1377 * elf-bfd.h (struct elf_backend_data): Add gc_keep. Remove param
1379 (_bfd_elf_gc_keep): Declare.
1380 * elfxx-target.h (elf_backend_gc_keep): Define.
1381 (elfNN_bed): Init new field.
1382 * elflink.c (_bfd_elf_gc_keep): New function.
1383 (bfd_elf_gc_sections): Call gc_keep.
1384 * elf64-ppc.c (elf_backend_gc_keep): Define.
1385 (struct _ppc64_elf_section_data): Move .opd related fields to
1386 a struct so they don't occupy the same storage. Adjust accesses
1388 (ppc64_elf_gc_keep): New function, split out from..
1389 (ppc64_elf_gc_mark_hook): ..here. Don't call _bfd_elf_gc_mark
1390 to mark .opd section, just set gc_mark.
1391 (ppc64_elf_edit_opd): Remove no_opd_opt parm. Don't set opd->adjust
1392 unless we are changing .opd. Test non-NULL opd->adjust at all
1393 accesses throughout file.

1433 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
1434 fields. Rename u.cie.u.merged to u.cie.u.merged_with.
1435 (eh_frame_sec_info): Add a cies field.
1436 (eh_frame_hdr_info): Add a merge_cies field.
1437 * elf-eh-frame.c (cie): Add a reloc_index member to the personality

1444 CIE's eh_fde_cie at the associated element. Do not try to
1445 calculate the value of the personality routine here; record the
1446 offset of the relocation instead. Do not merge CIEs here.
