2646 * elf32-fr30.c (fr30_elf_howto_table): Set partial_inplace field
2647 to FALSE for all relocs.
2649 2008-01-09 Richard Sandiford <rsandifo@nildram.co.uk>
2652 * elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
2653 fields. Rename u.cie.u.merged to u.cie.u.merged_with.
2654 (eh_frame_sec_info): Add a cies field.
2655 (eh_frame_hdr_info): Add a merge_cies field.
2656 * elf-eh-frame.c (cie): Add a reloc_index member to the personality
2658 (_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
2660 (_bfd_elf_parse_eh_frame): Remove tmp_cie. Ccreate an array of
2661 cie structures in all cases and use it instead of extended_cies.
2662 If merging, store the cie array in sec_info->cies and point each
2663 CIE's eh_fde_cie at the associated element. Do not try to
2664 calculate the value of the personality routine here; record the
2665 offset of the relocation instead. Do not merge CIEs here.
2666 (_bfd_elf_end_eh_frame_parsing): Do not free hdr_info->cies here...
2667 (_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
2668 (_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
2669 (find_merged_cie): New function.
2670 (_bfd_elf_gc_mark_fdes): Use it. Free sec_info->cies.

2675 * vms.c (vms_close_and_cleanup): Check for the presence of a
2676 vms_private_data_struct before examining any of its fields.
2678 2008-01-07 H.J. Lu <hongjiu.lu@intel.com>
2681 * elflink.c (elf_link_input_bfd): Don't write out a section if
2682 its output section is marked with SEC_NEVER_LOAD.
