(_bfd_write_merged_section): New. (_bfd_merged_section_offset): New. * libbfd.h: Rebuilt. * linker.c (_bfd_generic_link_output_symbols): Handle discard_sec_merge. * aoutx.h (aout_link_write_symbols): Likewise. * pdp11.c (aout_link_write_symbols): Likewise. * elflink.h (elf_link_add_object_symbols): Call _bfd_merge_section. (elf_bfd_final_link): Adjust global symbols pointing into SEC_MERGE sections. (elf_link_sec_merge_syms): New. (elf_link_input_bfd): Call _bfd_merged_section_offset and _bfd_write_merged_section. Handle discard_sec_merge. * elf-bfd.h (struct elf_link_hash_table): Add merge_info field. (struct bfd_elf_section_data): Likewise. * elf.c (_bfd_elf_make_section_from_shdr): Set SEC_MERGE and SEC_STRINGS section flags and entsize from their ELF counterparts. (_bfd_elf_link_hash_table_init): Initialize merge_info. (elf_fake_sections): Set SHF_MERGE, SHF_STRINGS and sh_entsize from their BFD counterparts. * merge.c: New file. * Makefile.am: Add strtab.lo. * Makefile.in: Rebuilt. include/ * bfdlink.h (bfd_link_discard): Add discard_sec_merge. gas/ * config/obj-elf.c (obj_elf_change_section): Add entsize argument, handle SHF_MERGE and SHF_STRINGS. (obj_elf_parse_section_letters): Set SHF_MERGE and SHF_STRINGS. (obj_elf_section): Allow additional argument specifying entity size. * write.c (adjust_reloc_syms): Keep relocations against local symbols in SEC_MERGE sections. ld/ * ldmain.c (main): Default to discard_sec_merge. * lexsup.c (OPTION_DISCARD_NONE): Define. (ld_options): Add --discard-none. (parse_args): Handle OPTION_DISCARD_NONE. * ldlang.c (wild_doit): SEC_MERGE should be set in the output section only if SEC_MERGE and SEC_STRINGS flags and entsize of all its input sections match. --- bfd/libbfd-in.h | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'bfd/libbfd-in.h') diff --git a/bfd/libbfd-in.h b/bfd/libbfd-in.h index dc2cd11..dae7635 100644 --- a/bfd/libbfd-in.h +++ b/bfd/libbfd-in.h @@ -462,6 +462,21 @@ extern boolean _bfd_write_stab_strings PARAMS ((bfd *, PTR *)); extern bfd_vma _bfd_stab_section_offset PARAMS ((bfd *, PTR *, asection *, PTR *, bfd_vma)); +/* Attempt to merge a SEC_MERGE section. */ + +extern boolean _bfd_merge_section + PARAMS ((bfd *, PTR *, asection *, PTR *)); + +/* Write out a merged section. */ + +extern boolean _bfd_write_merged_section + PARAMS ((bfd *, asection *, PTR)); + +/* Find an offset within a modified SEC_MERGE section. */ + +extern bfd_vma _bfd_merged_section_offset + PARAMS ((bfd *, asection **, PTR, bfd_vma, bfd_vma)); + /* Create a string table. */ extern struct bfd_strtab_hash *_bfd_stringtab_init PARAMS ((void)); -- cgit v1.1
