(bfd_coff_force_symnames_in_strings, bfd_coff_debug_string_prefix_length): New macros for above fields. * coffcode.h (coff_set_arch_mach_hook): Handle XCOFF64 magic. Set machine to 620 for XCOFF64. Use bfd_coff_swap_sym_in instead of using coff_swap_sym_in directly. (FORCE_SYMNAMES_IN_STRINGS): New macro, defined for XCOFF64. (coff_set_flags) Set magic for XCOFF64. (coff_compute_section_file_positions): Add symbol name length to string section length if bfd_coff_debug_string_prefix_length is true. (coff_write_object_contents): Don't do reloc overflow for XCOFF64. (coff_slurp_line_table): Use bfd_coff_swap_lineno_in instead of using coff_swap_lineno_in directly. (bfd_coff_backend_data): Add _bfd_coff_force_symnames_in_strings and _bfd_coff_debug_string_prefix_length fields. * coffgen.c (coff_fix_symbol_name, coff_write_symbols): Force symbol names into strings table when bfd_coff_force_symnames_in_strings is true. * coffswap.h (MAX_SCNHDR_NRELOC, MAX_SCNHDR_NLNNO, GET_RELOC_VADDR, SET_RELOC_VADDR): New macros. (coff_swap_reloc_in, coff_swap_reloc_out): Use above macros. (coff_swap_aux_in, coff_swap_aux_out): Remove RS6000COFF_C code. (coff_swap_aouthdr_in, coff_swap_aouthdr_out): Handle XCOFF64 changes within RS6000COFF_C specific code. (coff_swap_scnhdr_out): Use PUT_SCNHDR_NLNNO, PUT_SCNHDR_NRELOC, MAX_SCNHDR_NRELOC, and MAX_SCNHDR_NLNNO. * reloc.c (bfd_perform_relocation, bfd_install_relocation): Extend existing hack on target name. * xcofflink.c (XCOFF_XVECP): Extend existing hack on target name. * coff-tic54x.c (ticof): Keep up to date with new fields in bfd_coff_backend_data. * config.bfd: Add bfd_powerpc_64_arch to targ_arch and define targ_selvecs to include rs6000coff64_vec for rs6000. * configure.in: Add rs6000coff64_vec case. * cpu-powerpc.c: New bfd_arch_info_type. gas: * as.c (parse_args): Allow md_parse_option to override -a listing option. * config/obj-coff.c (add_lineno): Change type of offset parameter from "int" to "bfd_vma." * config/tc-ppc.c (md_pseudo_table): Add "llong" and "machine." (ppc_mach, ppc_subseg_align, ppc_target_format): New. (ppc_change_csect): Align correctly for XCOFF64. (ppc_machine): New function, which discards "ppc_machine" line. (ppc_tc): Cons for 8 when code is 64 bit. (md_apply_fix3): Don't check operand->insert. Handle 64 bit relocations. (md_parse_option): Handle -a64 and -a32. (ppc_xcoff64): New. * config/tc-ppc.h (TARGET_MACH): Define. (TARGET_FORMAT): Move to function. (SUB_SEGMENT_ALIGN): Use ppc_subseg_align. include: * include/coff/rs6k64.h: New file. opcodes: * configure.in: Add bfd_powerpc_64_arch. * disassemble.c (disassembler): Use print_insn_big_powerpc for 64 bit code.
