2002-01-24 Alexandre Oliva <aoliva@redhat.com> * emulparams/shelf32.sh (STACK_ADDR): Define as formerly defined in OTHER_RELOCATABLE_SECTIONS. 2002-01-18 Alexandre Oliva <aoliva@redhat.com> * emulparams/shelf32.sh (STACK_ADDR): Define. (OTHER_RELOCATABLE_SECTIONS): Renamed to... (OTHER_SECTIONS): this. Removed stack settings. * emulparams/shelf64.sh (OTHER_RELOCATABLE_SECTIONS): Do not set. (OTHER_SECTIONS): Reset after sourcing shelf32.sh. 2001-03-12 DJ Delorie <dj@redhat.com> * emultempl/sh64elf.em (sh64_elf_$_before_allocation): Disable relaxing if any shmedia or mixed sections are found. 2001-03-07 DJ Delorie <dj@redhat.com> * emultempl/sh64elf.em (sh64_elf_before_allocation): Pass f to einfo. Gracefully decline to output to non-elf formats. 2001-03-06 Hans-Peter Nilsson <hpn@redhat.com> * emulparams/shelf64.sh (OTHER_RELOCATING_SECTIONS) <.stack>: Default to _end aligned to next multiple of 0x40000, plus 0x40000. * emulparams/shelf32.sh: Ditto. 2001-01-14 Hans-Peter Nilsson <hpn@cygnus.com> * emulparams/shelf32.sh (OTHER_RELOCATING_SECTIONS): Tweak comment. 2001-01-10 Ben Elliston <bje@redhat.com> * emulparams/shelf32.sh (OTHER_RELOCATING_SECTIONS): Avoid non-portable shell constructs. From Hans-Peter Nilsson. 2001-01-09 Hans-Peter Nilsson <hpn@cygnus.com> * emulparams/shelf64.sh (EXTRA_EM_FILE): Define empty. * Makefile.am (eshelf64.c, eshlelf64.c, eshlelf32.c): Adjust dependencies to the shell script include chain. * Makefile.in: Regenerate. 2001-01-06 Hans-Peter Nilsson <hpn@cygnus.com> * emultempl/sh64elf.em: Update and tweak comments. (sh64_elf_${EMULATION_NAME}_after_allocation): Always allocate and make a .cranges section SEC_IN_MEMORY. 2000-12-30 Hans-Peter Nilsson <hpn@cygnus.com> * emultempl/sh64elf.em (sh64_elf_${EMULATION_NAME}_before_allocation): Don't stop when .cranges section found to be necessary; continue and set stored section contents flags for sections with non-mixed contents. Use a struct sh64_section_data container and sh64_elf_section_data to store contents-type flags. Remove unused update of "isec". (sh64_elf_${EMULATION_NAME}_after_allocation): Only process sections marked SHF_SH5_ISA32_MIXED. Use sh64_elf_section_data to access contents-type flags. Assert that the associated container is initialized. Use that container, not elf_gp_size, to hold size of linker-generated cranges contents. 2000-12-18 Hans-Peter Nilsson <hpn@cygnus.com> * emultempl/sh64elf.em (sh64_elf_${EMULATION_NAME}_before_allocation): Exit early if there's already a .cranges section. When section flag difference is found, don't NULL-check cranges a second time. Tweak comments. (sh64_elf_${EMULATION_NAME}_after_allocation): Use size after merging, not max size, as size of ld-generated .cranges contents. Don't set ELF section flags in output section. When checking for needed .cranges descriptors, don't use a variable; compare incoming ELF section flags directly to SHF_SH5_ISA32_MIXED. Tweak comments. 2000-12-18 Hans-Peter Nilsson <hpn@cygnus.com> * emultempl/sh64elf.em: New file. * Makefile.am (eshelf32.c, eshlelf32.c): Adjust dependencies. * Makefile.in: Regenerate. * emulparams/shelf32.sh (OUTPUT_FORMAT): Only set if not set. (OTHER_RELOCATING_SECTIONS): Ditto. (EXTRA_EM_FILE): New, set to sh64elf if not set. * emulparams/shlelf32.sh: Stub out all settings except OUTPUT_FORMAT. Source shelf32.sh. * emulparams/shelf64.sh: Similar, but also keep ELF_SIZE and OTHER_RELOCATING_SECTIONS. (OTHER_RELOCATING_SECTIONS): Remove .cranges. * emulparams/shlelf64.sh: Stub out all settings except OUTPUT_FORMAT. Source shelf64.sh. 2000-12-15 Hans-Peter Nilsson <hpn@cygnus.com> * emulparams/shelf64.sh (OTHER_RELOCATING_SECTIONS): Include .cranges section. (DATA_START_SYMBOLS): Define, provide ___data. (OTHER_READONLY_SYMBOLS): Define, provide ___rodata and align to 8 for consecutive .data section. (OTHER_GOT_SECTIONS): Define, align to 8 for consecutive .bss section after .data section. * emulparams/shlelf64.sh: Ditto. * emulparams/shelf32.sh: Ditto. (ALIGNMENT): Define to 8. * emulparams/shelf32.sh: Ditto. 2000-12-12 Hans-Peter Nilsson <hpn@cygnus.com> * configure.tgt (sh64-*-elf*): Assign targ_extra_libpath to get built-in linker scripts. 2000-11-30 Hans-Peter Nilsson <hpn@cygnus.com> * emulparams/shlelf64.sh: New. * emulparams/shelf64.sh: New. * configure.tgt (sh64-*-elf*): Add shelf64 and shlelf64 to targ_extra_emuls. * Makefile.am: Add support for shlelf64 and shelf64. * Makefile.in: Regenerate. 2000-11-29 Hans-Peter Nilsson <hpn@cygnus.com> * configure.tgt (sh64-*-elf*): Add shelf as default. Add shlelf to targ_extra_emuls. 2000-11-24 Hans-Peter Nilsson <hpn@cygnus.com> * emulparams/shelf32.sh: New file. * emulparams/shlelf32.sh: New file. * Makefile.am: Add support for shlelf32 and shelf32. * configure.tgt: Map sh64-*-elf* to shlelf32 and shelf32. * Makefile.in: Regenerate. |

README for LD This is the GNU linker. It is distributed with other "binary utilities" which should be in ../binutils. See ../binutils/README for more general notes, including where to send bug reports. There are many features of the linker: * The linker uses a Binary File Descriptor library (../bfd) that it uses to read and write object files. This helps insulate the linker itself from the format of object files. * The linker supports a number of different object file formats. It can even handle multiple formats at once: Read two input formats and write a third. * The linker can be configured for cross-linking. * The linker supports a control language. * There is a user manual (ld.texinfo), as well as the beginnings of an internals manual (ldint.texinfo). Installation ============ See ../binutils/README. If you want to make a cross-linker, you may want to specify a different search path of -lfoo libraries than the default. You can do this by setting the LIB_PATH variable in ./Makefile. To build just the linker, make the target all-ld from the top level directory (one directory above this one). Porting to a new target ======================= See the ldint.texinfo manual. Reporting bugs etc =========================== See ../binutils/README. Known problems ============== The Solaris linker normally exports all dynamic symbols from an executable. 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}..." (no parens) and make sure the emulparams script used exports any shell variables it sets.
