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.

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 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). 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/ld/README b/ld/README new file mode 100644 index 0000000..8947d04 --- /dev/null +++ b/ld/README @@ -0,0 +1,64 @@ +This is the GNU linker.

The GNU linker does not do this by default. This is +because the GNU linker tries to present the same interface for all +similar targets (in this case, all native ELF targets). This does not +matter for normal programs, but it can make a difference for programs +which try to dlopen an executable, such as PERL or Tcl. You can make +the GNU linker export all dynamic symbols with the -E or +--export-dynamic command line option. + +HP/UX 9.01 has a shell bug that causes the linker scripts to be +generated incorrectly. The symptom of this appears to be "fatal error +- scanner input buffer overflow" error messages. There are various +workarounds to this: + * Build and install bash, and build with "make SHELL=bash". + * Update to a version of HP/UX with a working shell (e.g., 9.05). + * Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in + genscripts.sh with "sh ${srcdir}..."

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. This can be useful when using gcc, which adds many +.B \-L +options which may be on NFS mounted filesystems. + +.TP +.B \-rpath\-link\ \fIdirectory +When using ELF or SunOS, one shared library may require another. This +happens when an +.B ld\ \-shared +link includes a shared library as one of the input files. + +When the linker encounters such a dependency when doing a non-shared, +non-relocateable link, it will automatically try to locate the required +shared library and include it in the link, if it is not included +explicitly. In such a case, the +.B \-rpath\-link +option specifies the first set of directories to search. The +.B \-rpath\-link +option may specify a sequence of directory names either by specifying +a list of names separated by colons, or by appearing multiple times. + +If the required shared library is not found, the linker will issue a +warning and continue with the link. + +.TP +.B \-S +Omits debugger symbol information (but not all symbols) from the output file. + +.TP +.B \-s +Omits all symbol information from the output file. + +.TP +.B \-shared +Create a shared library. This is currently only supported on ELF and +SunOS platforms (on SunOS it is not required, as the linker will +automatically create a shared library when there are undefined symbols +and the +.B \-e +option is not used). + +.TP +.B \-sort\-common +Normally, when +.B ld +places the global common symbols in the appropriate output sections, +it sorts them by size. First come all the one byte symbols, then all +the two bytes, then all the four bytes, and then everything else. +This is to prevent gaps between symbols due to +alignment constraints. This option disables that sorting. + +.TP +.B \-split\-by\-reloc\ \fIcount +Trys to creates extra sections in the output file so that no single +output section in the file contains more than +.I count +relocations. +This is useful when generating huge relocatable for downloading into +certain real time kernels with the COFF object file format; since COFF +cannot represent more than 65535 relocations in a single section. +Note that this will fail to work with object file formats which do not +support arbitrary sections. The linker will not split up individual +input sections for redistribution, so if a single input section +contains more than +.I count +relocations one output section will contain that many relocations. + +.TP +.B \-split\-by\-file +Similar to +.B \-split\-by\-reloc +but creates a new output section for each input file. + +.TP +.BI "\-Tbss " "org"\c +.TP +.BI "\-Tdata " "org"\c +.TP +.BI "\-Ttext " "org"\c +Use \c +.I org\c +\& as the starting address for\(em\&respectively\(em\&the +\c +.B bss\c +\&, \c +.B data\c +\&, or the \c +.B text\c +\& segment of the output file. +\c +.I org\c +\& must be a hexadecimal integer. + +.TP +.BI "\-T " "commandfile" +Equivalent to \c +.B \-c \c +.I commandfile\c +\&\c +\&; supported for compatibility with +other tools. + +.TP +.B \-t +Prints names of input files as \c +.B ld\c +\& processes them. + +.TP +.BI "\-u " "sym" +Forces \c +.I sym\c +\& to be entered in the output file as an undefined symbol. +This may, for example, trigger linking of additional modules from +standard libraries. \c +.B \-u\c +\& may be repeated with different option +arguments to enter additional undefined symbols. + +.TP +.B \-Ur +For anything other than C++ programs, this option is equivalent to +\c +.B \-r\c +\&: it generates relocatable output\(em\&i.e., an output file that can in +turn serve as input to \c +.B ld\c +\&. When linking C++ programs, \c +.B \-Ur +.I will\c +\& resolve references to constructors, unlike \c +.B \-r\c +\&. + +.TP +.B \-\-verbose +Display the version number for \c +.B ld +and list the supported emulations. +Display which input files can and can not be opened. + +.TP +.B \-v, \-V +Display the version number for \c +.B ld\c +\&. +The +.B \-V +option also lists the supported emulations. + +.TP +.B \-\-version +Display the version number for \c +.B ld +and exit. + +.TP +.B \-warn\-common +Warn when a common symbol is combined with another common symbol or with +a symbol definition. Unix linkers allow this somewhat sloppy practice, +but linkers on some other operating systems do not. This option allows +you to find potential problems from combining global symbols. + +.TP +.B \-warn\-constructors +Warn if any global constructors are used. This is only useful for a +few object file formats. For formats like COFF or ELF, the linker can +not detect the use of global constructors. + +.TP +.B \-warn\-multiple\-gp +Warn if the output file requires multiple global-pointer values. This +option is only meaningful for certain processors, such as the Alpha. + +.TP +.B \-warn\-once +Only warn once for each undefined symbol, rather than once per module +which refers to it. + +.TP +.B \-warn\-section\-align +Warn if the address of an output section is changed because of +alignment. Typically, the alignment will be set by an input section. +The address will only be changed if it not explicitly specified; that +is, if the SECTIONS command does not specify a start address for the +section. + +.TP +.B \-\-whole\-archive +For each archive mentioned on the command line after the +.B \-\-whole\-archive +option, include every object file in the archive in the link, rather +than searching the archive for the required object files. This is +normally used to turn an archive file into a shared library, forcing +every object to be included in the resulting shared library. + +.TP +.B \-\-no\-whole\-archive +Turn off the effect of the +.B \-\-whole\-archive +option for archives which appear later on the command line. + +.TP +.BI "--wrap " "symbol" +Use a wrapper function for +.I symbol. +Any undefined reference to +.I symbol +will be resolved to +.BI "__wrap_" "symbol". +Any undefined reference to +.BI "__real_" "symbol" +will be resolved to +.I symbol. + +.TP +.B \-X +Delete all temporary local symbols. For most targets, this is all local +symbols whose names begin with `\|\c +.B L\c +\|'. + +.TP +.B \-x +Delete all local symbols. + +.PP + +.SH ENVIRONMENT +\c +You can change the behavior of +.B ld\c +\& with the environment variable \c +.B GNUTARGET\c +\&. + +\c +.B GNUTARGET\c +\& determines the input-file object format if you don't +use \c +.B \-b\c +\& (or its synonym \c +.B \-format\c +\&).

Usually the last step in +compiling a program is to run @code{ld}. + +@code{ld} accepts Linker Command Language files written in +a superset of AT&T's Link Editor Command Language syntax, +to provide explicit and total control over the linking process. + +@ifclear SingleFormat +This version of @code{ld} uses the general purpose BFD libraries +to operate on object files. This allows @code{ld} to read, combine, and +write object files in many different formats---for example, COFF or +@code{a.out}. Different formats may be linked together to produce any +available kind of object file. @xref{BFD}, for more information. +@end ifclear + +Aside from its flexibility, the @sc{gnu} linker is more helpful than other +linkers in providing diagnostic information. Many linkers abandon +execution immediately upon encountering an error; whenever possible, +@code{ld} continues executing, allowing you to identify other errors +(or, in some cases, to get an output file in spite of the error). + +@node Invocation +@chapter Invocation + +The @sc{gnu} linker @code{ld} 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. + +@ifset UsesEnvVars +@menu +* Options:: Command Line Options +* Environment:: Environment Variables +@end menu + +@node Options +@section Command Line Options +@end ifset + +@cindex command line +@cindex options +The linker supports a plethora of command-line options, but in actual +practice few of them are used in any particular context. +@cindex standard Unix system +For instance, a frequent use of @code{ld} is to link standard Unix +object files on a standard, supported Unix system. 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 @code{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.) + +The command-line options to @code{ld} may be specified in any order, and +may be repeated at will. Repeating most 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 objects files 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 can not 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 should only be used to augment the main +linker script; if you want to use some command that logically can only +appear once, such as the @code{SECTIONS} or @code{MEMORY} command, you +must replace the default linker script using the @samp{-T} option. +@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{--oformat} and +@samp{--oformat} are equivalent. 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{--oformat srec} and +@samp{--oformat=srec} are equivalent. Unique abbreviations of the names +of multiple-letter options are accepted. + +@table @code +@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}. This option may be used any number of times. + +@ifset I960 +@cindex architectures +@kindex -A@var{arch} +@item -A@var{architecture} +@kindex --architecture=@var{arch} +@itemx --architecture=@var{architecture} +In the current release of @code{ld}, this option is useful only for the +Intel 960 family of architectures. In that @code{ld} configuration, the +@var{architecture} argument identifies the particular architecture in +the 960 family, enabling some safeguards and modifying the +archive-library search path. @xref{i960,,@code{ld} and the Intel 960 +family}, for details. + +Future releases of @code{ld} may support similar functionality for +other architecture families. +@end ifset + +@ifclear SingleFormat +@cindex binary input format +@kindex -b @var{format} +@kindex --format=@var{format} +@cindex input format +@cindex input format +@item -b @var{input-format} +@itemx --format=@var{input-format} +@code{ld} may be configured to support more than one kind of object +file. If your @code{ld} is configured this way, you can use the +@samp{-b} option to specify the binary format for input object files +that follow this option on the command line. Even when @code{ld} is +configured to support alternative object formats, you don't usually need +to specify this, as @code{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. (You can list the available binary +formats with @samp{objdump -i}.) +@xref{BFD}. + +You may want to use this option if you are linking files with an unusual +binary format. You can also use @samp{-b} to switch formats explicitly (when +linking object files of different formats), by including +@samp{-b @var{input-format}} before each group of object files in a +particular format. + +The default format is taken from the environment variable +@code{GNUTARGET}. +@ifset UsesEnvVars +@xref{Environment}. +@end ifset +You can also define the input format from a script, using the command +@code{TARGET}; see @ref{Format Commands}. +@end ifclear + +@kindex -c @var{MRI-cmdfile} +@kindex --mri-script=@var{MRI-cmdfile} +@cindex compatibility, MRI +@item -c @var{MRI-commandfile} +@itemx --mri-script=@var{MRI-commandfile} +For compatibility with linkers produced by MRI, @code{ld} accepts script +files written in an alternate, restricted command language, described in +@ref{MRI,,MRI Compatible Script Files}.

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 @var{name}. + +If you later link a program against this filter object, then, when you +run the program, the dynamic linker will see the DT_AUXILIARY field. If +the dynamic linker resolves any symbols from the filter object, it will +first check whether there is a definition in the shared object +@var{name}. If there is one, it will be used instead of the definition +in the filter object. The shared object @var{name} need not exist. +Thus the shared object @var{name} may be used to provide an alternative +implementation of certain functions, perhaps for debugging or for +machine specific performance. + +This option may be specified more than once.

The +dynamic linker will resolve symbols according to the symbol table of the +filter object as usual, but it will actually link to the definitions +found in the shared object @var{name}. Thus the filter object can be +used to select a subset of the symbols provided by the object +@var{name}. + +Some older linkers used the @code{-F} option throughout a compilation +toolchain for specifying object-file format for both input and output +object files. The @sc{gnu} linker uses other mechanisms for this +purpose: the @code{-b}, @code{--format}, @code{--oformat} options, the +@code{TARGET} command in linker scripts, and the @code{GNUTARGET} +environment variable.

Specifically, on ELF +and SunOS systems, @code{ld} will search a directory for a library with +an extension of @code{.so} before searching for one with an extension of +@code{.a}. By convention, a @code{.so} extension indicates a shared +library. + +The linker will search an archive only once, at the location where it is +specified on the command line. If the archive defines a symbol which +was undefined in some object which appeared before the archive on the +command line, the linker will include the appropriate file(s) from the +archive. However, an undefined symbol in an object appearing later on +the command line will not cause the linker to search the archive again. + +See the @code{-(} option for a way to force the linker to search +archives multiple times. + +You may list the same archive multiple times on the command line. + +@ifset GENERIC +This type of archive searching is standard for Unix linkers.

Most linker scripts do nothing +more than this. However, when necessary, the linker script can also +direct the linker to perform many other operations, using the commands +described below. + +The linker always uses a linker script. If you do not supply one +yourself, the linker will use a default script that is compiled into the +linker executable. You can use the @samp{--verbose} command line option +to display the default linker script. Certain command line options, +such as @samp{-r} or @samp{-N}, will affect the default linker script. + +You may supply your own linker script by using the @samp{-T} command +line option. When you do this, your linker script will replace the +default linker script. + +You may also use linker scripts implicitly by naming them as input files +to the linker, as though they were files to be linked. @xref{Implicit +Linker Scripts}. + +@menu +* Basic Script Concepts:: Basic Linker Script Concepts +* Script Format:: Linker Script Format +* Simple Example:: Simple Linker Script Example +* Simple Commands:: Simple Linker Script Commands +* Assignments:: Assigning Values to Symbols +* SECTIONS:: SECTIONS Command +* MEMORY:: MEMORY Command +* PHDRS:: PHDRS Command +* VERSION:: VERSION Command +* Expressions:: Expressions in Linker Scripts +* Implicit Linker Scripts:: Implicit Linker Scripts +@end menu + +@node Basic Script Concepts +@section Basic Linker Script Concepts +@cindex linker script concepts +We need to define some basic concepts and vocabulary in order to +describe the linker script language. + +The linker combines input files into a single output file. 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! That's a simple and complete linker script. + +@node Simple Commands +@section Simple Linker Script Commands +@cindex linker script simple commands +In this section we describe the simple linker script commands. + +@menu +* Entry Point:: Setting the entry point +* File Commands:: Commands dealing with files +@ifclear SingleFormat +* Format Commands:: Commands dealing with object file formats +@end ifclear + +* Miscellaneous Commands:: Other linker script commands +@end menu + +@node Entry Point +@subsection Setting the entry point +@kindex ENTRY(@var{symbol}) +@cindex start of execution +@cindex first instruction +@cindex entry point +The first instruction to execute in a program is called the @dfn{entry +point}.

If +it is not found, the linker will search through the archive library +search path. See the description of @samp{-L} in @ref{Options,,Command +Line Options}. + +If you use @samp{INPUT (-l@var{file})}, @code{ld} will transform the +name to @code{lib@var{file}.a}, as with the command line argument +@samp{-l}. + +When you use the @code{INPUT} command in an implicit linker script, the +files will be included in the link at the point at which the linker +script file is included.

If both are used, the command +line option takes precedence. + +You can use @code{OUTPUT_FORMAT} with three arguments to use different +formats based on the @samp{-EB} and @samp{-EL} command line options. +This permits the linker script to set the output format based on the +desired endianness. + +If neither @samp{-EB} nor @samp{-EL} are used, then the output format +will be the first argument, @var{default}. If @samp{-EB} is used, the +output format will be the second argument, @var{big}. If @samp{-EL} is +used, the output format will be the third argument, @var{little}. + +For example, the default linker script for the MIPS ELF target uses this +command: +@smallexample +OUTPUT_FORMAT(elf32-bigmips, elf32-bigmips, elf32-littlemips) +@end smallexample +This says that the default format for the output file is +@samp{elf32-bigmips}, but if the user uses the @samp{-EL} command line +option, the output file will be created in the @samp{elf32-littlemips} +format. + +@item TARGET(@var{bfdname}) +@kindex TARGET(@var{bfdname}) +@cindex input file format in linker script +The @code{TARGET} command names the BFD format to use when reading input +files.

In formats which only +support a limited number of sections, such as @code{a.out}, the name +must be one of the names supported by the format (@code{a.out}, for +example, allows only @samp{.text}, @samp{.data} or @samp{.bss}). If the +output format supports any number of sections, but with numbers and not +names (as is the case for Oasys), the name should be supplied as a +quoted numeric string.

If you provide neither @var{address} nor +@var{region}, then the address of the output section will be set to the +current value of the location counter aligned to the alignment +requirements of the output section. The alignment requirement of the +output section is the strictest alignment of any input section contained +within the output section. + +For example, +@smallexample +.text . : @{ *(.text) @} +@end smallexample +@noindent +and +@smallexample +.text : @{ *(.text) @} +@end smallexample +@noindent +are subtly different. The first will set the address of the +@samp{.text} output section to the current value of the location +counter. The second will set it to the current value of the location +counter aligned to the strictest alignment of a @samp{.text} input +section. + +The @var{address} may be an arbitrary expression; @ref{Expressions}. +For example, if you want to align the section on a 0x10 byte boundary, +so that the lowest four bits of the section address are zero, you could +do something like this: +@smallexample +.text ALIGN(0x10) : @{ *(.text) @} +@end smallexample +@noindent +This works because @code{ALIGN} returns the current location counter +aligned upward to the specified value. + +Specifying @var{address} for a section will change the value of the +location counter. + +@node Input Section +@subsection Input section description +@cindex input sections +@cindex mapping input sections to output sections +The most common output section command is an input section description. + +The input section description is the most basic linker script operation. +You use output sections to tell the linker how to lay out your program +in memory.

For example, to +include all input @samp{.text} sections, you would write: +@smallexample +*(.text) +@end smallexample +@noindent +Here the @samp{*} is a wildcard which matches any file name. To exclude a file +from matching the file name wildcard, EXCLUDE_FILE may be used to match all files +except the one specified by EXCLUDE_FILE. For example: +@smallexample +(*(EXCLUDE_FILE (*crtend.o) .ctors)) +@end smallexample +will cause all .ctors sections from all files except crtend.o to be included. + +There are two ways to include more than one section: +@smallexample +*(.text .rdata) +*(.text) *(.rdata) +@end smallexample +@noindent +The difference between these is the order in which the @samp{.text} and +@samp{.rdata} input sections will appear in the output section. In the +first example, they will be intermingled. In the second example, all +@samp{.text} input sections will appear first, followed by all +@samp{.rdata} input sections. + +You can specify a file name to include sections from a particular file. +You would do this if one or more of your files contain special data that +needs to be at a particular location in memory. For example: +@smallexample +data.o(.data) +@end smallexample + +If you use a file name without a list of sections, then all sections in +the input file will be included in the output section. This is not +commonly done, but it may by useful on occasion. For example: +@smallexample +data.o +@end smallexample + +When you use a file name which does not contain any wild card +characters, the linker will first see if you also specified the file +name on the linker command line or in an @code{INPUT} command. If you +did not, the linker will attempt to open the file as an input file, as +though it appeared on the command line. Note that this differs from an +@code{INPUT} command, because the linker will not search for the file in +the archive search path. + +@node Input Section Wildcards +@subsubsection Input section wildcard patterns +@cindex input section wildcards +@cindex wildcard file name patterns +@cindex file name wildcard patterns +@cindex section name wildcard patterns +In an input section description, either the file name or the section +name or both may be wildcard patterns. + +The file name of @samp{*} seen in many examples is a simple wildcard +pattern for the file name. + +The wildcard patterns are like those used by the Unix shell. + +@table @samp +@item * +matches any number of characters +@item ? +matches any single character +@item [@var{chars}] +matches a single instance of any of the @var{chars}; the @samp{-} +character may be used to specify a range of characters, as in +@samp{[a-z]} to match any lower case letter +@item \ +quotes the following character +@end table + +When a file name is matched with a wildcard, the wildcard characters +will not match a @samp{/} character (used to separate directory names on +Unix). A pattern consisting of a single @samp{*} character is an +exception; it will always match any file name, whether it contains a +@samp{/} or not. In a section name, the wildcard characters will match +a @samp{/} character. + +File name wildcard patterns only match files which are explicitly +specified on the command line or in an @code{INPUT} command. The linker +does not search directories to expand wildcards. + +If a file name matches more than one wildcard pattern, or if a file name +appears explicitly and is also matched by a wildcard pattern, the linker +will use the first match in the linker script. For example, this +sequence of input section descriptions is probably in error, because the +@file{data.o} rule will not be used: +@smallexample +.data : @{ *(.data) @} +.data1 : @{ data.o(.data) @} +@end smallexample + +@cindex SORT +Normally, the linker will place files and sections matched by wildcards +in the order in which they are seen during the link. You can change +this by using the @code{SORT} keyword, which appears before a wildcard +pattern in parentheses (e.g., @code{SORT(.text*)}). When the +@code{SORT} keyword is used, the linker will sort the files or sections +into ascending order by name before placing them in the output file. + +If you ever get confused about where input sections are going, use the +@samp{-M} linker option to generate a map file. The map file shows +precisely how input sections are mapped to output sections. + +This example shows how wildcard patterns might be used to partition +files. This linker script directs the linker to place all @samp{.text} +sections in @samp{.text} and all @samp{.bss} sections in @samp{.bss}. +The linker will place the @samp{.data} section from all files beginning +with an upper case character in @samp{.DATA}; for all other files, the +linker will place the @samp{.data} section in @samp{.data}. +@smallexample +@group +SECTIONS @{ + .text : @{ *(.text) @} + .DATA : @{ [A-Z]*(.data) @} + .data : @{ *(.data) @} + .bss : @{ *(.bss) @} +@} +@end group +@end smallexample + +@node Input Section Common +@subsubsection Input section for common symbols +@cindex common symbol placement +@cindex uninitialized data placement +A special notation is needed for common symbols, because in many object +file formats common symbols do not have a particular input section. The +linker treats common symbols as though they are in an input section +named @samp{COMMON}. + +You may use file names with the @samp{COMMON} section just as with any +other input sections. You can use this to place common symbols from a +particular input file in one section while common symbols from other +input files are placed in another section. + +In most cases, common symbols in input files will be placed in the +@samp{.bss} section in the output file. For example: +@smallexample +.bss @{ *(.bss) *(COMMON) @} +@end smallexample + +@cindex scommon section +@cindex small common symbols +Some object file formats have more than one type of common symbol. For +example, the MIPS ELF object file format distinguishes standard common +symbols and small common symbols. In this case, the linker will use a +different special section name for other types of common symbols. In +the case of MIPS ELF, the linker uses @samp{COMMON} for standard common +symbols and @samp{.scommon} for small common symbols. This permits you +to map the different types of common symbols into memory at different +locations. + +@cindex [COMMON] +You will sometimes see @samp{[COMMON]} in old linker scripts. This +notation is now considered obsolete. It is equivalent to +@samp{*(COMMON)}. + +@node Input Section Keep +@subsubsection Input section and garbage collection +@cindex KEEP +@cindex garbage collection +When link-time garbage collection is in use (@samp{--gc-sections}), +it is often useful to mark sections that should not be eliminated. +This is accomplished by surrounding an input section's wildcard entry +with @code{KEEP()}, as in @code{KEEP(*(.init))} or +@code{KEEP(SORT(*)(.ctors))}. + +@node Input Section Example +@subsubsection Input section example +The following example is a complete linker script.

All of section @samp{.input1} from file @file{foo.o} +follows immediately, in the same output section.

Each keyword is followed by an expression in +parentheses providing the value to store (@pxref{Expressions}). The +value of the expression is stored at the current value of the location +counter. + +The @code{BYTE}, @code{SHORT}, @code{LONG}, and @code{QUAD} commands +store one, two, four, and eight bytes (respectively). After storing the +bytes, the location counter is incremented by the number of bytes +stored. + +For example, this will store the byte 1 followed by the four byte value +of the symbol @samp{addr}: +@smallexample +BYTE(1) +LONG(addr) +@end smallexample + +When using a 64 bit host or target, @code{QUAD} and @code{SQUAD} are the +same; they both store an 8 byte, or 64 bit, value. When both host and +target are 32 bits, an expression is computed as 32 bits. In this case +@code{QUAD} stores a 32 bit value zero extended to 64 bits, and +@code{SQUAD} stores a 32 bit value sign extended to 64 bits. + +If the object file format of the output file has an explicit endianness, +which is the normal case, the value will be stored in that endianness. +When the object file format does not have an explicit endianness, as is +true of, for example, S-records, the value will be stored in the +endianness of the first input object file. + +@kindex FILL(@var{expression}) +@cindex holes, filling +@cindex unspecified memory +You may use the @code{FILL} command to set the fill pattern for the +current section. It is followed by an expression in parentheses. Any +otherwise unspecified regions of memory within the section (for example, +gaps left due to the required alignment of input sections) are filled +with the two least significant bytes of the expression, repeated as +necessary. A @code{FILL} statement covers memory locations after the +point at which it occurs in the section definition; by including more +than one @code{FILL} statement, you can have different fill patterns in +different parts of an output section. + +This example shows how to fill unspecified regions of memory with the +value @samp{0x9090}: +@smallexample +FILL(0x9090) +@end smallexample + +The @code{FILL} command is similar to the @samp{=@var{fillexp}} output +section attribute (@pxref{Output Section Fill}), but it only affects the +part of the section following the @code{FILL} command, rather than the +entire section. If both are used, the @code{FILL} command takes +precedence. + +@node Output Section Keywords +@subsection Output section keywords +There are a couple of keywords which can appear as output section +commands. + +@table @code +@kindex CREATE_OBJECT_SYMBOLS +@cindex input filename symbols +@cindex filename symbols +@item CREATE_OBJECT_SYMBOLS +The command tells the linker to create a symbol for each input file. +The name of each symbol will be the name of the corresponding input +file. The section of each symbol will be the output section in which +the @code{CREATE_OBJECT_SYMBOLS} command appears. + +This is conventional for the a.out object file format. It is not +normally used for any other object file format. + +@kindex CONSTRUCTORS +@cindex C++ constructors, arranging in link +@cindex constructors, arranging in link +@item CONSTRUCTORS +When linking using the a.out object file format, the linker uses an +unusual set construct to support C++ global constructors and +destructors. When linking object file formats which do not support +arbitrary sections, such as ECOFF and XCOFF, the linker will +automatically recognize C++ global constructors and destructors by name. +For these object file formats, the @code{CONSTRUCTORS} command tells the +linker to place constructor information in the output section where the +@code{CONSTRUCTORS} command appears. The @code{CONSTRUCTORS} command is +ignored for other object file formats. + +The symbol @w{@code{__CTOR_LIST__}} marks the start of the global +constructors, and the symbol @w{@code{__DTOR_LIST}} marks the end. The +first word in the list is the number of entries, followed by the address +of each constructor or destructor, followed by a zero word. The +compiler must arrange to actually run the code. For these object file +formats @sc{gnu} C++ normally calls constructors from a subroutine +@code{__main}; a call to @code{__main} is automatically inserted into +the startup code for @code{main}. @sc{gnu} C++ normally runs +destructors either by using @code{atexit}, or directly from the function +@code{exit}. + +For object file formats such as @code{COFF} or @code{ELF} which support +arbitrary section names, @sc{gnu} C++ will normally arrange to put the +addresses of global constructors and destructors into the @code{.ctors} +and @code{.dtors} sections. Placing the following sequence into your +linker script will build the sort of table which the @sc{gnu} C++ +runtime code expects to see. + +@smallexample + __CTOR_LIST__ = .; + LONG((__CTOR_END__ - __CTOR_LIST__) / 4 - 2) + *(.ctors) + LONG(0) + __CTOR_END__ = .; + __DTOR_LIST__ = .; + LONG((__DTOR_END__ - __DTOR_LIST__) / 4 - 2) + *(.dtors) + LONG(0) + __DTOR_END__ = .; +@end smallexample + +If you are using the @sc{gnu} C++ support for initialization priority, +which provides some control over the order in which global constructors +are run, you must sort the constructors at link time to ensure that they +are executed in the correct order. When using the @code{CONSTRUCTORS} +command, use @samp{SORT(CONSTRUCTORS)} instead. When using the +@code{.ctors} and @code{.dtors} sections, use @samp{*(SORT(.ctors))} and +@samp{*(SORT(.dtors))} instead of just @samp{*(.ctors)} and +@samp{*(.dtors)}. + +Normally the compiler and linker will handle these issues automatically, +and you will not need to concern yourself with them.

Symbol versions are +only useful when using shared libraries. The dynamic linker can use +symbol versions to select a specific version of a function when it runs +a program that may have been linked against an earlier version of the +shared library. + +You can include a version script directly in the main linker script, or +you can supply the version script as an implicit linker script. You can +also use the @samp{--version-script} linker option. + +The syntax of the @code{VERSION} command is simply +@smallexample +VERSION @{ version-script-commands @} +@end smallexample + +The format of the version script commands is identical to that used by +Sun's linker in Solaris 2.5. The version script defines a tree of +version nodes. You specify the node names and interdependencies in the +version script. You can specify which symbols are bound to which +version nodes, and you can reduce a specified set of symbols to local +scope so that they are not globally visible outside of the shared +library. + +The easiest way to demonstrate the version script language is with a few +examples. + +@smallexample +VERS_1.1 @{ + global: + foo1; + local: + old*; + original*; + new*; +@}; + +VERS_1.2 @{ + foo2; +@} VERS_1.1; + +VERS_2.0 @{ + bar1; bar2; +@} VERS_1.2; +@end smallexample + +This example version script defines three version nodes. The first +version node defined is @samp{VERS_1.1}; it has no other dependencies. +The script binds the symbol @samp{foo1} to @samp{VERS_1.1}. It reduces +a number of symbols to local scope so that they are not visible outside +of the shared library. + +Next, the version script defines node @samp{VERS_1.2}. This node +depends upon @samp{VERS_1.1}. The script binds the symbol @samp{foo2} +to the version node @samp{VERS_1.2}. + +Finally, the version script defines node @samp{VERS_2.0}. This node +depends upon @samp{VERS_1.2}. The scripts binds the symbols @samp{bar1} +and @samp{bar2} are bound to the version node @samp{VERS_2.0}. + +When the linker finds a symbol defined in a library which is not +specifically bound to a version node, it will effectively bind it to an +unspecified base version of the library. You can bind all otherwise +unspecified symbols to a given version node by using @samp{global: *} +somewhere in the version script. + +The names of the version nodes have no specific meaning other than what +they might suggest to the person reading them. The @samp{2.0} version +could just as well have appeared in between @samp{1.1} and @samp{1.2}. +However, this would be a confusing way to write a version script. + +When you link an application against a shared library that has versioned +symbols, the application itself knows which version of each symbol it +requires, and it also knows which version nodes it needs from each +shared library it is linked against. 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. + +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. + +@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.

If you obtained @code{ld} from a support organization, we +recommend you contact that organization first. + +You can find contact information for many support companies and +individuals in the file @file{etc/SERVICE} in the @sc{gnu} Emacs +distribution. + +Otherwise, send bug reports for @code{ld} to +@samp{bug-gnu-utils@@gnu.org}. + +The fundamental principle of reporting bugs usefully is this: +@strong{report all the facts}. If you are not sure whether to state a +fact or leave it out, state it! + +Often people omit facts because they think they know what causes the +problem and assume that some details do not matter. Thus, you might +assume that the name of 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. Therefore, always write your bug reports on the assumption +that the bug has not been reported previously. + +Sometimes people give a few sketchy facts and ask, ``Does this ring a +bell?'' Those bug reports are useless, and we urge everyone to +@emph{refuse to respond to them} except to chide the sender to report +bugs properly. + +To enable us to fix the bug, you should include all these things: + +@itemize @bullet +@item +The version of @code{ld}. @code{ld} announces it if you start it with +the @samp{--version} argument. + +Without this, we will not know whether there is any point in looking for +the bug in the current version of @code{ld}. + +@item +Any patches you may have applied to the @code{ld} source, including any +patches made to the @code{BFD} library. + +@item +The type of machine you are using, and the operating system name and +version number. + +@item +What compiler (and its version) was used to compile @code{ld}---e.g. +``@code{gcc-2.7}''. + +@item +The command arguments you gave the linker to link your example and +observe the bug. To guarantee you will not omit something important, +list them all. A copy of the Makefile (or the output from make) is +sufficient. + +If we were to try to guess the arguments, we would probably guess wrong +and then we might not encounter the bug. + +@item +A complete input file, or set of input files, that will reproduce the +bug. It is generally most helpful to send the actual object files, +uuencoded if necessary to get them through the mail system. Making them +available for anonymous FTP is not as good, but may be the only +reasonable choice for large object files. + +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 @code{ld} gets a fatal signal, then we +will certainly notice it. But if the bug is incorrect output, we might +not notice unless it is glaringly wrong. You might as well not give us +a chance to make a mistake. + +Even if the problem you experience is a fatal signal, you should still +say so explicitly. Suppose something strange is going on, such as, your +copy of @code{ld} is out of synch, or you have encountered a bug in the +C library on your system. (This has happened!) Your copy might crash +and ours would not. If you told us to expect a crash, then when ours +fails to crash, we would know that the bug was not happening for us. If +you had not told us to expect a crash, then we would not be able to draw +any conclusion from our observations. + +@item +If you wish to suggest changes to the @code{ld} source, send us context +diffs, as generated by @code{diff} with the @samp{-u}, @samp{-c}, or +@samp{-p} option. Always send diffs from the old file to the new file. +If you even discuss something in the @code{ld} source, refer to it by +context, not by line number. + +The line numbers in our development sources will not match those in your +sources. Your line numbers would convey no useful information to us. +@end itemize + +Here are some things that are not necessary: + +@itemize @bullet +@item +A description of the envelope of the bug. + +Often people who encounter a bug spend a lot of time investigating +which changes to the input file will make the bug go away and which +changes will not affect it. + +This is often time consuming and not very useful, because the way we +will find the bug is by running a single example under the debugger +with breakpoints, not by pure deduction from a series of examples. +We recommend that you save your time for something else. + +Of course, if you can find a simpler example to report @emph{instead} +of the original one, that is a convenience for us. Errors in the +output will be easier to spot, running under the debugger will take +less time, and so on. + +However, simplification is not vital; if you do not want to do this, +report the bug anyway and send us the entire test case you used. + +@item +A patch for the bug. + +A patch for the bug does help us if it is a good one. But do not omit +the necessary information, such as the test case, on the assumption that +a patch is all we need. We might see problems with your patch and decide +to fix the problem another way, or we might not understand it at all. + +Sometimes with a program as complicated as @code{ld} it is very hard to +construct an example that will make the program follow a certain path +through the code. If you do not send us the example, we will not be +able to construct one, so we will not be able to verify that the bug is +fixed. + +And if we cannot understand what bug you are trying to fix, or why your +patch should be an improvement, we will not install it. A test case will +help us to understand. + +@item +A guess about what the bug is or what it depends on. + +Such guesses are usually wrong. Even we cannot guess right about such +things without first using the debugger to find the facts. +@end itemize + +@node MRI +@appendix MRI Compatible Script Files +@cindex MRI compatibility +To aid users making the transition to @sc{gnu} @code{ld} from the MRI +linker, @code{ld} can use MRI compatible linker scripts as an +alternative to the more general-purpose linker scripting language +described in @ref{Scripts}. MRI compatible linker scripts have a much +simpler command set than the scripting language otherwise used with +@code{ld}. @sc{gnu} @code{ld} supports the most commonly used MRI +linker commands; these commands are described here. + +In general, MRI scripts aren't of much use with the @code{a.out} object +file format, since it only has three sections and MRI scripts lack some +features to make use of them. + +You can specify a file containing an MRI-compatible script using the +@samp{-c} command-line option. + +Each command in an MRI-compatible script occupies its own line; each +command line starts with the keyword that identifies the command (though +blank lines are also allowed for punctuation). If a line of an +MRI-compatible script begins with an unrecognized keyword, @code{ld} +issues a warning message, but continues processing the script. + +Lines beginning with @samp{*} are comments. + +You can write these commands using all upper-case letters, or all +lower case; for example, @samp{chip} is the same as @samp{CHIP}. +The following list shows only the upper-case form of each command. + +@table @code +@cindex @code{ABSOLUTE} (MRI) +@item ABSOLUTE @var{secname} +@itemx ABSOLUTE @var{secname}, @var{secname}, @dots{} @var{secname} +Normally, @code{ld} includes in the output file all sections from all +the input files.

If the @code{ABSOLUTE} command is used at all in a +script, then only the sections named explicitly in @code{ABSOLUTE} +commands will appear in the linker output. You can still use other +input sections (whatever you select on the command line, or using +@code{LOAD}) to resolve addresses in the output file. + +@cindex @code{ALIAS} (MRI) +@item ALIAS @var{out-secname}, @var{in-secname} +Use this command to place the data from input section @var{in-secname} +in a section called @var{out-secname} in the linker output file. + +@var{in-secname} may be an integer. + +@cindex @code{ALIGN} (MRI) +@item ALIGN @var{secname} = @var{expression} +Align the section called @var{secname} to @var{expression}.

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{SCRIPT_NAME} is set to @var{script}, @file{genscripts.sh} will use +the script @file{scriptteml/@var{script}.sc}. + +@item TEMPLATE_NAME +This is the name of the @file{emultemlp} 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 @file{scripttempl} script will normally +use it in an @code{OUTPUT_FORMAT} expression in the linker script. + +@item ARCH +This is normally set to indicate the architecture to use (e.g., +@samp{sparc}). The @file{scripttempl} script will normally use it in an +@code{OUTPUT_ARCH} expression in the linker script. + +@item ENTRY +Some @file{scripttempl} scripts use this to set the entry address, in an +@code{ENTRY} expression in the linker script. + +@item TEXT_START_ADDR +Some @file{scripttempl} scripts use this to set the start address of the +@samp{.text} section. + +@item NONPAGED_TEXT_START_ADDR +If this is defined, the @file{genscripts.sh} script sets +@code{TEXT_START_ADDR} to its value before running the +@file{scripttempl} script for the @code{-n} and @code{-N} options +(@pxref{linker scripts}). + +@item SEGMENT_SIZE +The @file{genscripts.sh} script uses this to set the default value of +@code{DATA_ALIGNMENT} when running the @file{scripttempl} script. + +@item TARGET_PAGE_SIZE +If @code{SEGMENT_SIZE} is not defined, the @file{genscripts.sh} script +uses this to define it. + +@item ALIGNMENT +Some @file{scripttempl} scripts set this to a number to pass to +@code{ALIGN} to set the required alignment for the @code{end} symbol. +@end table + +@node linker scripts +@section @file{scripttempl} scripts + +Each linker target uses a @file{scripttempl} script to generate the +default linker scripts. The name of the @file{scripttempl} script is +set by the @code{SCRIPT_NAME} variable in the @file{emulparams} script. +If @code{SCRIPT_NAME} is set to @var{script}, @code{genscripts.sh} will +invoke @file{scripttempl/@var{script}.sc}. + +The @file{genscripts.sh} script will invoke the @file{scripttempl} +script 5 or 6 times. Each time it will set the shell variable +@code{LD_FLAG} to a different value. When the linker is run, the +options used will direct it to select a particular script. (Script +selection is controlled by the @code{get_script} emulation entry point; +this describes the conventional behaviour). + +The @file{scripttempl} script should just write a linker script, written +in the linker command language, to standard output. If the emulation +name--the name of the @file{emulparams} file without the @file{.sc} +extension--is @var{emul}, then the output will be directed to +@file{ldscripts/@var{emul}.@var{extension}} in the build directory, +where @var{extension} changes each time the @file{scripttempl} script is +invoked. + +Here is the list of values assigned to @code{LD_FLAG}. + +@table @code +@item (empty) +The script generated is used by default (when none of the following +cases apply). The output has an extension of @file{.x}. +@item n +The script generated is used when the linker is invoked with the +@code{-n} option. The output has an extension of @file{.xn}. +@item N +The script generated is used when the linker is invoked with the +@code{-N} option. The output has an extension of @file{.xbn}. +@item r +The script generated is used when the linker is invoked with the +@code{-r} option. The output has an extension of @file{.xr}. +@item u +The script generated is used when the linker is invoked with the +@code{-Ur} option. The output has an extension of @file{.xu}. +@item shared +The @file{scripttempl} script is only invoked with @code{LD_FLAG} set to +this value if @code{GENERATE_SHLIB_SCRIPT} is defined in the +@file{emulparams} file. The @file{emultempl} script must arrange to use +this script at the appropriate time, normally when the linker is invoked +with the @code{-shared} option. 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 new file mode 100644 index 0000000..aa5c681 --- /dev/null +++ b/ld/ldlang.c @@ -0,0 +1,4703 @@ +/* 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.
