--- Comment #3 from Sourceware Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=a6f8fe0a9e9cbe871652e46ba7c22d5e9fb86208 commit a6f8fe0a9e9cbe871652e46ba7c22d5e9fb86208 Author: H.J. Lu <hjl.to...@gmail.com> Date: Wed Aug 14 20:50:02 2024 -0700 lto: Don't include unused LTO archive members in output When plugin_object_p is called by elf_link_is_defined_archive_symbol to check if a symbol in archive is a real definition, set archive member plugin_format to bfd_plugin_yes_unused to avoid including the unused LTO archive members in linker output. When plugin_object_p is called as known used, call plugin claim_file if plugin_format is bfd_plugin_unknown or bfd_plugin_yes_unused. To get the proper support for archives with LTO common symbols with GCC, the GCC fix for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116361 is needed. bfd/ PR ld/32083 * archures.c (bfd_arch_get_compatible): Treat bfd_plugin_yes_unused the same as bfd_plugin_yes. * elflink.c (elf_link_is_defined_archive_symbol): Likewise. * bfd.c (bfd_plugin_format): Add bfd_plugin_yes_unused. * plugin.c (try_claim): Try claim_file_v2 first. * bfd-in2.h: Regenerated. ld/ PR ld/32083 * plugin.c (plugin_call_claim_file): Add an argument to return if LDPT_REGISTER_CLAIM_FILE_HOOK_V2 is used. (plugin_object_p): When KNOWN_USED is false, we call plugin claim_file if plugin_format is bfd_plugin_unknown and set plugin_format to bfd_plugin_yes_unused on LTO object. When KNOWN_USED is true, we call plugin claim_file if plugin_format is bfd_plugin_unknown or bfd_plugin_yes_unused. Signed-off-by: H.J.
