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.
