Introduce new section flag: SEC_ELF_OCTETS
All symbols, sizes and relocations in this section are octets instead of bytes. Required for DWARF debug sections as DWARF information is organized in octets, not bytes. bfd/ * section.c (struct bfd_section): New flag SEC_ELF_OCTETS. * archures.c (bfd_octets_per_byte): New parameter sec. If section is not NULL and SEC_ELF_OCTETS is set, one octet es returned [ELF targets only]. * bfd.c (bfd_get_section_limit): Provide section parameter to bfd_octets_per_byte. * bfd-in2.h: regenerate. * binary.c (binary_set_section_contents): Move call to bfd_octets_per_byte into section loop. Provide section parameter to bfd_octets_per_byte. * coff-arm.c (coff_arm_reloc): Provide section parameter to bfd_octets_per_byte. * coff-i386.c (coff_i386_reloc): likewise. * coff-mips.c (mips_reflo_reloc): likewise. * coff-x86_64.c (coff_amd64_reloc): likewise. * cofflink.c (_bfd_coff_link_input_bfd): likewise.

Set SEC_ELF_OCTETS for sections with names .gnu.build.attributes, .debug*, .zdebug* and .note.gnu*. * elf32-msp430.c (rl78_sym_diff_handler): Provide section parameter to bfd_octets_per_byte. * elf32-nds.c (nds32_elf_get_relocated_section_contents): likewise. * elf32-ppc.c (ppc_elf_addr16_ha_reloc): likewise. * elf32-pru.c (pru_elf32_do_ldi32_relocate): likewise. * elf32-s12z.c (opru18_reloc): likewise. * elf32-sh.c (sh_elf_reloc): likewise. * elf32-spu.c (spu_elf_rel9): likewise. * elf32-xtensa.c (bfd_elf_xtensa_reloc): likewise * elf64-ppc.c (ppc64_elf_brtaken_reloc): likewise.

(bfd_install_relocation): likewise. For section which have SEC_ELF_OCTETS set, multiply output_base and output_offset with bfd_octets_per_byte. (bfd_perform_relocation): likewise. include/ * coff/ti.h (GET_SCNHDR_SIZE, PUT_SCNHDR_SIZE, GET_SCN_SCNLEN), (PUT_SCN_SCNLEN): Adjust bfd_octets_per_byte calls. binutils/ * objdump.c (disassemble_data): Provide section parameter to bfd_octets_per_byte. (dump_section): likewise (dump_section_header): likewise. Show SEC_ELF_OCTETS flag if set. gas/ * as.h: Define SEC_OCTETS as SEC_ELF_OCTETS if OBJ_ELF. * dwarf2dbg.c: (dwarf2_finish): Set section flag SEC_OCTETS for .debug_line, .debug_info, .debug_abbrev, .debug_aranges, .debug_str and .debug_ranges sections. * write.c (maybe_generate_build_notes): Set section flag SEC_OCTETS for .gnu.build.attributes section. * frags.c (frag_now_fix): Don't divide by OCTETS_PER_BYTE if SEC_OCTETS is set. * symbols.c (resolve_symbol_value): Likewise. ld/ * ldexp.c (fold_name): Provide section parameter to bfd_octets_per_byte. * ldlang (init_opb): New argument s.

(lang_size_sections_1,lang_size_sections_1, lang_do_assignments_1): Likewise. (lang_process): Pass NULL to init_opb.
