(read_hex, _bfd_elf_write_build_id_section): New static functions. (_bfd_elf_write_object_contents): Call _bfd_elf_write_build_id_section if emit_note_gnu_build_id is set. * Makefile.am (elf.lo): Update dependencies. * elf-bfd.h (struct elf_size_info): Add checksum_contents hook. (bfd_elf32_checksum_contents, bfd_elf64_checksum_contents): Declare. * elfcode.h (elf_checksum_contents): New macro and function. (NAME(_bfd_elf,size_info)): Initialize checksum_contents hook. --- bfd/elf-bfd.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/bfd/elf-bfd.h b/bfd/elf-bfd.h index f7fba9dcf11..7e3592ee4f4 100644 --- a/bfd/elf-bfd.h +++ b/bfd/elf-bfd.h @@ -448,6 +448,8 @@ struct elf_size_info { (bfd *, const Elf_Internal_Phdr *, unsigned int); bfd_boolean (*write_shdrs_and_ehdr) (bfd *); + bfd_boolean (*checksum_contents) + (bfd * , void (*) (const void *, size_t, void *), void *); void (*write_relocs) (bfd *, asection *, void *); bfd_boolean (*swap_symbol_in) @@ -1466,6 +1468,10 @@ struct elf_obj_tdata obj_attribute known_obj_attributes[2][NUM_KNOWN_OBJ_ATTRIBUTES]; obj_attribute_list *other_obj_attributes[2]; + + /* The .note.gnu.build-id section and --build-id option setting, or NULL. */ + char *emit_note_gnu_build_id; + asection *note_gnu_build_id_sec; }; #define elf_tdata(bfd) ((bfd) -> tdata.elf_obj_data) @@ -1869,6 +1875,8 @@ extern bfd_boolean bfd_elf32_write_shdrs_and_ehdr (bfd *); extern int bfd_elf32_write_out_phdrs (bfd *, const Elf_Internal_Phdr *, unsigned int); +extern bfd_boolean bfd_elf32_checksum_contents + (bfd * , void (*) (const void *, size_t, void *), void *); extern void bfd_elf32_write_relocs (bfd *, asection *, void *); extern bfd_boolean bfd_elf32_slurp_reloc_table @@ -1911,6 +1919,8 @@ extern bfd_boolean bfd_elf64_write_shdrs_and_ehdr (bfd *); extern int bfd_elf64_write_out_phdrs (bfd *, const Elf_Internal_Phdr *, unsigned int); +extern bfd_boolean bfd_elf64_checksum_contents + (bfd * , void (*) (const void *, size_t, void *), void *); extern void bfd_elf64_write_relocs (bfd *, asection *, void *); extern bfd_boolean bfd_elf64_slurp_reloc_table @@ -2036,6 +2046,9 @@ extern int _bfd_elf_obj_attrs_arg_type (bfd *, int, int); extern void _bfd_elf_parse_attributes (bfd *, Elf_Internal_Shdr *); extern bfd_boolean _bfd_elf_merge_object_attributes (bfd *, bfd *); +extern bfd_size_type _bfd_id_note_section_size + (bfd *abfd, struct bfd_link_info *link_info); + /* Large common section. */ extern asection _bfd_elf_large_com_section; -- 2.30.2
