2014-08-05Fix LTO vs. COFF archivesAlan Modra1-1/+3
Avoid scan of symbols on objects in coff archives since we don't need to do anything special with common symbols. The scan is quite useless, and breaks LTO due to slim LTO objects not having symbols available until after the plugin has claimed them. Instead we can add objects based on their archive symbol map. Also, rip out the archive symbol hash table used by the generic linker. Using a hash breaks one feature of unix archive linking; The first object file in an archive defining any given symbol should be the object extracted to satisfy that symbol. What's more a hash isn't much faster except in pathological cases where object file ordering causes many scans of the archive. See the comment which I'm removing from elf_link_add_archive_symbols. Finally, tidy elflink.c archive handling a little. PR 13557 * linker.c (struct archive_list, struct archive_hash_entry, struct archive_hash_table, archive_hash_newfunc, archive_hash_table_init, archive_hash_lookup, archive_hash_allocate, archive_hash_table_free): Delete.
