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.
