::' and `.'
---------------------------------
-
- There are a few subtle differences between the Modula-2 scope
-operator (`.') and the GDB scope operator (`::'). The two have similar
-syntax:
-
-

-GDB and Modula-2
-----------------
-
- Some GDB commands have little use when debugging Modula-2 programs.
-Five subcommands of `set print' and `show print' apply specifically to
-C and C++: `vtbl', `demangle', `asm-demangle', `object', and `union'.
-The first four apply to C++, and the last to the C `union' type, which
-has no direct analogue in Modula-2.
-
- The `@' operator (*note Expressions: Expressions.), while available
-while using any language, is not useful with Modula-2. Its intent is
-to aid the debugging of "dynamic arrays", which cannot be created in
-Modula-2 as they can in C or C++. However, because an address can be
-specified by an integral constant, the construct `{TYPE}ADREXP' is
-still useful. (*note Expressions: Expressions.)
-
- In GDB scripts, the Modula-2 inequality operator `#' is interpreted
-as the beginning of a comment. Use `<>' instead.

-
-Examining the Symbol Table
-**************************
-
- The commands described in this section allow you to inquire about the
-symbols (names of variables, functions and types) defined in your
-program. This information is inherent in the text of your program and
-does not change as your program executes. GDB finds it in your
-program's symbol table, in the file indicated when you started GDB
-(*note Choosing files: File Options.), or by one of the file-management
-commands (*note Commands to specify files: Files.).
-
- Occasionally, you may need to refer to symbols that contain unusual
-characters, which GDB ordinarily treats as word delimiters. The most
-frequent case is in referring to static variables in other source files
-(*note Program variables: Variables.). File names are recorded in
-object files as debugging symbols, but GDB would ordinarily parse a
-typical file name, like `foo.c', as the three words `foo' `.' `c'. To
-allow GDB to recognize `foo.c' as a single symbol, enclose it in single
-quotes; for example,
-
- p 'foo.c'::x
-
-looks up the value of `x' in the scope of the file `foo.c'.
-
-`info address SYMBOL'
- Describe where the data for SYMBOL is stored. For a register
- variable, this says which register it is kept in. For a
- non-register local variable, this prints the stack-frame offset at
- which the variable is always stored.
-
- Note the contrast with `print &SYMBOL', which does not work at all
- for a register variable, and for a stack local variable prints the
- exact address of the current instantiation of the variable.
-
-`whatis EXP'
- Print the data type of expression EXP. EXP is not actually
- evaluated, and any side-effecting operations (such as assignments
- or function calls) inside it do not take place. *Note
- Expressions: Expressions.
-
-`whatis'
- Print the data type of `$', the last value in the value history.
-
-`ptype TYPENAME'
- Print a description of data type TYPENAME. TYPENAME may be the
- name of a type, or for C code it may have the form `class
- CLASS-NAME', `struct STRUCT-TAG', `union UNION-TAG' or `enum
- ENUM-TAG'.
-
-`ptype EXP'
-`ptype'
- Print a description of the type of expression EXP. `ptype'
- differs from `whatis' by printing a detailed description, instead
- of just the name of the type.
-
- For example, for this variable declaration:
-
- struct complex {double real; double imag;} v;
-
- the two commands give this output:
-
- (gdb) whatis v
- type = struct complex
- (gdb) ptype v
- type = struct complex {
- double real;
- double imag;
- }
-
- As with `whatis', using `ptype' without an argument refers to the
- type of `$', the last value in the value history.
-
-`info types REGEXP'
-`info types'
- Print a brief description of all types whose name matches REGEXP
- (or all types in your program, if you supply no argument). Each
- complete typename is matched as though it were a complete line;
- thus, `i type value' gives information on all types in your
- program whose name includes the string `value', but `i type
- ^value$' gives information only on types whose complete name is
- `value'.
-
- This command differs from `ptype' in two ways: first, like
- `whatis', it does not print a detailed description; second, it
- lists all source files where a type is defined.
-
-`info source'
- Show the name of the current source file--that is, the source file
- for the function containing the current point of execution--and
- the language it was written in.
-
-`info sources'
- Print the names of all source files in your program for which
- there is debugging information, organized into two lists: files
- whose symbols have already been read, and files whose symbols will
- be read when needed.
-
-`info functions'
- Print the names and data types of all defined functions.
-
-`info functions REGEXP'
- Print the names and data types of all defined functions whose
- names contain a match for regular expression REGEXP. Thus, `info
- fun step' finds all functions whose names include `step'; `info
- fun ^step' finds those whose names start with `step'.
-
-`info variables'
- Print the names and data types of all variables that are declared
- outside of functions (i.e., excluding local variables).
-
-`info variables REGEXP'
- Print the names and data types of all variables (except for local
- variables) whose names contain a match for regular expression
- REGEXP.
-
-`maint print symbols FILENAME'
-`maint print psymbols FILENAME'
-`maint print msymbols FILENAME'
- Write a dump of debugging symbol data into the file FILENAME.
- These commands are used to debug the GDB symbol-reading code. Only
- symbols with debugging data are included. If you use `maint print
- symbols', GDB includes all the symbols for which it has already
- collected full details: that is, FILENAME reflects symbols for
- only those files whose symbols GDB has read. You can use the
- command `info sources' to find out which files these are. If you
- use `maint print psymbols' instead, the dump shows information
- about symbols that GDB only knows partially--that is, symbols
- defined in files that GDB has skimmed, but not yet read
- completely. Finally, `maint print msymbols' dumps just the
- minimal symbol information required for each object file from
- which GDB has read some symbols. *Note Commands to specify files:
- Files, for a discussion of how GDB reads symbols (in the
- description of `symbol-file').

-Altering Execution
-******************
-
- Once you think you have found an error in your program, you might
-want to find out for certain whether correcting the apparent error
-would lead to correct results in the rest of the run. You can find the
-answer by experiment, using the GDB features for altering execution of
-the program.
-
- For example, you can store new values into variables or memory
-locations, give your program a signal, restart it at a different
-address, or even return prematurely from a function to its caller.
-
-* Menu:
-
-* Assignment:: Assignment to variables
-* Jumping:: Continuing at a different address
-
-* Signaling:: Giving your program a signal
-
-* Returning:: Returning from a function
-* Calling:: Calling your program's functions
-* Patching:: Patching your program
-
-
-File: gdb.info, Node: Assignment, Next: Jumping, Up: Altering
-
-Assignment to variables
-=======================
-
- To alter the value of a variable, evaluate an assignment expression.
-*Note Expressions: Expressions. For example,
-
- print x=4
-
-stores the value 4 into the variable `x', and then prints the value of
-the assignment expression (which is 4). *Note Using GDB with Different
-Languages: Languages, for more information on operators in supported
-languages.
-
- If you are not interested in seeing the value of the assignment, use
-the `set' command instead of the `print' command. `set' is really the
-same as `print' except that the expression's value is not printed and
-is not put in the value history (*note Value history: Value History.).
-The expression is evaluated only for its effects.
-
- If the beginning of the argument string of the `set' command appears
-identical to a `set' subcommand, use the `set variable' command instead
-of just `set'. This command is identical to `set' except for its lack
-of subcommands. For example, if your program has a variable `width',
-you get an error if you try to set a new value with just `set width=13',
-because GDB has the command `set width':
-
- (gdb) whatis width
- type = double
- (gdb) p width
- $4 = 13
- (gdb) set width=47
- Invalid syntax in expression.
-
-The invalid expression, of course, is `=47'. In order to actually set
-the program's variable `width', use
-
- (gdb) set var width=47
-
- GDB allows more implicit conversions in assignments than C; you can
-freely store an integer value into a pointer variable or vice versa,
-and you can convert any structure to any other structure that is the
-same length or shorter.
-
- To store values into arbitrary places in memory, use the `{...}'
-construct to generate a value of specified type at a specified address
-(*note Expressions: Expressions.). For example, `{int}0x83040' refers
-to memory location `0x83040' as an integer (which implies a certain size
-and representation in memory), and
-
- set {int}0x83040 = 4
-
-stores the value 4 into that memory location.
-
-
-File: gdb.info, Node: Jumping, Next: Signaling, Prev: Assignment, Up: Altering
-
-Continuing at a different address
-=================================
-
- Ordinarily, when you continue your program, you do so at the place
-where it stopped, with the `continue' command. You can instead
-continue at an address of your own choosing, with the following
-commands:
-
-`jump LINESPEC'
- Resume execution at line LINESPEC. Execution will stop
- immediately if there is a breakpoint there. *Note Printing source
- lines: List, for a description of the different forms of LINESPEC.
-
- The `jump' command does not change the current stack frame, or the
- stack pointer, or the contents of any memory location or any
- register other than the program counter. If line LINESPEC is in a
- different function from the one currently executing, the results
- may be bizarre if the two functions expect different patterns of
- arguments or of local variables. For this reason, the `jump'
- command requests confirmation if the specified line is not in the
- function currently executing. However, even bizarre results are
- predictable if you are well acquainted with the machine-language
- code of your program.
-
-`jump *ADDRESS'
- Resume execution at the instruction at address ADDRESS.
-
- You can get much the same effect as the `jump' command by storing a
-new value into the register `$pc'. The difference is that this does
-not start your program running; it only changes the address where it
-*will* run when it is continued. For example,
-
- set $pc = 0x485
-
-causes the next `continue' command or stepping command to execute at
-address `0x485', rather than at the address where your program stopped.
-*Note Continuing and stepping: Continuing and Stepping.
-
- The most common occasion to use the `jump' command is to back up,
-perhaps with more breakpoints set, over a portion of a program that has
-already executed, in order to examine its execution in more detail.
-
-
-File: gdb.info, Node: Signaling, Next: Returning, Prev: Jumping, Up: Altering
-
-Giving your program a signal
-============================
-
-`signal SIGNAL'
- Resume execution where your program stopped, but immediately give
- it the signal SIGNAL. SIGNAL can be the name or the number of a
- signal. For example, on many systems `signal 2' and `signal
- SIGINT' are both ways of sending an interrupt signal.
-
- Alternatively, if SIGNAL is zero, continue execution without
- giving a signal. This is useful when your program stopped on
- account of a signal and would ordinary see the signal when resumed
- with the `continue' command; `signal 0' causes it to resume
- without a signal.
-
- `signal' does not repeat when you press RET a second time after
- executing the command.
-
- Invoking the `signal' command is not the same as invoking the `kill'
-utility from the shell. Sending a signal with `kill' causes GDB to
-decide what to do with the signal depending on the signal handling
-tables (*note Signals::.). The `signal' command passes the signal
-directly to your program.
-
-
-File: gdb.info, Node: Returning, Next: Calling, Prev: Signaling, Up: Altering
-
-Returning from a function
-=========================
-
-`return'
-`return EXPRESSION'
- You can cancel execution of a function call with the `return'
- command. If you give an EXPRESSION argument, its value is used as
- the function's return value.
-
- When you use `return', GDB discards the selected stack frame (and
-all frames within it). You can think of this as making the discarded
-frame return prematurely. If you wish to specify a value to be
-returned, give that value as the argument to `return'.
-
- This pops the selected stack frame (*note Selecting a frame:
-Selection.), and any other frames inside of it, leaving its caller as
-the innermost remaining frame. That frame becomes selected. The
-specified value is stored in the registers used for returning values of
-functions.
-
- The `return' command does not resume execution; it leaves the
-program stopped in the state that would exist if the function had just
-returned. In contrast, the `finish' command (*note Continuing and
-stepping: Continuing and Stepping.) resumes execution until the
-selected stack frame returns naturally.
-
-
-File: gdb.info, Node: Calling, Next: Patching, Prev: Returning, Up: Altering
-
-Calling program functions
-=========================
-
-`call EXPR'
- Evaluate the expression EXPR without displaying `void' returned
- values.
-
- You can use this variant of the `print' command if you want to
-execute a function from your program, but without cluttering the output
-with `void' returned values. The result is printed and saved in the
-value history, if it is not void.
-
-
-File: gdb.info, Node: Patching, Prev: Calling, Up: Altering
-
-Patching programs
-=================
-
- By default, GDB opens the file containing your program's executable
-code (or the corefile) read-only. This prevents accidental alterations
-to machine code; but it also prevents you from intentionally patching
-your program's binary.
-
- If you'd like to be able to patch the binary, you can specify that
-explicitly with the `set write' command. For example, you might want
-to turn on internal debugging flags, or even to make emergency repairs.
-
-`set write on'
-`set write off'
- If you specify `set write on', GDB will open executable and core
- files for both reading and writing; if you specify `set write off'
- (the default), GDB will open them read-only.
-
- If you have already loaded a file, you must load it again (using
- the `exec-file' or `core-file' command) after changing `set
- write', for your new setting to take effect.
-
-`show write'
- Display whether executable files and core files will be opened for
- writing as well as reading.

-GDB Files
-*********
-
- GDB needs to know the file name of the program to be debugged, both
-in order to read its symbol table and in order to start your program.
-To debug a core dump of a previous run, you must also tell GDB the name
-of the core dump file.
-
-* Menu:
-
-* Files:: Commands to specify files
-* Symbol Errors:: Errors reading symbol files
-
-
-File: gdb.info, Node: Files, Next: Symbol Errors, Up: GDB Files
-
-Commands to specify files
-=========================
-
- The usual way to specify executable and core dump file names is with
-the command arguments given when you start GDB (*note Getting In and
-Out of GDB: Invocation..
-
- Occasionally it is necessary to change to a different file during a
-GDB session. Or you may run GDB and forget to specify a file you want
-to use. In these situations the GDB commands to specify new files are
-useful.
-
-`file FILENAME'
- Use FILENAME as the program to be debugged. It is read for its
- symbols and for the contents of pure memory. It is also the
- program executed when you use the `run' command. If you do not
- specify a directory and the file is not found in the GDB working
- directory, GDB uses the environment variable `PATH' as a list of
- directories to search, just as the shell does when looking for a
- program to run. You can change the value of this variable, for
- both GDB and your program, using the `path' command.
-
- On systems with memory-mapped files, an auxiliary symbol table file
- `FILENAME.syms' may be available for FILENAME. If it is, GDB will
- map in the symbol table from `FILENAME.syms', starting up more
- quickly. See the descriptions of the options `-mapped' and
- `-readnow' (available on the command line, and with the commands
- `file', `symbol-file', or `add-symbol-file'), for more information.
-
-`file'
- `file' with no argument makes GDB discard any information it has
- on both executable file and the symbol table.
-
-`exec-file [ FILENAME ]'
- Specify that the program to be run (but not the symbol table) is
- found in FILENAME. GDB will search the environment variable `PATH'
- if necessary to locate your program. Omitting FILENAME means to
- discard information on the executable file.
-
-`symbol-file [ FILENAME ]'
- Read symbol table information from file FILENAME. `PATH' is
- searched when necessary. Use the `file' command to get both symbol
- table and program to run from the same file.
-
- `symbol-file' with no argument clears out GDB information on your
- program's symbol table.
-
- The `symbol-file' command causes GDB to forget the contents of its
- convenience variables, the value history, and all breakpoints and
- auto-display expressions. This is because they may contain
- pointers to the internal data recording symbols and data types,
- which are part of the old symbol table data being discarded inside
- GDB.
-
- `symbol-file' will not repeat if you press RET again after
- executing it once.
-
- When GDB is configured for a particular environment, it will
- understand debugging information in whatever format is the standard
- generated for that environment; you may use either a GNU compiler,
- or other compilers that adhere to the local conventions. Best
- results are usually obtained from GNU compilers; for example,
- using `gcc' you can generate debugging information for optimized
- code.
-
- On some kinds of object files, the `symbol-file' command does not
- normally read the symbol table in full right away. Instead, it
- scans the symbol table quickly to find which source files and
- which symbols are present. The details are read later, one source
- file at a time, as they are needed.
-
- The purpose of this two-stage reading strategy is to make GDB
- start up faster. For the most part, it is invisible except for
- occasional pauses while the symbol table details for a particular
- source file are being read. (The `set verbose' command can turn
- these pauses into messages if desired. *Note Optional warnings
- and messages: Messages/Warnings.)
-
- We have not implemented the two-stage strategy for COFF yet. When
- the symbol table is stored in COFF format, `symbol-file' reads the
- symbol table data in full right away.
-
-`symbol-file FILENAME [ -readnow ] [ -mapped ]'
-`file FILENAME [ -readnow ] [ -mapped ]'
- You can override the GDB two-stage strategy for reading symbol
- tables by using the `-readnow' option with any of the commands that
- load symbol table information, if you want to be sure GDB has the
- entire symbol table available.
-
- If memory-mapped files are available on your system through the
- `mmap' system call, you can use another option, `-mapped', to
- cause GDB to write the symbols for your program into a reusable
- file. Future GDB debugging sessions will map in symbol information
- from this auxiliary symbol file (if the program has not changed),
- rather than spending time reading the symbol table from the
- executable program. Using the `-mapped' option has the same
- effect as starting GDB with the `-mapped' command-line option.
-
- You can use both options together, to make sure the auxiliary
- symbol file has all the symbol information for your program.
-
- The auxiliary symbol file for a program called MYPROG is called
- `MYPROG.syms'. Once this file exists (so long as it is newer than
- the corresponding executable), GDB will always attempt to use it
- when you debug MYPROG; no special options or commands are needed.
-
- The `.syms' file is specific to the host machine where you run
- GDB. It holds an exact image of the internal GDB symbol table.
- It cannot be shared across multiple host platforms.
-
-`core-file [ FILENAME ]'
- Specify the whereabouts of a core dump file to be used as the
- "contents of memory". Traditionally, core files contain only some
- parts of the address space of the process that generated them; GDB
- can access the executable file itself for other parts.
-
- `core-file' with no argument specifies that no core file is to be
- used.
-
- Note that the core file is ignored when your program is actually
- running under GDB. So, if you have been running your program and
- you wish to debug a core file instead, you must kill the
- subprocess in which the program is running. To do this, use the
- `kill' command (*note Killing the child process: Kill Process.).
-
-`load FILENAME'
- Depending on what remote debugging facilities are configured into
- GDB, the `load' command may be available. Where it exists, it is
- meant to make FILENAME (an executable) available for debugging on
- the remote system--by downloading, or dynamic linking, for example.
- `load' also records the FILENAME symbol table in GDB, like the
- `add-symbol-file' command.
-
- If your GDB does not have a `load' command, attempting to execute
- it gets the error message "`You can't do that when your target is
- ...'"
-
- The file is loaded at whatever address is specified in the
- executable. For some object file formats, like a.out, the object
- file format fixes the address and so it won't necessarily match
- the address you gave to the linker.
-
- On VxWorks, `load' will dynamically link FILENAME on the current
- target system as well as adding its symbols in GDB.
-
- With the Nindy interface to an Intel 960 board, `load' will
- download FILENAME to the 960 as well as adding its symbols in GDB.
-
- When you select remote debugging to a Hitachi SH, H8/300, or
- H8/500 board (*note GDB and Hitachi Microprocessors: Hitachi
- Remote.), the `load' command downloads your program to the Hitachi
- board and also opens it as the current executable target for GDB
- on your host (like the `file' command).
-
- `load' will not repeat if you press RET again after using it.
-
-`add-symbol-file FILENAME ADDRESS'
-`add-symbol-file FILENAME ADDRESS [ -readnow ] [ -mapped ]'
- The `add-symbol-file' command reads additional symbol table
- information from the file FILENAME. You would use this command
- when FILENAME has been dynamically loaded (by some other means)
- into the program that is running. ADDRESS should be the memory
- address at which the file has been loaded; GDB cannot figure this
- out for itself. You can specify ADDRESS as an expression.
-
- The symbol table of the file FILENAME is added to the symbol table
- originally read with the `symbol-file' command. You can use the
- `add-symbol-file' command any number of times; the new symbol data
- thus read keeps adding to the old. To discard all old symbol data
- instead, use the `symbol-file' command.
-
- `add-symbol-file' will not repeat if you press RET after using it.
-
- You can use the `-mapped' and `-readnow' options just as with the
- `symbol-file' command, to change how GDB manages the symbol table
- information for FILENAME.
-
-`info files'
-`info target'
- `info files' and `info target' are synonymous; both print the
- current target (*note Specifying a Debugging Target: Targets.),
- including the names of the executable and core dump files
- currently in use by GDB, and the files from which symbols were
- loaded. The command `help targets' lists all possible targets
- rather than current ones.
-
- All file-specifying commands allow both absolute and relative file
-names as arguments. GDB always converts the file name to an absolute
-path name and remembers it that way.
-
- GDB supports SunOS, SVR4, and IBM RS/6000 shared libraries. GDB
-automatically loads symbol definitions from shared libraries when you
-use the `run' command, or when you examine a core file. (Before you
-issue the `run' command, GDB will not understand references to a
-function in a shared library, however--unless you are debugging a core
-file).
-
-`info share'
-`info sharedlibrary'
- Print the names of the shared libraries which are currently loaded.
-
-`sharedlibrary REGEX'
-`share REGEX'
- This is an obsolescent command; you can use it to explicitly load
- shared object library symbols for files matching a Unix regular
- expression, but as with files loaded automatically, it will only
- load shared libraries required by your program for a core file or
- after typing `run'. If REGEX is omitted all shared libraries
- required by your program are loaded.

-
-Errors reading symbol files
-===========================
-
- While reading a symbol file, GDB will occasionally encounter
-problems, such as symbol types it does not recognize, or known bugs in
-compiler output. By default, GDB does not notify you of such problems,
-since they are relatively common and primarily of interest to people
-debugging compilers. If you are interested in seeing information about
-ill-constructed symbol tables, you can either ask GDB to print only one
-message about each such type of problem, no matter how many times the
-problem occurs; or you can ask GDB to print more messages, to see how
-many times the problems occur, with the `set complaints' command (*note
-Optional warnings and messages: Messages/Warnings.).
-
- The messages currently printed, and their meanings, include:
-
-`inner block not inside outer block in SYMBOL'
- The symbol information shows where symbol scopes begin and end

- This error indicates that an inner scope block is not fully
- contained in its outer scope blocks.
-
- GDB circumvents the problem by treating the inner block as if it

- function.
-
-`block at ADDRESS out of order'

-Specifying a Debugging Target
-*****************************
-
- A "target" is the execution environment occupied by your program.
-Often, GDB runs in the same host environment as your program; in that
-case, the debugging target is specified as a side effect when you use
-the `file' or `core' commands. When you need more flexibility--for
-example, running GDB on a physically separate host, or controlling a
-standalone system over a serial port or a realtime system over a TCP/IP
-connection--you can use the `target' command to specify one of the
-target types configured for GDB (*note Commands for managing targets:
-Target Commands.).

-
-* Active Targets:: Active targets
-* Target Commands:: Commands for managing targets
-* Remote:: Remote debugging
-
-
-File: gdb.info, Node: Active Targets, Next: Target Commands, Up: Targets
-
-Active targets
-==============
-
- There are three classes of targets: processes, core files, and
-executable files. GDB can work concurrently on up to three active
-targets, one in each class. This allows you to (for example) start a
-process and inspect its activity without abandoning your work on a core
-file.
-
- For example, if you execute `gdb a.out', then the executable file
-`a.out' is the only active target. If you designate a core file as
-well--presumably from a prior run that crashed and coredumped--then GDB
-has two active targets and will use them in tandem, looking first in
-the corefile target, then in the executable file, to satisfy requests
-for memory addresses. (Typically, these two classes of target are
-complementary, since core files contain only a program's read-write
-memory--variables and so on--plus machine status, while executable
-files contain only the program text and initialized data.)
-
- When you type `run', your executable file becomes an active process
-target as well. When a process target is active, all GDB commands
-requesting memory addresses refer to that target; addresses in an
-active core file or executable file target are obscured while the
-process target is active.
-
- Use the `core-file' and `exec-file' commands to select a new core
-file or executable target (*note Commands to specify files: Files.).
-To specify as a target a process that is already running, use the
-`attach' command (*note Debugging an already-running process: Attach.).

-
-Commands for managing targets
-=============================
-
-`target TYPE PARAMETERS'
- Connects the GDB host environment to a target machine or process.
- A target is typically a protocol for talking to debugging
- facilities. You use the argument TYPE to specify the type or
- protocol of the target machine.
-
- Further PARAMETERS are interpreted by the target protocol, but
- typically include things like device names or host names to connect
- with, process numbers, and baud rates.
-
- The `target' command will not repeat if you press RET again after
- executing the command.
-
-`help target'
- Displays the names of all targets available. To display targets
- currently selected, use either `info target' or `info files'
- (*note Commands to specify files: Files.).
-
-`help target NAME'
- Describe a particular target, including any parameters necessary to
- select it.
-
- Here are some common targets (available, or not, depending on the GDB
-configuration):
-
-`target exec PROGRAM'
- An executable file. `target exec PROGRAM' is the same as
- `exec-file PROGRAM'.
-
-`target core FILENAME'
- A core dump file. `target core FILENAME' is the same as
- `core-file FILENAME'.
-
-`target remote DEV'
- Remote serial target in GDB-specific protocol. The argument DEV
- specifies what serial device to use for the connection (e.g.
- `/dev/ttya'). *Note Remote debugging: Remote.
-
-`target sim'
- CPU simulator. *Note Simulated CPU Target: Simulator.
-
-`target udi KEYWORD'
- Remote AMD29K target, using the AMD UDI protocol. The KEYWORD
- argument specifies which 29K board or simulator to use. *Note GDB
- and the UDI protocol for AMD29K: UDI29K Remote.
-
-`target amd-eb DEV SPEED PROG'
- Remote PC-resident AMD EB29K board, attached over serial lines.
- dEV is the serial device, as for `target remote'; SPEED allows you
- to specify the linespeed; and PROG is the name of the program to
- be debugged, as it appears to DOS on the PC. *Note GDB with a
- remote EB29K: EB29K Remote.
-
-`target hms'
- A Hitachi SH, H8/300, or H8/500 board, attached via serial line to
- your host. Use special commands `device' and `speed' to control
- the serial line and the communications speed used. *Note GDB and
- Hitachi Microprocessors: Hitachi Remote.
-
-`target nindy DEVICENAME'
- An Intel 960 board controlled by a Nindy Monitor. DEVICENAME is
- the name of the serial device to use for the connection, e.g.
- `/dev/ttya'. *Note GDB with a remote i960 (Nindy): i960-Nindy
- Remote.
-
-`target st2000 DEV SPEED'
- A Tandem ST2000 phone switch, running Tandem's STDBUG protocol.
- dEV is the name of the device attached to the ST2000 serial line;
- SPEED is the communication line speed. The arguments are not used
- if GDB is configured to connect to the ST2000 using TCP or Telnet.
- *Note GDB with a Tandem ST2000: ST2000 Remote.
-
-`target vxworks MACHINENAME'
- A VxWorks system, attached via TCP/IP. The argument MACHINENAME
- is the target system's machine name or IP address. *Note GDB and
- VxWorks: VxWorks Remote.
-
- Different targets are available on different configurations of GDB;
-your configuration may have more or fewer targets.

-Remote debugging
-================
-
- If you are trying to debug a program running on a machine that
-cannot run GDB in the usual way, it is often useful to use remote
-debugging. For example, you might use remote debugging on an operating
-system kernel, or on a small system which does not have a general
-purpose operating system powerful enough to run a full-featured
-debugger.
-
- Some configurations of GDB have special serial or TCP/IP interfaces
-to make this work with particular debugging targets. In addition, GDB
-comes with a generic serial protocol (specific to GDB, but not specific
-to any particular target system) which you can use if you write the
-remote stubs--the code that will run on the remote system to
-communicate with GDB.
-
- Other remote targets may be available in your configuration of GDB;
-use `help targets' to list them.

-
-The GDB remote serial protocol
-------------------------------
-
- To debug a program running on another machine (the debugging
-"target" machine), you must first arrange for all the usual
-prerequisites for the program to run by itself. For example, for a C
-program, you need
-
- 1. A startup routine to set up the C runtime environment; these
- usually have a name like `crt0'. The startup routine may be
- supplied by your hardware supplier, or you may have to write your
- own.
-
- 2. You probably need a C subroutine library to support your program's
- subroutine calls, notably managing input and output.
-
- 3. A way of getting your program to the other machine--for example, a
- download program. These are often supplied by the hardware
- manufacturer, but you may have to write your own from hardware
- documentation.
-
- The next step is to arrange for your program to use a serial port to
-communicate with the machine where GDB is running (the "host" machine).
-In general terms, the scheme looks like this:
-
-*On the host,*
- GDB already understands how to use this protocol; when everything
- else is set up, you can simply use the `target remote' command
- (*note Specifying a Debugging Target: Targets.).
-
-*On the target,*
- you must link with your program a few special-purpose subroutines
- that implement the GDB remote serial protocol. The file
- containing these subroutines is called a "debugging stub".
-
- On certain remote targets, you can use an auxiliary program
- `gdbserver' instead of linking a stub into your program. *Note
- Using the `gdbserver' program: Server, for details.
-
- The debugging stub is specific to the architecture of the remote
-machine; for example, use `sparc-stub.c' to debug programs on SPARC
-boards.
-
- These working remote stubs are distributed with GDB:
-
-`sparc-stub.c'
- For SPARC architectures.
-
-`m68k-stub.c'
- For Motorola 680x0 architectures.
-
-`i386-stub.c'
- For Intel 386 and compatible architectures.
-
- The `README' file in the GDB distribution may list other recently
-added stubs.

-
-
-File: gdb.info, Node: Stub Contents, Next: Bootstrapping, Up: Remote Serial
-
-What the stub can do for you
-----------------------------
-
- The debugging stub for your architecture supplies these three
-subroutines:
-
-`set_debug_traps'
- This routine arranges for `handle_exception' to run when your
- program stops. You must call this subroutine explicitly near the
- beginning of your program.
-
-`handle_exception'
- This is the central workhorse, but your program never calls it
- explicitly--the setup code arranges for `handle_exception' to run
- when a trap is triggered.
-
- `handle_exception' takes control when your program stops during
- execution (for example, on a breakpoint), and mediates
- communications with GDB on the host machine. This is where the
- communications protocol is implemented; `handle_exception' acts as
- the GDB representative on the target machine; it begins by sending
- summary information on the state of your program, then continues
- to execute, retrieving and transmitting any information GDB needs,
- until you execute a GDB command that makes your program resume; at
- that point, `handle_exception' returns control to your own code on
- the target machine.
-
-`breakpoint'
- Use this auxiliary subroutine to make your program contain a
- breakpoint. Depending on the particular situation, this may be
- the only way for GDB to get control. For instance, if your target
- machine has some sort of interrupt button, you won't need to call
- this; pressing the interrupt button will transfer control to
- `handle_exception'--in effect, to GDB. On some machines, simply
- receiving characters on the serial port may also trigger a trap;
- again, in that situation, you don't need to call `breakpoint' from
- your own program--simply running `target remote' from the host GDB
- session will get control.
-
- Call `breakpoint' if none of these is true, or if you simply want
- to make certain your program stops at a predetermined point for the
- start of your debugging session.
-
-
-File: gdb.info, Node: Bootstrapping, Next: Debug Session, Prev: Stub Contents, Up: Remote Serial
-
-What you must do for the stub
------------------------------
-
- The debugging stubs that come with GDB are set up for a particular
-chip architecture, but they have no information about the rest of your
-debugging target machine. To allow the stub to work, you must supply
-these special low-level subroutines:
-
-`int getDebugChar()'
- Write this subroutine to read a single character from the serial
- port. It may be identical to `getchar' for your target system; a
- different name is used to allow you to distinguish the two if you
- wish.
-
-`void putDebugChar(int)'
- Write this subroutine to write a single character to the serial
- port. It may be identical to `putchar' for your target system; a
- different name is used to allow you to distinguish the two if you
- wish.
-
-`void exceptionHandler (int EXCEPTION_NUMBER, void *EXCEPTION_ADDRESS)'
- Write this function to install EXCEPTION_ADDRESS in the exception
- handling tables. You need to do this because the stub does not
- have any way of knowing what the exception handling tables on your
- target system are like (for example, the processor's table might
- be in ROM, containing entries which point to a table in RAM).
- eXCEPTION_NUMBER is the exception number which should be changed;
- its meaning is architecture-dependent (for example, different
- numbers might represent divide by zero, misaligned access, etc).
- When this exception occurs, control should be transferred directly
- to EXCEPTION_ADDRESS, and the processor state (stack, registers,
- etc.) should be just as it is when a processor exception occurs.
- So if you want to use a jump instruction to reach
- EXCEPTION_ADDRESS, it should be a simple jump, not a jump to
- subroutine.
-
- For the 386, EXCEPTION_ADDRESS should be installed as an interrupt
- gate so that interrupts are masked while the handler runs. The
- gate should be at privilege level 0 (the most privileged level).
- The SPARC and 68k stubs are able to mask interrupts themself
- without help from `exceptionHandler'.
-
-`void flush_i_cache()'
- Write this subroutine to flush the instruction cache, if any, on
- your target machine. If there is no instruction cache, this
- subroutine may be a no-op.
-
- On target machines that have instruction caches, GDB requires this
- function to make certain that the state of your program is stable.
-
-You must also make sure this library routine is available:
-
-`void *memset(void *, int, int)'
- This is the standard library function `memset' that sets an area of
- memory to a known value. If you have one of the free versions of
- `libc.a', `memset' can be found there; otherwise, you must either
- obtain it from your hardware manufacturer, or write your own.
-
- If you do not use the GNU C compiler, you may need other standard
-library subroutines as well; this will vary from one stub to another,
-but in general the stubs are likely to use any of the common library
-subroutines which `gcc' generates as inline code.
-
-
-File: gdb.info, Node: Debug Session, Next: Protocol, Prev: Bootstrapping, Up: Remote Serial
-
-Putting it all together
------------------------
-
- In summary, when your program is ready to debug, you must follow
-these steps.
-
- 1. Make sure you have the supporting low-level routines (*note What
- you must do for the stub: Bootstrapping.):
- `getDebugChar', `putDebugChar',
- `flush_i_cache', `memset', `exceptionHandler'.
-
- 2. Insert these lines near the top of your program:
-
- set_debug_traps();
- breakpoint();
-
- 3. For the 680x0 stub only, you need to provide a variable called
- `exceptionHook'. Normally you just use
-
- void (*exceptionHook)() = 0;
-
- but if before calling `set_debug_traps', you set it to point to a
- function in your program, that function is called when `GDB'
- continues after stopping on a trap (for example, bus error). The
- function indicated by `exceptionHook' is called with one
- parameter: an `int' which is the exception number.
-
- 4. Compile and link together: your program, the GDB debugging stub for
- your target architecture, and the supporting subroutines.
-
- 5. Make sure you have a serial connection between your target machine
- and the GDB host, and identify the serial port used for this on
- the host.
-
- 6. Download your program to your target machine (or get it there by
- whatever means the manufacturer provides), and start it.
-
- 7. To start remote debugging, run GDB on the host machine, and specify
- as an executable file the program that is running in the remote
- machine. This tells GDB how to find your program's symbols and
- the contents of its pure text.
-
- Then establish communication using the `target remote' command.
- Its argument specifies how to communicate with the target
- machine--either via a devicename attached to a direct serial line,
- or a TCP port (usually to a terminal server which in turn has a
- serial line to the target). For example, to use a serial line
- connected to the device named `/dev/ttyb':
-
- target remote /dev/ttyb
-
- To use a TCP connection, use an argument of the form `HOST:port'.
- For example, to connect to port 2828 on a terminal server named
- `manyfarms':
-
- target remote manyfarms:2828
-
- Now you can use all the usual commands to examine and change data
-and to step and continue the remote program.
-
- To resume the remote program and stop debugging it, use the `detach'
-command.
-
- Whenever GDB is waiting for the remote program, if you type the
-interrupt character (often C-C), GDB attempts to stop the program.
-This may or may not succeed, depending in part on the hardware and the
-serial drivers the remote system uses. If you type the interrupt
-character once again, GDB displays this prompt:
-
- Interrupted while waiting for the program.
- Give up (and stop debugging it)? (y or n)
-
- If you type `y', GDB abandons the remote debugging session. (If you
-decide you want to try again later, you can use `target remote' again
-to connect once more.) If you type `n', GDB goes back to waiting.
-
-
-File: gdb.info, Node: Protocol, Next: Server, Prev: Debug Session, Up: Remote Serial
-
-Outline of the communication protocol
--------------------------------------
-
- The stub files provided with GDB implement the target side of the
-communication protocol, and the GDB side is implemented in the GDB
-source file `remote.c'. Normally, you can simply allow these
-subroutines to communicate, and ignore the details. (If you're
-implementing your own stub file, you can still ignore the details: start
-with one of the existing stub files. `sparc-stub.c' is the best
-organized, and therefore the easiest to read.)
-
- However, there may be occasions when you need to know something about
-the protocol--for example, if there is only one serial port to your
-target machine, you might want your program to do something special if
-it recognizes a packet meant for GDB.
-
- All GDB commands and responses (other than acknowledgements, which
-are single characters) are sent as a packet which includes a checksum.
-A packet is introduced with the character `$', and ends with the
-character `#' followed by a two-digit checksum:
-
- $PACKET INFO#CHECKSUM
-
-CHECKSUM is computed as the modulo 256 sum of the PACKET INFO
-characters.
-
- When either the host or the target machine receives a packet, the
-first response expected is an acknowledgement: a single character,
-either `+' (to indicate the package was received correctly) or `-' (to
-request retransmission).
-
- The host (GDB) sends commands, and the target (the debugging stub
-incorporated in your program) sends data in response. The target also
-sends data when your program stops.
-
- Command packets are distinguished by their first character, which
-identifies the kind of command.
-
- These are the commands currently supported:
-
-`g'
- Requests the values of CPU registers.
-
-`G'
- Sets the values of CPU registers.
-
-`mADDR,COUNT'
- Read COUNT bytes at location ADDR.
-
-`MADDR,COUNT:...'
- Write COUNT bytes at location ADDR.
-
-`c'
-`cADDR'
- Resume execution at the current address (or at ADDR if supplied).
-
-`s'
-`sADDR'
- Step the target program for one instruction, from either the
- current program counter or from ADDR if supplied.
-
-`k'
- Kill the target program.
-
-`?'
- Report the most recent signal. To allow you to take advantage of
- the GDB signal handling commands, one of the functions of the
- debugging stub is to report CPU traps as the corresponding POSIX
- signal values.
-
- If you have trouble with the serial connection, you can use the
-command `set remotedebug'. This makes GDB report on all packets sent
-back and forth across the serial line to the remote machine. The
-packet-debugging information is printed on the GDB standard output
-stream. `set remotedebug off' turns it off, and `show remotedebug'
-will show you its current state.

-
-Using the `gdbserver' program
------------------------------
-
- `gdbserver' is a control program for Unix-like systems, which allows
-you to connect your program with a remote GDB via `target remote'--but
-without linking in the usual debugging stub.
-
- `gdbserver' is not a complete replacement for the debugging stubs,
-because it requires essentially the same operating-system facilities
-that GDB itself does. In fact, a system that can run `gdbserver' to
-connect to a remote GDB could also run GDBN locally! `gdbserver' is
-sometimes useful nevertheless, because it is a much smaller program
-than GDB itself. It is also easier to port than all of GDBN, so you
-may be able to get started more quickly on a new system by using
-`gdbserver'.
-
- GDB and `gdbserver' communicate via either a serial line or a TCP
-connection, using the standard GDB remote serial protocol.
-
-*On the target,*
- you need to have a copy of the program you want to debug.
- `gdbserver' does not need your program's symbol table, so you can
- strip the program if necessary to save space. GDB on the host
- system does all the symbol handling.
-
- To use the server, you must tell it how to communicate with {No
- Value For "GDB"}; the name of your program; and the arguments for
- your program. The syntax is:
-
- target> gdbserver COMM PROGRAM [ ARGS ... ]
-
- COMM is either a device name (to use a serial line) or a TCP
- hostname and portnumber. For example, to debug emacs with the
- argument `foo.txt' and communicate with GDB over the serial port
- `/dev/com1':
-
- target> gdbserver /dev/com1 emacs foo.txt
-
- `gdbserver' waits passively for the host GDB to communicate with
- it.
-
- To use a TCP connection instead of a serial line:
-
- target> gdbserver host:2345 emacs foo.txt
-
- The only difference from the previous example is the first
- argument, specifying that you are communicating with the host GDB
- via TCP. The `host:2345' argument means that `gdbserver' is to
- expect a TCP connection from machine `host' to local TCP port 2345.
- (Currently, the `host' part is ignored.) You can choose any number
- you want for the port number as long as it does not conflict with
- any TCP ports already in use on the target system.(1) You must use
- the same port number with the host GDB `target remote' command.
-
-*On the host,*
- you need an unstripped copy of your program, since GDB needs
- symbols and debugging information. Start up GDB as usual, using
- the name of the local copy of your program as the first argument.
- (You may also need the `--baud' option if the serial line is
- running at anything other than 9600 bps.) After that, use `target
- remote' to establish communications with `gdbserver'. Its
- argument is either a device name (usually a serial device, like
- `/dev/ttyb'), or a TCP port descriptof in the form `HOST:PORT'.
- For example:
-
- (gdb) target remote /dev/ttyb
-
- communicates with the server via serial line `/dev/ttyb', and
-
- (gdb) target remote the-target:2345
-
- communicates via a TCP connection to port 2345 on host
- `the-target'. For TCP connections, you must start up `gdbserver'
- prior to using the `target remote' command. Otherwise you may get
- an error whose text depends on the host system, but which usually
- looks something like `Connection refused'.
-
- ---------- Footnotes ----------
-
- (1) If you choose a port number that conflicts with another
-service, `gdbserver' prints an error message and exits.

- * Through command line options specifying serial port, version of the
- Nindy protocol, and communications speed;
-
- * By responding to a prompt on startup;

-------------------
-
- If you simply start `gdb' without using any command-line options,
-you are prompted for what serial port to use, *before* you reach the
-ordinary GDB prompt:
-
- Attach /dev/ttyNN -- specify NN, or "quit" to quit:
-
-Respond to the prompt with whatever suffix (after `/dev/tty')
-identifies the serial port you want to use. You can, if you choose,

-
-Options for Nindy
------------------
-
- These are the startup options for beginning your GDB session with a
-Nindy-960 board attached:
-
-`-r PORT'
- Specify the serial port name of a serial interface to be used to
- connect to the target system. This option is only available when
- GDB is configured for the Intel 960 target architecture. You may
- specify PORT as any of: a full pathname (e.g. `-r /dev/ttya'), a
- device name in `/dev' (e.g. `-r ttya'), or simply the unique
- suffix for a specific `tty' (e.g. `-r a').
-
-`-O'
- (An uppercase letter "O", not a zero.) Specify that GDB should use
- the "old" Nindy monitor protocol to connect to the target system.
- This option is only available when GDB is configured for the Intel
- 960 target architecture.
-
- *Warning:* if you specify `-O', but are actually trying to
- connect to a target system that expects the newer protocol,
- the connection fails, appearing to be a speed mismatch. GDB
- repeatedly attempts to reconnect at several different line
- speeds. You can abort this process with an interrupt.
-
-`-brk'
- Specify that GDB should first send a `BREAK' signal to the target
- system, in an attempt to reset it, before connecting to a Nindy
- target.
-
- *Warning:* Many target systems do not have the hardware that
- this requires; it only works with a few boards.
-
- The standard `-b' option controls the line speed used on the serial
-port.
-
-
-File: gdb.info, Node: Nindy Reset, Prev: Nindy Options, Up: i960-Nindy Remote
-
-Nindy reset command
--------------------
-
-`reset'
- For a Nindy target, this command sends a "break" to the remote
- target system; this is only useful if the target has been equipped
- with a circuit to perform a hard reset (or some other interesting
- action) when a break is detected.

-GDB and the UDI protocol for AMD29K
------------------------------------
-
- GDB supports AMD's UDI ("Universal Debugger Interface") protocol for
-debugging the a29k processor family. To use this configuration with
-AMD targets running the MiniMON monitor, you need the program `MONTIP',
-available from AMD at no charge. You can also use GDB with the UDI
-conformant a29k simulator program `ISSTIP', also available from AMD.
-
-`target udi KEYWORD'
- Select the UDI interface to a remote a29k board or simulator, where
- KEYWORD is an entry in the AMD configuration file `udi_soc'. This
- file contains keyword entries which specify parameters used to
- connect to a29k targets. If the `udi_soc' file is not in your
- working directory, you must set the environment variable `UDICONF'
- to its pathname.

-
-GDB and the EBMON protocol for AMD29K
--------------------------------------
-
- AMD distributes a 29K development board meant to fit in a PC,
-together with a DOS-hosted monitor program called `EBMON'. As a
-shorthand term, this development system is called the "EB29K". To use
-GDB from a Unix system to run programs on the EB29K board, you must
-first connect a serial cable between the PC (which hosts the EB29K
-board) and a serial port on the Unix system. In the following, we
-assume you've hooked the cable between the PC's `COM1' port and
-`/dev/ttya' on the Unix system.

-
-Communications setup
---------------------
-
- The next step is to set up the PC's port, by doing something like
-this in DOS on the PC:
-
- C:\> MODE com1:9600,n,8,1,none
-
-This example--run on an MS DOS 4.0 system--sets the PC port to 9600
-bps, no parity, eight data bits, one stop bit, and no "retry" action;
-you must match the communications parameters when establishing the Unix
-end of the connection as well.
-
- To give control of the PC to the Unix side of the serial line, type
-the following at the DOS console:
-
- C:\> CTTY com1
-
-(Later, if you wish to return control to the DOS console, you can use
-the command `CTTY con'--but you must send it over the device that had
-control, in our example over the `COM1' serial line).
-
- From the Unix host, use a communications program such as `tip' or
-`cu' to communicate with the PC; for example,
-
- cu -s 9600 -l /dev/ttya
-
-The `cu' options shown specify, respectively, the linespeed and the
-serial port to use. If you use `tip' instead, your command line may
-look something like the following:
-
- tip -9600 /dev/ttya
-
-Your system may require a different name where we show `/dev/ttya' as
-the argument to `tip'. The communications parameters, including which
-port to use, are associated with the `tip' argument in the "remote"
-descriptions file--normally the system table `/etc/remote'.
-
- Using the `tip' or `cu' connection, change the DOS working directory
-to the directory containing a copy of your 29K program, then start the
-PC program `EBMON' (an EB29K control program supplied with your board
-by AMD). You should see an initial display from `EBMON' similar to the
-one that follows, ending with the `EBMON' prompt `#'--
-

-
- Then exit the `cu' or `tip' program (done in the example by typing
-`~.' at the `EBMON' prompt). `EBMON' will keep running, ready for GDB
-to take over.
-
- For this example, we've assumed what is probably the most convenient
-way to make sure the same 29K program is on both the PC and the Unix
-system: a PC/NFS connection that establishes "drive `G:'" on the PC as
-a file system on the Unix host. If you do not have PC/NFS or something
-similar connecting the two systems, you must arrange some other
-way--perhaps floppy-disk transfer--of getting the 29K program from the
-Unix system to the PC; GDB will *not* download it over the serial line.

-
-EB29K cross-debugging
----------------------
-
- Finally, `cd' to the directory containing an image of your 29K
-program on the Unix system, and start GDB--specifying as argument the
-name of your 29K program:
-
- cd /usr/joe/work29k
- gdb myfoo
-
- Now you can use the `target' command:
-
- target amd-eb /dev/ttya 9600 MYFOO
-
-In this example, we've assumed your program is in a file called
-`myfoo'. Note that the filename given as the last argument to `target
-amd-eb' should be the name of the program as it appears to DOS. In our
-example this is simply `MYFOO', but in general it can include a DOS
-path, and depending on your transfer mechanism may not resemble the
-name on the Unix side.
-
- At this point, you can set any breakpoints you wish; when you are
-ready to see your program run on the 29K board, use the GDB command
-`run'.
-
- To stop debugging the remote program, use the GDB `detach' command.
-
- To return control of the PC to its console, use `tip' or `cu' once
-again, after your GDB session has concluded, to attach to `EBMON'. You
-can then type the command `q' to shut down `EBMON', returning control
-to the DOS command-line interpreter. Type `CTTY con' to return command
-input to the main DOS console, and type `~.' to leave `tip' or `cu'.
-
-
-File: gdb.info, Node: Remote Log, Prev: gdb-EB29K, Up: EB29K Remote
-
-Remote log
-----------
-
- The `target amd-eb' command creates a file `eb.log' in the current
-working directory, to help debug problems with the connection.
-`eb.log' records all the output from `EBMON', including echoes of the
-commands sent to it. Running `tail -f' on this file in another window
-often helps to understand trouble with `EBMON', or unexpected events on
-the PC side of the connection.

-
-GDB with a Tandem ST2000
-------------------------
-
- To connect your ST2000 to the host system, see the manufacturer's
-manual. Once the ST2000 is physically attached, you can run
-
- target st2000 DEV SPEED
-
-to establish it as your debugging environment. DEV is normally the
-name of a serial device, such as `/dev/ttya', connected to the ST2000
-via a serial line. You can instead specify DEV as a TCP connection
-(for example, to a serial line attached via a terminal concentrator)
-using the syntax `HOSTNAME:PORTNUMBER'.
-
- The `load' and `attach' commands are *not* defined for this target;
-you must load your program into the ST2000 as you normally would for
-standalone operation. GDB will read debugging information (such as
-symbols) from a separate, debugging version of the program available on
-your host computer.
-
- These auxiliary GDB commands are available to help you with the
-ST2000 environment:
-
-`st2000 COMMAND'
- Send a COMMAND to the STDBUG monitor. See the manufacturer's
- manual for available commands.
-
-`connect'
- Connect the controlling terminal to the STDBUG command monitor.
- When you are done interacting with STDBUG, typing either of two
- character sequences will get you back to the GDB command prompt:
- `RET~.' (Return, followed by tilde and period) or `RET~C-d'
- (Return, followed by tilde and control-D).
-
-
-File: gdb.info, Node: VxWorks Remote, Next: ST2000 Remote, Prev: EB29K Remote, Up: Remote
-
-GDB and VxWorks
----------------
-
- GDB enables developers to spawn and debug tasks running on networked
-VxWorks targets from a Unix host. Already-running tasks spawned from
-the VxWorks shell can also be debugged. GDB uses code that runs on
-both the Unix host and on the VxWorks target. The program `gdb' is
-installed and executed on the Unix host. (It may be installed with the
-name `vxgdb', to distinguish it from a GDB for debugging programs on
-the host itself.)
-
- The following information on connecting to VxWorks was current when
-this manual was produced; newer releases of VxWorks may use revised
-procedures.
-
- The remote debugging interface (RDB) routines are installed and
-executed on the VxWorks target. These routines are included in the
-VxWorks library `rdb.a' and are incorporated into the system image when
-source-level debugging is enabled in the VxWorks configuration.
-
- If you wish, you can define `INCLUDE_RDB' in the VxWorks
-configuration file `configAll.h' to include the RDB interface routines
-and spawn the source debugging task `tRdbTask' when VxWorks is booted.
-For more information on configuring and remaking VxWorks, see the
-manufacturer's manual.
-
- Once you have included the RDB interface in your VxWorks system image
-and set your Unix execution search path to find GDB, you are ready to
-run GDB. From your Unix host, run `gdb' (or `vxgdb', depending on your
-installation).
-
- GDB comes up showing the prompt:
-
- (vxgdb)
-
-* Menu:
-
-* VxWorks Connection:: Connecting to VxWorks
-* VxWorks Download:: VxWorks download
-* VxWorks Attach:: Running tasks
-
-
-File: gdb.info, Node: VxWorks Connection, Next: VxWorks Download, Up: VxWorks Remote
-
-Connecting to VxWorks
----------------------
-
- The GDB command `target' lets you connect to a VxWorks target on the
-network. To connect to a target whose host name is "`tt'", type:
-
- (vxgdb) target vxworks tt
-
- GDB displays messages like these:
-
- Attaching remote machine across net...
- Connected to tt.
-
- GDB then attempts to read the symbol tables of any object modules
-loaded into the VxWorks target since it was last booted. GDB locates
-these files by searching the directories listed in the command search
-path (*note Your program's environment: Environment.); if it fails to
-find an object file, it displays a message such as:
-
- prog.o: No such file or directory.
-
- When this happens, add the appropriate directory to the search path
-with the GDB command `path', and execute the `target' command again.
-
-
-File: gdb.info, Node: VxWorks Download, Next: VxWorks Attach, Prev: VxWorks Connection, Up: VxWorks Remote
-
-VxWorks download
-----------------
-
- If you have connected to the VxWorks target and you want to debug an
-object that has not yet been loaded, you can use the GDB `load' command
-to download a file from Unix to VxWorks incrementally. The object file
-given as an argument to the `load' command is actually opened twice:
-first by the VxWorks target in order to download the code, then by GDB
-in order to read the symbol table. This can lead to problems if the
-current working directories on the two systems differ. If both systems
-have NFS mounted the same filesystems, you can avoid these problems by
-using absolute paths. Otherwise, it is simplest to set the working
-directory on both systems to the directory in which the object file
-resides, and then to reference the file by its name, without any path.
-For instance, a program `prog.o' may reside in `VXPATH/vw/demo/rdb' in
-VxWorks and in `HOSTPATH/vw/demo/rdb' on the host. To load this
-program, type this on VxWorks:
-
- -> cd "VXPATH/vw/demo/rdb"
-
- Then, in GDB, type:
-
- (vxgdb) cd HOSTPATH/vw/demo/rdb
- (vxgdb) load prog.o
-
- GDB displays a response similar to this:
-
- Reading symbol data from wherever/vw/demo/rdb/prog.o... done.
-
- You can also use the `load' command to reload an object module after
-editing and recompiling the corresponding source file. Note that this
-will cause GDB to delete all currently-defined breakpoints,
-auto-displays, and convenience variables, and to clear the value
-history. (This is necessary in order to preserve the integrity of
-debugger data structures that reference the target system's symbol
-table.)
-
-
-File: gdb.info, Node: VxWorks Attach, Prev: VxWorks Download, Up: VxWorks Remote
-
-Running tasks
--------------
-
- You can also attach to an existing task using the `attach' command as
-follows:
-
- (vxgdb) attach TASK
-
-where TASK is the VxWorks hexadecimal task ID. The task can be running
-or suspended when you attach to it. If running, it will be suspended at
-the time of attachment.
-

-
-GDB and Hitachi Microprocessors
--------------------------------
-
- GDB needs to know these things to talk to your Hitachi SH, H8/300,
-or H8/500:
-
- 1. that you want to use `target hms', the remote debugging interface
- for Hitachi microprocessors (this is the default when GDB is
- configured specifically for the Hitachi SH, H8/300, or H8/500);
-
- 2. what serial device connects your host to your Hitachi board (the
- first serial device available on your host is the default);
-
-
- Use the special `gdb' command `device PORT' if you need to
-explicitly set the serial device. The default PORT is the first
-available port on your host. This is only necessary on Unix hosts,
-where it is typically something like `/dev/ttya'.
-
- `gdb' has another special command to set the communications speed:
-`speed BPS'. This command also is only used from Unix hosts; on DOS
-hosts, set the line speed as usual from outside GDB with the DOS `mode'
-command (for instance, `mode com2:9600,n,8,1,p' for a 9600 bps
-connection).
-
- The `device' and `speed' commands are available only when you use a
-Unix host to debug your Hitachi microprocessor programs. If you use a
-DOS host, GDB depends on an auxiliary terminate-and-stay-resident
-program called `asynctsr' to communicate with the development board
-through a PC serial port. You must also use the DOS `mode' command to
-set up the serial port on the DOS side.
-
-
-File: gdb.info, Node: MIPS Remote, Next: Simulator, Prev: Hitachi Remote, Up: Remote
-
-GDB and remote MIPS boards
---------------------------
-
- GDB can use the MIPS remote debugging protocol to talk to a MIPS
-board attached to a serial line. This is available when you configure
-GDB with `--target=mips-idt-ecoff'.
-
- To run a program on the board, start up `gdb' with the name of your
-program as the argument. To connect to the board, use the command
-`target mips PORT', where PORT is the name of the serial port connected
-to the board. If the program has not already been downloaded to the
-board, you may use the `load' command to download it. You can then use
-all the usual GDB commands.
-
- You can also specify PORT as a TCP connection (for instance, to a
-serial line managed by a terminal concentrator), using the syntax
-`HOSTNAME:PORTNUMBER'.
-
- You can see some debugging information about communications with the
-board by setting the `remotedebug' variable. If you set it to 1 using
-`set remotedebug 1' every packet will be displayed. If you set it to 2
-every character will be displayed. You can check the current value at
-any time with the command `show remotedebug'.
-
- You can control the timeout used while waiting for a packet, in the
-MIPS remote protocol, with the `set timeout SECONDS' command. The
-default is 5 seconds. Similarly, you can control the timeout used while
-waiting for an acknowledgement of a packet with the `set
-retransmit-timeout SECONDS' command. The default is 3 seconds. You
-can inspect both values with `show timeout' and `show
-retransmit-timeout'. (These commands are *only* available when GDB is
-configured for `--target=mips-idt-ecoff'.)
-
- If your target board does not support the MIPS floating point
-coprocessor, you should use the command `set mipsfpu off' (you may wish
-to put this in your .gdbinit file). This tells GDB how to find the
-return value of functions which return floating point values. It also
-allows GDB to avoid saving the floating point registers when calling
-functions on the board.
-
-
-File: gdb.info, Node: Simulator, Prev: MIPS Remote, Up: Remote
-
-Simulated CPU target
---------------------
-
- For some configurations, GDB includes a CPU simulator that you can
-use instead of a hardware CPU to debug your programs. Currently, a
-simulator is available when GDB is configured to debug Zilog Z8000 or
-Hitachi microprocessor targets.
-
- For the Z8000 family, `target sim' simulates either the Z8002 (the
-unsegmented variant of the Z8000 architecture) or the Z8001 (the
-segmented variant). The simulator recognizes which architecture is
-appropriate by inspecting the object code.
-
-`target sim'
- Debug programs on a simulated CPU (which CPU depends on the GDB
- configuration)
-
-After specifying this target, you can debug programs for the simulated
-CPU in the same style as programs for your host computer; use the
-`file' command to load a new program image, the `run' command to run
-your program, and so on.
-
- As well as making available all the usual machine registers (see
-`info reg'), this debugging target provides three additional items of
-information as specially named registers:
-
-`cycles'
- Counts clock-ticks in the simulator.
-
-`insts'
- Counts instructions run in the simulator.
-
-`time'
- Execution time in 60ths of a second.
-
- You can refer to these values in GDB expressions with the usual
-conventions; for example, `b fputc if $cycles>5000' sets a conditional
-breakpoint that will suspend only after at least 5000 simulated clock
-ticks.

-Prompt
-======
-
- GDB indicates its readiness to read a command by printing a string
-called the "prompt". This string is normally `(gdb)'. You can change
-the prompt string with the `set prompt' command. For instance, when
-debugging GDB with GDB, it is useful to change the prompt in one of the
-GDB sessions so that you can always tell which one you are talking to.
-
-`set prompt NEWPROMPT'
- Directs GDB to use NEWPROMPT as its prompt string henceforth.
-
-`show prompt'
- Prints a line of the form: `Gdb's prompt is: YOUR-PROMPT'
-
-
-File: gdb.info, Node: Editing, Next: History, Prev: Prompt, Up: Controlling GDB
-
-Command editing
-===============
-
- GDB reads its input commands via the "readline" interface. This GNU
-library provides consistent behavior for programs which provide a
-command line interface to the user. Advantages are `emacs'-style or
-`vi'-style inline editing of commands, `csh'-like history substitution,
-and a storage and recall of command history across debugging sessions.
-
- You may control the behavior of command line editing in GDB with the
-command `set'.
-
-`set editing'
-`set editing on'
- Enable command line editing (enabled by default).
-
-`set editing off'
- Disable command line editing.
-
-`show editing'
- Show whether command line editing is enabled.
-
-
-File: gdb.info, Node: History, Next: Screen Size, Prev: Editing, Up: Controlling GDB
-
-Command history
-===============
-
- GDB can keep track of the commands you type during your debugging
-sessions, so that you can be certain of precisely what happened. Use
-these commands to manage the GDB command history facility.
-
-`set history filename FNAME'
- Set the name of the GDB command history file to FNAME. This is
- the file from which GDB will read an initial command history list
- or to which it will write this list when it exits. This list is
- accessed through history expansion or through the history command
- editing characters listed below. This file defaults to the value
- of the environment variable `GDBHISTFILE', or to `./.gdb_history'
- if this variable is not set.
-
-`set history save'
-`set history save on'
- Record command history in a file, whose name may be specified with
- the `set history filename' command. By default, this option is
- disabled.
-
-`set history save off'
- Stop recording command history in a file.
-
-`set history size SIZE'
- Set the number of commands which GDB will keep in its history list.
- This defaults to the value of the environment variable `HISTSIZE',
- or to 256 if this variable is not set.
-
- History expansion assigns special meaning to the character `!'.
-
- Since `!' is also the logical not operator in C, history expansion
-is off by default. If you decide to enable history expansion with the
-`set history expansion on' command, you may sometimes need to follow
-`!' (when it is used as logical not, in an expression) with a space or
-a tab to prevent it from being expanded. The readline history
-facilities will not attempt substitution on the strings `!=' and `!(',
-even when history expansion is enabled.
-
- The commands to control history expansion are:
-
-`set history expansion on'
-`set history expansion'
- Enable history expansion. History expansion is off by default.
-
-`set history expansion off'
- Disable history expansion.
-
- The readline code comes with more complete documentation of
- editing and history expansion features. Users unfamiliar with
- `emacs' or `vi' may wish to read it.
-
-`show history'
-`show history filename'
-`show history save'
-`show history size'
-`show history expansion'
- These commands display the state of the GDB history parameters.
- `show history' by itself displays all four states.
-
-`show commands'
- Display the last ten commands in the command history.
-
-`show commands N'
- Print ten commands centered on command number N.
-
-`show commands +'
- Print ten commands just after the commands last printed.

-Screen size
-===========
-
- Certain commands to GDB may produce large amounts of information
-output to the screen. To help you read all of it, GDB pauses and asks
-you for input at the end of each page of output. Type RET when you
-want to continue the output, or `q' to discard the remaining output.
-Also, the screen width setting determines when to wrap lines of output.
-Depending on what is being printed, GDB tries to break the line at a
-readable place, rather than simply letting it overflow onto the
-following line.
-
- Normally GDB knows the size of the screen from the termcap data base
-together with the value of the `TERM' environment variable and the
-`stty rows' and `stty cols' settings. If this is not correct, you can
-override it with the `set height' and `set width' commands:
-
-`set height LPP'
-`show height'
-`set width CPL'
-`show width'
- These `set' commands specify a screen height of LPP lines and a
- screen width of CPL characters. The associated `show' commands
- display the current settings.
-
- If you specify a height of zero lines, GDB will not pause during
- output no matter how long the output is. This is useful if output
- is to a file or to an editor buffer.
-
- Likewise, you can specify `set width 0' to prevent GDB from
- wrapping its output.

-Numbers
-=======
-
- You can always enter numbers in octal, decimal, or hexadecimal in
-GDB by the usual conventions: octal numbers begin with `0', decimal
-numbers end with `.', and hexadecimal numbers begin with `0x'. Numbers
-that begin with none of these are, by default, entered in base 10;
-likewise, the default display for numbers--when no particular format is
-specified--is base 10. You can change the default base for both input
-and output with the `set radix' command.
-
-`set radix BASE'
- Set the default base for numeric input and display. Supported
- choices for BASE are decimal 8, 10, or 16. BASE must itself be
- specified either unambiguously or using the current default radix;
- for example, any of
-
- set radix 012
- set radix 10.
- set radix 0xa
-
- will set the base to decimal. On the other hand, `set radix 10'
- will leave the radix unchanged no matter what it was.
-
-`show radix'
- Display the current default base for numeric input and display.

-
-Optional warnings and messages
-==============================
-
- By default, GDB is silent about its inner workings. If you are
-running on a slow machine, you may want to use the `set verbose'
-command. It will make GDB tell you when it does a lengthy internal
-operation, so you will not think it has crashed.
-
- Currently, the messages controlled by `set verbose' are those which
-announce that the symbol table for a source file is being read; see
-`symbol-file' in *Note Commands to specify files: Files.
-
-`set verbose on'
- Enables GDB output of certain informational messages.
-
-`set verbose off'
- Disables GDB output of certain informational messages.
-
-`show verbose'
- Displays whether `set verbose' is on or off.
-
- By default, if GDB encounters bugs in the symbol table of an object
-file, it is silent; but if you are debugging a compiler, you may find
-this information useful (*note Errors reading symbol files: Symbol
-Errors.).
-
-`set complaints LIMIT'
- Permits GDB to output LIMIT complaints about each type of unusual
- symbols before becoming silent about the problem. Set LIMIT to
- zero to suppress all complaints; set it to a large number to
- prevent complaints from being suppressed.
-
-`show complaints'
- Displays how many symbol complaints GDB is permitted to produce.
-
- By default, GDB is cautious, and asks what sometimes seems to be a
-lot of stupid questions to confirm certain commands. For example, if
-you try to run a program which is already running:
-
- (gdb) run
- The program being debugged has been started already.
- Start it from the beginning? (y or n)
-
- If you are willing to unflinchingly face the consequences of your own
-commands, you can disable this "feature":
-
-`set confirm off'
- Disables confirmation requests.
-
-`set confirm on'
- Enables confirmation requests (the default).
-
-`show confirm'
- Displays state of confirmation requests.
-
- Some systems allow individual object files that make up your program
-to be replaced without stopping and restarting your program. For
-example, in VxWorks you can simply recompile a defective object file
-and keep on running. If you are running on one of these systems, you
-can allow GDB to reload the symbols for automatically relinked modules:
-
-`set symbol-reloading on'
- Replace symbol definitions for the corresponding source file when
- an object file with a particular name is seen again.
-
-`set symbol-reloading off'
- Do not replace symbol definitions when re-encountering object
- files of the same name. This is the default state; if you are not
- running on a system that permits automatically relinking modules,
- you should leave `symbol-reloading' off, since otherwise GDB may
- discard symbols when linking large programs, that may contain
- several modules (from different directories or libraries) with the
- same name.
-
-`show symbol-reloading'
- Show the current `on' or `off' setting.

-Canned Sequences of Commands
-****************************
-
- Aside from breakpoint commands (*note Breakpoint command lists:
-Break Commands.), GDB provides two ways to store sequences of commands
-for execution as a unit: user-defined commands and command files.
-
-* Menu:
-
-* Define:: User-defined commands
-* Hooks:: User-defined command hooks
-* Command Files:: Command files
-* Output:: Commands for controlled output
-
-
-File: gdb.info, Node: Define, Next: Hooks, Up: Sequences
-
-User-defined commands
-=====================
-
- A "user-defined command" is a sequence of GDB commands to which you
-assign a new name as a command. This is done with the `define' command.
-
-`define COMMANDNAME'
- Define a command named COMMANDNAME. If there is already a command
- by that name, you are asked to confirm that you want to redefine
- it.
-
- The definition of the command is made up of other GDB command
- lines, which are given following the `define' command. The end of
- these commands is marked by a line containing `end'.
-
-`document COMMANDNAME'
- Give documentation to the user-defined command COMMANDNAME. The
- command COMMANDNAME must already be defined. This command reads
- lines of documentation just as `define' reads the lines of the
- command definition, ending with `end'. After the `document'
- command is finished, `help' on command COMMANDNAME will print the
- documentation you have specified.
-
- You may use the `document' command again to change the
- documentation of a command. Redefining the command with `define'
- does not change the documentation.
-
-`help user-defined'
- List all user-defined commands, with the first line of the
- documentation (if any) for each.
-
-`show user'
-`show user COMMANDNAME'
- Display the GDB commands used to define COMMANDNAME (but not its
- documentation). If no COMMANDNAME is given, display the
- definitions for all user-defined commands.
-
- User-defined commands do not take arguments. When they are
-executed, the commands of the definition are not printed. An error in
-any command stops execution of the user-defined command.
-
- Commands that would ask for confirmation if used interactively
-proceed without asking when used inside a user-defined command. Many
-GDB commands that normally print messages to say what they are doing
-omit the messages when used in a user-defined command.
-
-
-File: gdb.info, Node: Hooks, Next: Command Files, Prev: Define, Up: Sequences
-
-User-defined command hooks
-==========================
-
- You may define *hooks*, which are a special kind of user-defined
-command. Whenever you run the command `foo', if the user-defined
-command `hook-foo' exists, it is executed (with no arguments) before
-that command.
-
- In addition, a pseudo-command, `stop' exists. Defining
-(`hook-stop') makes the associated commands execute every time
-execution stops in your program: before breakpoint commands are run,
-displays are printed, or the stack frame is printed.
-
- For example, to ignore `SIGALRM' signals while single-stepping, but
-treat them normally during normal execution, you could define:
-
- define hook-stop
- handle SIGALRM nopass
- end
-
- define hook-run
- handle SIGALRM pass
- end
-
- define hook-continue
- handle SIGLARM pass
- end
-
- You can define a hook for any single-word command in GDB, but not
-for command aliases; you should define a hook for the basic command
-name, e.g. `backtrace' rather than `bt'. If an error occurs during
-the execution of your hook, execution of GDB commands stops and GDB
-issues a prompt (before the command that you actually typed had a
-chance to run).
-
- If you try to define a hook which does not match any known command,
-you will get a warning from the `define' command.
-
-
-File: gdb.info, Node: Command Files, Next: Output, Prev: Hooks, Up: Sequences
-
-Command files
-=============
-
- A command file for GDB is a file of lines that are GDB commands.
-Comments (lines starting with `#') may also be included. An empty line
-in a command file does nothing; it does not mean to repeat the last
-command, as it would from the terminal.
-
- When you start GDB, it automatically executes commands from its
-"init files". These are files named `.gdbinit'. GDB reads the init
-file (if any) in your home directory and then the init file (if any) in
-the current working directory. (The init files are not executed if you
-use the `-nx' option; *note Choosing modes: Mode Options..)
-
- On some configurations of GDB, the init file is known by a different
-name (these are typically environments where a specialized form of GDB
-may need to coexist with other forms, hence a different name for the
-specialized version's init file). These are the environments with
-special init file names:
-
- * VxWorks (Wind River Systems real-time OS): `.vxgdbinit'
-
- * OS68K (Enea Data Systems real-time OS): `.os68gdbinit'
-
- * ES-1800 (Ericsson Telecom AB M68000 emulator): `.esgdbinit'
-
- You can also request the execution of a command file with the
-`source' command:
-
-`source FILENAME'
- Execute the command file FILENAME.
-
- The lines in a command file are executed sequentially. They are not
-printed as they are executed. An error in any command terminates
-execution of the command file.
-
- Commands that would ask for confirmation if used interactively
-proceed without asking when used in a command file. Many GDB commands
-that normally print messages to say what they are doing omit the
-messages when called from command files.
-
-
-File: gdb.info, Node: Output, Prev: Command Files, Up: Sequences
-
-Commands for controlled output
-==============================
-
- During the execution of a command file or a user-defined command,
-normal GDB output is suppressed; the only output that appears is what is
-explicitly printed by the commands in the definition. This section
-describes three commands useful for generating exactly the output you
-want.
-
-`echo TEXT'
- Print TEXT. Nonprinting characters can be included in TEXT using
- C escape sequences, such as `\n' to print a newline. *No newline
- will be printed unless you specify one.* In addition to the
- standard C escape sequences, a backslash followed by a space
- stands for a space. This is useful for displaying a string with
- spaces at the beginning or the end, since leading and trailing
- spaces are otherwise trimmed from all arguments. To print ` and
- foo = ', use the command `echo \ and foo = \ '.
-
- A backslash at the end of TEXT can be used, as in C, to continue
- the command onto subsequent lines. For example,
-
- echo This is some text\n\
- which is continued\n\
- onto several lines.\n
-
- produces the same output as
-
- echo This is some text\n
- echo which is continued\n
- echo onto several lines.\n
-
-`output EXPRESSION'
- Print the value of EXPRESSION and nothing but that value: no
- newlines, no `$NN = '. The value is not entered in the value
- history either. *Note Expressions: Expressions, for more
- information on expressions.
-
-`output/FMT EXPRESSION'
- Print the value of EXPRESSION in format FMT. You can use the same
- formats as for `print'. *Note Output formats: Output Formats, for
- more information.
-
-`printf STRING, EXPRESSIONS...'
- Print the values of the EXPRESSIONS under the control of STRING.
- The EXPRESSIONS are separated by commas and may be either numbers
- or pointers. Their values are printed as specified by STRING,
- exactly as if your program were to execute the C subroutine
-
- printf (STRING, EXPRESSIONS...);
-
- For example, you can print two values in hex like this:
-
- printf "foo, bar-foo = 0x%x, 0x%x\n", foo, bar-foo
-
- The only backslash-escape sequences that you can use in the format
- string are the simple ones that consist of backslash followed by a
- letter.

-
-Using GDB under GNU Emacs
-*************************
-
- A special interface allows you to use GNU Emacs to view (and edit)
-the source files for the program you are debugging with GDB.
-
- To use this interface, use the command `M-x gdb' in Emacs. Give the
-executable file you want to debug as an argument. This command starts
-GDB as a subprocess of Emacs, with input and output through a newly
-created Emacs buffer.
-
- Using GDB under Emacs is just like using GDB normally except for two
-things:
-
- * All "terminal" input and output goes through the Emacs buffer.
-
- This applies both to GDB commands and their output, and to the input
-and output done by the program you are debugging.
-
- This is useful because it means that you can copy the text of
-previous commands and input them again; you can even use parts of the
-output in this way.
-
- All the facilities of Emacs' Shell mode are available for interacting
-with your program. In particular, you can send signals the usual
-way--for example, `C-c C-c' for an interrupt, `C-c C-z' for a stop.
-
- * GDB displays source code through Emacs.
-
- Each time GDB displays a stack frame, Emacs automatically finds the
-source file for that frame and puts an arrow (`=>') at the left margin
-of the current line. Emacs uses a separate buffer for source display,
-and splits the screen to show both your GDB session and the source.
-
- Explicit GDB `list' or search commands still produce output as
-usual, but you probably will have no reason to use them.
-
- *Warning:* If the directory where your program resides is not your
- current directory, it can be easy to confuse Emacs about the
- location of the source files, in which case the auxiliary display
- buffer will not appear to show your source. GDB can find programs
- by searching your environment's `PATH' variable, so the GDB input
- and output session will proceed normally; but Emacs does not get
- enough information back from GDB to locate the source files in
- this situation. To avoid this problem, either start GDB mode from
- the directory where your program resides, or specify a full path
- name when prompted for the `M-x gdb' argument.
-
- A similar confusion can result if you use the GDB `file' command to
- switch to debugging a program in some other location, from an
- existing GDB buffer in Emacs.
-
- By default, `M-x gdb' calls the program called `gdb'. If you need
-to call GDB by a different name (for example, if you keep several
-configurations around, with different names) you can set the Emacs
-variable `gdb-command-name'; for example,
-
- (setq gdb-command-name "mygdb")
-
-(preceded by `ESC ESC', or typed in the `*scratch*' buffer, or in your
-`.emacs' file) will make Emacs call the program named "`mygdb'" instead.
-
- In the GDB I/O buffer, you can use these special Emacs commands in
-addition to the standard Shell mode commands:
-
-`C-h m'
- Describe the features of Emacs' GDB Mode.
-
-`M-s'
- Execute to another source line, like the GDB `step' command; also
- update the display window to show the current file and location.
-
-`M-n'
- Execute to next source line in this function, skipping all function
- calls, like the GDB `next' command. Then update the display window
- to show the current file and location.
-
-`M-i'
- Execute one instruction, like the GDB `stepi' command; update
- display window accordingly.
-
-`M-x gdb-nexti'
- Execute to next instruction, using the GDB `nexti' command; update
- display window accordingly.
-
-`C-c C-f'
- Execute until exit from the selected stack frame, like the GDB
- `finish' command.
-
-`M-c'
- Continue execution of your program, like the GDB `continue'
- command.
-
- *Warning:* In Emacs v19, this command is `C-c C-p'.
-
-`M-u'
- Go up the number of frames indicated by the numeric argument
- (*note Numeric Arguments: (emacs)Arguments.), like the GDB `up'
- command.
-
- *Warning:* In Emacs v19, this command is `C-c C-u'.
-
-`M-d'
- Go down the number of frames indicated by the numeric argument,
- like the GDB `down' command.
-
- *Warning:* In Emacs v19, this command is `C-c C-d'.
-
-`C-x &'
- Read the number where the cursor is positioned, and insert it at
- the end of the GDB I/O buffer. For example, if you wish to
- disassemble code around an address that was displayed earlier,
- type `disassemble'; then move the cursor to the address display,
- and pick up the argument for `disassemble' by typing `C-x &'.
-
- You can customize this further by defining elements of the list
- `gdb-print-command'; once it is defined, you can format or
- otherwise process numbers picked up by `C-x &' before they are
- inserted. A numeric argument to `C-x &' will both indicate that
- you wish special formatting, and act as an index to pick an
- element of the list. If the list element is a string, the number
- to be inserted is formatted using the Emacs function `format';
- otherwise the number is passed as an argument to the corresponding
- list element.
-
- In any source file, the Emacs command `C-x SPC' (`gdb-break') tells
-GDB to set a breakpoint on the source line point is on.
-
- If you accidentally delete the source-display buffer, an easy way to
-get it back is to type the command `f' in the GDB buffer, to request a
-frame display; when you run under Emacs, this will recreate the source
-buffer if necessary to show you the context of the current frame.
-
- The source files displayed in Emacs are in ordinary Emacs buffers
-which are visiting the source files in the usual way. You can edit the
-files with these buffers if you wish; but keep in mind that GDB
-communicates with Emacs in terms of line numbers. If you add or delete
-lines from the text, the line numbers that GDB knows will cease to
-correspond properly with the code.

-Reporting Bugs in GDB
-*********************
-
- Your bug reports play an essential role in making GDB reliable.
-
- Reporting a bug may help you by bringing a solution to your problem,
-or it may not. But in any case the principal function of a bug report
-is to help the entire community by making the next version of GDB work
-better. Bug reports are your contribution to the maintenance of GDB.
-
- In order for a bug report to serve its purpose, you must include the
-information that enables us to fix the bug.

-
-Have you found a bug?
-=====================
-
- If you are not sure whether you have found a bug, here are some
-guidelines:
-
- * If the debugger gets a fatal signal, for any input whatever, that
- is a GDB bug. Reliable debuggers never crash.
-
- * If GDB produces an error message for valid input, that is a bug.
-
- * If GDB does not produce an error message for invalid input, that
- is a bug. However, you should note that your idea of "invalid
- input" might be our idea of "an extension" or "support for
- traditional practice".
-
- * If you are an experienced user of debugging tools, your suggestions
- for improvement of GDB are welcome in any case.

-How to report bugs
-==================
-
- A number of companies and individuals offer support for GNU products.
-If you obtained GDB from a support organization, we recommend you
-contact that organization first.
-
- You can find contact information for many support companies and
-individuals in the file `etc/SERVICE' in the GNU Emacs distribution.
-
- In any event, we also recommend that you send bug reports for GDB to
-one of these addresses:
-
- bug-gdb@prep.ai.mit.edu
- {ucbvax|mit-eddie|uunet}!prep.ai.mit.edu!bug-gdb
-
- *Do not send bug reports to `info-gdb', or to `help-gdb', or to any
-newsgroups.* Most users of GDB do not want to receive bug reports.
-Those that do, have arranged to receive `bug-gdb'.
-
- The mailing list `bug-gdb' has a newsgroup `gnu.gdb.bug' which
-serves as a repeater. The mailing list and the newsgroup carry exactly
-the same messages. Often people think of posting bug reports to the
-newsgroup instead of mailing them. This appears to work, but it has one
-problem which can be crucial: a newsgroup posting often lacks a mail
-path back to the sender. Thus, if we need to ask for more information,
-we may be unable to reach you. For this reason, it is better to send
-bug reports to the mailing list.
-
- As a last resort, send bug reports on paper to:
-
- GNU Debugger Bugs
- Free Software Foundation
- 545 Tech Square
- Cambridge, MA 02139
-
- The fundamental principle of reporting bugs usefully is this:
-*report all the facts*. If you are not sure whether to state a fact or
-leave it out, state it!
-
- Often people omit facts because they think they know what causes the
-problem and assume that some details do not matter. Thus, you might
-assume that the name of the variable you use in an example does not
-matter. Well, probably it does not, but one cannot be sure. Perhaps
-the bug is a stray memory reference which happens to fetch from the
-location where that name is stored in memory; perhaps, if the name were
-different, the contents of that location would fool the debugger into
-doing the right thing despite the bug. Play it safe and give a
-specific, complete example. That is the easiest thing for you to do,
-and the most helpful.
-
- Keep in mind that the purpose of a bug report is to enable us to fix
-the bug if it is new to us. It is not as important as what happens if
-the bug is already known. Therefore, always write your bug reports on
-the assumption that the bug has not been reported previously.
-
- Sometimes people give a few sketchy facts and ask, "Does this ring a
-bell?" Those bug reports are useless, and we urge everyone to *refuse
-to respond to them* except to chide the sender to report bugs properly.
-
- To enable us to fix the bug, you should include all these things:
-
- * The version of GDB. GDB announces it if you start with no
- arguments; you can also print it at any time using `show version'.
-
- Without this, we will not know whether there is any point in
- looking for the bug in the current version of GDB.
-
- * The type of machine you are using, and the operating system name
- and version number.
-
- * What compiler (and its version) was used to compile GDB--e.g.
- "gcc-2.0".
-
- * What compiler (and its version) was used to compile the program you
- are debugging--e.g. "gcc-2.0".
-
- * The command arguments you gave the compiler to compile your
- example and observe the bug. For example, did you use `-O'? To
- guarantee you will not omit something important, list them all. A
- copy of the Makefile (or the output from make) is sufficient.
-
- If we were to try to guess the arguments, we would probably guess
- wrong and then we might not encounter the bug.
-
- * A complete input script, and all necessary source files, that will
- reproduce the bug.
-
- * A description of what behavior you observe that you believe is
- incorrect. For example, "It gets a fatal signal."
-
- Of course, if the bug is that GDB gets a fatal signal, then we will
- certainly notice it. But if the bug is incorrect output, we might
- not notice unless it is glaringly wrong. We are human, after all.
- You might as well not give us a chance to make a mistake.
-
- Even if the problem you experience is a fatal signal, you should
- still say so explicitly. Suppose something strange is going on,
- such as, your copy of GDB is out of synch, or you have encountered
- a bug in the C library on your system. (This has happened!) Your
- copy might crash and ours would not. If you told us to expect a
- crash, then when ours fails to crash, we would know that the bug
- was not happening for us. If you had not told us to expect a
- crash, then we would not be able to draw any conclusion from our
- observations.
-
- * If you wish to suggest changes to the GDB source, send us context
- diffs. If you even discuss something in the GDB source, refer to
- it by context, not by line number.
-
- The line numbers in our development sources will not match those
- in your sources. Your line numbers would convey no useful
- information to us.
-
- Here are some things that are not necessary:
-
- * A description of the envelope of the bug.
-
- Often people who encounter a bug spend a lot of time investigating
- which changes to the input file will make the bug go away and which
- changes will not affect it.
-
- This is often time consuming and not very useful, because the way
- we will find the bug is by running a single example under the
- debugger with breakpoints, not by pure deduction from a series of
- examples. We recommend that you save your time for something else.
-
- Of course, if you can find a simpler example to report *instead*
- of the original one, that is a convenience for us. Errors in the
- output will be easier to spot, running under the debugger will take
- less time, etc.
-
- However, simplification is not vital; if you do not want to do
- this, report the bug anyway and send us the entire test case you
- used.
-
- * A patch for the bug.
-
- A patch for the bug does help us if it is a good one. But do not
- omit the necessary information, such as the test case, on the
- assumption that a patch is all we need. We might see problems
- with your patch and decide to fix the problem another way, or we
- might not understand it at all.
-
- Sometimes with a program as complicated as GDB it is very hard to
- construct an example that will make the program follow a certain
- path through the code. If you do not send us the example, we will
- not be able to construct one, so we will not be able to verify
- that the bug is fixed.
-
- And if we cannot understand what bug you are trying to fix, or why
- your patch should be an improvement, we will not install it. A
- test case will help us to understand.
-
- * A guess about what the bug is or what it depends on.
-
- Such guesses are usually wrong. Even we cannot guess right about
- such things without first using the debugger to find the facts.

-Introduction to Line Editing
-============================
-
- The following paragraphs describe the notation we use to represent
-keystrokes.
-
- The text C-k is read as `Control-K' and describes the character
-produced when the Control key is depressed and the k key is struck.
-
- The text M-k is read as `Meta-K' and describes the character
-produced when the meta key (if you have one) is depressed, and the k
-key is struck. If you do not have a meta key, the identical keystroke
-can be generated by typing ESC first, and then typing k. Either
-process is known as "metafying" the k key.
-
- The text M-C-k is read as `Meta-Control-k' and describes the
-character produced by "metafying" C-k.
-
- In addition, several keys have their own names. Specifically, DEL,
-ESC, LFD, SPC, RET, and TAB all stand for themselves when seen in this
-text, or in an init file (*note Readline Init File::., for more info).

-Readline Interaction
-====================
-
- Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled. The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line. Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections. Then, when you are satisfied with
-the line, you simply press RETURN. You do not have to be at the end of
-the line to press RETURN; the entire line is accepted regardless of the
-location of the cursor within the line.

-
-Readline Bare Essentials
-------------------------
-
- In order to enter characters into the line, simply type them. The
-typed character appears where the cursor was, and then the cursor moves
-one space to the right. If you mistype a character, you can use DEL to
-back up, and delete the mistyped character.
-
- Sometimes you may miss typing a character that you wanted to type,
-and not notice your error until you have typed several other
-characters. In that case, you can type C-b to move the cursor to the
-left, and then correct your mistake. Aftwerwards, you can move the
-cursor to the right with C-f.
-
- When you add text in the middle of a line, you will notice that
-characters to the right of the cursor get `pushed over' to make room
-for the text that you have inserted. Likewise, when you delete text
-behind the cursor, characters to the right of the cursor get `pulled
-back' to fill in the blank space created by the removal of the text. A
-list of the basic bare essentials for editing the text of an input line
-follows.
-
-C-b
- Move back one character.
-
-C-f
- Move forward one character.
-
-DEL
- Delete the character to the left of the cursor.
-
-C-d
- Delete the character underneath the cursor.
-
-Printing characters
- Insert itself into the line at the cursor.
-
-C-_
- Undo the last thing that you did. You can undo all the way back
- to an empty line.
-

-
-Readline Movement Commands
---------------------------
-
- The above table describes the most basic possible keystrokes that
-you need in order to do editing of the input line. For your
-convenience, many other commands have been added in addition to C-b,
-C-f, C-d, and DEL. Here are some commands for moving more rapidly
-about the line.
-
-C-a
- Move to the start of the line.
-
-C-e
- Move to the end of the line.
-
-M-f
- Move forward a word.
-
-M-b
- Move backward a word.
-
-C-l
- Clear the screen, reprinting the current line at the top.
-
- Notice how C-f moves forward a character, while M-f moves forward a
-word. It is a loose convention that control keystrokes operate on
-characters while meta keystrokes operate on words.
-

-
-Readline Killing Commands
--------------------------
-
- "Killing" text means to delete the text from the line, but to save
-it away for later use, usually by "yanking" it back into the line. If
-the description for a command says that it `kills' text, then you can
-be sure that you can get the text back in a different (or the same)
-place later.
-
- Here is the list of commands for killing text.
-
-C-k
- Kill the text from the current cursor position to the end of the
- line.
-
-M-d
- Kill from the cursor to the end of the current word, or if between
- words, to the end of the next word.
-
-M-DEL
- Kill from the cursor to the start of the previous word, or if
- between words, to the start of the previous word.
-
-C-w
- Kill from the cursor to the previous whitespace. This is
- different than M-DEL because the word boundaries differ.
-
- And, here is how to "yank" the text back into the line. Yanking is
-
-C-y
- Yank the most recently killed text back into the buffer at the
- cursor.
-
-M-y
- Rotate the kill-ring, and yank the new top. You can only do this
- if the prior command is C-y or M-y.
-
- When you use a kill command, the text is saved in a "kill-ring".
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it in one clean sweep. The kill
-ring is not line specific; the text that you killed on a previously
-typed line is available to be yanked back later, when you are typing
-another line.
-
-
-File: gdb.info, Node: Readline Arguments, Prev: Readline Killing Commands, Up: Readline Interaction
-
-Readline Arguments
-------------------
-
- You can pass numeric arguments to Readline commands. Sometimes the
-argument acts as a repeat count, other times it is the sign of the
-argument that is significant. If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction. For example, to kill text back to the
-start of the line, you might type M- C-k.
-
- The general way to pass numeric arguments to a command is to type
-meta digits before the command. If the first `digit' you type is a
-minus sign (-), then the sign of the argument will be negative. Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command. For example, to give
-the C-d command an argument of 10, you could type M-1 0 C-d.

-
-Readline Init File
-==================
-
- Although the Readline library comes with a set of Emacs-like
-keybindings, it is possible that you would like to use a different set
-of keybindings. You can customize programs that use Readline by putting
-commands in an "init" file in your home directory. The name of this
-file is `~/.inputrc'.
-
- When a program which uses the Readline library starts up, the
-`~/.inputrc' file is read, and the keybindings are set.
-
- In addition, the C-x C-r command re-reads this init file, thus
-incorporating any changes that you might have made to it.
-
-* Menu:
-
-* Readline Init Syntax:: Syntax for the commands in `~/.inputrc'.
-* Readline Vi Mode:: Switching to `vi' mode in Readline.
-
-
-File: gdb.info, Node: Readline Init Syntax, Next: Readline Vi Mode, Up: Readline Init File
-
-Readline Init Syntax
---------------------
-
- There are only four constructs allowed in the `~/.inputrc' file:
-
-Variable Settings
- You can change the state of a few variables in Readline. You do
- this by using the `set' command within the init file. Here is how
- you would specify that you wish to use Vi line editing commands:
-
- set editing-mode vi
-
- Right now, there are only a few variables which can be set; so few
- in fact, that we just iterate them here:
-
- `editing-mode'
- The `editing-mode' variable controls which editing mode you
- are using. By default, GNU Readline starts up in Emacs
- editing mode, where the keystrokes are most similar to Emacs.
- This variable can either be set to `emacs' or `vi'.
-
- `horizontal-scroll-mode'
- This variable can either be set to `On' or `Off'. Setting it
- to `On' means that the text of the lines that you edit will
- scroll horizontally on a single screen line when they are
- larger than the width of the screen, instead of wrapping onto
- a new screen line. By default, this variable is set to `Off'.
-
- `mark-modified-lines'
- This variable when set to `On', says to display an asterisk
- (`*') at the starts of history lines which have been modified.
- This variable is off by default.
-
- `prefer-visible-bell'
- If this variable is set to `On' it means to use a visible
- bell if one is available, rather than simply ringing the
- terminal bell. By default, the value is `Off'.
-
-Key Bindings
- The syntax for controlling keybindings in the `~/.inputrc' file is
- simple. First you have to know the name of the command that you
- want to change. The following pages contain tables of the command
- name, the default keybinding, and a short description of what the
- command does.
-
- Once you know the name of the command, simply place the name of
- the key you wish to bind the command to, a colon, and then the
- name of the command on a line in the `~/.inputrc' file. The name
- of the key can be expressed in different ways, depending on which
- is most comfortable for you.
-
- KEYNAME: FUNCTION-NAME or MACRO
- KEYNAME is the name of a key spelled out in English. For
- example:
- Control-u: universal-argument
- Meta-Rubout: backward-kill-word
- Control-o: ">&output"
-
- In the above example, C-u is bound to the function
- `universal-argument', and C-o is bound to run the macro
- expressed on the right hand side (that is, to insert the text
- `>&output' into the line).
-
- "KEYSEQ": FUNCTION-NAME or MACRO
- KEYSEQ differs from KEYNAME above in that strings denoting an
- entire key sequence can be specified. Simply place the key
- sequence in double quotes. GNU Emacs style key escapes can
- be used, as in the following example:
-
- "\C-u": universal-argument
- "\C-x\C-r": re-read-init-file
- "\e[11~": "Function Key 1"
-
- In the above example, C-u is bound to the function
- `universal-argument' (just as it was in the first example),
- C-x C-r is bound to the function `re-read-init-file', and ESC
- [ 1 1 ~ is bound to insert the text `Function Key 1'.

--------------------------------------
-
-`accept-line (Newline, Return)'
- Accept the line regardless of where the cursor is. If this line is

-
-Commands For Changing Text
---------------------------
-
-`delete-char (C-d)'
- Delete the character under the cursor. If the cursor is at the
- beginning of the line, and there are no characters in the line, and
- the last character typed was not C-d, then return EOF.
-
-`backward-delete-char (Rubout)'
- Delete the character behind the cursor. A numeric arg says to kill
- the characters instead of deleting them.

-
-`self-insert (a, b, A, 1, !, ...)'
- Insert yourself.
-
-`transpose-chars (C-t)'
- Drag the character before point forward over the character at
- point. Point moves forward as well. If point is at the end of
- the line, then transpose the two characters before point.

-Killing And Yanking
--------------------
-
-`kill-line (C-k)'
- Kill the text from the current cursor position to the end of the
- line.
-
-`backward-kill-line ()'
- Kill backward to the beginning of the line. This is normally
- unbound.
-
-`kill-word (M-d)'
- Kill from the cursor to the end of the current word, or if between
- words, to the end of the next word.
-
-`backward-kill-word (M-DEL)'
- Kill the word behind the cursor.
-

- Do what C-u used to do in Unix line input. We save the killed
- text on the kill-ring, though.
-
-`unix-word-rubout (C-w)'
- Do what C-w used to do in Unix line input. The killed text is
- saved on the kill-ring. This is different than backward-kill-word
- because the word boundaries differ.
-
-`yank (C-y)'
- Yank the top of the kill ring into the buffer at point.
-
-`yank-pop (M-y)'
- Rotate the kill-ring, and yank the new top. You can only do this
- if the prior command is yank or yank-pop.
-
-

-
-Specifying Numeric Arguments
-----------------------------
-
-`digit-argument (M-0, M-1, ... M--)'
- Add this digit to the argument already accumulating, or start a new
- argument. M- starts a negative argument.
-
-`universal-argument ()'
- Do what C-u does in emacs. By default, this is not bound.
-
-

-
-Letting Readline Type For You
------------------------------
-
-`complete (TAB)'
- Attempt to do completion on the text before point. This is
- implementation defined. Generally, if you are typing a filename
- argument, you can do filename completion; if you are typing a
- command, you can do command completion, if you are typing in a
- symbol to GDB, you can do symbol name completion, if you are
- typing in a variable to Bash, you can do variable name
- completion...
-
-`possible-completions (M-?)'
- List the possible completions of the text before point.

-
-Some Miscellaneous Commands
----------------------------
-
-`re-read-init-file (C-x C-r)'
- Read in the contents of your `~/.inputrc' file, and incorporate
- any bindings found there.
-
-`abort (C-g)'
- Stop running the current editing command.
-
-`prefix-meta (ESC)'
- Make the next character that you type be metafied. This is for
- people without a meta key. Typing ESC f is equivalent to typing
- M-f.
-
-`undo (C-_)'
- Incremental undo, separately remembered for each line.
-
-`revert-line (M-r)'
- Undo all changes made to this line. This is like typing the `undo'
- command enough times to get back to the beginning.
-
-
-File: gdb.info, Node: Readline Vi Mode, Prev: Readline Init Syntax, Up: Readline Init File
-
-Readline Vi Mode
-----------------
-
- While the Readline library does not have a full set of Vi editing
-functions, it does contain enough to allow simple editing of the line.
-
- In order to switch interactively between Emacs and Vi editing modes,
-use the command M-C-j (toggle-editing-mode).
-
- When you enter a line in Vi mode, you are already placed in
-`insertion' mode, as if you had typed an `i'. Pressing ESC switches
-you into `edit' mode, where you can edit the text of the line with the
-standard Vi movement keys, move to previous history lines with `k', and
-following lines with `j', and so forth.

-History Interaction
-===================
-
- The History library provides a history expansion feature that is
-similar to the history expansion in Csh. The following text describes
-the sytax that you use to manipulate the history information.
-
- History expansion takes place in two parts. The first is to
-determine which line from the previous history should be used during
-substitution. The second is to select portions of that line for
-inclusion into the current one. The line selected from the previous
-history is called the "event", and the portions of that line that are
-acted upon are called "words". The line is broken into words in the
-same fashion that the Bash shell does, so that several English (or
-Unix) words surrounded by quotes are considered as one word.

-
-Event Designators
------------------
-
- An event designator is a reference to a command line entry in the
-history list.
-
-`!'
- Start a history subsititution, except when followed by a space,
- tab, or the end of the line... = or (.
-
-`!!'
- Refer to the previous command. This is a synonym for `!-1'.
-
-`!n'
- Refer to command line N.
-
-`!-n'
- Refer to the command line N lines back.
-
-`!string'
- Refer to the most recent command starting with STRING.
-
-`!?string'[`?']
- Refer to the most recent command containing STRING.
-
-
-File: gdb.info, Node: Word Designators, Next: Modifiers, Prev: Event Designators, Up: History Interaction
-
-Word Designators
-----------------
-
- A : separates the event specification from the word designator. It
-can be omitted if the word designator begins with a ^, $, * or %.
-Words are numbered from the beginning of the line, with the first word
-being denoted by a 0 (zero).
-
-`0 (zero)'
- The zero'th word. For many applications, this is the command word.
-
-`n'
- The N'th word.
-
-`^'
- The first argument. that is, word 1.
-
-`$'
- The last argument.
-
-`%'
- The word matched by the most recent `?string?' search.
-
-`x-y'
- A range of words; `-Y' Abbreviates `0-Y'.
-
-`*'
- All of the words, excepting the zero'th. This is a synonym for
- `1-$'. It is not an error to use * if there is just one word in
- the event. The empty string is returned in that case.
-
-
-File: gdb.info, Node: Modifiers, Prev: Word Designators, Up: History Interaction
-
-Modifiers
----------
-
- After the optional word designator, you can add a sequence of one or
-more of the following modifiers, each preceded by a :.
-
-`#'
- The entire command line typed so far. This means the current
- command, not the previous command, so it really isn't a word
- designator, and doesn't belong in this section.
-
-`h'
- Remove a trailing pathname component, leaving only the head.
-
-`r'
- Remove a trailing suffix of the form `.'SUFFIX, leaving the
- basename.
-
-`e'
- Remove all but the suffix.
-
-`t'
- Remove all leading pathname components, leaving the tail.
-
-`p'
- Print the new command but do not execute it.

-Formatting Documentation
-************************
-
- The GDB 4 release includes an already-formatted reference card, ready
-for printing with PostScript or GhostScript, in the `gdb' subdirectory
-of the main source directory(1). If you can use PostScript or
-GhostScript with your printer, you can print the reference card
-immediately with `refcard.ps'.
-
- The release also includes the source for the reference card. You
-can format it, using TeX, by typing:
-
- make refcard.dvi
-
- The GDB reference card is designed to print in landscape mode on US
-"letter" size paper; that is, on a sheet 11 inches wide by 8.5 inches
-high. You will need to specify this form of printing as an option to
-your DVI output program.
-
- All the documentation for GDB comes as part of the machine-readable
-distribution. The documentation is written in Texinfo format, which is
-a documentation system that uses a single source file to produce both
-on-line information and a printed manual. You can use one of the Info
-formatting commands to create the on-line version of the documentation
-and TeX (or `texi2roff') to typeset the printed version.
-
- GDB includes an already formatted copy of the on-line Info version of
-this manual in the `gdb' subdirectory. The main Info file is
-`gdb-VERSION-NUMBER/gdb/gdb.info', and it refers to subordinate files
-matching `gdb.info*' in the same directory. If necessary, you can
-print out these files, or read them with any editor; but they are
-easier to read using the `info' subsystem in GNU Emacs or the
-standalone `info' program, available as part of the GNU Texinfo
-distribution.
-
- If you want to format these Info files yourself, you need one of the
-Info formatting programs, such as `texinfo-format-buffer' or `makeinfo'.
-
- If you have `makeinfo' installed, and are in the top level GDB
-source directory (`gdb-4.11', in the case of version 4.11), you can
-make the Info file by typing:
-
- cd gdb
- make gdb.info
-
- If you want to typeset and print copies of this manual, you need TeX,
-a program to print its DVI output files, and `texinfo.tex', the Texinfo
-definitions file.
-
- TeX is a typesetting program; it does not print files directly, but
-produces output files called DVI files. To print a typeset document,
-you need a program to print DVI files. If your system has TeX
-installed, chances are it has such a program. The precise command to
-use depends on your system; `lpr -d' is common; another (for PostScript
-devices) is `dvips'. The DVI print command may require a file name
-without any extension or a `.dvi' extension.
-
- TeX also requires a macro definitions file called `texinfo.tex'.
-This file tells TeX how to typeset a document written in Texinfo
-format. On its own, TeX cannot read, much less typeset a Texinfo file.
-`texinfo.tex' is distributed with GDB and is located in the
-`gdb-VERSION-NUMBER/texinfo' directory.
-
- If you have TeX and a DVI printer program installed, you can typeset
-and print this manual. First switch to the the `gdb' subdirectory of
-the main source directory (for example, to `gdb-4.11/gdb') and then
-type:
-
- make gdb.dvi

-Installing GDB
-**************
-
- GDB comes with a `configure' script that automates the process of
-preparing GDB for installation; you can then use `make' to build the
-`gdb' program.
-
- The GDB distribution includes all the source code you need for GDB in
-a single directory, whose name is usually composed by appending the
-version number to `gdb'.
-
- For example, the GDB version 4.11 distribution is in the `gdb-4.11'
-directory. That directory contains:
-
-`gdb-4.11/configure (and supporting files)'
- script for configuring GDB and all its supporting libraries.
-
-`gdb-4.11/gdb'
- the source specific to GDB itself
-
-`gdb-4.11/bfd'
- source for the Binary File Descriptor library
-
-`gdb-4.11/include'
- GNU include files
-
-`gdb-4.11/libiberty'
- source for the `-liberty' free software library
-
-`gdb-4.11/opcodes'
- source for the library of opcode tables and disassemblers
-
-`gdb-4.11/readline'
- source for the GNU command-line interface
-
-`gdb-4.11/glob'
- source for the GNU filename pattern-matching subroutine
-
-`gdb-4.11/mmalloc'
- source for the GNU memory-mapped malloc package
-
- The simplest way to configure and build GDB is to run `configure'
-from the `gdb-VERSION-NUMBER' source directory, which in this example
-is the `gdb-4.11' directory.
-
- First switch to the `gdb-VERSION-NUMBER' source directory if you are
-not already in it; then run `configure'. Pass the identifier for the
-platform on which GDB will run as an argument.
-
- For example:
-
- cd gdb-4.11
- ./configure HOST
- make
-
-where HOST is an identifier such as `sun4' or `decstation', that
-identifies the platform where GDB will run. (You can often leave off
-HOST; `configure' tries to guess the correct value by examining your
-system.)
-
- Running `configure HOST' and then running `make' builds the `bfd',
-`readline', `mmalloc', and `libiberty' libraries, then `gdb' itself.
-The configured source files, and the binaries, are left in the
-corresponding source directories.
-
- `configure' is a Bourne-shell (`/bin/sh') script; if your system
-does not recognize this automatically when you run a different shell,
-you may need to run `sh' on it explicitly:
-
- sh configure HOST
-
- If you run `configure' from a directory that contains source
-directories for multiple libraries or programs, such as the `gdb-4.11'
-source directory for version 4.11, `configure' creates configuration
-files for every directory level underneath (unless you tell it not to,
-with the `--norecursion' option).
-
- You can run the `configure' script from any of the subordinate
-directories in the GDB distribution if you only want to configure that
-subdirectory, but be sure to specify a path to it.
-
- For example, with version 4.11, type the following to configure only
-the `bfd' subdirectory:
-
- cd gdb-4.11/bfd
- ../configure HOST
-
- You can install `gdb' anywhere; it has no hardwired paths. However,
-you should make sure that the shell on your path (named by the `SHELL'
-environment variable) is publicly readable. Remember that GDB uses the
-shell to start your program--some systems refuse to let GDB debug child
-processes whose programs are not readable.

-Compiling GDB in another directory
-==================================
-
- If you want to run GDB versions for several host or target machines,
-you need a different `gdb' compiled for each combination of host and
-target. `configure' is designed to make this easy by allowing you to
-generate each configuration in a separate subdirectory, rather than in
-the source directory. If your `make' program handles the `VPATH'
-feature (GNU `make' does), running `make' in each of these directories
-builds the `gdb' program specified there.
-
- To build `gdb' in a separate directory, run `configure' with the
-`--srcdir' option to specify where to find the source. (You also need
-to specify a path to find `configure' itself from your working
-directory. If the path to `configure' would be the same as the
-argument to `--srcdir', you can leave out the `--srcdir' option; it
-will be assumed.)
-
- For example, with version 4.11, you can build GDB in a separate
-directory for a Sun 4 like this:
-
- cd gdb-4.11
- mkdir ../gdb-sun4
- cd ../gdb-sun4
- ../gdb-4.11/configure sun4
- make
-
- When `configure' builds a configuration using a remote source
-directory, it creates a tree for the binaries with the same structure
-(and using the same names) as the tree under the source directory. In
-the example, you'd find the Sun 4 library `libiberty.a' in the
-directory `gdb-sun4/libiberty', and GDB itself in `gdb-sun4/gdb'.
-
- One popular reason to build several GDB configurations in separate
-directories is to configure GDB for cross-compiling (where GDB runs on
-one machine--the host--while debugging programs that run on another
-machine--the target). You specify a cross-debugging target by giving
-the `--target=TARGET' option to `configure'.
-
- When you run `make' to build a program or library, you must run it
-in a configured directory--whatever directory you were in when you
-called `configure' (or one of its subdirectories).
-
- The `Makefile' that `configure' generates in each source directory
-also runs recursively. If you type `make' in a source directory such
-as `gdb-4.11' (or in a separate configured directory configured with
-`--srcdir=PATH/gdb-4.11'), you will build all the required libraries,
-and then build GDB.
-
- When you have multiple hosts or targets configured in separate
-directories, you can run `make' on them in parallel (for example, if
-they are NFS-mounted on each of the hosts); they will not interfere
-with each other.
-
-
-File: gdb.info, Node: Config Names, Next: configure Options, Prev: Separate Objdir, Up: Installing GDB
-
-Specifying names for hosts and targets
-======================================
-
- The specifications used for hosts and targets in the `configure'
-script are based on a three-part naming scheme, but some short
-predefined aliases are also supported. The full naming scheme encodes
-three pieces of information in the following pattern:
-
- ARCHITECTURE-VENDOR-OS
-
- For example, you can use the alias `sun4' as a HOST argument, or as
-the value for TARGET in a `--target=TARGET' option. The equivalent
-full name is `sparc-sun-sunos4'.
-
- The `configure' script accompanying GDB does not provide any query
-facility to list all supported host and target names or aliases.
-`configure' calls the Bourne shell script `config.sub' to map
-abbreviations to full names; you can read the script, if you wish, or
-you can use it to test your guesses on abbreviations--for example:
-
- % sh config.sub sun4
- sparc-sun-sunos4.1.1
- % sh config.sub sun3
- m68k-sun-sunos4.1.1
- % sh config.sub decstation
- mips-dec-ultrix4.2
- % sh config.sub hp300bsd
- m68k-hp-bsd
- % sh config.sub i386v
- i386-unknown-sysv
- % sh config.sub i786v
- Invalid configuration `i786v': machine `i786v' not recognized
-
-`config.sub' is also distributed in the GDB source directory
-(`gdb-4.11', for version 4.11).

-
-`configure' options
-===================
-
- Here is a summary of the `configure' options and arguments that are
-most often useful for building GDB. `configure' also has several other
-options not listed here. *note : (configure.info)What Configure Does,
-for a full explanation of `configure'.
-
- configure [--help]
- [--prefix=DIR]
- [--srcdir=PATH]
- [--norecursion] [--rm]
- [--target=TARGET] HOST
-
-You may introduce options with a single `-' rather than `--' if you
-prefer; but you may abbreviate option names if you use `--'.
-
-`--help'
- Display a quick summary of how to invoke `configure'.
-
-`-prefix=DIR'
- Configure the source to install programs and files under directory
- `DIR'.
-
-`--srcdir=PATH'
- *Warning: using this option requires GNU `make', or another `make'
- that implements the `VPATH' feature.*
- Use this option to make configurations in directories separate
- from the GDB source directories. Among other things, you can use
- this to build (or maintain) several configurations simultaneously,
- in separate directories. `configure' writes configuration
- specific files in the current directory, but arranges for them to
- use the source in the directory PATH. `configure' will create
- directories under the working directory in parallel to the source
- directories below PATH.
-
-`--norecursion'
- Configure only the directory level where `configure' is executed;
- do not propagate configuration to subdirectories.
-
-`--rm'
- *Remove* files otherwise built during configuration.
-
-`--target=TARGET'
- Configure GDB for cross-debugging programs running on the specified
- TARGET. Without this option, GDB is configured to debug programs
- that run on the same machine (HOST) as GDB itself.
-
- There is no convenient way to generate a list of all available
- targets.
-
-`HOST ...'
- Configure GDB to run on the specified HOST.
-
- There is no convenient way to generate a list of all available
- hosts.
-
-`configure' accepts other options, for compatibility with configuring
-other GNU tools recursively; but these are the only options that affect
-GDB or its supporting libraries.

-@end deftypefun
-
-
-@heading callbacks
-
-One idiom used in several places deserves mention.
-At times, it makes sense for libgdb functions to
-invoke functions provided by the libgdb client.
-Where this is the case, callback structures are used
-to refer to client functions. For example, here
-are the declarations for a callback to which libgdb
-will pass an integer and a character pointer.
-
-@example
-struct a_gdb_cback;
-typedef void (*a_gdb_cback_fn) (struct a_gdb_cback *,
- int, char *);
-@end example
-
-Suppose the client wants the callback to be implemented
-by @code{foo} which we will assume takes not only the integer
-and character pointer, but also a floating point number.
-The client could use these declarations:
-
-@example
-struct my_cback
-@{
- struct a_gdb_cback gdb_cback; /* must be first */
- float magic_number;
-@};
-
-void
-foo_helper (struct a_gdb_cback * callback, int i, char * cp)
-@{
- foo ( ((struct my_cback *)callback)->magic_number, i, c);
-@}
-
-struct my_cback
-@{
- foo_helper,
- 1079252848.8
-@} the_cback;
-@end example
-
-
-@subheading stream callbacks
-
-A common kind of callback takes just a character pointer,
-presumed to point to part or all of an informational
-message.
-
-@example
-struct gdb_stream_cback;
-typedef void (*gdb_stream_cback_fn) (struct gdb_stream_cback *,
- char *);
-@end example
-
-
-@subheading integer callbacks
-
-Another common kind of callback takes just an integer.
-
-@example
-struct gdb_int_cback;
-typedef void (*gdb_int_cback_fn) (struct gdb_int_cback *, int);
-@end example

-
-@deftypefun gdb_error_t gdb_use_file (char * @var{filename})
-Arrange to read both executable code and symbol table information
-from FILENAME.
-
-This is exactly equivalent to a sequence of two calls:
-@example
- gdb_use_exec_file (filename);
- gdb_use_symbol_file (filename);

-@end deftypefun
-
-
-@deftypefun gdb_error_t gdb_use_core (char * @var{filename})
-Specify the whereabouts of a core dump file to be used as the
-"contents of memory". Traditionally, core files contain only some
-parts of the address space of the process that generated them; GDB
-can access the executable file itself for other parts.
-
-If @var{filename} is @code{NULL}, no core file is used.@*

-
-@deftypefun gdb_error_t gdb_use_symbol_file (char * @var{filename})
-Arrange to read symbol table information from `filename'.
-
-This is the same as:
-
- gdb_symbol_file_add (filename, 1, (CORE_ADDR)0, 1, 0, 0);
-
-See @code{gdb_symbol_file_add} for finer control over the symbol

-
-The arguments are:
-@itemize @minus
-@item struct gdb_stream_cback * @var{info_out}
-
-Callback to handle informational output.
-
-@item char * @var{name}
-
-If not 0, verbose output will occur.
-
-@item int @var{be_verbose}
-
-Regulates the amount of informational output produced.
-
-@item CORE_ADDR @var{text_addr}
-
-is the address at which the named file is presumed to have
-been loaded.
-
-@item int @var{replace}@*

-
-@code{struct symtab_and_line} is used to refer to a particular line
-of source code. It is used to locate breakpoints in the source
-code and the executable.
-
-@code{line} starts at 1 and proceeds through symtab->nlines.
-0 is never a valid line number; it is used to indicate
-that line number information is not available.
-@end deftp

-
-@deftypefun {struct symtab_and_line} gdb_find_pc_line (CORE_ADDR @var{pc}, int @var{notcurrent})
-Find the source file and line number for a given @var{pc} value.
-Return a structure containing a symtab pointer, a line number,
-and a pc range for the entire source line.
-The value's @code{.pc} field is NOT the specified @var{pc}.
-@var{notcurrent} nonzero means, if specified pc is on a line boundary,

-(find_pc_line)
-@end deftypefun
-
-
-@deftypefun gdb_error_t gdb_find_line (struct symtab_and_line * @var{out}, struct symtab *, int)
-Create a symtab_and_line for a given symtab and line number.

-
-
-@deftypefun {struct symtabs_and_lines} gdb_decode_line (@var{argptr}, @var{firstln}, @var{default_symtab}, @var{default_line}, @var{canonical})
-@example
- char ** argptr;
- int funfirstline;
- struct symtab * default_symtab;
- int default_line;
- char *** canonical;
-@end example
- Parse a string that specifies a line number in GDB syntax.
- @var{argptr} will be advanced over the characters actually parsed.
-
- The string can be:
-
- LINENUM -- that line number in current file. PC returned is 0.
- FILE:LINENUM -- that line in that file. PC returned is 0.
- FUNCTION -- line number of openbrace of that function.
- PC returned is the start of the function.
- VARIABLE -- line number of definition of that variable.
- PC returned is 0.
- FILE:FUNCTION -- likewise, but prefer functions in that file.
- *EXPR -- line in which address EXPR appears.
-
- FUNCTION may be an undebuggable function found in minimal symbol
- table.
-
- If the argument FUNFIRSTLINE is nonzero, we want the first line
- of real code inside a function when a function is specified.
-
- DEFAULT_SYMTAB specifies the file to use if none is specified.
- It defaults to current_source_symtab.
-
- DEFAULT_LINE specifies the line number to use for relative line
- numbers (that start with signs). Defaults to current_source_line.
- If CANONICAL is non-NULL, store an array of strings containing the
- canonical line specs there if necessary. Currently overloaded
- member functions and line numbers or static functions without a
- filename yield a canonical line spec. The array and the line spec
- strings are allocated on the heap, it is the callers responsibility

-@end example
-Print a description of a type @var{type} in the form of a declaration of a
-variable named @var{varstring}. (@var{varstring} is demangled if necessary.)
-Output goes to @var{stream_cback}.
-
-If @var{show} is positive, we show the contents of the outermost level
-of structure even if there is a type name that could be used instead.
-If @var{show} is negative, we never show the details of elements' types.

-% Modifications made in order to handle different papersizes correctly.
-% You only have to set the total width and height of the paper, the
-% horizontal and vertical margin space measured from *paper edge*
-% and the interline and interspec spacing.
-% In order to support a new papersize, you have to fiddle with the
-% latter four dimensions. Just try out a few values.
-% All other values will be computed at process time so it should be
-% quite easy to support different paper sizes - only four values to
-% guess :-)
-%
-% To find the configuration places, just search for the string
-% "CONFIGURATION".

-% Uncomment the following `magnification' command if you want to print
-% out in a larger font. Caution! You may need larger paper. You had
-% best avoid using 3-column output if you try this. See the ``Three
-% column format'' section below if you want to print in three column
-% format.

-% NOTE ON INTENTIONAL OMISSIONS: This reference card includes most GDB
-% commands, but due to space constraints there are some things I chose
-% to omit. In general, not all synonyms for commands are covered, nor
-% all variations of a command.
-% The GDB-under-Emacs section omits gdb-mode functions without default
-% keybindings. GDB startup options are not described.
-% set print sevenbit-strings, set symbol-reloading omitted.
-% printsyms, printpsyms, omitted since they're for GDB maintenance primarily
-% share omitted due to obsolescence
-% set check range/type omitted at least til code is in GDB.

-LOCAL FUNCTION
-
- locate_base -- locate the base address of dynamic linker structs
-
-SYNOPSIS
-
- CORE_ADDR locate_base (void)
-
-DESCRIPTION
-
- For both the SunOS and SVR4 shared library implementations, if the
- inferior executable has been linked dynamically, there is a single
- address somewhere in the inferior's data space which is the key to
- locating all of the dynamic linker's runtime structures. This
- address is the value of the symbol defined by the macro DEBUG_BASE.
- The job of this function is to find and return that address, or to
- return 0 if there is no such address (the executable is statically
- linked for example).
-
- For SunOS, the job is almost trivial, since the dynamic linker and
- all of it's structures are statically linked to the executable at
- link time. Thus the symbol for the address we are looking for has
- already been added to the minimal symbol table for the executable's
- objfile at the time the symbol file's symbols were read, and all we
- have to do is look it up there. Note that we explicitly do NOT want
- to find the copies in the shared library.
-
- The SVR4 version is much more complicated because the dynamic linker
- and it's structures are located in the shared C library, which gets
- run as the executable's "interpreter" by the kernel. We have to go
- to a lot more work to discover the address of DEBUG_BASE. Because
- of this complexity, we cache the value we find and return that value
- on subsequent invocations. Note there is no copy in the executable
- symbol tables.
-
- Note that we can assume nothing about the process state at the time
- we need to find this address. We may be stopped on the first instruc-
- tion of the interpreter (C shared library), the first instruction of
- the executable itself, or somewhere else entirely (if we attached
- to the process for example).

-
- enable_break -- arrange for dynamic linker to hit breakpoint
-
-SYNOPSIS
-
- int enable_break (void)
-
-DESCRIPTION
-
- Both the SunOS and the SVR4 dynamic linkers have, as part of their
- debugger interface, support for arranging for the inferior to hit
- a breakpoint after mapping in the shared libraries. This function
- enables that breakpoint.
-
- For SunOS, there is a special flag location (in_debugger) which we
- set to 1. When the dynamic linker sees this flag set, it will set
- a breakpoint at a location known only to itself, after saving the
- original contents of that place and the breakpoint address itself,
- in it's own internal structures. When we resume the inferior, it
- will eventually take a SIGTRAP when it runs into the breakpoint.
- We handle this (in a different place) by restoring the contents of
- the breakpointed location (which is only known after it stops),
- chasing around to locate the shared libraries that have been
- loaded, then resuming.
-
- For SVR4, the debugger interface structure contains a member (r_brk)
- which is statically initialized at the time the shared library is
- built, to the offset of a function (_r_debug_state) which is guaran-
- teed to be called once before mapping in a library, and again when
- the mapping is complete. At the time we are examining this member,
- it contains only the unrelocated offset of the function, so we have
- to do our own relocation. Later, when the dynamic linker actually
- runs, it relocates r_brk to be the actual address of _r_debug_state().
-
- The debugger interface structure also contains an enumeration which
- is set to either RT_ADD or RT_DELETE prior to changing the mapping,
- depending upon whether or not the library is being mapped or unmapped,
- and then set to RT_CONSISTENT after the library is mapped/unmapped.

-GLOBAL FUNCTION
-
- solib_create_inferior_hook -- shared library startup support
-
-SYNOPSIS
-
- void solib_create_inferior_hook()
-
-DESCRIPTION
-
- When gdb starts up the inferior, it nurses it along (through the
- shell) until it is ready to execute it's first instruction. At this
- point, this function gets called via expansion of the macro
- SOLIB_CREATE_INFERIOR_HOOK.
-
- For SunOS executables, this first instruction is typically the
- one at "_start", or a similar text label, regardless of whether
- the executable is statically or dynamically linked. The runtime
- startup code takes care of dynamically linking in any shared
- libraries, once gdb allows the inferior to continue.
-
- For SVR4 executables, this first instruction is either the first
- instruction in the dynamic linker (for dynamically linked
- executables) or the instruction at "start" for statically linked
- executables. For dynamically linked executables, the system
- first exec's /lib/libc.so.N, which contains the dynamic linker,
- and starts it running. The dynamic linker maps in any needed
- shared libraries, maps in the actual user executable, and then
- jumps to "start" in the user executable.
-
- For both SunOS shared libraries, and SVR4 shared libraries, we
- can arrange to cooperate with the dynamic linker to discover the
- names of shared libraries that are dynamically linked, and the
- base addresses to which they are linked.
-
- This function is responsible for discovering those names and
- addresses, and saving sufficient information about them to allow
- their symbols to be read at a later time.
-
-FIXME
-
- Between enable_break() and disable_break(), this code does not
- properly handle hitting breakpoints which the user might have
- set in the startup code or in the dynamic linker itself. Proper
- handling will probably have to wait until the implementation is
- changed to use the "breakpoint handler function" method.
-
- Also, what if child has exit()ed? Must exit loop somehow.

-/* Notes on the algorithm used in wait_for_inferior to determine if we
- just did a subroutine call when stepping. We have the following
- information at that point:
-
- Current and previous (just before this step) pc.
- Current and previous sp.
- Current and previous start of current function.
-
- If the start's of the functions don't match, then
-
- a) We did a subroutine call.
-
- In this case, the pc will be at the beginning of a function.
-
- b) We did a subroutine return.
-
- Otherwise.
-
- c) We did a longjmp.
-
- If we did a longjump, we were doing "nexti", since a next would
- have attempted to skip over the assembly language routine in which
- the longjmp is coded and would have simply been the equivalent of a
- continue. I consider this ok behaivior. We'd like one of two
- things to happen if we are doing a nexti through the longjmp()
- routine: 1) It behaves as a stepi, or 2) It acts like a continue as
- above. Given that this is a special case, and that anybody who
- thinks that the concept of sub calls is meaningful in the context
- of a longjmp, I'll take either one. Let's see what happens.
-
- Acts like a subroutine return. I can handle that with no problem
- at all.
-
- -->So: If the current and previous beginnings of the current
- function don't match, *and* the pc is at the start of a function,
- we've done a subroutine call. If the pc is not at the start of a
- function, we *didn't* do a subroutine call.
-
- -->If the beginnings of the current and previous function do match,
- either:
-
- a) We just did a recursive call.
-
- In this case, we would be at the very beginning of a
- function and 1) it will have a prologue (don't jump to
- before prologue, or 2) (we assume here that it doesn't have
- a prologue) there will have been a change in the stack
- pointer over the last instruction. (Ie. it's got to put
- the saved pc somewhere. The stack is the usual place. In
- a recursive call a register is only an option if there's a
- prologue to do something with it. This is even true on
- register window machines; the prologue sets up the new
- window. It might not be true on a register window machine
- where the call instruction moved the register window
- itself. Hmmm. One would hope that the stack pointer would
- also change. If it doesn't, somebody send me a note, and
- I'll work out a more general theory.
- randy@wheaties.ai.mit.edu). This is true (albeit slipperly
- so) on all machines I'm aware of:
-
- m68k: Call changes stack pointer. Regular jumps don't.
-
- sparc: Recursive calls must have frames and therefor,
- prologues.
-
- vax: All calls have frames and hence change the
- stack pointer.
-
- b) We did a return from a recursive call. I don't see that we
- have either the ability or the need to distinguish this
- from an ordinary jump. The stack frame will be printed
- when and if the frame pointer changes; if we are in a
- function without a frame pointer, it's the users own
- lookout.
-
- c) We did a jump within a function. We assume that this is
- true if we didn't do a recursive call.
-
- d) We are in no-man's land ("I see no symbols here"). We
- don't worry about this; it will make calls look like simple
- jumps (and the stack frames will be printed when the frame
- pointer moves), which is a reasonably non-violent response.
-
-#if 0
- We skip this; it causes more problems than it's worth.
-#ifdef SUN4_COMPILER_FEATURE
- We do a special ifdef for the sun 4, forcing it to single step
- into calls which don't have prologues. This means that we can't
- nexti over leaf nodes, we can probably next over them (since they
- won't have debugging symbols, usually), and we can next out of
- functions returning structures (with a "call .stret4" at the end).

-/* Summary:
-
-All the apparent functions defined here are macros. The idea
-is that you would use these pre-tested macros to solve a
-very specific set of problems, and they would run fast.
-Caution: no side-effects in arguments please!! They may be
-evaluated MANY times!!
-
-These macros operate a stack of objects. Each object starts life
-small, and may grow to maturity. (Consider building a word syllable
-by syllable.) An object can move while it is growing. Once it has
-been "finished" it never changes address again. So the "top of the
-stack" is typically an immature growing object, while the rest of the
-stack is of mature, fixed size and fixed address objects.
-
-These routines grab large chunks of memory, using a function you
-supply, called `obstack_chunk_alloc'. On occasion, they free chunks,
-by calling `obstack_chunk_free'. You must define them and declare
-them before using any obstack macros.
-
-Each independent stack is represented by a `struct obstack'.
-Each of the obstack macros expects a pointer to such a structure
-as the first argument.
-
-One motivation for this package is the problem of growing char strings
-in symbol tables. Unless you are "facist pig with a read-only mind"
-[Gosper's immortal quote from HAKMEM item 154, out of context] you
-would not like to put any arbitrary upper limit on the length of your
-symbols.
-
-In practice this often means you will build many short symbols and a
-few long symbols. At the time you are reading a symbol you don't know
-how long it is. One traditional method is to read a symbol into a
-buffer, realloc()ating the buffer every time you try to read a symbol
-that is longer than the buffer. This is beaut, but you still will
-want to copy the symbol from the buffer to a more permanent
-symbol-table entry say about half the time.
-
-With obstacks, you can work differently. Use one obstack for all symbol
-names. As you read a symbol, grow the name in the obstack gradually.
-When the name is complete, finalize it. Then, if the symbol exists already,
-free the newly read name.
-
-The way we do this is to take a large chunk, allocating memory from
-low addresses. When you want to build a aymbol in the chunk you just
-add chars above the current "high water mark" in the chunk. When you
-have finished adding chars, because you got to the end of the symbol,
-you know how long the chars are, and you can create a new object.
-Mostly the chars will not burst over the highest address of the chunk,
-because you would typically expect a chunk to be (say) 100 times as
-long as an average object.
-
-In case that isn't clear, when we have enough chars to make up
-the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
-so we just point to it where it lies. No moving of chars is
-needed and this is the second win: potentially long strings need
-never be explicitly shuffled. Once an object is formed, it does not
-change its address during its lifetime.
-
-When the chars burst over a chunk boundary, we allocate a larger
-chunk, and then copy the partly formed object from the end of the old
-chunk to the beggining of the new larger chunk. We then carry on
-accreting characters to the end of the object as we normaly would.
-
-A special macro is provided to add a single char at a time to a
-growing object. This allows the use of register variables, which
-break the ordinary 'growth' macro.
-
-Summary:
- We allocate large chunks.
- We carve out one object at a time from the current chunk.
- Once carved, an object never moves.
- We are free to append data of any size to the currently
- growing object.
- Exactly one object is growing in an obstack at any one time.
- You can run one obstack per control block.
- You may have as many control blocks as you dare.
- Because of the way we do it, you can `unwind' a obstack
- back to a previous state. (You may remove objects much
- as you would with a stack.)

-
- rl_insert (). Read type-ahead buffer for additional
- keys that are bound to rl_insert, and insert them
- all at once. Make insertion of single keys given
- with an argument much more efficient.
-
-Tue Aug 8 18:13:57 1989 Brian Fox (bfox at aurel)
-
- * readline.c: Changed handling of EOF. readline () returns
- (char *)EOF or consed string. The EOF character is read from the
- tty, or if the tty doesn't have one, defaults to C-d.
-
- * readline.c: Added support for event driven programs.

- If non-null, this contains the address of a function to call if
- the standard meaning for expanding a tilde fails. The function is
- called with the text sans tilde (as in "foo"), and returns a
- malloc()'ed string which is the expansion, or a NULL pointer if
- there is no expansion.
-
- * readline.h - new file chardefs.h
- Separates things that only readline.c needs from the standard
- header file publishing interesting things about readline.
-
- * readline.c:
- readline_default_bindings () now looks at terminal chararacters
- and binds those as well.

-/* Format of GDB symbol table data.
- There is one symbol segment for each source file or
- independant compilation. These segments are simply concatenated
- to form the GDB symbol table. A zero word where the beginning
- of a segment is expected indicates there are no more segments.
-
-Format of a symbol segment:
-
- The symbol segment begins with a word containing 1
- if it is in the format described here. Other formats may
- be designed, with other code numbers.
-
- The segment contains many objects which point at each other.
- The pointers are offsets in bytes from the beginning of the segment.
- Thus, each segment can be loaded into core and its pointers relocated
- to make valid in-core pointers.
-
- All the data objects in the segment can be found indirectly from
- one of them, the root object, of type `struct symbol_root'.
- It appears at the beginning of the segment.
-
- The total size of the segment, in bytes, appears as the `length'
- field of this object. This size includes the size of the
- root object.
-
- All the object data types are defined here to contain pointer types
- appropriate for in-core use on a relocated symbol segment.
- Casts to and from type int are required for working with
- unrelocated symbol segments such as are found in the file.
-
- The ldsymaddr word is filled in by the loader to contain
- the offset (in bytes) within the ld symbol table
- of the first nonglobal symbol from this compilation.
- This makes it possible to match those symbols
- (which contain line number information) reliably with
- the segment they go with.
-
- Core addresses within the program that appear in the symbol segment
- are not relocated by the loader. They are inserted by the assembler
- and apply to addresses as output by the assembler, so GDB must
- relocate them when it loads the symbol segment. It gets the information
- on how to relocate from the textrel, datarel, bssrel, databeg and bssbeg
- words of the root object.
-
- The words textrel, datarel and bssrel
- are filled in by ld with the amounts to relocate within-the-file
- text, data and bss addresses by; databeg and bssbeg can be
- used to tell which kind of relocation an address needs. */

- less than twice the size of the format string. This is a very
- arbitrary restriction, but it is an internal restriction, so I'll
- put it in. This means that the %s format specifier is almost
- useless; unless the caller can GUARANTEE that the string is short
- enough, fputs_filtered should be used instead.
-
- Note also that a longjmp to top level may occur in this routine
- (since prompt_for_continue may do so) so this routine should not be
- called when cleanups are not in place. */

- so that eventually all the non-options are at the end. This allows options
- to be given in any order, even with programs that were not written to
- expect this.
-
- RETURN_IN_ORDER is an option available to programs that were written
- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only

-/* Scan elements of ARGV (whose length is ARGC) for option characters
- given in OPTSTRING.
-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns `EOF'.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce
- long-named options. */

-.SH NAME
-pr \- convert text files for printing
-.SH SYNOPSIS
-.B pr
-[+PAGE] [\-COLUMN] [\-abcdfFmrtv] [\-e[in-tab-char[in-tab-width]]]
-[\-h header] [\-i[out-tab-char[out-tab-width]]] [\-l page-length]
-[\-n[number-separator[digits]]] [\-o left-margin]
-[\-s[column-separator]] [\-w page-width] [\-\-help] [\-\-version] [file...]
-.SH DESCRIPTION
-This manual page
-documents the GNU version of
-.BR pr .
-.B pr
-prints on the standard output a paginated and optionally multicolumn
-copy of the text files given on the command line, or of the standard
-input if no files are given or when the file name `\-' is encountered.
-Form feeds in the input cause page breaks in the output.
-.SS OPTIONS
-.TP
-.I \+PAGE
-Begin printing with page \fIPAGE\fP.
-.TP
-.I \-COLUMN
-Produce \fICOLUMN\fP-column output and print columns down. The column
-width is automatically decreased as \fICOLUMN\fP increases; unless you
-use the \fI\-w\fP option to increase the page width as well, this
-option might cause some columns to be truncated.
-.TP
-.I \-a
-Print columns across rather than down.
-.TP
-.I \-b
-Balance columns on the last page.
-.TP
-.I \-c
-Print control characters using hat notation (e.g., `^G'); print other
-unprintable characters in octal backslash notation.
-.TP
-.I \-d
-Double space the output.
-.TP
-.I "\-e[in-tab-char[in-tab-width]]"
-Expand tabs to spaces on input. Optional argument \fIin-tab-char\fP
-is the input tab character, default tab. Optional argument
-\fIin-tab-width\fP is the input tab character's width, default 8.
-.TP
-.I "\-F, \-f"
-Use a formfeed instead of newlines to separate output pages.
-.TP
-.I "\-h header"
-Replace the filename in the header with the string \fIheader\fP.
-.TP
-.I "\-\-help"
-Print a usage message and exit with a non-zero status.

- pr -n -3 -s: /usr/dict/words

- pr -6 -a -n -o5 /usr/dict/words
-
- Ideas:
-
- Keep a things_to_do list of functions to call when we know we have
- something to print. Cleaner than current series of checks.
-
- Improve the printing of control prefixes.
-
-
- Options:
-
- +PAGE Begin output at page PAGE of the output.
-
- -COLUMN Produce output that is COLUMN columns wide and print
- columns down.
-
- -a Print columns across rather than down. The input
- one
- two
- three
- four
- will be printed as
- one two three
- four
-
- -b Balance columns on the last page.
-
- -c Print unprintable characters as control prefixes.
- Control-g is printed as ^G.
-
- -d Double space the output.
-
- -e[c[k]] Expand tabs to spaces on input. Optional argument C
- is the input tab character. (Default is `\t'.) Optional
- argument K is the input tab character's width. (Default is 8.)
-
- -F
- -f Use formfeeds instead of newlines to separate pages.
-
- -h header Replace the filename in the header with the string HEADER.
-
- -i[c[k]] Replace spaces with tabs on output. Optional argument
- C is the output tab character. (Default is `\t'.) Optional
- argument K is the output tab character's width. (Default
- is 8.)
-
- -l lines Set the page length to LINES. Default is 66.
-
- -m Print files in parallel.
-
- -n[c[k]] Precede each column with a line number.
- (With parallel files, precede each line with a line
- number.) Optional argument C is the character to print
- after each number. (Default `\t'.) Optional argument
- K is the number of digits per line number. (Default 5.)
-
- -o offset Offset each line with a margin OFFSET spaces wide.
- Total page width is the size of this offset plus the
- width set with `-w'.
-
- -r Ignore files that can't be opened.
-
- -s[c] Separate each line with a character. Optional argument C is
- the character to be used. Default is `\t'.
-
- -t Do not print headers or footers.
-
- -v Print unprintable characters as escape sequences.
- Control-G becomes \007.
-
- -w width Set the page width to WIDTH characters. */

-Overview
-********
-
- This manual documents `send-pr', version 3.2, which uses electronic
-mail to submit support questions and problem reports to a central
-Support Site. No body of work is perfect, and support organizations
-understand this; `send-pr' is designed to allow users who have problems
-to submit reports of these problems to sites responsible for supporting
-the products in question, in a defined form which can be read by an
-electronically managed database.
-
- `send-pr' is part of a suite of programs known collectively as
-GNATS, the GNU Problem Report Management System. GNATS consists of
-several programs which, used in concert, formulate and partially
-administer a database of "Problem Reports", or "PRs", at a central
-Support Site. A PR goes through several states in its lifetime; GNATS
-tracks the PR and all information associated with it through each state
-and finally acts as an archive for PRs which have been "closed".
-
- Because `send-pr' exists as a shell (`/bin/sh') script and as an
-Elisp file for use with GNU Emacs, it can be used from any machine on
-your network which can run a shell script and/or Emacs.
-
- In general, you can use any editor and mailer to submit valid Problem
-Reports, as long as the format required by GNATS is preserved.
-`send-pr' automates the process, however, and ensures that certain
-fields necessary for automatic processing are present. `send-pr' is
-strongly recommended for all initial problem-oriented correspondence
-with your Support Site. The organization you submit Problem Reports to
-supplies an address to which further information can be sent; the person
-responsible for the category of the problem you report contacts you
-directly.

-Details about send-pr and GNATS
-*******************************
-
- A "Problem Report" is a message that describes a problem you are
-having with a body of work. `send-pr' organizes this message into a
-form which can be understood and automatically processed by GNATS, the
-GNU Problem Report Management System. A Problem Report is organized
-into "fields" which contain data describing you, your organization, and
-the problem you are announcing (*note Problem Report format: Fields.).
-Problem Reports go through several defined states in their lifetimes,
-from "open" to "closed" (*note States of Problem Reports: States.).

-
-States of Problem Reports
-=========================
-
- Each PR goes through a defined series of states between origination
-and closure. The originator of a PR receives notification
-automatically of any state changes.
-
-"open"
- The initial state of a Problem Report. This means the PR has been
- filed and the responsible person(s) notified.
-
-"analyzed"
- The responsible person has analyzed the problem. The analysis
- should contain a preliminary evaluation of the problem and an
- estimate of the amount of time and resources necessary to solve
- the problem. It should also suggest possible workarounds.
-
-"feedback"
- The problem has been solved, and the originator has been given a
- patch or other fix. The PR remains in this state until the
- originator acknowledges that the solution works.
-
-"closed"
- A Problem Report is closed ("the bug stops here") only when any
- changes have been integrated, documented, and tested, and the
- submitter has confirmed the solution.
-
-"suspended"
- Work on the problem has been postponed. This happens if a timely
- solution is not possible or is not cost-effective at the present
- time. The PR continues to exist, though a solution is not being
- actively sought. If the problem cannot be solved at all, it
- should be closed rather than suspended.

-
-Problem Report format
-=====================
-
- The format of a PR is designed to reflect the nature of GNATS as a
-database. Information is arranged into "fields", and kept in
-individual records (Problem Reports).
-
- Problem Report fields are denoted by a keyword which begins with `>'
-and ends with `:', as in `>Confidential:'. Fields belong to one of
-three data types:
-
-ENUMERATED
- One of a specific set of values, which vary according to the
- field. The value for each keyword must be on the same line as the
- keyword. These values are not configurable (yet).
-
- For each ENUMERATED keyword, the possible choices are listed in the
- `send-pr' template as a comment. The following fields are
- ENUMERATED format; see the descriptions of fields below for
- explanations of each field in detail:
-
- >Confidential: >Severity: >Priority:
- >Class: >State: >Number:
-
-TEXT
- One single line of text which must begin and end on the same line
- (i.e., before a newline) as the keyword. See the descriptions of
- fields below for explanations of each field in detail. The
- following fields are TEXT format:
-
- >Submitter-Id: >Originator: >Synopsis:
- >Category: >Release: >Responsible:
- >Arrival-Date:
-
-MULTITEXT
- Text of any length may occur in this field. MULTITEXT may span
- multiple lines and may also include blank lines. A MULTITEXT field
- ends only when another keyword appears. See the descriptions of
- fields below for explanations of each field in detail.
-
- The following fields are MULTITEXT format:
-
- >Organization: >Environment: >Description:
- >How-To-Repeat: >Fix: >Audit-Trail:
- >Unformatted:
-
- A Problem Report contains two different types of fields: "Mail
-Header" fields, which are used by the mail handler for delivery, and
-"Problem Report" fields, which contain information relevant to the
-Problem Report and its submitter. A Problem Report is essentially a
-specially formatted electronic mail message.
-
- The following is an example Problem Report. Mail headers are at the
-top, followed by GNATS fields, which begin with `>' and end with `:'.
-The `Subject:' line in the mail header and the `>Synopsis:' field are
-usually duplicates of each other.

-Mail header fields
-------------------
-
- A Problem Report may contain any mail header field described in the
-Internet standard RFC-822. However, only the fields which identify the
-sender and the subject are required by `send-pr':
-
-`To:'
- The preconfigured mail address for the Support Site where the PR
- is to be sent, automatically supplied by `send-pr'.
-
-`Subject:'
- A terse description of the problem. This field normally contains
- the same information as the `>Synopsis:' field.
-
-`From:'
- Usually supplied automatically by the originator's mailer; should
- contain the originator's electronic mail address.
-
-`Reply-To:'
- A return address to which electronic replies can be sent; in most
- cases, the same address as the `From:' field.

-Problem Report fields
----------------------
-
-Field descriptions
-------------------
-
- The following fields are present whenever a PR is submitted via the
-program `send-pr'. GNATS adds additional fields when the PR arrives at
-the Support Site; explanations of these follow this list.
-
-`>Submitter-Id:'
- (TEXT) A unique identification code assigned by the Support Site.
- It is used to identify all Problem Reports coming from a particular
- site. (Submitters without a value for this field can invoke
- `send-pr' with the `--request-id' option to apply for one from the
- support organization. Problem Reports from those not affiliated
- with the support organization should use the default value of `net'
- for this field.)
-
-`>Originator:'
- (TEXT) Originator's real name. The default is the value of the
- originator's environment variable `NAME'.
-
-`>Organization:'
- (MULTITEXT) The originator's organization. The default value is
- set with the variable `DEFAULT_ORGANIZATION' in the `send-pr'
- shell script.
-
-`>Confidential:'
- (ENUMERATED) Use of this field depends on the originator's
- relationship with the support organization; contractual agreements
- often have provisions for preserving confidentiality. Conversely,
- a lack of a contract often means that any data provided will not
- be considered confidential. Submitters should be advised to
- contact the support organization directly if this is an issue.
-
- If the originator's relationship to the support organization
- provides for confidentiality, then if the value of this field is
- `yes' the support organization treats the PR as confidential; any
- code samples provided are not made publicly available (e.g., in
- regression test suites). The default value is `yes'.
-
-`>Synopsis:'
- (TEXT) One-line summary of the problem. `send-pr' copies this
- information to the `Subject:' line when you submit a Problem
- Report.
-
-`>Severity:'
- (ENUMERATED) The severity of the problem. Accepted values include:
-
- `critical'
- The product, component or concept is completely
- non-operational or some essential functionality is missing.
- No workaround is known.
-
- `serious'
- The product, component or concept is not working properly or
- significant functionality is missing. Problems that would
- otherwise be considered `critical' are rated `serious' when a
- workaround is known.
-
- `non-critical'
- The product, component or concept is working in general, but
- lacks features, has irritating behavior, does something
- wrong, or doesn't match its documentation. The default value
- is `serious'.
-
-`>Priority:'
- (ENUMERATED) How soon the originator requires a solution. Accepted
- values include:
-
- `high'
- A solution is needed as soon as possible.
-
- `medium'
- The problem should be solved in the next release.
-
- `low'
- The problem should be solved in a future release.
-
- The default value is `medium'.
-
-`>Category:'
- (TEXT) The name of the product, component or concept where the
- problem lies. The values for this field are defined by the Support
- Site.
-
-`>Class:'
- (ENUMERATED) The class of a problem can be one of the following:
-
- `sw-bug'
- A general product problem. (`sw' stands for "software".)
-
- `doc-bug'
- A problem with the documentation.
-
- `change-request'
- A request for a change in behavior, etc.
-
- `support'
- A support problem or question.
-
- `duplicate (PR-NUMBER)'
- Duplicate PR. PR-NUMBER should be the number of the original
- PR.
-
- The default is `sw-bug'.
-
-`>Release:'
- (TEXT) Release or version number of the product, component or
- concept.
-
-`>Environment:'
- (MULTITEXT) Description of the environment where the problem
- occured: machine architecture, operating system, host and target
- types, libraries, pathnames, etc.
-
-`>Description:'
- (MULTITEXT) Precise description of the problem.
-
-`>How-To-Repeat:'
- (MULTITEXT) Example code, input, or activities to reproduce the
- problem. The support organization uses example code both to
- reproduce the problem and to test whether the problem is fixed.
- Include all preconditions, inputs, outputs, conditions after the

-
-Creating new Problem Reports
-============================
-
- Invoking `send-pr' presents a PR "template" with a number of fields
-already filled in. Complete the template as thoroughly as possible to
-make a useful bug report. Submit only one bug with each PR.
-
- A template consists of three sections:
-
-"Comments"
- The top several lines of a blank template consist of a series of
- comments that provide some basic instructions for completing the
- Problem Report, as well as a list of valid entries for the
- `>Category:' field. These comments are all preceded by the string
- `SEND-PR:' and are erased automatically when the PR is submitted.
- The instructional comments within `<' and `>' are also removed.
- (Only these comments are removed; lines you provide that happen to
- have those characters in them, such as examples of shell-level
- redirection, are not affected.)
-
-"Mail Header"
- `send-pr' creates a standard mail header. `send-pr' completes all
- fields except the `Subject:' line with default values. (*Note
- Problem Report format: Fields.)
-
-"GNATS fields"
- These are the informational fields that GNATS uses to route your
- Problem Report to the responsible party for further action. They
- should be filled out as completely as possible. (*Note Problem
- Report format: Fields. Also see *Note Helpful hints: Helpful
- hints.)
-
-For examples of a Problem Report template and complete Problem Report,
-see *Note An Example::.
-
- The default template contains your preconfigured `>Submitter-Id:'.
-`send-pr' attempts to determine values for the `>Originator:' and
-`>Organization:' fields (*note Problem Report format: Fields.).
-`send-pr' also attempts to find out some information about your system
-and architecture, and places this information in the `>Environment:'
-field if it finds any.
-
- You may submit problem reports to different Support Sites from the
-default site by specifying the alternate site when you invoke
-`send-pr'. Each `site' has its own list of categories for which it
-accepts Problem Reports. (*Note Setting a default SITE: default site.)
-
- `send-pr' also provides the mail header section of the template with
-default values in the `To:', `From:', and `Reply-To:' fields. The
-`Subject:' field is empty.
-
- The template begins with a comment section:
-
- SEND-PR: -*- send-pr -*-
- SEND-PR: Lines starting with `SEND-PR' will be removed
- SEND-PR: automatically as well as all comments (the text
- SEND-PR: below enclosed in `<' and `>').
- SEND-PR:
- SEND-PR: Please consult the document `Reporting Problems
- SEND-PR: Using send-pr' if you are not sure how to fill out
- SEND-PR: a problem report.
- SEND-PR:
- SEND-PR: Choose from the following categories:
-
-and also contains a list of valid `>Category:' values for the Support
-Site to whom you are submitting this Problem Report. One (and only
-one) of these values should be placed in the `>Category:' field. A
-complete sample bug report, from template to completed PR, is shown in
-*Note An Example::. For a complete list of valid categories, type
-`send-pr -L' at your prompt. *Note Valid Categories: Valid Categories,
-for a sample list of categories, .
-
- The mail header is just below the comment section. Fill out the
-`Subject:' field, if it is not already completed using the value of
-`>Synopsis:'. The other mail header fields contain default values.
-
- To: SUPPORT-SITE
- Subject: *complete this field*
- From: YOUR-LOGIN@YOUR-SITE
- Reply-To: YOUR-LOGIN@YOUR-SITE
- X-send-pr-version: send-pr 3.2
-
-where SUPPORT-SITE is an alias for the Support Site you wish to submit
-this PR to.
-
- The rest of the template contains GNATS fields. Each field is
-either automatically completed with valid information (such as your
-`>Submitter-Id:') or contains a one-line instruction specifying the
-information that field requires in order to be correct. For example,
-the `>Confidential:' field expects a value of `yes' or `no', and the
-answer must fit on one line; similarly, the `>Synopsis:' field expects
-a short synopsis of the problem, which must also fit on one line. Fill
-out the fields as completely as possible. *Note Helpful hints: Helpful
-hints, for suggestions as to what kinds of information to include.
-
- In this example, words in *italics* are filled in with
-pre-configured information:
-
- >Submitter-Id: *your submitter-id*
- >Originator: *your name here*
- >Organization:
- *your organization*
- >Confidential:<[ yes | no ] (one line)>
- >Synopsis: <synopsis of the problem (one line)>
- >Severity: <[non-critical | serious | critical](one line)>
- >Priority: <[ low | medium | high ] (one line)>
- >Category: <name of the product (one line)>
- >Class: <[sw-bug | doc-bug | change-request | support]>
- >Release: <release number or tag (one line)>
- >Environment:
- <machine, os, target, libraries (multiple lines)>
-
- >Description:
- <precise description of the problem (multiple lines)>
- >How-To-Repeat:
- <code/input/activities to reproduce (multiple lines)>
- >Fix:
- <how to correct or work around the problem, if known
- (multiple lines)>
-
- When you finish editing the Problem Report, `send-pr' mails it to
-the address named in the `To:' field in the mail header. `send-pr'
-checks that the complete form contains a valid `>Category:'.
-
- Your copy of `send-pr' should have already been customized on
-installation to reflect your `>Submitter-Id:'. (*Note Installing
-`send-pr' on your system: Installing send-pr.) If you don't know your
-`>Submitter-Id:', you can request it using `send-pr --request-id'. If
-your organization is not affiliated with the site you send Problem
-Reports to, a good generic `>Submitter-Id:' to use is `net'.
-
- If your PR has an invalid value in one of the ENUMERATED fields
-(*note Problem Report format: Fields.), `send-pr' places the PR in a
-temporary file named `/tmp/pbadNNNN' on your machine. NNNN is the
-process identification number given to your current `send-pr' session.
-If you are running `send-pr' from the shell, you are prompted as to
-whether or not you wish to try editing the same Problem Report again.
-If you are running `send-pr' from Emacs, the Problem Report is placed
-in the buffer `*send-pr-error*'; you can edit this file and then submit
-it with
-
- M-x gnats-submit-pr
-
- Any further mail concerning this Problem Report should be
-carbon-copied to the GNATS mailing address as well, with the category
-and identification number in the `Subject:' line of the message.
-
- Subject: Re: PR CATEGORY/GNATS-ID: ORIGINAL MESSAGE SUBJECT
-
-Messages which arrive with `Subject:' lines of this form are
-automatically appended to the Problem Report in the `>Audit-Trail:'
-field in the order received.

-
-Using `send-pr' from within Emacs
-=================================
-
- You can use an interactive `send-pr' interface from within GNU Emacs
-to fill out your Problem Report. We recommend that you familiarize
-yourself with Emacs before using this feature (*note Introduction:
-(emacs)Introduction.).
-
- Call `send-pr' with `M-x send-pr'.(1) `send-pr' responds with a
-Problem Report template preconfigured for the Support Site from which
-you received `send-pr'. (If you use `send-pr' locally, the default
-Support Site is probably your local site.)
-
- You may also submit problem reports to different Support Sites from
-the default site. To use this feature, invoke `send-pr' with
-
- C-u M-x send-pr
-
- `send-pr' prompts you for the name of a SITE. SITE is an alias on
-your local machine which points to an alternate Support Site.
-
- `send-pr' displays the template and prompts you in the minibuffer
-with the line:
- >Category: other
-
-Delete the default value `other' *in the minibuffer* and replace it
-with the keyword corresponding to your problem (the list of valid
-categories is in the topmost section of the PR template). For example,
-if the problem you wish to report has to do with the GNU C compiler,
-and your support organization accepts bugs submitted for this program
-under the category `gcc', delete `other' and then type `gcc[RET]'.
-`send-pr' replaces the line
-
- >Category: <name of the product (one line)>
-
-in the template with
-
- >Category: gcc
-
-and moves on to another field.
-
- `send-pr' provides name completion in the minibuffer. For instance,
-you can also type `gc[TAB]', and `send-pr' attempts to complete the
-entry for you. Typing `g[TAB]' may not have the same effect if several
-possible entries begin with `g'. In that case `send-pr' cannot
-complete the entry because it cannot determine whether you mean `gcc'
-or, for example, `gdb', if both of those are possible categories.
-`send-pr' continues to prompt you for a valid entry until you enter one.
-
- `send-pr' prompts you interactively to enter each field for which
-there is a range of specific choices. If you attempt to enter a value
-which is not in the range of acceptable entries, `send-pr' responds
-with `[No match]' and allows you to change the entry until it contains
-an acceptable value. This avoids unusable information (at least in
-these fields) and also avoids typographical errors which could cause
-problems later.
-
- `send-pr' prompts you for the following fields:
-
- >Category:
- >Confidential: (*default*: no)
- >Severity: (*default*: serious)
- >Priority: (*default*: medium)
- >Class: (*default*: sw-bug)
- >Release:
- >Synopsis: (*this value is copied to `Subject:'*)
-
-After you complete these fields, `send-pr' places the cursor in the
-`>Description:' field and displays the message
-
- To send the problem report use: C-c C-c
-
-in the minibuffer. At this point, edit the file in the main buffer to
-reflect your specific problem, putting relevant information in the
-proper fields. *Note An Example::, for a sample Problem Report.
-
- `send-pr' provides a few key bindings to make moving around in a
-template buffer more simple:
-
-`C-c C-f'
-`M-x change-field'
- Changes the field under the cursor. `edit-pr' prompts you for a
- new value.
-
-`M-C-b'
-`M-x gnats-backward-field'
- Moves the cursor to the beginning of the value of the current
- field.
-
-`M-C-f'
-`M-x gnats-forward-field'
- Moves the cursor to the end of the value of the current field.
-
-`M-p'
-`M-x gnats-previous-field'
- Moves the cursor back one field to the beginning of the value of
- the previous field.
-
-`M-n'
-`M-x gnats-next-field'
- Moves the cursor forward one field to the beginning of the value
- of the next field.
-
- `send-pr' takes over again when you type `C-c C-c' to send the
-message. `send-pr' reports any errors in a separate buffer, which
-remains in existence until you send the PR properly (or, of course,
-until you explicitly kill the buffer).
-
- For detailed instructions on using Emacs, see *Note Introduction:
-(emacs)Introduction.

-Invoking `send-pr' from the shell
-=================================
-
- send-pr [ SITE ]
- [ -f PROBLEM-REPORT | --file PROBLEM-REPORT ]
- [ -t MAIL-ADDRESS | --to MAIL-ADDRESS ]
- [ --request-id ]
- [ -L | --list ] [ -P | --print ]
- [ -V | --version] [ -h | --help ]
-
- SITE is an alias on your local machine which points to an address
-used by a Support Site. If this argument is not present, the default
-SITE is usually the site which you received `send-pr' from, or your
-local site if you use GNATS locally. (*Note Setting a default SITE:
-default site.)
-
- Invoking `send-pr' with no options calls the editor named in your
-environment variable `EDITOR' on a default PR template. If the
-environment variable `PR_FORM' is set, its value is used as a file name
-which contains a valid template. If `PR_FORM' points to a missing or
-unreadable file, or if the file is empty, `send-pr' generates an error
-message and opens the editor on a default template.
-
-`-f PROBLEM-REPORT'
-`--file PROBLEM-REPORT'
- Specifies a file, PROBLEM-REPORT, where a completed Problem Report
- already exists. `send-pr' sends the contents of the file without
- invoking an editor. If PROBLEM-REPORT is `-', `send-pr' reads
- from standard input.
-
-`-t MAIL-ADDRESS'
-`--to MAIL-ADDRESS'
- Sends the PR to MAIL-ADDRESS. The default is preset when `send-pr'
- is configured. *This option is not recommended*; instead, use the
- argument SITE on the command line.
-
-`--request-id'
- Sends a request for a `>Submitter-Id:' to the Support Site.
-
-`-L'
-`--list'
- Prints the list of valid `>Category:' values on standard output.
- No mail is sent.
-
-`-P'
-`--print'
- Displays the PR template. If the variable `PR_FORM' is set in your
- environment, the file it specifies is printed. If `PR_FORM' is not
- set, `send-pr' prints the standard blank form. If the file
- specified by `PR_FORM' doesn't exist, `send-pr' displays an error
- message. No mail is sent.
-
-`-V'
-`--version'
- Displays the `send-pr' version number and a usage summary. No mail
- is sent.
-
-`-h'
-`--help'
- Displays a usage summary for `send-pr'. No mail is sent.

-Helpful hints
-=============
-
- There is no orthodox standard for submitting effective bug reports,
-though you might do well to consult the section on submitting bugs for
-GNU `gcc' in *Note Reporting Bugs: (gcc)Bugs, by Richard Stallman.
-This section contains instructions on what kinds of information to
-include and what kinds of mistakes to avoid.
-
- In general, common sense (assuming such an animal exists) dictates
-the kind of information that would be most helpful in tracking down and
-resolving problems in software.
- * Include anything *you* would want to know if you were looking at
- the report from the other end. There's no need to include every
- minute detail about your environment, although anything that might
- be different from someone else's environment should be included
- (your path, for instance).
-
- * Narratives are often useful, given a certain degree of restraint.
- If a person responsible for a bug can see that A was executed, and
- then B and then C, knowing that sequence of events might trigger
- the realization of an intermediate step that was missing, or an
- extra step that might have changed the environment enough to cause
- a visible problem. Again, restraint is always in order ("I set
- the build running, went to get a cup of coffee (Columbian, cream
- but no sugar), talked to Sheila on the phone, and then THIS
- happened...") but be sure to include anything relevant.
-
- * Richard Stallman writes, "The fundamental principle of reporting
- bugs usefully is this: *report all the facts*. If you are not sure
- whether to state a fact or leave it out, state it!" This holds
- true across all problem reporting systems, for computer software
- or social injustice or motorcycle maintenance. It is especially
- important in the software field due to the major differences
- seemingly insignificant changes can make (a changed variable, a
- missing semicolon, etc.).
-
- * Submit only *one* problem with each Problem Report. If you have
- multiple problems, use multiple PRs. This aids in tracking each
- problem and also in analyzing the problems associated with a given
- program.
-
- * It never hurts to do a little research to find out if the bug
- you've found has already been reported. Most software releases
- contain lists of known bugs in the Release Notes which come with
- the software; see your system administrator if you don't have a
- copy of these.
-
- * The more closely a PR adheres to the standard format, the less
- interaction is required by a database administrator to route the
- information to the proper place. Keep in mind that anything that
- requires human interaction also requires time that might be better
- spent in actually fixing the problem. It is therefore in
- everyone's best interest that the information contained in a PR be
- as correct as possible (in both format and content) at the time of
- submission.

-An Example
-**********
-
- Cygnus Support in Mountain View, CA, uses GNATS and `send-pr'
-extensively for their support activities. As a support company, Cygnus
-finds problem tracking to be a crucial part of everyday business.
-Cygnus supports the GNU compiling tools (including GNATS and `send-pr')
-over several many platforms
-
- With each shipment of the Cygnus Support Developer's Kit, customers
-receive the latest version of `send-pr', which contains an up-to-date
-listing of valid categories (values for the `>Category:' field). Using
-these tools, Cygnus' customers can communicate their problems to Cygnus
-effectively and receive automatic confirmation of receipt as well as
-notification of changes in the status of their reported problems. Much
-of Cygnus' support mechanism relies on electronic mail.
-
- As an example, let's pretend we're a customer of Cygnus Support, and
-that we're having a problem compiling some of our software using the
-GNU C compiler, which Cygnus supports.
-
- Assume that we're getting an error in our `bifrabulator' program
-wherein the `prestidigitation' routines don't match with the
-`whatsitsname'. We've made sure we're following the rules of the
-program and checked the Release Notes from Cygnus and found that the bug
-isn't already known. In other words, we're pretty sure we've found a
-bug.
-
- Our first step is to call `send-pr'. It really doesn't matter
-whether we use `send-pr' from the shell or from within Emacs. Indeed,
-if we use Emacs as a primary editor, calling `send-pr' from the shell
-is likely to start `send-pr' in an Emacs buffer anyway. So, since our
-company, *Imaginary Software, Ltd.*, uses GNU software extensively,
-we're pretty familiar with Emacs, so from within Emacs we type
- M-x send-pr
-
-and we're greeted with the following screen:
-
- SEND-PR: -*- text -*-
- SEND-PR: Lines starting with `SEND-PR' will be removed
- SEND-PR: automatically as well as all comments (the text

-Installing `send-pr' on your system
-***********************************
-
- If you receive `send-pr' as part of a larger software distribution,
-it probably gets installed when the full distribution is installed. If
-you are using GNATS at your site as well, you must decide where
-`send-pr' sends Problem Reports by default; see *Note Setting a default
-SITE: default site.
-
-* Menu:
-
-* installation:: installing `send-pr' by itself
-* default site:: setting a default site
-
-
-File: send-pr.info, Node: installation, Next: default site, Up: Installing send-pr
-
-Installing `send-pr' by itself
-==============================
-
- Install `send-pr' by following these steps (you may need `root'
-access in order to change the `aliases' file and to install `send-pr'):
-
- * Unpack the distribution into a directory which we refer to as
- SRCDIR.
-
- * Edit the file `Makefile' to reflect local conventions.
- Specifically, you should edit the variable `prefix' to alter the
- installation location. The default is `/usr/local'. All files are
- installed under `prefix' (see below).
-
- * *Run*
- make all install [ info ] [ install-info ] [ clean ]
-
- The targets mean the following:
-
- `all'
- Builds `send-pr' and `install-sid'
-
- `install'
- Installs the following:
-
- `install-sid'
- `send-pr'
- into `PREFIX/bin'
-
- `send-pr.1'
- into `PREFIX/man/man1'
-
- `SITE'
- the list of valid CATEGORIES for the Support Site from
- which you received `send-pr', installed as
- `PREFIX/lib/gnats/SITE'
-
- `send-pr.el'
- into `PREFIX/lib/emacs/lisp'(1)
-
- `info (*optional*)'
- Builds `send-pr.info' from `send-pr.texi'
- (`send-pr.info' is included with this distribution)
-
- `install-info (*optional*)'
- Installs `send-pr.info' into `PREFIX/info'
-
- `clean (*optional*)'
- Removes all intermediary build files that can be rebuilt from
- source code
-
- * Run
-
- install-sid YOUR-SID
-
- where YOUR-SID is the identification code you received with
- `send-pr'. `send-pr' automatically inserts this value into the
- template field `>Submitter-Id:'. If you've downloaded `send-pr'
- from the Net, use `net' for this value.
-
- * Place the following line in `PREFIX/lib/emacs/lisp/default.el', or
- instruct your users to place the following line in their `.emacs'
- files:
-
- (autoload 'send-pr "send-pr" "Submit a Problem Report." t)
-
- * Create a mail alias for the Support Site from which you received
- `send-pr', and for every site with which you wish to use `send-pr'
- to communicate. Each alias must have a suffix of `-gnats'. The
- Support Site(s) will provide the correct addresses where these
- aliases should point. For instance, edit your mail aliases file
- to contain something like:
-
- # support sites; for use with send-pr
- cygnus-gnats: bugs@cygnus.com # Cygnus Support
- bumblebee-gnats: bumblebugs@bumblebee.com # Bumblebee Inc.
- mycompany-gnats: bugs@my.company.com (*if you use GNATS locally*)
-
- `send-pr' automatically searches for these aliases when you type
-
- send-pr cygnus
- send-pr bumblebee
- send-pr SITE...
-
- `send-pr' also uses SITE to determine the categories of problems
- accepted by the site in question by looking in
-
- PREFIX/lib/gnats/SITE
-
- ---------- Footnotes ----------
-
- (1) If your main Emacs lisp repository is in a different directory
-from this, substitute that directory for `PREFIX/lib/emacs/lisp'.
-
-
-File: send-pr.info, Node: default site, Prev: installation, Up: Installing send-pr
-
-Setting a default SITE
-======================
-
- `send-pr' is capable of sending Problem Reports to any number of
-Support Sites, using mail aliases which have `-gnats' appended them.
-`send-pr' automatically appends the suffix, so that when you type
-
- send-pr SITE
-
-the Problem Report goes to the address noted in the `aliases' file as
-`SITE-gnats'. You can do this in the Emacs version of `send-pr' by
-invoking the program with
-
- C-u M-x send-pr
-
-You are prompted for SITE.
-
- SITE is also used to error-check the `>Category:' field, as a
-precaution against sending mistaken information (and against sending
-information to the wrong site).
-
- You may also simply type
-
- send-pr
-
-from the shell (or `M-x send-pr' in Emacs), and the Problem Report you
-generate will be sent to the SITE, which is usually the site from which
-you received your distribution of `send-pr'. If you use GNATS at your
-own organization, the default is usually your local address for
-reporting problems.
-
- To change this, simply edit the file `Makefile' before installing
-and change the line
-
- GNATS_SITE = SITE
-
-to reflect the site where you wish to send PRs by default.

-This manual documents @code{send-pr},
-@ifinfo
-version @value{VERSION},
-@end ifinfo
-which uses electronic mail to submit support questions and problem
-reports to a central Support Site. No body of work is perfect, and
-support organizations understand this; @code{send-pr} is designed to
-allow users who have problems to submit reports of these problems to
-sites responsible for supporting the products in question, in a defined
-form which can be read by an electronically managed database.
-
-@cindex GNATS
-@code{send-pr} is part of a suite of programs known collectively as
-@sc{gnats}, the @sc{gnu} Problem Report Management System. @sc{gnats}
-consists of several programs which, used in concert, formulate and
-partially administer a database of @dfn{Problem Reports}, or @dfn{PRs},
-at a central Support Site. A PR goes through several states in its
-lifetime; @sc{gnats} tracks the PR and all information associated with it
-through each state and finally acts as an archive for PRs which have
-been @dfn{closed}.
-
-Because @code{send-pr} exists as a shell (@file{/bin/sh}) script and as
-an Elisp file for use with @sc{gnu} Emacs, it can be used from any
-machine on your network which can run a shell script and/or Emacs.
-
-In general, you can use any editor and mailer to submit valid Problem
-Reports, as long as the format required by @sc{gnats} is preserved.
-@code{send-pr} automates the process, however, and ensures that certain
-fields necessary for automatic processing are present. @code{send-pr}
-is strongly recommended for all initial problem-oriented correspondence
-with your Support Site. The organization you submit Problem Reports to
-supplies an address to which further information can be sent; the person
-responsible for the category of the problem you report contacts you
-directly.

-A @dfn{Problem Report} is a message that describes a problem you are
-having with a body of work. @code{send-pr} organizes this message into
-a form which can be understood and automatically processed by @sc{gnats},
-the @sc{gnu} Problem Report Management System. A Problem Report is
-organized into @dfn{fields} which contain data describing you, your
-organization, and the problem you are announcing (@pxref{Fields,,Problem
-Report format}). Problem Reports go through several defined states in
-their lifetimes, from @dfn{open} to @dfn{closed} (@pxref{States,,States

-@cindex GNU software support
-
-Cygnus Support in Mountain View, CA, uses @sc{gnats} and @code{send-pr}
-extensively for their support activities. As a support company, Cygnus
-finds problem tracking to be a crucial part of everyday business.
-Cygnus supports the @sc{gnu} compiling tools (including @sc{gnats} and
-@code{send-pr}) over several many platforms
-
-With each shipment of the Cygnus Support Developer's Kit, customers
-receive the latest version of @code{send-pr}, which contains an
-up-to-date listing of valid categories (values for the @code{>Category:}
-field). Using these tools, Cygnus' customers can communicate their
-problems to Cygnus effectively and receive automatic confirmation of
-receipt as well as notification of changes in the status of their
-reported problems. Much of Cygnus' support mechanism relies on
-electronic mail.
-
-As an example, let's pretend we're a customer of Cygnus Support, and
-that we're having a problem compiling some of our software using the
-@sc{gnu} C compiler, which Cygnus supports.
-
-Assume that we're getting an error in our @code{bifrabulator} program
-wherein the @samp{prestidigitation} routines don't match with the
-@samp{whatsitsname}. We've made sure we're following the rules of the
-program and checked the Release Notes from Cygnus and found that the bug
-isn't already known. In other words, we're pretty sure we've found a
-bug.
-
-@cindex Imaginary Software, Ltd.
-Our first step is to call @code{send-pr}. It really doesn't matter
-whether we use @code{send-pr} from the shell or from within Emacs.
-Indeed, if we use Emacs as a primary editor, calling @code{send-pr} from
-the shell is likely to start @code{send-pr} in an Emacs buffer anyway.
-So, since our company, @emph{Imaginary Software, Ltd.}, uses @sc{gnu}
-software extensively, we're pretty familiar with Emacs, so from within
-Emacs we type
-@smallexample
-M-x send-pr
-@end smallexample

-Got your message, Jeff. It seems that the bifrabulator was
-confusing the prestidigitation routines with the realitychecker
-when lexically parsing the whatsitsname.
-
-I'm working on robustisizing the bifrabulator now.
-
-How about lunch next week?

-Create a mail alias for the Support Site from which you received

-@code{send-pr} to communicate. Each alias must have a suffix of
-@samp{-gnats}. The Support Site(s) will provide the correct addresses
-where these aliases should point. For instance, edit your mail aliases
-file to contain something like:
-
-@smallexample
-# support sites; for use with send-pr
-cygnus-gnats: bugs@@cygnus.com # Cygnus Support
-bumblebee-gnats: bumblebugs@@bumblebee.com # Bumblebee Inc.
-mycompany-gnats: bugs@@my.company.com (@emph{if you use @sc{gnats} locally})

-@code{send-pr} is capable of sending Problem Reports to any number of

-@code{send-pr} automatically appends the suffix, so that when you type
-
-@smallexample
-send-pr @var{site}
-@end smallexample
-
-@noindent
-the Problem Report goes to the address noted in the @file{aliases} file
-as @w{@samp{@var{site}-gnats}}. You can do this in the Emacs version of
-@code{send-pr} by invoking the program with
-
-@smallexample
-C-u M-x send-pr
-@end smallexample
-
-@noindent
-You are prompted for @var{site}.
-
-@var{site} is also used to error-check the @samp{>Category:} field, as a
-precaution against sending mistaken information (and against sending
-information to the wrong site).
-
-You may also simply type
-
-@smallexample
-send-pr
-@end smallexample
-
-@noindent
-from the shell (or @w{@samp{M-x send-pr}} in Emacs), and the Problem
-Report you generate will be sent to the @var{site}, which is usually the
-site from which you received your distribution of @w{@code{send-pr}}.
-If you use @sc{gnats} at your own organization, the default is usually
-your local address for reporting problems.
-
-To change this, simply edit the file @file{Makefile} before installing
-and change the line
-
-@smallexample
-GNATS_SITE = @var{site}
-@end smallexample

-.Sh NAME
-.Nm ypserv
-.Nd "NIS database server"
-.Sh SYNOPSIS
-.Nm ypserv
-.Op Fl dns
-.Op Fl debug
-.Op Fl k
-.Op Fl p Ar port
-.Sh DESCRIPTION
-.Nm NIS
-is an RPC-based service designed to allow a number of UNIX-based
-machines to share a common set of configuration files. Rather than
-requiring a system administrator to update several copies of files
-such as
-.Pa /etc/hosts ,
-.Pa /etc/passwd
-and
-.Pa /etc/group ,
-which tend to require frequent changes in most environments, NIS
-allows groups of computers to share one set of data which can be
-updated from a single location.
-.Pp
-.Nm ypserv
-is the server that distributes NIS databases
-to client systems within an NIS
-.Nm domain.
-Each client in an NIS domain must have its domainname set to
-one of the domains served by
-.Nm ypserv
-using the
-.Xr domainname 1
-command. The clients must also run
-.Xr ypbind 8
-in order to attach to a particular server, since it is possible to
-have serveral servers within a single NIS domain.
-.Pp
-The databases distributed by
-.Nm ypserv
-are stored in
-.Pa /var/yp/[domainname]
-where
-.Pa domainname
-is the name of the domain being served. There can be several
-such directories with different domainnames, and
-.Nm ypserv
-can handle them all.
-.Pp
-The databases, or
-.Pa maps
-as they are often called,
-are created by
-.Nm /var/yp/Makefile
-using several system files as source. The database files are in
-.Xr db 3
-format to help speed retrieval when there are many records involved.
-In FreeBSD, the
-maps are always readable and writable only by root for security
-reasons. Technically this is only necessary for the password
-maps, but since the data in the other maps can be found in
-other world-readable files anyway, it doesn't hurt and it's considered
-good general practice.
-.Pp
-.Nm ypserv
-is started by
-.Nm /etc/rc
-if it has been enabled in
-.Nm /etc/sysconfig.
-.Sh SPECIAL FEATURES
-There are some problems associated with distributing FreeBSD's password
-database via NIS: FreeBSD normally only stores encrypted passwords
-in
-.Pa /etc/master.passwd ,
-which is readable and writable only by root. By turning this file
-into an NIS map, this security feature would be completely defeated.
-.Pp
-To make up for this, the FreeBSD version of
-.Nm ypserv
-handles the
-.Pa master.passwd.byname
-and
-.Pa master.basswd.byuid
-maps in a special way. When the server receives a request to access
-either of these two maps, it will check the TCP port from which the
-request originated and return an error if the port number is greater
-than 1023. Since only the superuser is allowed to bind to TCP ports
-with values less than 1024, the server can use this test to determine
-whether or not the access request came from a privileged user.
-Any requests made by non-privileged users are therefore rejected.
-.Pp
-Furthermore, the
-.Xr getpwent 3
-routines in FreeBSD's standard C libarary will only attempt to retrieve
-data from the
-.Pa master.passwd.byname
-and
-.Pa master.passwd.byuid
-maps for the superuser: if a normal user calls any of these functions,
-the standard
-.Pa passwd.byname
-and
-.Pa passwd.byuid
-maps will be accessed instead. The latter two maps are constructed by
-.Nm /var/yp/Makefile
-by parsing the
-.Pa master.passwd
-file and stripping out the password fields, and are therefore
-safe to pass on to unprivileged users. In this way, the shadow password
-aspect of the protected
-.Pa master.passwd
-database is maintained through NIS.
-.Pp
-.Sh NOTES
-.Ss Limitations
-There are two problems inherent with password shadowing in NIS
-that users should
-be aware of:
-.Bl -enum -offset indent
-.It
-The 'TCP port less than 1024' test is trivial to defeat for users with
-unrestricted access to machines on your network (even those machines
-which do not run UNIX-based operating systems).
-.It
-If you plan to use a FreeBSD system to serve non-FreeBSD clients that
-have no support for password shadowing (which is most of them), you
-will have to disable the password shadowing entirely by uncommenting the
-.Nm UNSECURE=True
-entry in
-.Nm /var/yp/Makefile .
-This will cause the standard
-.Pa passwd.byname
-and
-.Pa passwd.byuid
-maps to be generated with valid encrypted password fields, which is
-neccesary in order for non-FreeBSD clients to perform user
-authentication through NIS.
-.El
-.Pp
-.Ss Security
-.Nm ypserv
-has support for Wietse Venema's
-.Pa tcpwrapper
-package built in, though it is not compiled in by default since
-the
-.Pa tcpwrapper
-package is not distributed with FreeBSD. However, if you have
-.Nm libwrap.a
-and
-.Nm tcpd.h ,
-you can easily recompile
-.Nm ypserv
-with them, thereby enabling its 'securenets' features: you can
-configure
-.Nm ypserv
-to only handle resquests from machines listed
-in the
-.Pa tcpwrapper
-configuration files, which would help limit vulnerability to the
-first limitation listed above.
-.Pp
-.Ss NIS servers that are also NIS clients
-Care must be taken when running
-.Nm ypserv
-in a multi-server domain where the server machines are also
-NIS clients. It is generally a good idea to force the servers to
-bind to themselves rather than allowing them to broadcast bind
-requests and possibly become bound to each other: strange failure
-modes can result if one server goes down and
-others are dependent upon on it. (Eventually all the clients will
-time out and attempt to bind to other servers, but the delay
-involved can be considerable and the failure mode is still present
-since the servers might bind to each other all over again).
-.Pp
-Refer to the
-.Xr ypbind 8
-man page for details on how to force it to bind to a particular
-server.
-.Sh OPTIONS
-The following options are supported by
-.Nm ypserv :
-.Bl -tag -width flag
-.It Fl dns
-This option affects the way
-.Nm ypserv
-handles yp_match requests for the
-.Pa hosts.byname
-and
-.Pa hosts.byaddress
-maps. By default, if
-.Nm ypserv
-can't find an entry for a given host in its hosts maps, it will
-return an error and perform no further processing. With the
-.Fl dns
-flag,
-.Nm ypserv
-will go one step further: rather than giving up immediately, it
-will try to resolve the hostname or address using a DNS query.
-If the query is successful,
-.Nm ypserv
-will construct a fake database record and return it to the client,
-thereby making it seem as though the client's yp_match request
-succeeded.
-.Pp
-This functionality is provided for compatiblity with SunOS 4.1.x,
-which has brain-damaged resolver functions in its standard C
-library that depend on NIS for hostname and address resolution.
-FreeBSD's resolver can be configured to do DNS
-queries directly, therefore it is not necessary to enable this
-option when serving only FreeBSD NIS clients.
-.It Fl debug
-Run the server in debugging mode: the server does not background
-itself and prints copious debugging output to stderr for
-each
-request that it revceives.
-.It Fl k
-This flag is provided for compatibility with SunOS 4. The
-.Xr ypbind 8
-command in SunOS 4 apparently expects to obtain a response from an
-NIS v1 server. Starting
-.Xr ypserv 8
-with the
-.Fl k
-flag causes it to register itself as an NIS v1 server and
-respond to DOMAIN_NONACK requests. Note carefully: this is merely a
-kludge (hence the 'k') to pacify SunOS 4's
-.Xr ypbind 8
-command: attempts to make the server actually handle NIS v1 queries
-will undoubtedly fail quite miserably.
-.It Fl p Ar port
-Normally,
-.Nm ypserv
-will bind itself to a randomly chosen TCP port when it is first
-started. This option can be used to force the server to bind to
-a particular port instead.
