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. Added copyrights - and shift gpl to v2.

One of them checked for an existing - duplicate, the other didn't. Unfortunately, the latter - was called after the former ... - So, factor out code for inserting a new element into - constructor_name_list (after checking for a duplicate) - into a new function add_constructor_name, and call - it from both aforementioned places (ldlang_add_constructor - and ldlang_check_for_constructors). - -Wed Nov 13 15:17:43 1991 Per Bothner (bothner at cygnus.com) - - * Makefile.in: Rename .c files generated from ldtemplate - to have names starting with ld__.

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.

The section is not copied into -the output file, unless doing a relocateable 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 libaries. - -* The linker now supports linking against ELF shared libraries for the i386 -(UnixWare) and SPARC (Solaris).

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.

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.

Often the last step in -building a new compiled program to run is a call to \c -.B ld\c -\&. - -\c -.B ld\c -\& accepts Linker Command Language files -to provide explicit and total control over the linking process. -This man page does not describe the command language; see the `\|\c -.B ld\c -\|' entry in `\|\c -.B info\c -\|', or the manual -.I -ld: the GNU linker -\&, for full details on the command language and on other aspects of -the GNU linker. - -This version of \c -.B ld\c -\& uses the general purpose BFD libraries -to operate on object files. This allows \c -.B ld\c -\& to read, combine, and -write object files in many different formats\(em\&for example, COFF or -\c -.B a.out\c -\&. Different formats may be linked together to produce any -available kind of object file. You can use `\|\c -.B objdump \-i\c -\|' to get a list of formats supported on various architectures; see -.BR objdump ( 1 ). - -Aside from its flexibility, the GNU linker is more helpful than other -linkers in providing diagnostic information. Many linkers abandon -execution immediately upon encountering an error; whenever possible, -\c -.B ld\c -\& continues executing, allowing you to identify other errors -(or, in some cases, to get an output file in spite of the error). - -The GNU linker \c -.B ld\c -\& 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 through the command line, -and through environment variables. - -.SH OPTIONS -The plethora of command-line options may seem intimidating, but in -actual practice few of them are used in any particular context. -For instance, a frequent use of \c -.B ld\c -\& is to link standard Unix -object files on a standard, supported Unix system. On such a system, to -link a file \c -.B hello.o\c -\&: -.sp -.br -$\ ld\ \-o\ output\ /lib/crt0.o\ hello.o\ \-lc -.br -.sp -This tells \c -.B ld\c -\& to produce a file called \c -.B output\c -\& as the -result of linking the file \c -.B /lib/crt0.o\c -\& with \c -.B hello.o\c -\& and -the library \c -.B libc.a\c -\& which will come from the standard search -directories. - -The command-line options to \c -.B ld\c -\& may be specified in any order, and -may be repeated at will. For the most part, repeating an option with a -different argument will either have no further effect, or override prior -occurrences (those further to the left on the command line) of an -option. - -The exceptions\(em\&which may meaningfully be used more than once\(em\&are -\c -.B \-A\c -\&, \c -.B \-b\c -\& (or its synonym \c -.B \-format\c -\&), \c -.B \-defsym\c -\&, -\c -.B \-L\c -\&, \c -.B \-l\c -\&, \c -.B \-R\c -\&, and \c -.B \-u\c -\&. - -The list of object files to be linked together, shown as \c -.I objfile\c -\&, -may follow, precede, or be mixed in with command-line options; save that -an \c -.I objfile\c -\& argument may not be placed between an option flag and -its argument. - -Usually the linker is invoked with at least one object file, but other -forms of binary input files can also be specified with \c -.B \-l\c -\&, -\c -.B \-R\c -\&, and the script command language. If \c -.I no\c -\& binary input -files at all are specified, the linker does not produce any output, and -issues the message `\|\c -.B No input files\c -\|'. - -Option arguments must either follow the option letter without intervening -whitespace, or be given as separate arguments immediately following the -option that requires them. - -.TP -.BI "-A" "architecture" -In the current release of \c -.B ld\c -\&, this option is useful only for the -Intel 960 family of architectures. In that \c -.B ld\c -\& configuration, the -\c -.I architecture\c -\& argument is one of the two-letter names identifying -members of the 960 family; the option specifies the desired output -target, and warns of any incompatible instructions in the input files. -It also modifies the linker's search strategy for archive libraries, to -support the use of libraries specific to each particular -architecture, by including in the search loop names suffixed with the -string identifying the architecture. - -For example, if your \c -.B ld\c -\& command line included `\|\c -.B \-ACA\c -\|' as -well as `\|\c -.B \-ltry\c -\|', the linker would look (in its built-in search -paths, and in any paths you specify with \c -.B \-L\c -\&) for a library with -the names -.sp -.br -try -.br -libtry.a -.br -tryca -.br -libtryca.a -.br -.sp - -The first two possibilities would be considered in any event; the last -two are due to the use of `\|\c -.B \-ACA\c -\|'. - -Future releases of \c -.B ld\c -\& may support similar functionality for -other architecture families. - -You can meaningfully use \c -.B \-A\c -\& more than once on a command line, if -an architecture family allows combination of target architectures; each -use will add another pair of name variants to search for when \c -.B \-l -specifies a library. - -.TP -.BI "\-b " "input-format" -Specify the binary format for input object files that follow this option -on the command line. You don't usually need to specify this, as -\c -.B ld\c -\& is configured to expect as a default input format the most -usual format on each machine. \c -.I input-format\c -\& is a text string, the -name of a particular format supported by the BFD libraries. -\c -.B \-format \c -.I input-format\c -\&\c -\& has the same effect, as does the script command -.BR TARGET . - -You may want to use this option if you are linking files with an unusual -binary format. You can also use \c -.B \-b\c -\& to switch formats explicitly (when -linking object files of different formats), by including -\c -.B \-b \c -.I input-format\c -\&\c -\& before each group of object files in a -particular format. - -The default format is taken from the environment variable -.B GNUTARGET\c -\&. You can also define the input -format from a script, using the command \c -.B TARGET\c -\&. - -.TP -.B \-Bstatic -Do not link against shared libraries. This is only meaningful on -platforms for which shared libraries are supported. - -.TP -.B \-Bdynamic -Link against dynamic libraries. This is only meaningful on platforms -for which shared libraries are supported. This option is normally the -default on such platforms. - -.TP -.B \-Bsymbolic -When creating a shared library, bind references to global symbols to -the definition within the shared library, if any. Normally, it is -possible for a program linked against a shared library to override the -definition within the shared library. This option is only meaningful -on ELF platforms which support shared libraries. - -.TP -.BI "\-c " "commandfile" -Directs \c -.B ld\c -\& to read link commands from the file -\c -.I commandfile\c -\&. These commands will completely override \c -.B ld\c -\&'s -default link format (rather than adding to it); \c -.I commandfile\c -\& must -specify everything necessary to describe the target format. - - -You may also include a script of link commands directly in the command -line by bracketing it between `\|\c -.B {\c -\|' and `\|\c -.B }\c -\|' characters. - -.TP -.B \-\-cref -Output a cross reference table. If a linker map file is being -generated, the cross reference table is printed to the map file. -Otherwise, it is printed on the standard output. - -.TP -.B \-d -.TP -.B \-dc -.TP -.B \-dp -These three options are equivalent; multiple forms are supported for -compatibility with other linkers. Use any of them to make \c -.B ld -assign space to common symbols even if a relocatable output file is -specified (\c -.B \-r\c -\&). The script command -\c -.B FORCE_COMMON_ALLOCATION\c -\& has the same effect. - -.TP -.BI "-defsym " "symbol" "\fR = \fP" expression -Create a global symbol in the output file, containing the absolute -address given by \c -.I expression\c -\&. You may use this option as many -times as necessary to define multiple symbols in the command line. A -limited form of arithmetic is supported for the \c -.I expression\c -\& in this -context: you may give a hexadecimal constant or the name of an existing -symbol, or use \c -.B +\c -\& and \c -.B \-\c -\& to add or subtract hexadecimal -constants or symbols. If you need more elaborate expressions, consider -using the linker command language from a script. - -.TP -.B \-\-demangle -.TP -.B \-\-no\-demangle -These options control whether to demangle symbol names in error -messages and other output. When the linker is told to demangle, it -tries to present symbol names in a readable fashion: it strips leading -underscores if they are used by the object file format, and converts -C++ mangled symbol names into user readable names. The linker will -demangle by default unless the environment variable -.B COLLECT_NO_DEMANGLE -is set. These options may be used to override the default. - -.TP -.BI "-e " "entry"\c -\& -Use \c -.I entry\c -\& as the explicit symbol for beginning execution of your -program, rather than the default entry point. See the `\|\c -.B ld\c -\|' entry in `\|\c -.B info\c -\|' for a -discussion of defaults and other ways of specifying the -entry point. - -.TP -.B \-embedded\-relocs -This option is only meaningful when linking MIPS embedded PIC code, -generated by the -.B \-membedded\-pic -option to the GNU compiler and assembler. It causes the linker to -create a table which may be used at runtime to relocate any data which -was statically initialized to pointer values. See the code in -testsuite/ld-empic for details. - -.TP -.B \-E -.TP -.B \-export\-dynamic -When creating an ELF file, add all symbols to the dynamic symbol table. -Normally, the dynamic symbol table contains only symbols which are used -by a dynamic object. This option is needed for some uses of -.I dlopen. - -.TP -.BI "-f " "name" -.TP -.BI "--auxiliary " "name" -When creating an ELF shared object, set the internal DT_AUXILIARY field -to the specified name. This tells the dynamic linker that the symbol -table of the shared object should be used as an auxiliary filter on the -symbol table of the shared object -.I name. - -.TP -.BI "-F " "name" -.TP -.BI "--filter " "name" -When creating an ELF shared object, set the internal DT_FILTER field to -the specified name. This tells the dynamic linker that the symbol table -of the shared object should be used as a filter on the symbol table of -the shared object -.I name. - -.TP -.BI "\-format " "input\-format" -Synonym for \c -.B \-b\c -\& \c -.I input\-format\c -\&. - -.TP -.B \-g -Accepted, but ignored; provided for compatibility with other tools. - -.TP -.BI "\-G " "size"\c -Set the maximum size of objects to be optimized using the GP register -to -.I size -under MIPS ECOFF. Ignored for other object file formats. - -.TP -.BI "-h " "name" -.TP -.BI "-soname " "name" -When creating an ELF shared object, set the internal DT_SONAME field to -the specified name. When an executable is linked with a shared object -which has a DT_SONAME field, then when the executable is run the dynamic -linker will attempt to load the shared object specified by the DT_SONAME -field rather than the using the file name given to the linker. - -.TP -.B \-\-help -Print a summary of the command-line options on the standard output and exit. -This option and -.B \-\-version -begin with two dashes instead of one -for compatibility with other GNU programs. The other options start with -only one dash for compatibility with other linkers. - -.TP -.B \-i -Perform an incremental link (same as option \c -.B \-r\c -\&). - -.TP -.BI "\-l" "ar"\c -\& -Add an archive file \c -.I ar\c -\& to the list of files to link. This -option may be used any number of times. \c -.B ld\c -\& will search its -path-list for occurrences of \c -.B lib\c -.I ar\c -\&.a\c -\& for every \c -.I ar -specified. - -.TP -.BI "\-L" "searchdir" -This command adds path \c -.I searchdir\c -\& to the list of paths that -\c -.B ld\c -\& will search for archive libraries. You may use this option -any number of times. - -The default set of paths searched (without being specified with -\c -.B \-L\c -\&) depends on what emulation mode \c -.B ld\c -\& is using, and in -some cases also on how it was configured. The -paths can also be specified in a link script with the \c -.B SEARCH_DIR -command. - -.TP -.B \-M -Print (to the standard output file) a link map\(em\&diagnostic information -about where symbols are mapped by \c -.B ld\c -\&, and information on global -common storage allocation. - -.TP -.BI "\-Map " "mapfile"\c -Print to the file -.I mapfile -a link map\(em\&diagnostic information -about where symbols are mapped by \c -.B ld\c -\&, and information on global -common storage allocation. - -.TP -.BI "\-m " "emulation"\c -Emulate the -.I emulation -linker. You can list the available emulations with the -.I \-\-verbose -or -.I \-V -options. This option overrides the compiled-in default, which is the -system for which you configured -.BR ld . - -.TP -.B \-N -specifies readable and writable \c -.B text\c -\& and \c -.B data\c -\& sections. If -the output format supports Unix style magic numbers, the output is -marked as \c -.B OMAGIC\c -\&. - -When you use the `\|\c -.B \-N\c -\&\|' option, the linker does not page-align the -data segment. - -.TP -.B \-n -sets the text segment to be read only, and \c -.B NMAGIC\c -\& is written -if possible. - -.TP -.B \-noinhibit\-exec -Normally, the linker will not produce an output file if it encounters -errors during the link process. With this flag, you can specify that -you wish the output file retained even after non-fatal errors. - -.TP -.B \-no\-keep\-memory -The linker normally optimizes for speed over memory usage by caching -the symbol tables of input files in memory. This option tells the -linker to instead optimize for memory usage, by rereading the symbol -tables as necessary. This may be required if the linker runs out of -memory space while linking a large executable. - -.TP -.B \-no\-warn\-mismatch -Normally the linker will give an error if you try to link together -input files that are mismatched for some reason, perhaps because they -have been compiled for different processors or for different -endiannesses. This option tells the linker that it should silently -permit such possible errors. This option should only be used with -care, in cases when you have taken some special action that ensures -that the linker errors are inappropriate. - -.TP -.BI "\-o " "output" -.I output\c -\& is a name for the program produced by \c -.B ld\c -\&; if this -option is not specified, the name `\|\c -.B a.out\c -\|' is used by default. The -script command \c -.B OUTPUT\c -\& can also specify the output file name. - -.TP -.BI "\-O" "level" -Generate optimized output files. This might use significantly more -time and therefore probably should be enabled only for generating the -final binary. -\c -.I level\c -\& is supposed to be a numeric value. Any value greater than zero enables -the optimizations. - -.TP -.BI "\-oformat " "output\-format" -Specify the binary format for the output object file. -You don't usually need to specify this, as -\c -.B ld\c -\& is configured to produce as a default output format the most -usual format on each machine. \c -.I output-format\c -\& is a text string, the -name of a particular format supported by the BFD libraries. -The script command -.B OUTPUT_FORMAT -can also specify the output format, but this option overrides it. - -.TP -.BI "\-R " "filename" -Read symbol names and their addresses from \c -.I filename\c -\&, but do not -relocate it or include it in the output. This allows your output file -to refer symbolically to absolute locations of memory defined in other -programs. - -.TP -.B \-relax -An option with machine dependent effects. Currently this option is only -supported on the H8/300. - -On some platforms, use this option to perform global optimizations that -become possible when the linker resolves addressing in your program, such -as relaxing address modes and synthesizing new instructions in the -output object file. - -On platforms where this is not supported, `\|\c -.B \-relax\c -\&\|' is accepted, but has no effect. - -.TP -.B \-r -Generates relocatable output\(em\&i.e., generate an output file that can in -turn serve as input to \c -.B ld\c -\&. This is often called \c -.I partial -linking\c -\&. As a side effect, in environments that support standard Unix -magic numbers, this option also sets the output file's magic number to -\c -.B OMAGIC\c -\&. -If this option is not specified, an absolute file is produced. When -linking C++ programs, this option \c -.I will not\c -\& resolve references to -constructors; \c -.B \-Ur\c -\& is an alternative. - -This option does the same as \c -.B \-i\c -\&. - -.TP -.B \-rpath\ \fIdirectory -Add a directory to the runtime library search path. This is used when -linking an ELF executable with shared objects. All -.B \-rpath -arguments are concatenated and passed to the runtime linker, which uses -them to locate shared objects at runtime. The -.B \-rpath -option is also used when locating shared objects which are needed by -shared objects explicitly included in the link; see the description of -the -.B \-rpath\-link -option. If -.B \-rpath -is not used when linking an ELF executable, the contents of the -environment variable -.B LD_RUN_PATH -will be used if it is defined. - -The -.B \-rpath -option may also be used on SunOS. By default, on SunOS, the linker -will form a runtime search path out of all the -.B \-L -options it is given. If a -.B \-rpath -option is used, the runtime search path will be formed exclusively -using the -.B \-rpath -options, ignoring -the -.B \-L -options.

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 in the above example sets 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. - -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!

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.

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. - -@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.

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 -@file{Makefile} must have a target named @file{e@var{emul}.c}; this -target must depend upon @file{emulparams/@var{emul}.sh}, as well as the -appropriate scripts in the @file{scripttempl} and @file{emultempl} -directories. The @file{Makefile} target must invoke @code{GENSCRIPTS} -with two arguments: @var{emul}, and the value of the make variable -@code{tdir_@var{emul}}. The value of the latter variable will be set by -the @file{configure} script, and is used to set the default target -directory to search. - -By convention, the @file{emulparams/@var{emul}.sh} shell script should -only set shell variables. It may set shell variables which are to be -interpreted by the @file{scripttempl} and the @file{emultempl} scripts. -Certain shell variables are interpreted directly by the -@file{genscripts.sh} script. - -Here is a list of shell variables interpreted by @file{genscripts.sh}, -as well as some conventional shell variables interpreted by the -@file{scripttempl} and @file{emultempl} scripts. - -@table @code -@item SCRIPT_NAME -This is the name of the @file{scripttempl} script to use.

If -@code{TEMPLATE_NAME} is set to @var{template}, @file{genscripts.sh} will -use the script @file{emultempl/@var{template}.em}. If this variable is -not set, the default value is @samp{generic}. - -@item GENERATE_SHLIB_SCRIPT -If this is set to a nonempty string, @file{genscripts.sh} will invoke -the @file{scripttempl} script an extra time to create a shared library -script. @ref{linker scripts}. - -@item OUTPUT_FORMAT -This is normally set to indicate the BFD output format use (e.g., -@samp{"a.out-sunos-big"}.

The output has an extension of -@file{.xs}. -@end table - -Besides the shell variables set by the @file{emulparams} script, and the -@code{LD_FLAG} variable, the @file{genscripts.sh} script will set -certain variables for each run of the @file{scripttempl} script. - -@table @code -@item RELOCATING -This will be set to a non-empty string when the linker is doing a final -relocation (e.g., all scripts other than @code{-r} and @code{-Ur}). - -@item CONSTRUCTING -This will be set to a non-empty string when the linker is building -global constructor and destructor tables (e.g., all scripts other than -@code{-r}). - -@item DATA_ALIGNMENT -This will be set to an @code{ALIGN} expression when the output should be -page aligned, or to @samp{.} when generating the @code{-N} script. - -@item CREATE_SHLIB -This will be set to a non-empty string when generating a @code{-shared} -script. -@end table - -The conventional way to write a @file{scripttempl} script is to first -set a few shell variables, and then write out a linker script using -@code{cat} with a here document. 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 relocateable 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 - -@contents -@bye diff --git a/ld/ldlang.c b/ld/ldlang.c deleted file mode 100644 index e203b4791ee..00000000000 --- a/ld/ldlang.c +++ /dev/null @@ -1,4926 +0,0 @@ -/* Linker command language support. - Copyright (C) 1991, 92, 93, 94, 95, 96, 97, 98, 1999 - Free Software Foundation, Inc. - -This file is part of GLD, the Gnu Linker. - -GLD 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, or (at your option) -any later version. - -GLD 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.
