2014-10-13Run eh_frame optimisation for relocatable linkAlan Modra1-7/+7

2014-09-11Move ELF section headers to end of object fileAlan Modra1-5/+3
Currently, section ordering differs a little for non-loaded reloc sections output by ld -emit-relocs or ld -r and that after passing such objects through objcopy. Not that it really matters, but it would be better for a simple objcopy to produce an unchanged output object file. Also, section headers are put somewhere in the middle of the non-loaded sections, again slightly differently for ld and objcopy. This patch fixes these discrepancies and puts section headers last, which is where gold puts them, and is where bfd_from_remote_memory wrongly assumed they will be found. bfd/ * elf.c (assign_file_positions_except_relocs): Move section header placement to..

2014-08-22Index PowerPC64 linker generated .eh_frame in .eh_frame_hdrAlan Modra1-14/+6
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.

2014-08-12Change ld "notice" interface for better handling of indirect symbolsAlan Modra1-1/+1
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 Modra1-43/+10
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.

2014-07-08Copy st_other for linker script symbol assignmentsAlan Modra1-6/+13
This fixes a problem seen on powerpc64le ELFv2 when creating a function symbol alias with ld --defsym. st_other needs to be copied from the source symbol to the alias in order to set up the local entry offset for the alias. I decided to make this change in the generic ELF code rather than in elf64-ppc.c since it looks like other targets that use st_other bits might benefit too. bfd/ * elflink.c (_bfd_elf_copy_link_hash_symbol_type): Copy st_other bits from source to dest. * linker.c (_bfd_generic_copy_link_hash_symbol_type): Update comment. * targets.c (struct bfd_target <_bfd_copy_link_hash_symbol_type>): Likewise. * bfd-in2.h: Regenerate. ld/testsuite/ * ld-powerpc/defsym.s, * ld-powerpc/defsym.d: New test. * ld-powerpc/powerpc.exp: Run it.
