   4         * elflink.c (bfd_elf_record_link_assignment): Revert last
   5         change and don't ever clear `forced_local'.  Set `mark'
   6         unconditionally.
   7         (elf_gc_sweep_symbol_info, elf_gc_sweep_symbol): Reorder within
   8         file.
   9         (elf_gc_sweep): Move the call to `elf_gc_sweep_symbol'...

  11         * elf32-ppc.c (ppc_elf_tls_setup): Don't clear `forced_local'
  12         and set `mark' instead in `__tls_get_addr_opt' processing.

  17         * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Merge two cases
  18         where dynamic relocs are preferable.  Allow ifunc too.
  19         (ensure_undefweak_dynamic): New function.
  20         (allocate_dynrelocs): Use it here.  Move plt handling last and
  21         don't make symbols dynamic, simplifying loop.  Only make undef
  22         weak symbols with GOT entries dynamic.  Correct condition
  23         for GOT relocs.  Handle dynamic relocs on ifuncs.  Correct
  24         comments.  Remove goto.
  25         (ppc_elf_relocate_section): Correct test for using dynamic
  26         symbol on GOT relocs.  Rearrange test for emitting GOT relocs
  27         to suit.  Set up explicit tls_index entries and implicit GOT
  28         tls_index entries resolvable at link time for
  29         __tls_get_addr_opt.  Simplify test to clear mem for prelink.
  30         * elf64-ppc.c (allocate_got): Correct condition for GOT relocs.
  31         (ensure_undefweak_dynamic): New function.
  32         (allocate_dynrelocs): Use it here.  Only make undef weak symbols
  33         with GOT entries dynamic.  Remove unnecessary test of
  34         WILL_CALL_FINISH_DYNAMIC_SYMBOL in PLT handling.
  35         (ppc64_elf_relocate_section): Correct test for using dynamic
  36         symbol on GOT relocs.  Rearrange test for emitting GOT relocs
  37         to suit.  Set up explicit tls_index entries and implicit GOT
  38         tls_index entries resolvable at link time for __tls_get_addr_opt.
  39         Simplify expression to clear mem for prelink.
