bfd/ * config.bfd: Use bfd_elf32_i386_vxworks_vec for i?86-*-vxworks. * configure.in: Add bfd_elf32_i386_vxworks_vec. i386 targets need elf-vxworks.lo. * configure: Regenerate. * Makefile.am (BFD32_BACKENDS): Add elf-vxworks.lo. (BFD32_BACKENDS_CFILES): Add elf-vxworks.c. (elf32-i386.lo): Depend on elf-vxworks.h. (elf-vxworks.lo): New rule. * Makefile.in: Regenerate. * elf-bfd.h (elf_backend_data): Update type of elf_backend_emit_relocs. (_bfd_elf_link_output_relocs): Update prototype. * elflink.c (_bfd_elf_link_output_relocs): Always use bed->elf_backend_emit_relocs when outputting relocations. * elfxx-target.h (elf_backend_emit_relocs): Default to _bfd_elf_link_output_relocs. * targets.c (bfd_elf32_i386_vxworks_vec): Declare. (_bfd_target_vector): Add bfd_elf32_i386_vxworks_vec. * elf32-i386.c: Add elf32-i386-vxworks target BFD. (elf_i386_plt0_entry): Remove padding. (elf_i386_pic_plt0_entry): Ditto. (PLTRESOLVE_RELOCS_SHLIB, PLTRESOLVE_RELOCS): Define. (PLT_NON_JUMP_SLOT_RELOCS): Define. (elf_i386_link_hash_table): Add srelplt2, hgot, hplt, is_vxworks and plt0_pad_byte fields. (elf_i386_link_hash_table_create): Zero them. (elf_i386_create_dynamic_sections): Create static relocation section. (allocate_dynrelocs): Allocate space for static PLT relocations. (elf_i386_size_dynamic_sections): Save shortcuts to PLT and GOT symbols. Give PLT symbols function type. Don't strip PLT sections if we have exported symbols from them. (elf_i386_finish_dynamic_symbol): Fill in VxWorks PLT static relocation section. Don't mark _GLOBAL_OFFSET_TABLE_ as absolute on VxWorks. (elf_i386_finish_dynamic_sections): Allow different pad bytes. Add relocation for GOT location. Fill in PLT static relocations. (elf_i386_vxworks_link_hash_table_create): New function. (elf_i386_vxworks_link_output_symbol_hook): New function. * elf-vxworks.h: New file. gas/ * config/tc-i386.h (ELF_TARGET_FORMAT): Define for TE_VXWORKS. gas/testsuite/ * gas/i386/i386.exp: Don't run divide test on vxworks. ld/ * Makefile.am: Add eelf_i386_vxworks. * Makefile.in: Regenerate. * configure.tgt: Make i?86-*-vxworks use targ_emul=elf_i386_vxworks. * emulparams/elf_i386_vxworks.sh: New file. * emulparams/vxworks.sh: New file. * scripttempl/elf.sc: Add DATA_END_SYMBOLS and ETEXT_NAME.
