* 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.
