2624 * elfxx-mips.c (_bfd_mips_elf_gc_sweep_hook): Likewise.
2625 * elfxx-sparc.c (_bfd_sparc_elf_gc_sweep_hook): Likewise.
2626 * elflink.c (bfd_elf_gc_sections): Do not punt on relocatable output
2627 or executable output with relocations.
2629 2008-01-09 Nick Clifton <nickc@redhat.com>
2632 * elf32-fr30.c (fr30_elf_howto_table): Set partial_inplace field
2633 to FALSE for all relocs.
2635 2008-01-09 Richard Sandiford <rsandifo@nildram.co.uk>
2638 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
2639 fields. Rename u.cie.u.merged to u.cie.u.merged_with.
2640 (eh_frame_sec_info): Add a cies field.
2641 (eh_frame_hdr_info): Add a merge_cies field.
2642 * elf-eh-frame.c (cie): Add a reloc_index member to the personality
2644 (_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
2646 (_bfd_elf_parse_eh_frame): Remove tmp_cie. Ccreate an array of
2647 cie structures in all cases and use it instead of extended_cies.
2648 If merging, store the cie array in sec_info->cies and point each
2649 CIE's eh_fde_cie at the associated element. Do not try to
2650 calculate the value of the personality routine here; record the
2651 offset of the relocation instead. Do not merge CIEs here.
2652 (_bfd_elf_end_eh_frame_parsing): Do not free hdr_info->cies here...
2653 (_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
2654 (_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
2655 (find_merged_cie): New function.
2656 (_bfd_elf_gc_mark_fdes): Use it. Free sec_info->cies.

2661 * vms.c (vms_close_and_cleanup): Check for the presence of a
2662 vms_private_data_struct before examining any of its fields.
2664 2008-01-07 H.J. Lu <hongjiu.lu@intel.com>
2667 * elflink.c (elf_link_input_bfd): Don't write out a section if
2668 its output section is marked with SEC_NEVER_LOAD.
