-Subject: [PATCH] PR 21412, get_reloc_section assumes .rel/.rela name for
- SHT_REL/RELA.
-
-This patch fixes an assumption made by code that runs for objcopy and
-strip, that SHT_REL/SHR_RELA sections are always named starting with a
-.rel/.rela prefix. I'm also modifying the interface for
-elf_backend_get_reloc_section, so any backend function just needs to
-handle name mapping.
-
- PR 21412
- * elf-bfd.h (struct elf_backend_data <get_reloc_section>): Change
- parameters and comment.
- (_bfd_elf_get_reloc_section): Delete.
- (_bfd_elf_plt_get_reloc_section): Declare.
- * elf.c (_bfd_elf_plt_get_reloc_section, elf_get_reloc_section):
- New functions. Don't blindly skip over assumed .rel/.rela prefix.
- Extracted from..
- (_bfd_elf_get_reloc_section): ..here. Delete.
- (assign_section_numbers): Call elf_get_reloc_section.
- * elf64-ppc.c (elf_backend_get_reloc_section): Define.
- * elfxx-target.h (elf_backend_get_reloc_section): Update.
