-Subject: ELF/BFD: Limit `_bfd_elf_link_renumber_dynsyms' call in section GC
-
-Consistently call `_bfd_elf_link_renumber_dynsyms' only if linking a
-dynamic binary, complementing code in `bfd_elf_size_dynsym_hash_dynstr'
-and commit ccabcbe51e85 ("New attempt at fixing MIPS --gc-sections et
-al."), <https://sourceware.org/ml/binutils/2005-08/msg00258.html>.
-
- bfd/
- * elflink.c (elf_gc_sweep): Only call
- `_bfd_elf_link_renumber_dynsyms' if dynamic sections have been
- created.
-

-Subject: PR ld/21334: Always call `_bfd_elf_link_renumber_dynsyms' if required
-
-Complement commit e17b0c351f0b ("MIPS/BFD: Respect the ELF gABI dynamic
-symbol table sort requirement") and correct an inconsistency in dynamic
-symbol accounting data causing an assertion failure in the MIPS backend:
-
-ld: BFD (GNU Binutils) 2.28.51.20170330 assertion fail
-../../binutils-gdb/bfd/elfxx-mips.c:3860
-
-in the course of making a GOT entry in a static binary to satisfy a GOT
-relocation present in input, due to the local dynamic symbol count not
-having been established.
-
-To do so let backends request `_bfd_elf_link_renumber_dynsyms' to be
-always called, rather than where a dynamic binary is linked only, and
-then make this request in the MIPS backend.
-
- bfd/
- PR ld/21334
- * elf-bfd.h (elf_backend_data): Add `always_renumber_dynsyms'
- member.
- * elfxx-target.h [!elf_backend_always_renumber_dynsyms]
- (elf_backend_always_renumber_dynsyms): Define.
- (elfNN_bed): Initialize `always_renumber_dynsyms' member.
- * elfxx-mips.h (elf_backend_always_renumber_dynsyms): Define.
- * elflink.c (bfd_elf_size_dynsym_hash_dynstr): Also call
- `_bfd_elf_link_renumber_dynsyms' if the backend has requested
- it.
- (elf_gc_sweep): Likewise.
