   4 Subject: ELF/BFD: Limit `_bfd_elf_link_renumber_dynsyms' call in section GC
   5
   6 Consistently call `_bfd_elf_link_renumber_dynsyms' only if linking a
   7 dynamic binary, complementing code in `bfd_elf_size_dynsym_hash_dynstr'
   8 and commit ccabcbe51e85 ("New attempt at fixing MIPS --gc-sections et
   9 al."), <https://sourceware.org/ml/binutils/2005-08/msg00258.html>.

  11         bfd/
  12         * elflink.c (elf_gc_sweep): Only call
  13         `_bfd_elf_link_renumber_dynsyms' if dynamic sections have been
  14         created.
