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. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. 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. - - 1. 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. - - 2. 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. - - 3. 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. - - 4. 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. - - 5. 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. - - 6. 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. - - 7. 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. - - 8. 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. - - 9. 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. - - 10. 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 - - 11. 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. - - 12. 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 OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - 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. diff --git a/contrib/gdb/bfd/Makefile.in b/contrib/gdb/bfd/Makefile.in deleted file mode 100644 index e531cf8..0000000 --- a/contrib/gdb/bfd/Makefile.in +++ /dev/null @@ -1,1090 +0,0 @@ -# Makefile template for Configure for the BFD library. -# Copyright (C) 1990, 91, 92, 93, 94, 95, 1996 -# Free Software Foundation, Inc. -# Written by Cygnus Support. -# -# This file is part of BFD, the Binary File Descriptor library. -# -# 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.

One - derivation file is @file{aoutf1.h} (for a.out flavour 1), and - adds to the basic a.out functions support for sun3, sun4, 386 - and 29k a.out files, to create a target jump vector for a - specific target. - - This information is further split out into more specific files - for each machine, including @file{sunos.c} for sun3 and sun4, - @file{newsos3.c} for the Sony NEWS, and @file{demo64.c} for a - demonstration of a 64 bit a.out format. - - The base file @file{aoutx.h} defines general mechanisms for - reading and writing records to and from disk and various - other methods which BFD requires. It is included by - @file{aout32.c} and @file{aout64.c} to form the names - <<aout_32_swap_exec_header_in>>, <<aout_64_swap_exec_header_in>>, etc. - - As an example, this is what goes on to make the back end for a - sun4, from @file{aout32.c}: - -| #define ARCH_SIZE 32 -| #include "aoutx.h" - - Which exports names: - -| ... -| aout_32_canonicalize_reloc -| aout_32_find_nearest_line -| aout_32_get_lineno -| aout_32_get_reloc_upper_bound -| ... - - from @file{sunos.c}: - -| #define TARGET_NAME "a.out-sunos-big" -| #define VECNAME sunos_big_vec -| #include "aoutf1.h" - - requires all the names from @file{aout32.c}, and produces the jump vector - -| sunos_big_vec - - The file @file{host-aout.c} is a special case. It is for a large set - of hosts that use ``more or less standard'' a.out files, and - for which cross-debugging is not interesting. It uses the - standard 32-bit a.out support routines, but determines the - file offsets and addresses of the text, data, and BSS - sections, the machine architecture and machine type, and the - entry point address, in a host-dependent manner.

It has a symbol - table, although there's not much a user program will do with it. - - The big difference between an archive BFD and an ordinary BFD - is that the archive doesn't have sections. Instead it has a - chain of BFDs that are considered its contents. These BFDs can - be manipulated like any other. The BFDs contained in an - archive opened for reading will all be opened for reading. You - may put either input or output BFDs into an archive opened for - output; they will be handled correctly when the archive is closed. - - Use <<bfd_openr_next_archived_file>> to step through - the contents of an archive opened for input. You don't - have to read the entire archive if you don't want - to! Read it until you find what you want. - - Archive contents of output BFDs are chained through the - <<next>> pointer in a BFD. The first one is findable through - the <<archive_head>> slot of the archive. Set it with - <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one - open output archive at a time. - - As expected, the BFD archive code is more general than the - archive code of any given environment. BFD archives may - contain files of different formats (e.g., a.out and coff) and - even different architectures. You may even place archives - recursively into archives! - - This can cause unexpected confusion, since some archive - formats are more expressive than others. For instance, Intel - COFF archives can preserve long filenames; SunOS a.out archives - cannot. If you move a file from the first to the second - format and back again, the filename may be truncated. - Likewise, different a.out environments have different - conventions as to how they truncate filenames, whether they - preserve directory names in filenames, etc. When - interoperating with native tools, be sure your files are - homogeneous. - - Beware: most of these formats do not react well to the - presence of spaces in filenames. We do the best we can, but - can't always handle this case due to restrictions in the format of - archives. Many Unix utilities are braindead in regards to - spaces and such in filenames anyway, so this shouldn't be much - of a restriction. - - Archives are supported in BFD in <<archive.c>>. - -*/ - -/* Assumes: - o - all archive elements start on an even boundary, newline padded; - o - all arch headers are char *; - o - all arch headers are the same size (across architectures). -*/ - -/* Some formats provide a way to cram a long filename into the short - (16 chars) space provided by a BSD archive. The trick is: make a - special "file" in the front of the archive, sort of like the SYMDEF - entry. If the filename is too long to fit, put it in the extended - name table, and use its index as the filename. To prevent - confusion prepend the index with a space. This means you can't - have filenames that start with a space, but then again, many Unix - utilities can't handle that anyway. - - This scheme unfortunately requires that you stand on your head in - order to write an archive since you need to put a magic file at the - front, and need to touch every entry to do so. C'est la vie. - - We support two variants of this idea: - The SVR4 format (extended name table is named "//"), - and an extended pseudo-BSD variant (extended name table is named - "ARFILENAMES/"). The origin of the latter format is uncertain. - - BSD 4.4 uses a third scheme: It writes a long filename - directly after the header.

For - example, The 88k bcs coff format is implemented in the file - @file{coff-m88k.c}. This file @code{#include}s - @file{coff/m88k.h} which defines the external structure of the - coff format for the 88k, and @file{coff/internal.h} which - defines the internal structure. @file{coff-m88k.c} also - defines the relocations used by the 88k format - @xref{Relocations}. - - The Intel i960 processor version of coff is implemented in - @file{coff-i960.c}. This file has the same structure as - @file{coff-m88k.c}, except that it includes @file{coff/i960.h} - rather than @file{coff-m88k.h}. - -SUBSECTION - Porting to a new version of coff - - The recommended method is to select from the existing - implementations the version of coff which is most like the one - you want to use. For example, we'll say that i386 coff is - the one you select, and that your coff flavour is called foo. - Copy @file{i386coff.c} to @file{foocoff.c}, copy - @file{../include/coff/i386.h} to @file{../include/coff/foo.h}, - and add the lines to @file{targets.c} and @file{Makefile.in} - so that your new back end is used. Alter the shapes of the - structures in @file{../include/coff/foo.h} so that they match - what you need. You will probably also have to add - @code{#ifdef}s to the code in @file{coff/internal.h} and - @file{coffcode.h} if your version of coff is too wild. - - You can verify that your new BFD backend works quite simply by - building @file{objdump} from the @file{binutils} directory, - and making sure that its version of what's going on and your - host system's idea (assuming it has the pretty standard coff - dump utility, usually called @code{att-dump} or just - @code{dump}) are the same. Then clean up your code, and send - what you've done to Cygnus. Then your stuff will be in the - next release, and you won't have to keep integrating it. - -SUBSECTION - How the coff backend works - -SUBSUBSECTION - File layout - - The Coff backend is split into generic routines that are - applicable to any Coff target and routines that are specific - to a particular target. The target-specific routines are - further split into ones which are basically the same for all - Coff targets except that they use the external symbol format - or use different values for certain constants. - - The generic routines are in @file{coffgen.c}. These routines - work for any Coff target. They use some hooks into the target - specific code; the hooks are in a @code{bfd_coff_backend_data} - structure, one of which exists for each target. - - The essentially similar target-specific routines are in - @file{coffcode.h}. This header file includes executable C code. - The various Coff targets first include the appropriate Coff - header file, make any special defines that are needed, and - then include @file{coffcode.h}. - - Some of the Coff targets then also have additional routines in - the target source file itself. - - For example, @file{coff-i960.c} includes - @file{coff/internal.h} and @file{coff/i960.h}. It then - defines a few constants, such as @code{I960}, and includes - @file{coffcode.h}. Since the i960 has complex relocation - types, @file{coff-i960.c} also includes some code to - manipulate the i960 relocs. This code is not in - @file{coffcode.h} because it would not be used by any other - target. - -SUBSUBSECTION - Bit twiddling - - Each flavour of coff supported in BFD has its own header file - describing the external layout of the structures. There is also - an internal description of the coff layout, in - @file{coff/internal.h}. A major function of the - coff backend is swapping the bytes and twiddling the bits to - translate the external form of the structures into the normal - internal form. This is all performed in the - @code{bfd_swap}_@i{thing}_@i{direction} routines. Some - elements are different sizes between different versions of - coff; it is the duty of the coff version specific include file - to override the definitions of various packing routines in - @file{coffcode.h}. E.g., the size of line number entry in coff is - sometimes 16 bits, and sometimes 32 bits. @code{#define}ing - @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the - correct one. No doubt, some day someone will find a version of - coff which has a varying field size not catered to at the - moment. To port BFD, that person will have to add more @code{#defines}. - Three of the bit twiddling routines are exported to - @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in} - and @code{coff_swap_linno_in}. @code{GDB} reads the symbol - table on its own, but uses BFD to fix things up. More of the - bit twiddlers are exported for @code{gas}; - @code{coff_swap_aux_out}, @code{coff_swap_sym_out}, - @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out}, - @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out}, - @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track - of all the symbol table and reloc drudgery itself, thereby - saving the internal BFD overhead, but uses BFD to swap things - on the way out, making cross ports much safer. Doing so also - allows BFD (and thus the linker) to use the same header files - as @code{gas}, which makes one avenue to disaster disappear. - -SUBSUBSECTION - Symbol reading - - The simple canonical form for symbols used by BFD is not rich - enough to keep all the information available in a coff symbol - table. The back end gets around this problem by keeping the original - symbol table around, "behind the scenes". - - When a symbol table is requested (through a call to - @code{bfd_canonicalize_symtab}), a request gets through to - @code{coff_get_normalized_symtab}. This reads the symbol table from - the coff file and swaps all the structures inside into the - internal form. It also fixes up all the pointers in the table - (represented in the file by offsets from the first symbol in - the table) into physical pointers to elements in the new - internal table. This involves some work since the meanings of - fields change depending upon context: a field that is a - pointer to another structure in the symbol table at one moment - may be the size in bytes of a structure at the next. Another - pass is made over the table. All symbols which mark file names - (<<C_FILE>> symbols) are modified so that the internal - string points to the value in the auxent (the real filename) - rather than the normal text associated with the symbol - (@code{".file"}). - - At this time the symbol names are moved around. Coff stores - all symbols less than nine characters long physically - within the symbol table; longer strings are kept at the end of - the file in the string table. This pass moves all strings - into memory and replaces them with pointers to the strings. - - - The symbol table is massaged once again, this time to create - the canonical table used by the BFD application. Each symbol - is inspected in turn, and a decision made (using the - @code{sclass} field) about the various flags to set in the - @code{asymbol}. @xref{Symbols}. The generated canonical table - shares strings with the hidden internal symbol table. - - Any linenumbers are read from the coff file too, and attached - to the symbols which own the functions the linenumbers belong to. - -SUBSUBSECTION - Symbol writing - - Writing a symbol to a coff file which didn't come from a coff - file will lose any debugging information. The @code{asymbol} - structure remembers the BFD from which the symbol was taken, and on - output the back end makes sure that the same destination target as - source target is present. - - When the symbols have come from a coff file then all the - debugging information is preserved. - - Symbol tables are provided for writing to the back end in a - vector of pointers to pointers. This allows applications like - the linker to accumulate and output large symbol tables - without having to do too much byte copying. - - This function runs through the provided symbol table and - patches each symbol marked as a file place holder - (@code{C_FILE}) to point to the next file place holder in the - list. It also marks each @code{offset} field in the list with - the offset from the first symbol of the current symbol. - - Another function of this procedure is to turn the canonical - value form of BFD into the form used by coff. Internally, BFD - expects symbol values to be offsets from a section base; so a - symbol physically at 0x120, but in a section starting at - 0x100, would have the value 0x20. Coff expects symbols to - contain their final value, so symbols have their values - changed at this point to reflect their sum with their owning - section. This transformation uses the - <<output_section>> field of the @code{asymbol}'s - @code{asection} @xref{Sections}. - - o <<coff_mangle_symbols>> - - This routine runs though the provided symbol table and uses - the offsets generated by the previous pass and the pointers - generated when the symbol table was read in to create the - structured hierachy required by coff. It changes each pointer - to a symbol into the index into the symbol table of the asymbol. - - o <<coff_write_symbols>> - - This routine runs through the symbol table and patches up the - symbols from their internal form into the coff way, calls the - bit twiddlers, and writes out the table to the file. - -*/ - -/* -INTERNAL_DEFINITION - coff_symbol_type - -DESCRIPTION - The hidden information for an <<asymbol>> is described in a - <<combined_entry_type>>: - -CODE_FRAGMENT -. -.typedef struct coff_ptr_struct -.{ -. -. {* Remembers the offset from the first symbol in the file for -. this symbol.

The mapping is -defined within @code{bfd.h} in a set of macros, all beginning -with @samp{bfd_} to reduce namespace pollution. - -For example, this sequence does what you would probably expect: -return the number of sections in an object file attached to a BFD -@code{abfd}. - -@lisp -@c @cartouche -#include "bfd.h" - -unsigned int number_of_sections(abfd) -bfd *abfd; -@{ - return bfd_count_sections(abfd); -@} -@c @end cartouche -@end lisp - -The abstraction used within BFD is that an object file has: - -@itemize @bullet -@item -a header, -@item -a number of sections containing raw data (@pxref{Sections}), -@item -a set of relocations (@pxref{Relocations}), and -@item -some symbol information (@pxref{Symbols}). -@end itemize -@noindent -Also, BFDs opened for archives have the additional attribute of an index -and contain subordinate BFDs.

Each BFD back end provides a routine for converting -between the object file's representation of symbols and an internal -canonical format. When the linker asks for the symbol table of an object -file, it calls through a memory pointer to the routine from the -relevant BFD back end which reads and converts the table into a canonical -form. The linker then operates upon the canonical form. When the link is -finished and the linker writes the output file's symbol table, -another BFD back end routine is called to take the newly -created symbol table and convert it into the chosen output format. - -@menu -* BFD information loss:: Information Loss -* Canonical format:: The BFD canonical object-file format -@end menu - -@node BFD information loss -@subsection Information Loss - -@emph{Information can be lost during output.} The output formats -supported by BFD do not provide identical facilities, and -information which can be described in one form has nowhere to go in -another format. One example of this is alignment information in -@code{b.out}. There is nowhere in an @code{a.out} format file to store -alignment information on the contained data, so when a file is linked -from @code{b.out} and an @code{a.out} image is produced, alignment -information will not propagate to the output file. (The linker will -still use the alignment information internally, so the link is performed -correctly). - -Another example is COFF section names. COFF files may contain an -unlimited number of sections, each one with a textual section name. If -the target of the link is a format which does not have many sections (e.g., -@code{a.out}) or has sections without names (e.g., the Oasys format), the -link cannot be done simply. You can circumvent this problem by -describing the desired input-to-output section mapping with the linker command -language. - -@emph{Information can be lost during canonicalization.} The BFD -internal canonical form of the external formats is not exhaustive; there -are structures in input formats for which there is no direct -representation internally. This means that the BFD back ends -cannot maintain all possible data richness through the transformation -between external to internal and back to external formats. - -This limitation is only a problem when an application reads one -format and writes another. Each BFD back end is responsible for -maintaining as much data as possible, and the internal BFD -canonical form has structures which are opaque to the BFD core, -and exported only to the back ends. When a file is read in one format, -the canonical form is generated for BFD and the application. At the -same time, the back end saves away any information which may otherwise -be lost. If the data is then written back in the same format, the back -end routine will be able to use the canonical form provided by the -BFD core as well as the information it prepared earlier. Since -there is a great deal of commonality between back ends, -there is no information lost when -linking or copying big endian COFF to little endian COFF, or @code{a.out} to -@code{b.out}. When a mixture of formats is linked, the information is -only lost from the files whose format differs from the destination. - -@node Canonical format -@subsection The BFD canonical object-file format - -The greatest potential for loss of information occurs when there is the least -overlap between the information provided by the source format, that -stored by the canonical format, and that needed by the -destination format. A brief description of the canonical form may help -you understand which kinds of data you can count on preserving across -conversions. -@cindex BFD canonical format -@cindex internal object-file format - -@table @emph -@item files -Information stored on a per-file basis includes target machine -architecture, particular implementation format type, a demand pageable -bit, and a write protected bit. Information like Unix magic numbers is -not stored here---only the magic numbers' meaning, so a @code{ZMAGIC} -file would have both the demand pageable bit and the write protected -text bit set. The byte order of the target is stored on a per-file -basis, so that big- and little-endian object files may be used with one -another. - -@item sections -Each section in the input file contains the name of the section, the -section's original address in the object file, size and alignment -information, various flags, and pointers into other BFD data -structures. - -@item symbols -Each symbol contains a pointer to the information for the object file -which originally defined it, its name, its value, and various flag -bits. When a BFD back end reads in a symbol table, it relocates all -symbols to make them relative to the base of the section where they were -defined. Doing this ensures that each symbol points to its containing -section. Each symbol also has a varying amount of hidden private data -for the BFD back end. Since the symbol points to the original file, the -private data format for that symbol is accessible. @code{ld} can -operate on a collection of symbols of wildly different formats without -problems. - -Normal global and simple local symbols are maintained on output, so an -output file (no matter its format) will retain symbols pointing to -functions and to global, static, and common variables. Some symbol -information is not worth retaining; in @code{a.out}, type information is -stored in the symbol table as long symbol names. This information would -be useless to most COFF debuggers; the linker has command line switches -to allow users to throw it away. - -There is one word of type information within the symbol, so if the -format supports symbol type information within symbols (for example, COFF, -IEEE, Oasys) and the type is simple enough to fit within one word -(nearly everything but aggregates), the information will be preserved. - -@item relocation level -Each canonical BFD relocation record contains a pointer to the symbol to -relocate to, the offset of the data to relocate, the section the data -is in, and a pointer to a relocation type descriptor. Relocation is -performed by passing messages through the relocation type -descriptor and the symbol pointer. Therefore, relocations can be performed -on output data using a relocation method that is only available in one of the -input formats. For instance, Oasys provides a byte relocation format. -A relocation record requesting this relocation type would point -indirectly to a routine to perform this, so the relocation may be -performed on a byte being written to a 68k COFF file, even though 68k COFF -has no such relocation type. - -@item line numbers -Object formats can contain, for debugging purposes, some form of mapping -between symbols, source line numbers, and addresses in the output file. -These addresses have to be relocated along with the symbol information. -Each symbol with an associated list of line number records points to the -first record of the list. The head of a line number list consists of a -pointer to the symbol, which allows finding out the address of the -function whose line number is being described. The rest of the list is -made up of pairs: offsets into the section and line numbers. Any format -which can simply derive this information can pass it successfully -between formats (COFF, IEEE and Oasys). -@end table diff --git a/contrib/gdb/bfd/doc/chew.c b/contrib/gdb/bfd/doc/chew.c deleted file mode 100644 index 5c04404..0000000 --- a/contrib/gdb/bfd/doc/chew.c +++ /dev/null @@ -1,1551 +0,0 @@ -/* chew - Copyright (C) 1990-1991 Free Software Foundation, Inc. - Contributed by steve chamberlain @cygnus - -This file is part of BFD, the Binary File Descriptor library. - -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.

Each FDR has a - list of procedure descriptors (PDR). The address in the FDR - is the absolute address of the first procedure. The address - in the first PDR gives the offset of that procedure relative - to the object file's base-address. The addresses in - subsequent PDRs specify each procedure's address relative to - the object file's base-address. To make things more juicy, - whenever the PROF bit in the PDR is set, the real entry point - of the procedure may be 16 bytes below what would normally be - the procedure's entry point. Instead, DEC came up with a - wicked scheme to create profiled libraries "on the fly": - instead of shipping a regular and a profiled version of each - library, they insert 16 bytes of unused space in front of - each procedure and set the "prof" bit in the PDR to indicate - that there is a gap there (this is done automagically by "as" - when option "-pg" is specified). Thus, normally, you link - against such a library and, except for lots of 16 byte gaps - between functions, things will behave as usual. However, - when invoking "ld" with option "-pg", it will fill those gaps - with code that calls mcount(). It then moves the function's - entry point down by 16 bytes, and out pops a binary that has - all functions profiled. - - NOTE: Neither FDRs nor PDRs are strictly sorted in memory - order. For example, when including header-files that - define functions, the FDRs follow behind the including - file, even though their code may have been generated at - a lower address. File coff-alpha.c from libbfd - illustrates this (use "odump -PFv" to look at a file's - FDR/PDR). Similarly, PDRs are sometimes out of order - as well. An example of this is OSF/1 v3.0 libc's - malloc.c. I'm not sure why this happens, but it could - be due to optimizations that reorder a function's - position within an object-file. - - Strategy: - - On the first call to this function, we build a table of FDRs - that is sorted by the base-address of the object-file the FDR - is referring to. Notice that each object-file may contain - code from multiple source files (e.g., due to code defined in - include files). Thus, for any given base-address, there may - be multiple FDRs (but this case is, fortunately, uncommon). - lookup(addr) guarantees to return the first FDR that applies - to address ADDR. Thus, after invoking lookup(), we have a - list of FDRs that may contain the PDR for ADDR. Next, we - walk through the PDRs of these FDRs and locate the one that - is closest to ADDR (i.e., for which the difference between - ADDR and the PDR's entry point is positive and minimal). - Once, the right FDR and PDR are located, we simply walk - through the line-number table to lookup the line-number that - best matches ADDR. Obviously, things could be sped up by - keeping a sorted list of PDRs instead of a sorted list of - FDRs. However, this would increase space requirements - considerably, which is undesirable. */ - external_pdr_size = debug_swap->external_pdr_size; - - /* Make offset relative to object file's start-address: */ - offset -= tab[i].base_addr; - /* Search FDR list starting at tab[i] for the PDR that best matches - OFFSET.

It is not necessary to write special routines for - these entry points when creating a new BFD back end, since - generic versions are provided. However, writing them can - speed up linking and make it use significantly less runtime - memory. - - The first routine creates a hash table used by the other - routines. The second routine adds the symbols from an object - file to the hash table. The third routine takes all the - object files and links them together to create the output - file. These routines are designed so that the linker proper - does not need to know anything about the symbols in the object - files that it is linking. The linker merely arranges the - sections as directed by the linker script and lets BFD handle - the details of symbols and relocs. - - The second routine and third routines are passed a pointer to - a <<struct bfd_link_info>> structure (defined in - <<bfdlink.h>>) which holds information relevant to the link, - including the linker hash table (which was created by the - first routine) and a set of callback functions to the linker - proper. - - The generic linker routines are in <<linker.c>>, and use the - header file <<genlink.h>>. As of this writing, the only back - ends which have implemented versions of these routines are - a.out (in <<aoutx.h>>) and ECOFF (in <<ecoff.c>>). The a.out - routines are used as examples throughout this section. - -@menu -@* Creating a Linker Hash Table:: -@* Adding Symbols to the Hash Table:: -@* Performing the Final Link:: -@end menu - -INODE -Creating a Linker Hash Table, Adding Symbols to the Hash Table, Linker Functions, Linker Functions -SUBSECTION - Creating a linker hash table - -@cindex _bfd_link_hash_table_create in target vector -@cindex target vector (_bfd_link_hash_table_create) - The linker routines must create a hash table, which must be - derived from <<struct bfd_link_hash_table>> described in - <<bfdlink.c>>. @xref{Hash Tables} for information on how to - create a derived hash table. This entry point is called using - the target vector of the linker output file. - - The <<_bfd_link_hash_table_create>> entry point must allocate - and initialize an instance of the desired hash table. If the - back end does not require any additional information to be - stored with the entries in the hash table, the entry point may - simply create a <<struct bfd_link_hash_table>>. Most likely, - however, some additional information will be needed. - - For example, with each entry in the hash table the a.out - linker keeps the index the symbol has in the final output file - (this index number is used so that when doing a relocateable - link the symbol index used in the output file can be quickly - filled in when copying over a reloc). The a.out linker code - defines the required structures and functions for a hash table - derived from <<struct bfd_link_hash_table>>. The a.out linker - hash table is created by the function - <<NAME(aout,link_hash_table_create)>>; it simply allocates - space for the hash table, initializes it, and returns a - pointer to it. - - When writing the linker routines for a new back end, you will - generally not know exactly which fields will be required until - you have finished. You should simply create a new hash table - which defines no additional fields, and then simply add fields - as they become necessary. - -INODE -Adding Symbols to the Hash Table, Performing the Final Link, Creating a Linker Hash Table, Linker Functions -SUBSECTION - Adding symbols to the hash table - -@cindex _bfd_link_add_symbols in target vector -@cindex target vector (_bfd_link_add_symbols) - The linker proper will call the <<_bfd_link_add_symbols>> - entry point for each object file or archive which is to be - linked (typically these are the files named on the command - line, but some may also come from the linker script). The - entry point is responsible for examining the file. For an - object file, BFD must add any relevant symbol information to - the hash table. For an archive, BFD must determine which - elements of the archive should be used and adding them to the - link. - - The a.out version of this entry point is - <<NAME(aout,link_add_symbols)>>. - -@menu -@* Differing file formats:: -@* Adding symbols from an object file:: -@* Adding symbols from an archive:: -@end menu - -INODE -Differing file formats, Adding symbols from an object file, Adding Symbols to the Hash Table, Adding Symbols to the Hash Table -SUBSUBSECTION - Differing file formats - - Normally all the files involved in a link will be of the same - format, but it is also possible to link together different - format object files, and the back end must support that. The - <<_bfd_link_add_symbols>> entry point is called via the target - vector of the file to be added. This has an important - consequence: the function may not assume that the hash table - is the type created by the corresponding - <<_bfd_link_hash_table_create>> vector. All the - <<_bfd_link_add_symbols>> function can assume about the hash - table is that it is derived from <<struct - bfd_link_hash_table>>. - - Sometimes the <<_bfd_link_add_symbols>> function must store - some information in the hash table entry to be used by the - <<_bfd_final_link>> function. In such a case the <<creator>> - field of the hash table must be checked to make sure that the - hash table was created by an object file of the same format. - - The <<_bfd_final_link>> routine must be prepared to handle a - hash entry without any extra information added by the - <<_bfd_link_add_symbols>> function. A hash entry without - extra information will also occur when the linker script - directs the linker to create a symbol. Note that, regardless - of how a hash table entry is added, all the fields will be - initialized to some sort of null value by the hash table entry - initialization function. - - See <<ecoff_link_add_externals>> for an example of how to - check the <<creator>> field before saving information (in this - case, the ECOFF external symbol debugging information) in a - hash table entry. - -INODE -Adding symbols from an object file, Adding symbols from an archive, Differing file formats, Adding Symbols to the Hash Table -SUBSUBSECTION - Adding symbols from an object file - - When the <<_bfd_link_add_symbols>> routine is passed an object - file, it must add all externally visible symbols in that - object file to the hash table. The actual work of adding the - symbol to the hash table is normally handled by the function - <<_bfd_generic_link_add_one_symbol>>. The - <<_bfd_link_add_symbols>> routine is responsible for reading - all the symbols from the object file and passing the correct - information to <<_bfd_generic_link_add_one_symbol>>. - - The <<_bfd_link_add_symbols>> routine should not use - <<bfd_canonicalize_symtab>> to read the symbols. The point of - providing this routine is to avoid the overhead of converting - the symbols into generic <<asymbol>> structures. - -@findex _bfd_generic_link_add_one_symbol - <<_bfd_generic_link_add_one_symbol>> handles the details of - combining common symbols, warning about multiple definitions, - and so forth. It takes arguments which describe the symbol to - add, notably symbol flags, a section, and an offset. The - symbol flags include such things as <<BSF_WEAK>> or - <<BSF_INDIRECT>>. The section is a section in the object - file, or something like <<bfd_und_section_ptr>> for an undefined - symbol or <<bfd_com_section_ptr>> for a common symbol. - - If the <<_bfd_final_link>> routine is also going to need to - read the symbol information, the <<_bfd_link_add_symbols>> - routine should save it somewhere attached to the object file - BFD. However, the information should only be saved if the - <<keep_memory>> field of the <<info>> argument is true, so - that the <<-no-keep-memory>> linker switch is effective. - - The a.out function which adds symbols from an object file is - <<aout_link_add_object_symbols>>, and most of the interesting - work is in <<aout_link_add_symbols>>. The latter saves - pointers to the hash tables entries created by - <<_bfd_generic_link_add_one_symbol>> indexed by symbol number, - so that the <<_bfd_final_link>> routine does not have to call - the hash table lookup routine to locate the entry. - -INODE -Adding symbols from an archive, , Adding symbols from an object file, Adding Symbols to the Hash Table -SUBSUBSECTION - Adding symbols from an archive - - When the <<_bfd_link_add_symbols>> routine is passed an - archive, it must look through the symbols defined by the - archive and decide which elements of the archive should be - included in the link. For each such element it must call the - <<add_archive_element>> linker callback, and it must add the - symbols from the object file to the linker hash table. - -@findex _bfd_generic_link_add_archive_symbols - In most cases the work of looking through the symbols in the - archive should be done by the - <<_bfd_generic_link_add_archive_symbols>> function.

If the element is to - be included, the <<add_archive_element>> linker callback - routine must be called with the element as an argument, and - the elements symbols must be added to the linker hash table - just as though the element had itself been passed to the - <<_bfd_link_add_symbols>> function. - - When the a.out <<_bfd_link_add_symbols>> function receives an - archive, it calls <<_bfd_generic_link_add_archive_symbols>> - passing <<aout_link_check_archive_element>> as the function - argument. <<aout_link_check_archive_element>> calls - <<aout_link_check_ar_symbols>>. If the latter decides to add - the element (an element is only added if it provides a real, - non-common, definition for a previously undefined or common - symbol) it calls the <<add_archive_element>> callback and then - <<aout_link_check_archive_element>> calls - <<aout_link_add_symbols>> to actually add the symbols to the - linker hash table. - - The ECOFF back end is unusual in that it does not normally - call <<_bfd_generic_link_add_archive_symbols>>, because ECOFF - archives already contain a hash table of symbols.

This type of <<link_order>> describes part of an - output section in terms of a section belonging to one of the - input files.

It - is possible that most of the externally visible symbols may be - written out when considering the symbols of each input file, - but it is still necessary to traverse the hash table since the - linker script may have defined some symbols that are not in - any of the input files. - - The <<strip>> field of the <<bfd_link_info>> structure - controls which symbols are written out. The possible values - are listed in <<bfdlink.h>>. If the value is <<strip_some>>, - then the <<keep_hash>> field of the <<bfd_link_info>> - structure is a hash table of symbols to keep; each symbol - should be looked up in this hash table, and only symbols which - are present should be included in the output file. - - If the <<strip>> field of the <<bfd_link_info>> structure - permits local symbols to be written out, the <<discard>> field - is used to further controls which local symbols are included - in the output file.

In fact, I really -have no idea what the point of the line you want to remove is. - -A typical COFF reloc subtracts the old value of the symbol and adds in -the new value to the location in the object file (if it's a pc -relative reloc it adds the difference between the symbol value and the -location). When relocating we need to preserve that property. - -BFD handles this by setting the addend to the negative of the old -value of the symbol. Unfortunately it handles common symbols in a -non-standard way (it doesn't subtract the old value) but that's a -different story (we can't change it without losing backward -compatibility with old object files) (coff-i386 does subtract the old -value, to be compatible with existing coff-i386 targets, like SCO). - -So everything works fine when not producing relocateable output. When -we are producing relocateable output, logically we should do exactly -what we do when not producing relocateable output. Therefore, your -patch is correct. In fact, it should probably always just set -reloc_entry->addend to 0 for all cases, since it is, in fact, going to -add the value into the object file. This won't hurt the COFF code, -which doesn't use the addend; I'm not sure what it will do to other -formats (the thing to check for would be whether any formats both use -the addend and set partial_inplace). - -When I wanted to make coff-i386 produce relocateable output, I ran -into the problem that you are running into: I wanted to remove that -line. Rather than risk it, I made the coff-i386 relocs use a special -function; it's coff_i386_reloc in coff-i386.c. The function -specifically adds the addend field into the object file, knowing that -bfd_install_relocation is not going to.

The output section structure can be - considered a filter for the input section: the output section - determines the vma of the output data and the name, but the - input section determines the offset into the output section of - the data to be written. - - E.g., to create a section "O", starting at 0x100, 0x123 long, - containing two subsections, "A" at offset 0x0 (i.e., at vma - 0x100) and "B" at offset 0x20 (i.e., at vma 0x120) the <<asection>> - structures would look like: - -| section name "A" -| output_offset 0x00 -| size 0x20 -| output_section -----------> section name "O" -| | vma 0x100 -| section name "B" | size 0x123 -| output_offset 0x20 | -| size 0x103 | -| output_section --------| - - -SUBSECTION - Link orders - - The data within a section is stored in a @dfn{link_order}. - These are much like the fixups in <<gas>>. The link_order - abstraction allows a section to grow and shrink within itself. - - A link_order knows how big it is, and which is the next - link_order and where the raw data for it is; it also points to - a list of relocations which apply to it. - - The link_order is used by the linker to perform relaxing on - final code. The compiler creates code which is as big as - necessary to make it work without relaxing, and the user can - select whether to relax. Sometimes relaxing takes a lot of - time. The linker runs around the relocations to see if any - are attached to data which can be shrunk, if so it does it on - a link_order by link_order basis. - -*/ - - -#include "bfd.h" -#include "sysdep.h" -#include "libbfd.h" - - -/* -DOCDD -INODE -typedef asection, section prototypes, Section Output, Sections -SUBSECTION - typedef asection - - Here is the section structure: - -CODE_FRAGMENT -. -.typedef struct sec -.{ -. {* The name of the section; the name isn't a copy, the pointer is -. the same as that passed to bfd_make_section. *} -. -.

BFD passes information - to applications though the <<asymbol>> structure. When the - application requests the symbol table, BFD reads the table in - the native form and translates parts of it into the internal - format. To maintain more than the information passed to - applications, some targets keep some information ``behind the - scenes'' in a structure only the particular back end knows - about. For example, the coff back end keeps the original - symbol table structure as well as the canonical structure when - a BFD is read in. On output, the coff back end can reconstruct - the output symbol table so that no information is lost, even - information unique to coff which BFD doesn't know or - understand. If a coff symbol table were read, but were written - through an a.out back end, all the coff specific information - would be lost. The symbol table of a BFD - is not necessarily read in until a canonicalize request is - made. Then the BFD back end fills in a table provided by the - application with pointers to the canonical information. To - output symbols, the application provides BFD with a table of - pointers to pointers to <<asymbol>>s. This allows applications - like the linker to output a symbol as it was read, since the ``behind - the scenes'' information will be still available. -@menu -@* Reading Symbols:: -@* Writing Symbols:: -@* Mini Symbols:: -@* typedef asymbol:: -@* symbol handling functions:: -@end menu - -INODE -Reading Symbols, Writing Symbols, Symbols, Symbols -SUBSECTION - Reading symbols - - There are two stages to reading a symbol table from a BFD: - allocating storage, and the actual reading process.

The application attaches a vector of - pointers to pointers to symbols to the BFD being written, and - fills in the symbol count. The close and cleanup code reads - through the table provided and performs all the necessary - operations. The BFD output code must always be provided with an - ``owned'' symbol: one which has come from another BFD, or one - which has been created using <<bfd_make_empty_symbol>>. Here is an - example showing the creation of a symbol table with only one element: - -| #include "bfd.h" -| main() -| { -| bfd *abfd; -| asymbol *ptrs[2]; -| asymbol *new; -| -| abfd = bfd_openw("foo","a.out-sunos-big"); -| bfd_set_format(abfd, bfd_object); -| new = bfd_make_empty_symbol(abfd); -| new->name = "dummy_symbol"; -| new->section = bfd_make_section_old_way(abfd, ".text"); -| new->flags = BSF_GLOBAL; -| new->value = 0x12345; -| -| ptrs[0] = new; -| ptrs[1] = (asymbol *)0; -| -| bfd_set_symtab(abfd, ptrs, 1); -| bfd_close(abfd); -| } -| -| ./makesym -| nm foo -| 00012345 A dummy_symbol - - Many formats cannot represent arbitary symbol information; for - instance, the <<a.out>> object format does not allow an - arbitary number of sections.

It will return a <<void *>> - pointer to a block of memory, a symbol count, and the size of - each symbol. The pointer is allocated using <<malloc>>, and - should be freed by the caller when it is no longer needed. - - The function <<bfd_minisymbol_to_symbol>> will take a pointer - to a minisymbol, and a pointer to a structure returned by - <<bfd_make_empty_symbol>>, and return a <<asymbol>> structure. - The return value may or may not be the same as the value from - <<bfd_make_empty_symbol>> which was passed in. - -*/ - - - -/* -DOCDD -INODE -typedef asymbol, symbol handling functions, Mini Symbols, Symbols - -*/ -/* -SUBSECTION - typedef asymbol - - An <<asymbol>> has the form: - -*/ - -/* -CODE_FRAGMENT - -. -.typedef struct symbol_cache_entry -.{ -. {* A pointer to the BFD which owns the symbol.
