(struct elf_backend_data): Add elf_backend_reloc_type_class. (_bfd_elf_reloc_type_class): New. * elfxx-target.h (elf_backend_reloc_type_class): Define. (elfNN_bed): Add elf_backend_reloc_type_class. * elf.c (_bfd_elf_reloc_type_class): New. * elf32-i386.c (elf_i386_check_relocs): Set DF_TEXTREL if the reloc is against read-only section. (elf_i386_size_dynamic_sections): Use DF_TEXTREL flag instead of looking up section names for DT_TEXTREL. (elf_i386_reloc_type_class): New. (elf_backend_reloc_type_class): Define. * elf32-sparc.c (elf32_sparc_check_relocs): Set DF_TEXTREL if the reloc is against read-only section. (elf32_sparc_size_dynamic_sections): Use DF_TEXTREL flag instead of looking up section names for DT_TEXTREL. (elf32_sparc_reloc_type_class): New. (elf_backend_reloc_type_class): Define. * elf64-sparc.c (sparc64_elf_check_relocs): Set DF_TEXTREL if the reloc is against read-only section. (sparc64_elf_size_dynamic_sections): Use DF_TEXTREL flag instead of looking up section names for DT_TEXTREL. (sparc64_elf_reloc_type_class): New. (elf_backend_reloc_type_class): Define. * elfxx-ia64.c (struct elfNN_ia64_link_hash_table): Add reltext field. (elfNN_ia64_hash_table_create): Clear ia64_info. (get_reloc_section): Set DF_TEXTREL if the reloc is against read-only section. (elfNN_ia64_size_dynamic_sections): Use ia64_info->reltext flag instead of looking up section names for DT_TEXTREL. (elfNN_ia64_reloc_type_class): New. (elf_backend_reloc_type_class): Define. * elflink.h (size_dynamic_sections): Add spare DT_NULL tags. (struct elf_link_sort_rela): New. (elf_link_sort_cmp1, elf_link_sort_cmp2, elf_link_sort_relocs): New. (elf_bfd_final_link): Call elf_link_sort_relocs. Convert one spare DT_NULL into DT_RELCOUNT resp. DT_RELACOUNT if necessary. * bfdlink.h (struct bfd_link_info): Add combreloc and spare_dynamic_tags fields. * emultempl/elf32.em (place_orphan): Place orphan .rel* sections into .rel.dyn resp. .rela.dyn if combreloc. (get_script): If .x linker script is equal to .xn, only put it once into the binary. Add .xc and .xsc scripts. (parse_args): Handle -z combreloc and -z nocombreloc. * scripttempl/elf.sc (.rela.sbss): Fix a typo. For .xc and .xsc scripts put all .rel* or .rela* input sections but .rel*.plt and PLT-like sections into .rel.dyn resp. .rela.dyn. * genscripts.sh (GENERATE_COMBRELOC_SCRIPT): Set if SCRIPT_NAME is elf. Strip trailing whitespace from script. Generate .xc and .xsc scripts if requested. * ldmain.c (main): Initialize link_info.combreloc and link_info.spare_dynamic_tags. * lexsup.c (OPTION_SPARE_DYNAMIC_TAGS): Define. (ld_options): Add --spare-dynamic-tags option. (parse_args): Likewise. * ld.texinfo: Document -z combreloc and -z nocombreloc. * ldint.texinfo: Document .xc and .xsc linker scripts. * NEWS: Add notes about -z combreloc and SHF_MERGE. --- bfd/elfxx-target.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'bfd/elfxx-target.h') diff --git a/bfd/elfxx-target.h b/bfd/elfxx-target.h index 6ba5b6e..a4c5e1d 100644 --- a/bfd/elfxx-target.h +++ b/bfd/elfxx-target.h @@ -339,6 +339,9 @@ Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. */ #ifndef elf_backend_fprintf_vma #define elf_backend_fprintf_vma _bfd_elf_fprintf_vma #endif +#ifndef elf_backend_reloc_type_class +#define elf_backend_reloc_type_class _bfd_elf_reloc_type_class +#endif /* Previously, backends could only use SHT_REL or SHT_RELA relocation sections, but not both.
