Add support for generating and inserting build IDs into COFF binaries.
* peXXigen.c (pe_print_debugdata): New function: Displays the
contents of the debug directory and decodes codeview entries.
(_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out)
(_bfd_XXi_slurp_codeview_record, _bfd_XXi_write_codeview_record):
Add functions for reading and writing debugdir and codeview
records.
* libpei.h (_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out)
(_bfd_XXi_write_codeview_record): Add prototypes and macros.
* libcoff-in.h (pe_tdata): Add build-id data.
* libcoff.h: Regenerate.
* coffcode.h (coff_write_object_contents): Run build_id
after_write_object_contents hook.
* pe.h (external_IMAGE_DEBUG_DIRECTORY, _CV_INFO_PDB70)
(_CV_INFO_PDB20): Add structures and constants for debug directory
and codeview records.
* internal.h (internal_IMAGE_DEBUG_DIRECTORY, CODEVIEW_INFO):
Add structures and constants for internal representation of debug
directory and codeview records.
* emultempl/elf32.em (id_note_section_size, read_hex, write_build_id):
Move code for parsing build-id option and calculating the build-id to...
* ldbuildid.c: New file.
* ldbuildid.h: New file.
* Makefile.am (CFILES, HFILES, OFILES, ld_new_SOURCES): Add new
files.
* Makefile.in: Regenerate.
* ld.texinfo: Update --build-id description to mention COFF
support.
* NEWS: Mention support for COFF build ids.
* emultempl/pe.em (gld${EMULATION_NAME}_handle_option):
(pecoff_checksum_contents, write_build_id, setup_build_id)
(gld_${EMULATION_NAME}_after_open): Handle and implement
build-id option.
* emultempl/pep.em: Likewise.
