(_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. --- include/ChangeLog | 5 +++++ include/bfdlink.h | 3 +++ 2 files changed, 8 insertions(+) diff --git a/include/ChangeLog b/include/ChangeLog index c80aeb8a5..bf2c020fd 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,3 +1,8 @@ +2011-07-09 H.J.
