Check ELF relocs after opening all input files
Delaying checking ELF relocations until opening all input files so
that symbol information is final when relocations are checked. This
is only enabled for x86 targets.
bfd/
* elf-bfd.h (_bfd_elf_link_check_relocs): New.
* elflink.c (_bfd_elf_link_check_relocs): New function.
(elf_link_add_object_symbols): Call _bfd_elf_link_check_relocs
if check_relocs_after_open_input is FALSE.
include/
* bfdlink.h (bfd_link_info): Add check_relocs_after_open_input.
ld/
* emulparams/elf32_x86_64.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
New.
* emulparams/elf_i386.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/elf_i386_be.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/elf_i386_chaos.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/elf_i386_ldso.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/elf_i386_vxworks.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/elf_x86_64.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emulparams/i386nto.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):
Likewise.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_parse):
Set check_relocs_after_open_input to TRUE if
CHECK_RELOCS_AFTER_OPEN_INPUT is yes.
(gld${EMULATION_NAME}_after_open): Call
_bfd_elf_link_check_relocs on all inputs if
check_relocs_after_open_input is TRUE.
