2014-08-22Delete redundant struct cie fieldAlan Modra2-5/+8
cie->output_sec is used to when merging CIEs to ensure that only CIEs from the same output section are merged. I noticed an assignment to this field in _bfd_elf_parse_eh_frame, and thought "That's wrong, output_section isn't set properly when _bfd_elf_parse_eh_frame is called from gc-sections code". It turns out that this assignment is premature, and in fact a dead store. find_merged_cie overwrites with the correct value before the field is ever used. On looking a little more it becomes apparent that cie->cie_inf.u.cie.u.sec->output_section holds the same value, so cie->output_sec is redundant. * elf-eh-frame.c (struct cie): Delete "output_sec" field. (cie_eq, cie_compute_hash): Use output_section from cie_inf instead.
2014-08-22Index PowerPC64 linker generated .eh_frame in .eh_frame_hdrAlan Modra5-169/+190
I noticed recently that .eh_frame FDEs generated by the linker for call stubs and .glink weren't being indexed in .eh_frame_hdr, due to bfd_elf_discard_info being run before the linker generated .eh_frame sections were available for parsing. This patch moves code around in elf64-ppc.c and ppc64elf.em to avoid that problem. Another problem fixed here is that --gc-sections parses .eh_frame early, and the existing machinery allows only one go at parsing the .eh_frame sections. That resulted in the linker generated .eh_frame CIEs not being merged and no .eh_frame_hdr index entries for those FDEs. It turns out that all the info from parsing .eh_frame is attached to the section, so order of parsing isn't important, and after parsing sec_info_type being set will prevent a section being parsed again. At least, when parsing doesn't hit an error. So there isn't really any need for "parsed_eh_frame". "merge_cies" is also redundant, which means _bfd_elf_{begin,end}_eh_frame_parsing can also disappear. bfd/ * elf-bfd.h (struct eh_frame_hdr_info): Delete merge_cies and parsed_eh_frames.

This also makes --enable-plugins default to on for hosts that can support plugins, so we have consistent lto toolchain support.

The main aim of this change was to have non_ir_ref set correctly on new indirect symbols.

2014-08-05Fix LTO vs. COFF archivesAlan Modra10-560/+187
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.
