(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. --- include/ChangeLog | 5 +++++ include/bfdlink.h | 9 ++++++++- 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/include/ChangeLog b/include/ChangeLog index 802596606..55f85ad06 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,3 +1,8 @@ +2001-08-23 Jakub Jelinek + + * bfdlink.h (struct bfd_link_info): Add combreloc and + spare_dynamic_tags fields. + 2001-08-23 Lars Brinkhoff * dyn-string.h, fibheap.h, partition.h, sort.h, splay-tree.h: diff --git a/include/bfdlink.h b/include/bfdlink.h index 56b1fe458..1dd284238 100644 --- a/include/bfdlink.h +++ b/include/bfdlink.h @@ -275,9 +275,16 @@ struct bfd_link_info /* May be used to set DT_FLAGS_1 for ELF. */ bfd_vma flags_1; - /* true if auto-import thunks for DATA items in pei386 DLLs + /* True if auto-import thunks for DATA items in pei386 DLLs should be generated/linked against. */ boolean pei386_auto_import; + + /* True if non-PLT relocs should be merged into one reloc section + and sorted so that relocs against the same symbol come together. */ + boolean combreloc; + + /* How many spare .dynamic DT_NULL entries should be added? */ + int spare_dynamic_tags; }; /* This structures holds a set of callback functions.
