PR ld/12942
bfd/ * elflink.c (elf_link_add_object_symbols): Use elf_discarded_section rather than kept_section to determine whether a symbol is from a discarded section. * cofflink.c (coff_link_add_symbols): Make symbols from discarded sections appear undefined. * elf-bfd.h (_bfd_elf_section_already_linked): Replace "asection *" with "struct already_linked *". * libbfd-in.h (_bfd_nolink_section_already_linked): Likewise. (_bfd_generic_section_already_linked): Likewise. (bfd_section_already_linked_table_insert): Likewise. (struct already_linked): New. (struct bfd_section_already_linked): Use it. * elflink.c (_bfd_elf_section_already_linked): Replace. "asection *" with "struct already_linked *". Replace the plugin dummy with the LTO output. * linker.c (_bfd_generic_section_already_linked): Likewise. * targets.c (struct already_linked): Add forward declaration. (bfd_target): Replace "struct bfd_section *" with "struct already_linked *" in _section_already_linked. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. include/ * bfdlink.h (bfd_link_info): Add loading_lto_outputs. ld/ * ldlang.c (section_already_linked): Pass "struct already_linked *" to bfd_section_already_linked. (lang_process): Set link_info.loading_lto_outputs before loading LTO outputs. * plugin.c: Include "libbfd.h". (add_symbols): Call bfd_section_already_linked with comdat_key.
