The major idea - is to use shell scripts to generate everything. - * generic.em replaces ldtemplate. - * Other *.em files replace various *.c files. - A *.em file is a shell script that generates the corresponding - ld__*.c file that implements an emulation. This is usually - a straight 'cat' of a here-document, possibly with substitutions. - * Script files (*.sc) are places by *.sc-sh scripts. - Again, these are simple shell scripts that 'cat' - here-documents, usually with some substitutions. - The output a *.sc-sh is a script file. - * Each emulation is defined by a short shell script with - extension *.sh that specifies the emulation-specific - parameters (such as the name of the *.sh-sc and *.em - files to use). - * genscript.sh is the master shell script used to generate - an emulation. It is passed various argument, including - the name a the emulation-speciic *.sh file that it - "sources" to set variables to emulation-specifc parameters. - * config/mt-foo: Changed EMUL=GLDFOO_EMULATION_NAME - to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.) - * config/mh-foo: Rename LDEMULATION names as appropriate - (usually 'gldfoo' -> plain 'foo'). - * ldwrite.c: Fixed a typo in a comment. - * Makefile.in: Major changes. Removed some the sed - magic to converts scripts, since that is now handled - by genscripts.sh and the *.sc-sh scipt generators. - * config.h: Remove a bunch of macros defining emulations - and targets. This becomes one less file to edit when - adding emulations or targets. - * ldemul.h (struct ld_emulation_xfer_struct): Add - emulation_name and target_name fields. - * ldemul.c, ldemul.h: Define some default functions used - by most emulations (and remove from the *.em scripts). - * ldemul.c (ldemul_choose_target): Search the new - ld_emulations array using a loop (instead of a hardwired - nested if statement). - Define the ld_emulation from the automatically-geenrated - ldemul-list.h. This means you no longer have to edit ldemul.c - to add a new emulation. - * ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by - their expansions, since the former no longer exist. - * PORTING: A very rough first draft of a porting guide. - - * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment - to be terminated by a new-line (instead of requiring a semicolon). - -Mon Feb 10 16:21:02 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * ldexp.c, ldlang.c: added new idea "abs_output_section", removes - tests for NULL pointers all over the place. - * ldlang.c (lang_process): remember to relocate global symbols - *after* relaxing has done it stuff. - -Thu Feb 6 11:40:15 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * config/mt-coff-h8300: use EMUL like everything else - * ldlang.c: (print_padding_statement): print the right address. - * Makefile.in, config.h, ldemul.c: renamed h8300hds to h8300hms - - -Tue Feb 4 15:28:01 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * ldlex.l: Put pack -noinhibit-exec and -sort-common - * ldlang.c (print_data_statement): print the right address. - -Thu Jan 30 17:51:53 1992 Per Bothner (bothner at cygnus.com) - - * Makefile.in: The rule for testing ld by re-linking itself - via an intermediate -r link was moved to the ld1 rule - instead of the ld2 rule. This allows ld2 and ld3 to be identical, - which allows the bootstrap rule to work. - * ldctor.c (find_constructors): Don't create a constructor - list if it is already defined (as would happen if ld is - invoked by collect). - -Wed Jan 29 08:35:39 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * config/mh-sparc.h: now uses libgcc.a - * ldmain.c: quit using exit - * *sc: use *(COMMON) rather than [COMMON] - * ldlex.l, lexsup.c: much thinking moved from .l and put into .c, - to allow preprocessing of .l file. - * Makefile.in: New ldlex.l mangling - * ldexp.c (fold_binary): perform expressions with % and / in - integer. - * ldfile.c (open_a): open archives on VMS in a special way - - -Tue Jan 28 10:18:16 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * ldgram.y: map -M behave in the same way as -Map (sets file name - to be "-". - * ldsym.c, ldlang.c: remember that size of a section is dependent on - whether or not relaxing has been done. - * ldmain.c: don't open a map file if it doesn't have a name - * relax.c: all the brains have moved into bfd. - * ldwrite.c: ammend comment - -Fri Jan 24 14:23:46 1992 Steve Chamberlain (sac at rtl.cygnus.com) - - * Makefile.in: added relax, also made three stage go through a - partial link stage. - * relax.c : added - * config.h: if GNU960 defined, then default emulation mode is - GLD960 - * ldexp.h, ldexp.c: map to file hooks - * ldlang.c: map to file hooks - * ldgram.y: added -Map -relax - * ldlex.l: added -relax, -Map - * ldmain.c: open map file - * ldmisc.c: support for map file - * ldwrite.c: new relax magic - -Thu Dec 19 18:49:51 1991 John Gilmore (gnu at cygnus.com) - - * Makefile.in, config/tm-*.h: Clean up make output, only - pass DEFAULT_EMULATION to ldmain.c. - -Wed Dec 18 15:02:47 1991 Per Bothner (bothner at cygnus.com) - - * ldver.c: Bump to version 1.94. - -Tue Dec 10 04:07:23 1991 K.

Richard Pixley (rich at rtl.cygnus.com) - - * Makefile.in: punt "fundamental" mode because it breaks my emacs - macros. install using INSTALL_PROGRAM and INSTALL_DATA. remove - spaces following hyphens, bsd make can't cope. added - standards.text support and made it look like all the other - makefiles. - - * configure.in: configure now runs entirely in objdir so make file - existence checks against ${srcdir}. Mark this directory as - target dependent. - -Thu Dec 5 22:46:16 1991 K. Richard Pixley (rich at rtl.cygnus.com) - - * Makefile.in: idestdir and ddestdir go away.

-* The linker script operator DEFINED() will now yield 1 only for a symbol that - is defined before the statement where DEFINED is used. - -* The MIPS --embedded-relocs (used to embed relocations into binaries for - Embedded-PIC code) is deprecated and will be removed in a future release. - -* m32r Linux (ELF) support added by Renesas. - -* Improved linker's handling of unresolved symbols. The switch - --unresolved-symbols=<method> has been added to tell the linker when it - should report them and the switch --warn-unresolved-symbols has been added to - make reports be issued as warning messages rather than errors. - -Changes in 2.14: - -* Added support for Xtensa architecture. - -* Added --with-sysroot configure switch to specify a target system root, for - linking against a target filesystem image. - -* Added --accept-unknown-linker-format to restore old linker behaviour (pre - 2.14) of silently accepting and linking in any files in an unknown binary - file format. - -* Added --no-omagic to undo the effects of the -N option. - -* Support for Texas Instruments TMS320C4x and TMS320C3x series of - DSP's contributed by Michael Hayes and Svein E.

Warning: using this option may result in - non-sharable applications. - -* Support for -z combreloc in the ELF linker, which puts dynamic - relocations against the same symbol together, so that dynamic linker - can use an one-entry symbol lookup cache. - -* Support for ELF SHF_MERGE section merging, by Jakub Jelinek. - -Changes in version 2.11: - -* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs. - -* Support added for eliminating duplicate DWARF2 debug information by - having the compiler generate the information in sections called - .gnu.linkonce.wi.XXXX where XXXX is a checksum for the contents. The - linker then merges these sections together into the normal .debug_info - section. - -* The native ELF linker now searches the directories in DT_RUNPATH or - DT_RPATH of a shared library for shared libraries needed by it. - -* TI C54x support, by Timothy Wall. - -* Added command line switch --section-start to set the start address of any - specified section. - -* Added ability to emit full relocation information in linked executables, - enabled by --emit-relocs. Some post-linkage optimization tools need - this information in order to be able to correctly identify and perform - symbol relative addressing in the event of changes in section contents - (instructions being added or deleted, extending data sections, etc.) - -* Support for i860, by Jason Eckhardt (preliminary, alpha quality). - -* Support for CRIS (Axis Communications ETRAX series). - -* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff. - -Changes in version 2.10: - -* Added AT> to the linker script language to allow load-time allocation of - sections into regions. - -* Added garbage collection of unused sections, enabled by --gc-sections. - It does require a bit of backend support; currently implemented are - arm-elf, avr-elf, d10v-elf, fr30-elf, i386-elf, m32r-elf, m68k-elf, - mcore-elf, mips-elf, mn10300-elf, ppc-elf, sh-elf, sparc-elf, and v850-elf. - Others will ignore the option. - -* Added SORT to the linker script language to permit sorting sections by file - name or section name. - -* Added EXTERN to the linker script language as an equivalent to the -u - command-line option. - -* Added ASSERT to the linker script language. - -* Added EXCLUDE_FILE to the linker script language for further control over - wildcard file names. - -* Added -O option to optimize linker output (as of this writing, this only - affects ELF shared library generation). - -* The -e option now accepts a number as well as a symbol name. - -* Added --no-undefined option to disallow undefined symbols when creating a - shared library. - -* The linker now issues a warning, not an error, for an undefined symbol when - using -Bsymbolic; use the new --no-undefined option to get the old - behaviour. - -* Added --demangle and --no-demangle options. - -Changes in version 2.9: - -* Added SQUAD to the linker script language. - -* New option --no-warn-mismatch. - -* The MEMORY command now parses the attributes to determine where sections that - are not placed in a specific memory region are placed. - -Changes in version 2.8: - -* Linker scripts may now contain shell wildcard characters for file and section - names. - -* The linker now supports symbol versions in ELF. - -* The NOCROSSREFS command was added to the linker script language. - -* The LOADADDR expression was added to the linker script language. - -* MAX and MIN functions were added to the linker script language. - -* The OVERLAY construct was added to the linker script language. - -* New option --warn-section-align to warn when the address of an output section - changes due to alignment of an input section. - -* New options --filter/-F and --auxiliary/-f. - -Changes in version 2.7: - -* New option --cref to print out a cross reference table. - -* New option --wrap SYMBOL. - -* New option --no-whole-archive, to turn off the effect of --whole-archive. - -* Input sections assigned to the output section /DISCARD/ in the linker script - are not included in the output file. - -* The SunOS and ELF linkers now merge stabs debugging information which uses - the N_BINCL and N_EINCL stab types. This reduces the amount of debugging - information generated. - -Changes in version 2.6: - -* When an ELF section name is representable as a C identifier (this is not true -of most ELF section names), the linker will automatically define symbols -__start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the -beginning and the end of the section. This is used by glibc. - -* When an ELF section named .gnu.warning is encountered in an input file, the -contents of the section are displayed as an error message, and the section is -not copied into the output file. This is used by glibc. - -* When an ELF section named .gnu.warning.SYMBOL is encountered in an input -file, and the symbol SYMBOL is referenced by some object file, the contents of -the section are displayed as an error message. The section is not copied into -the output file, unless doing a relocatable or shared link. This is used by -glibc. - -* New options -split-by-reloc and -split-by-file. - -* The linker now supports linking PIC compiled code on SPARC SunOS. It can -also create SPARC SunOS shared libraries, and, like the native SunOS linker, -will do so whenever there is an undefined symbol in the link and neither the -e -nor the -r option was used. - -* The -rpath option may be used on SunOS to set the list of directories to be -searched at run time. This overrides the default of building the list from the --L options. - -* The COFF linker now combines debugging information for structs, unions, and -enums, so that even if the same type is defined in multiple input files it will -only be defined once in the output file. The --traditional-format switch will -prevent this optimization. - -Changes in version 2.5: - -* The linker now supports linking against SunOS shared libraries. It still can -not link SunOS PIC (Position Independent Code) files, so it can not be used to -generate shared libraries. - -* The linker now supports linking against ELF shared libraries for the i386 -(UnixWare) and SPARC (Solaris). It can also link ELF PIC files, and can be -used to generate shared libraries. Shared library generation is not well -tested; please report any problems encountered. The linker is now enabled for -Solaris again. - -* Eric Youngdale has contributed Linux support code, including linking against -Linux a.out shared libraries. The linker produces Linux QMAGIC binaries. - -* The ELF backend has been converted to the new linker code. To use the new -ELF linker, each particular target requires a relocation function. So far, -this function has been written for i386 (UnixWare), SPARC (Solaris) MIPS (Irix -5), and HPPA ELF targets. - -* The -( (--start-group) and -) (--end-group) options have been added to -support searching a group of archives as though they were a single archive. -This can also be used in a linker script, as GROUP ( files ). - -* When a file is named on the command line, and the linker does not recognize -it as an object file, the linker will now treat the file as a linker script -file. A linker script named in this way augments, but does not replace, the -default linker script. - -* The -warn-once option was added. It causes the linker to only warn once per -undefined symbol, rather than once per reference. - -* The COFF backend has been converted to the new linker code. As with ELF, to -use the new linker, each particular target requires a relocation function. So -far, this function has been written for the i386, m68k, a29k and SH targets. - -* The -V flag was made a synonym for -v, for SVR4 compatibility. The old -V -behaviour is available via --verbose. - -Changes in version 2.4: - -* New linker code, by Steve Chamberlain and Ian Taylor. For a.out and ecoff - formats (so far), this should result in considerable savings in time - and memory used while linking; slightly poorer performance than - before for formats not converted yet. - -* Command-line parsing is no longer done with flex. This means - oddball characters in filenames won't get treated as argument - separators. - -* HP-PA ELF support, by Jeff Law. (No SOM support yet.) - -* Mach i386 support, by David Mackenzie. - -* Irix 4 shared libraries are now supported (Irix 5 uses ELF, and ELF shared - libraries are not yet supported). - -* COFF shared libraries (as on SCO) should work as well. - -* The linker is disabled for Solaris. (Actually, it was in 2.3 also, I just - forgot to note it.) Some of their C library routines don't work when - statically linked, and the GNU linker doesn't support dynamic linking yet. - -Changes in version 2.3: - -* Weak symbols are now supported. - -* ELF support has been added. The linker has been bootstrapped on - UnixWare and Solaris. - -* Alpha OSF/1 support has been added (non dynamic linking only). - -Changes in version 2.2: - -* The `bfd' library has been updated to reduce a.out-format string - table size. The effect of this is that files linked from many input - files with duplicate symbols (`-g' debugging records, or identical - static symbols) should be much smaller. - -Changes in version 2.1: - -* The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented. - -* There is now support for writing ECOFF files, so ld and the - other utilities should work on Risc/Ultrix and Irix. - - -Local variables: -fill-column: 79 -End: diff --git a/contrib/binutils/ld/README b/contrib/binutils/ld/README deleted file mode 100644 index a953e42..0000000 --- a/contrib/binutils/ld/README +++ /dev/null @@ -1,67 +0,0 @@ - README for LD - -This is the GNU linker.

(For example, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.)

Usually the last step in -compiling a program is to run \fBld\fR. -.PP -\&\fBld\fR accepts Linker Command Language files written in -a superset of \s-1AT&T\s0's Link Editor Command Language syntax, -to provide explicit and total control over the linking process. -.PP -This man page does not describe the command language; see the -\&\fBld\fR entry in \f(CW\*(C`info\*(C'\fR, or the manual -ld: the \s-1GNU\s0 linker, for full details on the command language and -on other aspects of the \s-1GNU\s0 linker. -.PP -This version of \fBld\fR uses the general purpose \s-1BFD\s0 libraries -to operate on object files. This allows \fBld\fR to read, combine, and -write object files in many different formats\-\-\-for example, \s-1COFF\s0 or -\&\f(CW\*(C`a.out\*(C'\fR. Different formats may be linked together to produce any -available kind of object file. -.PP -Aside from its flexibility, the \s-1GNU\s0 linker is more helpful than other -linkers in providing diagnostic information. Many linkers abandon -execution immediately upon encountering an error; whenever possible, -\&\fBld\fR continues executing, allowing you to identify other errors -(or, in some cases, to get an output file in spite of the error). -.PP -The \s-1GNU\s0 linker \fBld\fR is meant to cover a broad range of situations, -and to be as compatible as possible with other linkers. As a result, -you have many choices to control its behavior. -.SH "OPTIONS" -.IX Header "OPTIONS" -The linker supports a plethora of command-line options, but in actual -practice few of them are used in any particular context. -For instance, a frequent use of \fBld\fR is to link standard Unix -object files on a standard, supported Unix system. On such a system, to -link a file \f(CW\*(C`hello.o\*(C'\fR: -.PP -.Vb 1 -\& ld -o <output> /lib/crt0.o hello.o -lc -.Ve -.PP -This tells \fBld\fR to produce a file called \fIoutput\fR as the -result of linking the file \f(CW\*(C`/lib/crt0.o\*(C'\fR with \f(CW\*(C`hello.o\*(C'\fR and -the library \f(CW\*(C`libc.a\*(C'\fR, which will come from the standard search -directories. (See the discussion of the \fB\-l\fR option below.) -.PP -Some of the command-line options to \fBld\fR may be specified at any -point in the command line. However, options which refer to files, such -as \fB\-l\fR or \fB\-T\fR, cause the file to be read at the point at -which the option appears in the command line, relative to the object -files and other file options. Repeating non-file options with a -different argument will either have no further effect, or override prior -occurrences (those further to the left on the command line) of that -option. Options which may be meaningfully specified more than once are -noted in the descriptions below. -.PP -Non-option arguments are object files or archives which are to be linked -together. They may follow, precede, or be mixed in with command-line -options, except that an object file argument may not be placed between -an option and its argument. -.PP -Usually the linker is invoked with at least one object file, but you can -specify other forms of binary input files using \fB\-l\fR, \fB\-R\fR, -and the script command language. If \fIno\fR binary input files at all -are specified, the linker does not produce any output, and issues the -message \fBNo input files\fR. -.PP -If the linker cannot recognize the format of an object file, it will -assume that it is a linker script.

On such a system, to -link a file @code{hello.o}: - -@smallexample -ld -o @var{output} /lib/crt0.o hello.o -lc -@end smallexample - -This tells @command{ld} to produce a file called @var{output} as the -result of linking the file @code{/lib/crt0.o} with @code{hello.o} and -the library @code{libc.a}, which will come from the standard search -directories. (See the discussion of the @samp{-l} option below.) - -Some of the command-line options to @command{ld} may be specified at any -point in the command line. However, options which refer to files, such -as @samp{-l} or @samp{-T}, cause the file to be read at the point at -which the option appears in the command line, relative to the object -files and other file options. Repeating non-file options with a -different argument will either have no further effect, or override prior -occurrences (those further to the left on the command line) of that -option. Options which may be meaningfully specified more than once are -noted in the descriptions below. - -@cindex object files -Non-option arguments are object files or archives which are to be linked -together. They may follow, precede, or be mixed in with command-line -options, except that an object file argument may not be placed between -an option and its argument. - -Usually the linker is invoked with at least one object file, but you can -specify other forms of binary input files using @samp{-l}, @samp{-R}, -and the script command language. If @emph{no} binary input files at all -are specified, the linker does not produce any output, and issues the -message @samp{No input files}. - -If the linker cannot recognize the format of an object file, it will -assume that it is a linker script. A script specified in this way -augments the main linker script used for the link (either the default -linker script or the one specified by using @samp{-T}). This feature -permits the linker to link against a file which appears to be an object -or an archive, but actually merely defines some symbol values, or uses -@code{INPUT} or @code{GROUP} to load other objects. Note that -specifying a script in this way merely augments the main linker script; -use the @samp{-T} option to replace the default linker script entirely. -@xref{Scripts}. - -For options whose names are a single letter, -option arguments must either follow the option letter without intervening -whitespace, or be given as separate arguments immediately following the -option that requires them. - -For options whose names are multiple letters, either one dash or two can -precede the option name; for example, @samp{-trace-symbol} and -@samp{--trace-symbol} are equivalent. Note---there is one exception to -this rule. Multiple letter options that start with a lower case 'o' can -only be preceeded by two dashes. This is to reduce confusion with the -@samp{-o} option. So for example @samp{-omagic} sets the output file -name to @samp{magic} whereas @samp{--omagic} sets the NMAGIC flag on the -output. - -Arguments to multiple-letter options must either be separated from the -option name by an equals sign, or be given as separate arguments -immediately following the option that requires them. For example, -@samp{--trace-symbol foo} and @samp{--trace-symbol=foo} are equivalent. -Unique abbreviations of the names of multiple-letter options are -accepted. - -Note---if the linker is being invoked indirectly, via a compiler driver -(e.g. @samp{gcc}) then all the linker command line options should be -prefixed by @samp{-Wl,} (or whatever is appropriate for the particular -compiler driver) like this: - -@smallexample - gcc -Wl,--startgroup foo.o bar.o -Wl,--endgroup -@end smallexample - -This is important, because otherwise the compiler driver program may -silently drop the linker options, resulting in a bad link. - -Here is a table of the generic command line switches accepted by the GNU -linker: - -@table @gcctabopt -@kindex -a@var{keyword} -@item -a@var{keyword} -This option is supported for HP/UX compatibility. The @var{keyword} -argument must be one of the strings @samp{archive}, @samp{shared}, or -@samp{default}. @samp{-aarchive} is functionally equivalent to -@samp{-Bstatic}, and the other two keywords are functionally equivalent -to @samp{-Bdynamic}.

Even when @command{ld} is -configured to support alternative object formats, you don't usually need -to specify this, as @command{ld} should be configured to expect as a -default input format the most usual format on each machine. -@var{input-format} is a text string, the name of a particular format -supported by the BFD libraries.

The output -file and each input file are in a special data format known as an -@dfn{object file format}. Each file is called an @dfn{object file}. -The output file is often called an @dfn{executable}, but for our -purposes we will also call it an object file. Each object file has, -among other things, a list of @dfn{sections}. We sometimes refer to a -section in an input file as an @dfn{input section}; similarly, a section -in the output file is an @dfn{output section}. - -Each section in an object file has a name and a size. Most sections -also have an associated block of data, known as the @dfn{section -contents}. A section may be marked as @dfn{loadable}, which mean that -the contents should be loaded into memory when the output file is run. -A section with no contents may be @dfn{allocatable}, which means that an -area in memory should be set aside, but nothing in particular should be -loaded there (in some cases this memory must be zeroed out). A section -which is neither loadable nor allocatable typically contains some sort -of debugging information. - -Every loadable or allocatable output section has two addresses. The -first is the @dfn{VMA}, or virtual memory address. This is the address -the section will have when the output file is run. The second is the -@dfn{LMA}, or load memory address. This is the address at which the -section will be loaded. In most cases the two addresses will be the -same. An example of when they might be different is when a data section -is loaded into ROM, and then copied into RAM when the program starts up -(this technique is often used to initialize global variables in a ROM -based system). In this case the ROM address would be the LMA, and the -RAM address would be the VMA. - -You can see the sections in an object file by using the @code{objdump} -program with the @samp{-h} option. - -Every object file also has a list of @dfn{symbols}, known as the -@dfn{symbol table}. A symbol may be defined or undefined. Each symbol -has a name, and each defined symbol has an address, among other -information. If you compile a C or C++ program into an object file, you -will get a defined symbol for every defined function and global or -static variable. Every undefined function or global variable which is -referenced in the input file will become an undefined symbol. - -You can see the symbols in an object file by using the @code{nm} -program, or by using the @code{objdump} program with the @samp{-t} -option. - -@node Script Format -@section Linker Script Format -@cindex linker script format -Linker scripts are text files. - -You write a linker script as a series of commands. Each command is -either a keyword, possibly followed by arguments, or an assignment to a -symbol. You may separate commands using semicolons. Whitespace is -generally ignored. - -Strings such as file or format names can normally be entered directly. -If the file name contains a character such as a comma which would -otherwise serve to separate file names, you may put the file name in -double quotes. There is no way to use a double quote character in a -file name. - -You may include comments in linker scripts just as in C, delimited by -@samp{/*} and @samp{*/}. As in C, comments are syntactically equivalent -to whitespace. - -@node Simple Example -@section Simple Linker Script Example -@cindex linker script example -@cindex example of linker script -Many linker scripts are fairly simple. - -The simplest possible linker script has just one command: -@samp{SECTIONS}. You use the @samp{SECTIONS} command to describe the -memory layout of the output file. - -The @samp{SECTIONS} command is a powerful command. Here we will -describe a simple use of it. Let's assume your program consists only of -code, initialized data, and uninitialized data. These will be in the -@samp{.text}, @samp{.data}, and @samp{.bss} sections, respectively. -Let's assume further that these are the only sections which appear in -your input files. - -For this example, let's say that the code should be loaded at address -0x10000, and that the data should start at address 0x8000000. Here is a -linker script which will do that: -@smallexample -SECTIONS -@{ - . = 0x10000; - .text : @{ *(.text) @} - . = 0x8000000; - .data : @{ *(.data) @} - .bss : @{ *(.bss) @} -@} -@end smallexample - -You write the @samp{SECTIONS} command as the keyword @samp{SECTIONS}, -followed by a series of symbol assignments and output section -descriptions enclosed in curly braces. - -The first line inside the @samp{SECTIONS} command of the above example -sets the value of the special symbol @samp{.}, which is the location -counter. If you do not specify the address of an output section in some -other way (other ways are described later), the address is set from the -current value of the location counter. The location counter is then -incremented by the size of the output section. At the start of the -@samp{SECTIONS} command, the location counter has the value @samp{0}. - -The second line defines an output section, @samp{.text}. The colon is -required syntax which may be ignored for now. Within the curly braces -after the output section name, you list the names of the input sections -which should be placed into this output section. The @samp{*} is a -wildcard which matches any file name. The expression @samp{*(.text)} -means all @samp{.text} input sections in all input files. - -Since the location counter is @samp{0x10000} when the output section -@samp{.text} is defined, the linker will set the address of the -@samp{.text} section in the output file to be @samp{0x10000}. - -The remaining lines define the @samp{.data} and @samp{.bss} sections in -the output file. The linker will place the @samp{.data} output section -at address @samp{0x8000000}. After the linker places the @samp{.data} -output section, the value of the location counter will be -@samp{0x8000000} plus the size of the @samp{.data} output section. The -effect is that the linker will place the @samp{.bss} output section -immediately after the @samp{.data} output section in memory - -The linker will ensure that each output section has the required -alignment, by increasing the location counter if necessary. In this -example, the specified addresses for the @samp{.text} and @samp{.data} -sections will probably satisfy any alignment constraints, but the linker -may have to create a small gap between the @samp{.data} and @samp{.bss} -sections. - -That's it!

Thus at runtime, the dynamic -loader can make a quick check to make sure that the libraries you have -linked against do in fact supply all of the version nodes that the -application will need to resolve all of the dynamic symbols. In this -way it is possible for the dynamic linker to know with certainty that -all external symbols that it needs will be resolvable without having to -search for each symbol reference. - -The symbol versioning is in effect a much more sophisticated way of -doing minor version checking that SunOS does. The fundamental problem -that is being addressed here is that typically references to external -functions are bound on an as-needed basis, and are not all bound when -the application starts up. If a shared library is out of date, a -required interface may be missing; when the application tries to use -that interface, it may suddenly and unexpectedly fail. With symbol -versioning, the user will get a warning when they start their program if -the libraries being used with the application are too old. - -There are several GNU extensions to Sun's versioning approach. The -first of these is the ability to bind a symbol to a version node in the -source file where the symbol is defined instead of in the versioning -script. This was done mainly to reduce the burden on the library -maintainer. You can do this by putting something like: -@smallexample -__asm__(".symver original_foo,foo@@VERS_1.1"); -@end smallexample -@noindent -in the C source file. This renames the function @samp{original_foo} to -be an alias for @samp{foo} bound to the version node @samp{VERS_1.1}. -The @samp{local:} directive can be used to prevent the symbol -@samp{original_foo} from being exported. A @samp{.symver} directive -takes precedence over a version script. - -The second GNU extension is to allow multiple versions of the same -function to appear in a given shared library. In this way you can make -an incompatible change to an interface without increasing the major -version number of the shared library, while still allowing applications -linked against the old interface to continue to function. - -To do this, you must use multiple @samp{.symver} directives in the -source file. Here is an example: - -@smallexample -__asm__(".symver original_foo,foo@@"); -__asm__(".symver old_foo,foo@@VERS_1.1"); -__asm__(".symver old_foo1,foo@@VERS_1.2"); -__asm__(".symver new_foo,foo@@@@VERS_2.0"); -@end smallexample - -In this example, @samp{foo@@} represents the symbol @samp{foo} bound to the -unspecified base version of the symbol. The source file that contains this -example would define 4 C functions: @samp{original_foo}, @samp{old_foo}, -@samp{old_foo1}, and @samp{new_foo}. - -When you have multiple definitions of a given symbol, there needs to be -some way to specify a default version to which external references to -this symbol will be bound. You can do this with the -@samp{foo@@@@VERS_2.0} type of @samp{.symver} directive. You can only -declare one version of a symbol as the default in this manner; otherwise -you would effectively have multiple definitions of the same symbol. - -If you wish to bind a reference to a specific version of the symbol -within the shared library, you can use the aliases of convenience -(i.e., @samp{old_foo}), or you can use the @samp{.symver} directive to -specifically bind to an external version of the function in question. - -You can also specify the language in the version script: - -@smallexample -VERSION extern "lang" @{ version-script-commands @} -@end smallexample - -The supported @samp{lang}s are @samp{C}, @samp{C++}, and @samp{Java}. -The linker will iterate over the list of symbols at the link time and -demangle them according to @samp{lang} before matching them to the -patterns specified in @samp{version-script-commands}. - -@node Expressions -@section Expressions in Linker Scripts -@cindex expressions -@cindex arithmetic -The syntax for expressions in the linker script language is identical to -that of C expressions.

This is much faster and uses much less memory than does the -traditional import library method, expecially when linking large -libraries or applications. When @command{ld} creates an import lib, each -function or variable exported from the dll is stored in its own bfd, even -though a single bfd could contain many exports. The overhead involved in -storing, loading, and processing so many bfd's is quite large, and explains the -tremendous time, memory, and storage needed to link against particularly -large or complex libraries when using import libs. - -Linking directly to a dll uses no extra command-line switches other than -@samp{-L} and @samp{-l}, because @command{ld} already searches for a number -of names to match each library. All that is needed from the developer's -perspective is an understanding of this search, in order to force ld to -select the dll instead of an import library. - - -For instance, when ld is called with the argument @samp{-lxxx} it will attempt -to find, in the first directory of its search path, - -@example -libxxx.dll.a -xxx.dll.a -libxxx.a -cygxxx.dll (*) -libxxx.dll -xxx.dll -@end example - -before moving on to the next directory in the search path. - -(*) Actually, this is not @samp{cygxxx.dll} but in fact is @samp{<prefix>xxx.dll}, -where @samp{<prefix>} is set by the @command{ld} option -@samp{--dll-search-prefix=<prefix>}. In the case of cygwin, the standard gcc spec -file includes @samp{--dll-search-prefix=cyg}, so in effect we actually search for -@samp{cygxxx.dll}. - -Other win32-based unix environments, such as mingw or pw32, may use other -@samp{<prefix>}es, although at present only cygwin makes use of this feature. It -was originally intended to help avoid name conflicts among dll's built for the -various win32/un*x environments, so that (for example) two versions of a zlib dll -could coexist on the same machine. - -The generic cygwin/mingw path layout uses a @samp{bin} directory for -applications and dll's and a @samp{lib} directory for the import -libraries (using cygwin nomenclature): - -@example -bin/ - cygxxx.dll -lib/ - libxxx.dll.a (in case of dll's) - libxxx.a (in case of static archive) -@end example - -Linking directly to a dll without using the import library can be -done two ways: - -1. Use the dll directly by adding the @samp{bin} path to the link line -@example -gcc -Wl,-verbose -o a.exe -L../bin/ -lxxx -@end example - -However, as the dll's often have version numbers appended to their names -(@samp{cygncurses-5.dll}) this will often fail, unless one specifies -@samp{-L../bin -lncurses-5} to include the version. Import libs are generally -not versioned, and do not have this difficulty. - -2. Create a symbolic link from the dll to a file in the @samp{lib} -directory according to the above mentioned search pattern. This -should be used to avoid unwanted changes in the tools needed for -making the app/dll. - -@example -ln -s bin/cygxxx.dll lib/[cyg|lib|]xxx.dll[.a] -@end example - -Then you can link without any make environment changes. - -@example -gcc -Wl,-verbose -o a.exe -L../lib/ -lxxx -@end example - -This technique also avoids the version number problems, because the following is -perfectly legal - -@example -bin/ - cygxxx-5.dll -lib/ - libxxx.dll.a -> ../bin/cygxxx-5.dll -@end example - -Linking directly to a dll without using an import lib will work -even when auto-import features are exercised, and even when -@samp{--enable-runtime-pseudo-relocs} is used. - -Given the improvements in speed and memory usage, one might justifiably -wonder why import libraries are used at all. There are two reasons: - -1. Until recently, the link-directly-to-dll functionality did @emph{not} -work with auto-imported data. - -2. Sometimes it is necessary to include pure static objects within the -import library (which otherwise contains only bfd's for indirection -symbols that point to the exports of a dll). Again, the import lib -for the cygwin kernel makes use of this ability, and it is not -possible to do this without an import lib. - -So, import libs are not going away. But the ability to replace -true import libs with a simple symbolic link to (or a copy of) -a dll, in most cases, is a useful addition to the suite of tools -binutils makes available to the win32 developer. Given the -massive improvements in memory requirements during linking, storage -requirements, and linking speed, we expect that many developers -will soon begin to use this feature whenever possible. - -@item symbol aliasing -@table @emph -@item adding additional names -Sometimes, it is useful to export symbols with additional names. -A symbol @samp{foo} will be exported as @samp{foo}, but it can also be -exported as @samp{_foo} by using special directives in the DEF file -when creating the dll. This will affect also the optional created -import library. Consider the following DEF file: - -@example -LIBRARY "xyz.dll" BASE=0x61000000 - -EXPORTS -foo -_foo = foo -@end example - -The line @samp{_foo = foo} maps the symbol @samp{foo} to @samp{_foo}. - -Another method for creating a symbol alias is to create it in the -source code using the "weak" attribute: - -@example -void foo () @{ /* Do something. */; @} -void _foo () __attribute__ ((weak, alias ("foo"))); -@end example - -See the gcc manual for more information about attributes and weak -symbols. - -@item renaming symbols -Sometimes it is useful to rename exports. For instance, the cygwin -kernel does this regularly. A symbol @samp{_foo} can be exported as -@samp{foo} but not as @samp{_foo} by using special directives in the -DEF file. (This will also affect the import library, if it is -created). In the following example: - -@example -LIBRARY "xyz.dll" BASE=0x61000000 - -EXPORTS -_foo = foo -@end example - -The line @samp{_foo = foo} maps the exported symbol @samp{foo} to -@samp{_foo}. -@end table - -Note: using a DEF file disables the default auto-export behavior, -unless the @samp{--export-all-symbols} command line option is used. -If, however, you are trying to rename symbols, then you should list -@emph{all} desired exports in the DEF file, including the symbols -that are not being renamed, and do @emph{not} use the -@samp{--export-all-symbols} option. If you list only the -renamed symbols in the DEF file, and use @samp{--export-all-symbols} -to handle the other symbols, then the both the new names @emph{and} -the original names for the renamed symbols will be exported. -In effect, you'd be aliasing those symbols, not renaming them, -which is probably not what you wanted. -@end table - -@ifclear GENERIC -@lowersections -@end ifclear -@end ifset - -@ifset XTENSA -@ifclear GENERIC -@raisesections -@end ifclear - -@node Xtensa -@section @code{ld} and Xtensa Processors - -@cindex Xtensa processors -The default @command{ld} behavior for Xtensa processors is to interpret -@code{SECTIONS} commands so that lists of explicitly named sections in a -specification with a wildcard file will be interleaved when necessary to -keep literal pools within the range of PC-relative load offsets. For -example, with the command: - -@smallexample -SECTIONS -@{ - .text : @{ - *(.literal .text) - @} -@} -@end smallexample - -@noindent -@command{ld} may interleave some of the @code{.literal} -and @code{.text} sections from different object files to ensure that the -literal pools are within the range of PC-relative load offsets. A valid -interleaving might place the @code{.literal} sections from an initial -group of files followed by the @code{.text} sections of that group of -files. Then, the @code{.literal} sections from the rest of the files -and the @code{.text} sections from the rest of the files would follow. -The non-interleaved order can still be specified as: - -@smallexample -SECTIONS -@{ - .text : @{ - *(.literal) *(.text) - @} -@} -@end smallexample - -@cindex @code{--relax} on Xtensa -@cindex relaxing on Xtensa -@kindex --no-relax -The Xtensa version of @command{ld} enables the @option{--relax} option by -default to attempt to reduce space in the output image by combining -literals with identical values. It also provides the -@option{--no-relax} option to disable this optimization. When enabled, -the relaxation algorithm ensures that a literal will only be merged with -another literal when the new merged literal location is within the -offset range of all of its uses. - -The relaxation mechanism will also attempt to optimize -assembler-generated ``longcall'' sequences of -@code{L32R}/@code{CALLX@var{n}} when the target is known to fit into a -@code{CALL@var{n}} instruction encoding.

A different object file -format can be supported simply by creating a new BFD back end and adding -it to the library. To conserve runtime memory, however, the linker and -associated tools are usually configured to support only a subset of the -object file formats available.

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 a symbol 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 linker -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 generally most helpful to send the actual object files -provided that they are reasonably small. Say no more than 10K. For -bigger files you can either make them available by FTP or HTTP or else -state that you are willing to send the object file(s) to whomever -requests them. (Note - your email will be going to a mailing list, so -we do not want to clog it up with large attachments). But small -attachments are best. - -If the source files were assembled using @code{gas} or compiled using -@code{gcc}, then it may be OK to send the source files rather than the -object files. In this case, be sure to say exactly what version of -@code{gas} or @code{gcc} was used to produce the object files. Also say -how @code{gas} or @code{gcc} were configured. - -@item -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 @command{ld} gets a fatal signal, then we -will certainly notice it.

The emulation includes the -default linker script, and certain emulations also modify certain types -of linker behaviour. - -Emulations are created during the build process by the shell script -@file{genscripts.sh}. - -The @file{genscripts.sh} script starts by reading a file in the -@file{emulparams} directory. This is a shell script which sets various -shell variables used by @file{genscripts.sh} and the other shell scripts -it invokes. - -The @file{genscripts.sh} script will invoke a shell script in the -@file{scripttempl} directory in order to create default linker scripts -written in the linker command language. The @file{scripttempl} script -will be invoked 5 (or, in some cases, 6) times, with different -assignments to shell variables, to create different default scripts. -The choice of script is made based on the command line options. - -After creating the scripts, @file{genscripts.sh} will invoke yet another -shell script, this time in the @file{emultempl} directory. That shell -script will create the emulation source file, which contains C code. -This C code permits the linker emulation to override various linker -behaviours. Most targets use the generic emulation code, which is in -@file{emultempl/generic.em}. - -To summarize, @file{genscripts.sh} reads three shell scripts: an -emulation parameters script in the @file{emulparams} directory, a linker -script generation script in the @file{scripttempl} directory, and an -emulation source file generation script in the @file{emultempl} -directory. - -For example, the Sun 4 linker sets up variables in -@file{emulparams/sun4.sh}, creates linker scripts using -@file{scripttempl/aout.sc}, and creates the emulation code using -@file{emultempl/sunos.em}. - -Note that the linker can support several emulations simultaneously, -depending upon how it is configured. An emulation can be selected with -the @code{-m} option. The @code{-V} option will list all supported -emulations. - -@menu -* emulation parameters:: @file{emulparams} scripts -* linker scripts:: @file{scripttempl} scripts -* linker emulations:: @file{emultempl} scripts -@end menu - -@node emulation parameters -@section @file{emulparams} scripts - -Each target selects a particular file in the @file{emulparams} directory -by setting the shell variable @code{targ_emul} in @file{configure.tgt}. -This shell variable is used by the @file{configure} script to control -building an emulation source file. - -Certain conventions are enforced. Suppose the @code{targ_emul} variable -is set to @var{emul} in @file{configure.tgt}. The name of the emulation -shell script will be @file{emulparams/@var{emul}.sh}.

The linker script will use variable -substitutions, based on the above variables and those set in the -@file{emulparams} script, to control its behaviour. - -When there are parts of the @file{scripttempl} script which should only -be run when doing a final relocation, they should be enclosed within a -variable substitution based on @code{RELOCATING}. For example, on many -targets special symbols such as @code{_end} should be defined when doing -a final link. Naturally, those symbols should not be defined when doing -a relocatable link using @code{-r}. The @file{scripttempl} script -could use a construct like this to define those symbols: -@smallexample - $@{RELOCATING+ _end = .;@} -@end smallexample -This will do the symbol assignment only if the @code{RELOCATING} -variable is defined. - -The basic job of the linker script is to put the sections in the correct -order, and at the correct memory addresses. For some targets, the -linker script may have to do some other operations. - -For example, on most MIPS platforms, the linker is responsible for -defining the special symbol @code{_gp}, used to initialize the -@code{$gp} register. It must be set to the start of the small data -section plus @code{0x8000}. Naturally, it should only be defined when -doing a final relocation. This will typically be done like this: -@smallexample - $@{RELOCATING+ _gp = ALIGN(16) + 0x8000;@} -@end smallexample -This line would appear just before the sections which compose the small -data section (@samp{.sdata}, @samp{.sbss}). All those sections would be -contiguous in memory. - -Many COFF systems build constructor tables in the linker script. The -compiler will arrange to output the address of each global constructor -in a @samp{.ctor} section, and the address of each global destructor in -a @samp{.dtor} section (this is done by defining -@code{ASM_OUTPUT_CONSTRUCTOR} and @code{ASM_OUTPUT_DESTRUCTOR} in the -@code{gcc} configuration files). The @code{gcc} runtime support -routines expect the constructor table to be named @code{__CTOR_LIST__}. -They expect it to be a list of words, with the first word being the -count of the number of entries. There should be a trailing zero word. -(Actually, the count may be -1 if the trailing word is present, and the -trailing word may be omitted if the count is correct, but, as the -@code{gcc} behaviour has changed slightly over the years, it is safest -to provide both). Here is a typical way that might be handled in a -@file{scripttempl} file. -@smallexample - $@{CONSTRUCTING+ __CTOR_LIST__ = .;@} - $@{CONSTRUCTING+ LONG((__CTOR_END__ - __CTOR_LIST__) / 4 - 2)@} - $@{CONSTRUCTING+ *(.ctors)@} - $@{CONSTRUCTING+ LONG(0)@} - $@{CONSTRUCTING+ __CTOR_END__ = .;@} - $@{CONSTRUCTING+ __DTOR_LIST__ = .;@} - $@{CONSTRUCTING+ LONG((__DTOR_END__ - __DTOR_LIST__) / 4 - 2)@} - $@{CONSTRUCTING+ *(.dtors)@} - $@{CONSTRUCTING+ LONG(0)@} - $@{CONSTRUCTING+ __DTOR_END__ = .;@} -@end smallexample -The use of @code{CONSTRUCTING} ensures that these linker script commands -will only appear when the linker is supposed to be building the -constructor and destructor tables. This example is written for a target -which uses 4 byte pointers. - -Embedded systems often need to set a stack address. This is normally -best done by using the @code{PROVIDE} construct with a default stack -address. This permits the user to easily override the stack address -using the @code{--defsym} option. Here is an example: -@smallexample - $@{RELOCATING+ PROVIDE (__stack = 0x80000000);@} -@end smallexample -The value of the symbol @code{__stack} would then be used in the startup -code to initialize the stack pointer. - -@node linker emulations -@section @file{emultempl} scripts - -Each linker target uses an @file{emultempl} script to generate the -emulation code. The name of the @file{emultempl} script is set by the -@code{TEMPLATE_NAME} variable in the @file{emulparams} script. If the -@code{TEMPLATE_NAME} variable is not set, the default is -@samp{generic}. If the value of @code{TEMPLATE_NAME} is @var{template}, -@file{genscripts.sh} will use @file{emultempl/@var{template}.em}. - -Most targets use the generic @file{emultempl} script, -@file{emultempl/generic.em}. A different @file{emultempl} script is -only needed if the linker must support unusual actions, such as linking -against shared libraries. - -The @file{emultempl} script is normally written as a simple invocation -of @code{cat} with a here document. The document will use a few -variable substitutions. Typically each function names uses a -substitution involving @code{EMULATION_NAME}, for ease of debugging when -the linker supports multiple emulations. - -Every function and variable in the emitted file should be static. The -only globally visible object must be named -@code{ld_@var{EMULATION_NAME}_emulation}, where @var{EMULATION_NAME} is -the name of the emulation set in @file{configure.tgt} (this is also the -name of the @file{emulparams} file without the @file{.sh} extension). -The @file{genscripts.sh} script will set the shell variable -@code{EMULATION_NAME} before invoking the @file{emultempl} script. - -The @code{ld_@var{EMULATION_NAME}_emulation} variable must be a -@code{struct ld_emulation_xfer_struct}, as defined in @file{ldemul.h}. -It defines a set of function pointers which are invoked by the linker, -as well as strings for the emulation name (normally set from the shell -variable @code{EMULATION_NAME} and the default BFD target name (normally -set from the shell variable @code{OUTPUT_FORMAT} which is normally set -by the @file{emulparams} file). - -The @file{genscripts.sh} script will set the shell variable -@code{COMPILE_IN} when it invokes the @file{emultempl} script for the -default emulation. In this case, the @file{emultempl} script should -include the linker scripts directly, and return them from the -@code{get_scripts} entry point. When the emulation is not the default, -the @code{get_scripts} entry point should just return a file name. See -@file{emultempl/generic.em} for an example of how this is done. - -At some point, the linker emulation entry points should be documented. - -@node Emulation Walkthrough -@chapter A Walkthrough of a Typical Emulation - -This chapter is to help people who are new to the way emulations -interact with the linker, or who are suddenly thrust into the position -of having to work with existing emulations. It will discuss the files -you need to be aware of. It will tell you when the given "hooks" in -the emulation will be called. It will, hopefully, give you enough -information about when and how things happen that you'll be able to -get by. As always, the source is the definitive reference to this. - -The starting point for the linker is in @file{ldmain.c} where -@code{main} is defined. The bulk of the code that's emulation -specific will initially be in @code{emultempl/@var{emulation}.em} but -will end up in @code{e@var{emulation}.c} when the build is done. -Most of the work to select and interface with emulations is in -@code{ldemul.h} and @code{ldemul.c}. Specifically, @code{ldemul.h} -defines the @code{ld_emulation_xfer_struct} structure your emulation -exports. - -Your emulation file exports a symbol -@code{ld_@var{EMULATION_NAME}_emulation}. If your emulation is -selected (it usually is, since usually there's only one), -@code{ldemul.c} sets the variable @var{ld_emulation} to point to it. -@code{ldemul.c} also defines a number of API functions that interface -to your emulation, like @code{ldemul_after_parse} which simply calls -your @code{ld_@var{EMULATION}_emulation.after_parse} function. For -the rest of this section, the functions will be mentioned, but you -should assume the indirect reference to your emulation also. - -We will also skip or gloss over parts of the link process that don't -relate to emulations, like setting up internationalization. - -After initialization, @code{main} selects an emulation by pre-scanning -the command line arguments. It calls @code{ldemul_choose_target} to -choose a target. If you set @code{choose_target} to -@code{ldemul_default_target}, it picks your @code{target_name} by -default. - -@code{main} calls @code{ldemul_before_parse}, then @code{parse_args}. -@code{parse_args} calls @code{ldemul_parse_args} for each arg, which -must update the @code{getopt} globals if it recognizes the argument. -If the emulation doesn't recognize it, then parse_args checks to see -if it recognizes it. - -Now that the emulation has had access to all its command-line options, -@code{main} calls @code{ldemul_set_symbols}. This can be used for any -initialization that may be affected by options. It is also supposed -to set up any variables needed by the emulation script. - -@code{main} now calls @code{ldemul_get_script} to get the emulation -script to use (based on arguments, no doubt, @pxref{Emulations}) and -runs it. While parsing, @code{ldgram.y} may call @code{ldemul_hll} or -@code{ldemul_syslib} to handle the @code{HLL} or @code{SYSLIB} -commands. It may call @code{ldemul_unrecognized_file} if you asked -the linker to link a file it doesn't recognize. It will call -@code{ldemul_recognized_file} for each file it does recognize, in case -the emulation wants to handle some files specially. All the while, -it's loading the files (possibly calling -@code{ldemul_open_dynamic_archive}) and symbols and stuff. After it's -done reading the script, @code{main} calls @code{ldemul_after_parse}. -Use the after-parse hook to set up anything that depends on stuff the -script might have set up, like the entry point. - -@code{main} next calls @code{lang_process} in @code{ldlang.c}. This -appears to be the main core of the linking itself, as far as emulation -hooks are concerned(*). It first opens the output file's BFD, calling -@code{ldemul_set_output_arch}, and calls -@code{ldemul_create_output_section_statements} in case you need to use -other means to find or create object files (i.e. shared libraries -found on a path, or fake stub objects). Despite the name, nobody -creates output sections here. - -(*) In most cases, the BFD library does the bulk of the actual -linking, handling symbol tables, symbol resolution, relocations, and -building the final output file. See the BFD reference for all the -details. Your emulation is usually concerned more with managing -things at the file and section level, like "put this here, add this -section", etc. - -Next, the objects to be linked are opened and BFDs created for them, -and @code{ldemul_after_open} is called. At this point, you have all -the objects and symbols loaded, but none of the data has been placed -yet. - -Next comes the Big Linking Thingy (except for the parts BFD does). -All input sections are mapped to output sections according to the -script. If a section doesn't get mapped by default, -@code{ldemul_place_orphan} will get called to figure out where it goes. -Next it figures out the offsets for each section, calling -@code{ldemul_before_allocation} before and -@code{ldemul_after_allocation} after deciding where each input section -ends up in the output sections. - -The last part of @code{lang_process} is to figure out all the symbols' -values. After assigning final values to the symbols, -@code{ldemul_finish} is called, and after that, any undefined symbols -are turned into fatal errors. - -OK, back to @code{main}, which calls @code{ldwrite} in -@file{ldwrite.c}. @code{ldwrite} calls BFD's final_link, which does -all the relocation fixups and writes the output bfd to disk, and we're -done. - -In summary, - -@itemize @bullet - -@item @code{main()} in @file{ldmain.c} -@item @file{emultempl/@var{EMULATION}.em} has your code -@item @code{ldemul_choose_target} (defaults to your @code{target_name}) -@item @code{ldemul_before_parse} -@item Parse argv, calls @code{ldemul_parse_args} for each -@item @code{ldemul_set_symbols} -@item @code{ldemul_get_script} -@item parse script - -@itemize @bullet -@item may call @code{ldemul_hll} or @code{ldemul_syslib} -@item may call @code{ldemul_open_dynamic_archive} -@end itemize - -@item @code{ldemul_after_parse} -@item @code{lang_process()} in @file{ldlang.c} - -@itemize @bullet -@item create @code{output_bfd} -@item @code{ldemul_set_output_arch} -@item @code{ldemul_create_output_section_statements} -@item read objects, create input bfds - all symbols exist, but have no values -@item may call @code{ldemul_unrecognized_file} -@item will call @code{ldemul_recognized_file} -@item @code{ldemul_after_open} -@item map input sections to output sections -@item may call @code{ldemul_place_orphan} for remaining sections -@item @code{ldemul_before_allocation} -@item gives input sections offsets into output sections, places output sections -@item @code{ldemul_after_allocation} - section addresses valid -@item assigns values to symbols -@item @code{ldemul_finish} - symbol values valid -@end itemize - -@item output bfd is written to disk - -@end itemize - -@node Architecture Specific -@chapter Some Architecture Specific Notes - -This is the place for notes on the behavior of @code{ld} on -specific platforms.

Libraries of either -type may be mixed together. - -@item -Overhead (space): 8 bytes per imported symbol, plus 20 for each -reference to it; Overhead (load time): negligible; Overhead -(virtual/physical memory): should be less than effect of DLL -relocation. -@end enumerate - -Motivation - -The obvious and only way to get rid of dllimport insanity is -to make client access variable directly in the DLL, bypassing -the extra dereference imposed by ordinary DLL runtime linking. -I.e., whenever client contains someting like - -@code{mov dll_var,%eax,} - -address of dll_var in the command should be relocated to point -into loaded DLL. The aim is to make OS loader do so, and than -make ld help with that. Import section of PE made following -way: there's a vector of structures each describing imports -from particular DLL. Each such structure points to two other -parellel vectors: one holding imported names, and one which -will hold address of corresponding imported name. So, the -solution is de-vectorize these structures, making import -locations be sparse and pointing directly into code. - -Implementation - -For each reference of data symbol to be imported from DLL (to -set of which belong symbols with name <sym>, if __imp_<sym> is -found in implib), the import fixup entry is generated. That -entry is of type IMAGE_IMPORT_DESCRIPTOR and stored in .idata$3 -subsection. Each fixup entry contains pointer to symbol's address -within .text section (marked with __fuN_<sym> symbol, where N is -integer), pointer to DLL name (so, DLL name is referenced by -multiple entries), and pointer to symbol name thunk. Symbol name -thunk is singleton vector (__nm_th_<symbol>) pointing to -IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly containing -imported name. Here comes that "om the edge" problem mentioned above: -PE specification rambles that name vector (OriginalFirstThunk) should -run in parallel with addresses vector (FirstThunk), i.e. that they -should have same number of elements and terminated with zero. We violate -this, since FirstThunk points directly into machine code. But in -practice, OS loader implemented the sane way: it goes thru -OriginalFirstThunk and puts addresses to FirstThunk, not something -else. It once again should be noted that dll and symbol name -structures are reused across fixup entries and should be there -anyway to support standard import stuff, so sustained overhead is -20 bytes per reference. Other question is whether having several -IMAGE_IMPORT_DESCRIPTORS for the same DLL is possible. Answer is yes, -it is done even by native compiler/linker (libth32's functions are in -fact resident in windows9x kernel32.dll, so if you use it, you have -two IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is -whether referencing the same PE structures several times is valid. -The answer is why not, prohibiting that (detecting violation) would -require more work on behalf of loader than not doing it. - -@end table - -@node GNU Free Documentation License -@chapter GNU Free Documentation License - - GNU Free Documentation License - - Version 1.1, March 2000 - - Copyright (C) 2000 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - -0. PREAMBLE - -The purpose of this License is to make a manual, textbook, or other -written document "free" in the sense of freedom: to assure everyone -the effective freedom to copy and redistribute it, with or without -modifying it, either commercially or noncommercially. Secondarily, -this License preserves for the author and publisher a way to get -credit for their work, while not being considered responsible for -modifications made by others. - -This License is a kind of "copyleft", which means that derivative -works of the document must themselves be free in the same sense. It -complements the GNU General Public License, which is a copyleft -license designed for free software. - -We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. - - -1. APPLICABILITY AND DEFINITIONS - -This License applies to any manual or other work that contains a -notice placed by the copyright holder saying it can be distributed -under the terms of this License. The "Document", below, refers to any -such manual or work. Any member of the public is a licensee, and is -addressed as "you". - -A "Modified Version" of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A "Secondary Section" is a named appendix or a front-matter section of -the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall subject -(or to related matters) and contains nothing that could fall directly -within that overall subject. (For example, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The "Invariant Sections" are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. - -The "Cover Texts" are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. - -A "Transparent" copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, whose contents can be viewed and edited directly and -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup has been designed to thwart or discourage -subsequent modification by readers is not Transparent. A copy that is -not "Transparent" is called "Opaque". - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, LaTeX input format, SGML -or XML using a publicly available DTD, and standard-conforming simple -HTML designed for human modification. Opaque formats include -PostScript, PDF, proprietary formats that can be read and edited only -by proprietary word processors, SGML or XML for which the DTD and/or -processing tools are not generally available, and the -machine-generated HTML produced by some word processors for output -purposes only. - -The "Title Page" means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, "Title Page" means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - - -2. VERBATIM COPYING - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. - -You may also lend copies, under the same conditions stated above, and -you may publicly display copies. - - -3. COPYING IN QUANTITY - -If you publish printed copies of the Document numbering more than 100, -and the Document's license notice requires Cover Texts, you must enclose -the copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a publicly-accessible computer-network location containing a complete -Transparent copy of the Document, free of added material, which the -general network-using public has access to download anonymously at no -charge using public-standard network protocols. If you use the latter -option, you must take reasonably prudent steps, when you begin -distribution of Opaque copies in quantity, to ensure that this -Transparent copy will remain thus accessible at the stated location -until at least one year after the last time you distribute an Opaque -copy (directly or through your agents or retailers) of that edition to -the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - - -4. MODIFICATIONS - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: - -A. Use in the Title Page (and on the covers, if any) a title distinct - from that of the Document, and from those of previous versions - (which should, if there were any, be listed in the History section - of the Document). You may use the same title as a previous version - if the original publisher of that version gives permission. -B. List on the Title Page, as authors, one or more persons or entities - responsible for authorship of the modifications in the Modified - Version, together with at least five of the principal authors of the - Document (all of its principal authors, if it has less than five). -C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. -D. Preserve all the copyright notices of the Document. -E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. -F. Include, immediately after the copyright notices, a license notice - giving the public permission to use the Modified Version under the - terms of this License, in the form shown in the Addendum below. -G. Preserve in that license notice the full lists of Invariant Sections - and required Cover Texts given in the Document's license notice. -H. Include an unaltered copy of this License. -I. Preserve the section entitled "History", and its title, and add to - it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence. -J. Preserve the network location, if any, given in the Document for - public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions - it was based on. These may be placed in the "History" section. - You may omit a network location for a work that was published at - least four years before the Document itself, or if the original - publisher of the version it refers to gives permission. -K. In any section entitled "Acknowledgements" or "Dedications", - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements - and/or dedications given therein. -L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section titles. -M. Delete any section entitled "Endorsements". Such a section - may not be included in the Modified Version. -N. Do not retitle any existing section as "Endorsements" - or to conflict in title with any Invariant Section. - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section entitled "Endorsements", provided it contains -nothing but endorsements of your Modified Version by various -parties--for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - - -5. COMBINING DOCUMENTS - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. - -In the combination, you must combine any sections entitled "History" -in the various original documents, forming one section entitled -"History"; likewise combine any sections entitled "Acknowledgements", -and any sections entitled "Dedications". You must delete all sections -entitled "Endorsements." - - -6. COLLECTIONS OF DOCUMENTS - -You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. - -You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. - - -7. AGGREGATION WITH INDEPENDENT WORKS - -A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, does not as a whole count as a Modified Version -of the Document, provided no compilation copyright is claimed for the -compilation. Such a compilation is called an "aggregate", and this -License does not apply to the other self-contained works thus compiled -with the Document, on account of their being thus compiled, if they -are not themselves derivative works of the Document. - -If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one quarter -of the entire aggregate, the Document's Cover Texts may be placed on -covers that surround only the Document within the aggregate. -Otherwise they must appear on covers around the whole aggregate. - - -8. TRANSLATION - -Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License provided that you also include the -original English version of this License. In case of a disagreement -between the translation and the original English version of this -License, the original English version will prevail. - - -9. TERMINATION - -You may not copy, modify, sublicense, or distribute the Document except -as expressly provided for under this License. Any other attempt to -copy, modify, sublicense or distribute the Document 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. - - -10. FUTURE REVISIONS OF THIS LICENSE - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation 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. See -http://www.gnu.org/copyleft/. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License "or any later version" applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. - - -ADDENDUM: How to use this License for your documents - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and -license notices just after the title page: - -@smallexample - Copyright (c) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.1 - or any later version published by the Free Software Foundation; - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - A copy of the license is included in the section entitled "GNU - Free Documentation License". -@end smallexample - -If you have no Invariant Sections, write "with no Invariant Sections" -instead of saying which ones are invariant.

With this feature on, DLL clients can import variables from DLL - without any concern from their side (for example, without any source - code modifications). - - 2. This is done completely in bounds of the PE specification (to be fair, - there's a place where it pokes nose out of, but in practice it works). - So, resulting module can be used with any other PE compiler/linker. - - 3. Auto-import is fully compatible with standard import method and they - can be mixed together. - - 4. Overheads: space: 8 bytes per imported symbol, plus 20 for each - reference to it; load time: negligible; virtual/physical memory: should be - less than effect of DLL relocation, and I sincerely hope it doesn't affect - DLL sharability (too much). - - Idea - - The obvious and only way to get rid of dllimport insanity is to make client - access variable directly in the DLL, bypassing extra dereference. I.e., - whenever client contains something like - - mov dll_var,%eax, - - address of dll_var in the command should be relocated to point into loaded - DLL. The aim is to make OS loader do so, and than make ld help with that. - Import section of PE made following way: there's a vector of structures - each describing imports from particular DLL. Each such structure points - to two other parallel vectors: one holding imported names, and one which - will hold address of corresponding imported name. So, the solution is - de-vectorize these structures, making import locations be sparse and - pointing directly into code. Before continuing, it is worth a note that, - while authors strives to make PE act ELF-like, there're some other people - make ELF act PE-like: elfvector, ;-) . - - Implementation - - For each reference of data symbol to be imported from DLL (to set of which - belong symbols with name <sym>, if __imp_<sym> is found in implib), the - import fixup entry is generated. That entry is of type - IMAGE_IMPORT_DESCRIPTOR and stored in .idata$3 subsection. Each - fixup entry contains pointer to symbol's address within .text section - (marked with __fuN_<sym> symbol, where N is integer), pointer to DLL name - (so, DLL name is referenced by multiple entries), and pointer to symbol - name thunk. Symbol name thunk is singleton vector (__nm_th_<symbol>) - pointing to IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly - containing imported name. Here comes that "om the edge" problem mentioned - above: PE specification rambles that name vector (OriginalFirstThunk) - should run in parallel with addresses vector (FirstThunk), i.e. that they - should have same number of elements and terminated with zero. We violate - this, since FirstThunk points directly into machine code. But in practice, - OS loader implemented the sane way: it goes thru OriginalFirstThunk and - puts addresses to FirstThunk, not something else. It once again should be - noted that dll and symbol name structures are reused across fixup entries - and should be there anyway to support standard import stuff, so sustained - overhead is 20 bytes per reference. Other question is whether having several - IMAGE_IMPORT_DESCRIPTORS for the same DLL is possible. Answer is yes, it is - done even by native compiler/linker (libth32's functions are in fact reside - in windows9x kernel32.dll, so if you use it, you have two - IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is whether - referencing the same PE structures several times is valid. The answer is why - not, prohibiting that (detecting violation) would require more work on - behalf of loader than not doing it. - - See also: ld/emultempl/pe.em. */ - -static void add_bfd_to_link (bfd *, const char *, struct bfd_link_info *); - -/* For emultempl/pe.em. */ - -def_file * pe_def_file = 0; -int pe_dll_export_everything = 0; -int pe_dll_do_default_excludes = 1; -int pe_dll_kill_ats = 0; -int pe_dll_stdcall_aliases = 0; -int pe_dll_warn_dup_exports = 0; -int pe_dll_compat_implib = 0; -int pe_dll_extra_pe_debug = 0; - -/* Static variables and types. */ - -static bfd_vma image_base; -static bfd *filler_bfd; -static struct bfd_section *edata_s, *reloc_s; -static unsigned char *edata_d, *reloc_d; -static size_t edata_sz, reloc_sz; -static int runtime_pseudo_relocs_created = 0; - -typedef struct - { - char *target_name; - char *object_target; - unsigned int imagebase_reloc; - int pe_arch; - int bfd_arch; - int underscored; - } -pe_details_type; - -typedef struct - { - char *name; - int len; - } -autofilter_entry_type; - -#define PE_ARCH_i386 1 -#define PE_ARCH_sh 2 -#define PE_ARCH_mips 3 -#define PE_ARCH_arm 4 -#define PE_ARCH_arm_epoc 5 - -static pe_details_type pe_detail_list[] = -{ - { - "pei-i386", - "pe-i386", - 7 /* R_IMAGEBASE */, - PE_ARCH_i386, - bfd_arch_i386, - 1 - }, - { - "pei-shl", - "pe-shl", - 16 /* R_SH_IMAGEBASE */, - PE_ARCH_sh, - bfd_arch_sh, - 1 - }, - { - "pei-mips", - "pe-mips", - 34 /* MIPS_R_RVA */, - PE_ARCH_mips, - bfd_arch_mips, - 0 - }, - { - "pei-arm-little", - "pe-arm-little", - 11 /* ARM_RVA32 */, - PE_ARCH_arm, - bfd_arch_arm, - 1 - }, - { - "epoc-pei-arm-little", - "epoc-pe-arm-little", - 11 /* ARM_RVA32 */, - PE_ARCH_arm_epoc, - bfd_arch_arm, - 0 - }, - { NULL, NULL, 0, 0, 0, 0 } -}; - -static pe_details_type *pe_details; - -static autofilter_entry_type autofilter_symbollist[] = -{ - { "DllMain@12", 10 }, - { "DllEntryPoint@0", 15 }, - { "DllMainCRTStartup@12", 20 }, - { "_cygwin_dll_entry@12", 20 }, - { "_cygwin_crt0_common@8", 21 }, - { "_cygwin_noncygwin_dll_entry@12", 30 }, - { "impure_ptr", 10 }, - { "_pei386_runtime_relocator", 25 }, - { "do_pseudo_reloc", 15 }, - { "cygwin_crt0", 11 }, - { NULL, 0 } -}; - -/* Do not specify library suffix explicitly, to allow for dllized versions. */ -static autofilter_entry_type autofilter_liblist[] = -{ - { "libcygwin", 9 }, - { "libgcc", 6 }, - { "libstdc++", 9 }, - { "libmingw32", 10 }, - { "libmingwex", 10 }, - { "libg2c", 6 }, - { "libsupc++", 9 }, - { "libobjc", 7 }, - { "libgcj", 6 }, - { NULL, 0 } -}; - -static autofilter_entry_type autofilter_objlist[] = -{ - { "crt0.o", 6 }, - { "crt1.o", 6 }, - { "crt2.o", 6 }, - { "dllcrt1.o", 9 }, - { "dllcrt2.o", 9 }, - { "gcrt0.o", 7 }, - { "gcrt1.o", 7 }, - { "gcrt2.o", 7 }, - { "crtbegin.o", 10 }, - { "crtend.o", 8 }, - { NULL, 0 } -}; - -static autofilter_entry_type autofilter_symbolprefixlist[] = -{ - /* { "__imp_", 6 }, */ - /* Do __imp_ explicitly to save time. */ - { "__rtti_", 7 }, - /* Don't re-export auto-imported symbols. */ - { "_nm_", 4 }, - { "__builtin_", 10 }, - /* Don't export symbols specifying internal DLL layout. */ - { "_head_", 6 }, - { "_fmode", 6 }, - { "_impure_ptr", 11 }, - { "cygwin_attach_dll", 17 }, - { "cygwin_premain0", 15 }, - { "cygwin_premain1", 15 }, - { "cygwin_premain2", 15 }, - { "cygwin_premain3", 15 }, - { "environ", 7 }, - { NULL, 0 } -}; - -static autofilter_entry_type autofilter_symbolsuffixlist[] = -{ - { "_iname", 6 }, - { NULL, 0 } -}; - -#define U(str) (pe_details->underscored ?
