Others will ignore the option. - -* Added SORT to the linker script language to permit sorting sections by file - name or section name. - -* Added EXTERN to the linker script language as an equivalent to the -u - command-line option. - -* Added ASSERT to the linker script language. - -* Added EXCLUDE_FILE to the linker script language for further control over - wildcard file names. - -* Added -O option to optimize linker output (as of this writing, this only -affects ELF shared library generation). - -* The -e option now accepts a number as well as a symbol name. - -* Added --no-undefined option to disallow undefined symbols when creating a - shared library. - -* Added --demangle and --no-demangle options. - -Changes in version 2.9: - -* Added SQUAD to the linker script language. - -* New option --no-warn-mismatch. - -* The MEMORY command now parses the attributes to determine where sections that - are not placed in a specific memory region are placed. - -Changes in version 2.8: - -* Linker scripts may now contain shell wildcard characters for file and section - names. - -* The linker now supports symbol versions in ELF. - -* The NOCROSSREFS command was added to the linker script language. - -* The LOADADDR expression was added to the linker script language. - -* MAX and MIN functions were added to the linker script language. - -* The OVERLAY construct was added to the linker script language. - -* New option --warn-section-align to warn when the address of an output section - changes due to alignment of an input section. - -* New options --filter/-F and --auxiliary/-f. - -Changes in version 2.7: - -* New option --cref to print out a cross reference table. - -* New option --wrap SYMBOL. - -* New option --no-whole-archive, to turn off the effect of --whole-archive. - -* Input sections assigned to the output section /DISCARD/ in the linker script - are not included in the output file. - -* The SunOS and ELF linkers now merge stabs debugging information which uses - the N_BINCL and N_EINCL stab types. This reduces the amount of debugging - information generated. - -Changes in version 2.6: - -* When an ELF section name is representable as a C identifier (this is not true -of most ELF section names), the linker will automatically define symbols -__start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the -beginning and the end of the section. This is used by glibc. - -* When an ELF section named .gnu.warning is encountered in an input file, the -contents of the section are displayed as an error message, and the section is -not copied into the output file. This is used by glibc. - -* When an ELF section named .gnu.warning.SYMBOL is encountered in an input -file, and the symbol SYMBOL is referenced by some object file, the contents of -the section are displayed as an error message. The section is not copied into -the output file, unless doing a 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: |
