(coff_compute_section_file_positions): Use unsigned int for target_index. Compare with bfd_coff_max_nscns. (bfd_coff_std_swap_table, ticoff0_swap_table, ticoff1_swap_table): Set a value for _bfd_coff_max_nscns. (header_bigobj_classid): New constant. (coff_bigobj_swap_filehdr_in, coff_bigobj_swap_filehdr_out) (coff_bigobj_swap_sym_in, coff_bigobj_swap_sym_out) (coff_bigobj_swap_aux_in, coff_bigobj_swap_aux_out): New functions. (bigobj_swap_table): New table. * libcoff.h: Regenerate. * coff-sh.c (bfd_coff_small_swap_table): Likewise. * coff-alpha.c (alpha_ecoff_backend_data): Add value for _bfd_coff_max_nscns. * coff-mips.c (mips_ecoff_backend_data): Likewise. * coff-rs6000.c (bfd_xcoff_backend_data) (bfd_pmac_xcoff_backend_data): Likewise. * coff64-rs6000.c (bfd_xcoff_backend_data) (bfd_xcoff_aix5_backend_data): Likewise. * targets.c (x86_64pe_bigobj_vec): Declare. * configure.in (x86_64pe_bigobj_vec): New vector. * configure: Regenerate. * config.bfd: Add bigobj object format for Windows targets. gas/ * config/tc-i386.c (use_big_obj): Declare. (OPTION_MBIG_OBJ): Define. (md_longopts): Add -mbig-obj option. (md_parse_option): Handle it. (md_show_usage): Display help for this option. (i386_target_format): Use bigobj for x86-64 if -mbig-obj. * doc/c-i386.texi: Document the option. gas/testsuite/ * gas/pe/big-obj.d, gas/pe/big-obj.s: Add test. * gas/pe/pe.exp: Add test. include/coff/ * pe.h (struct external_ANON_OBJECT_HEADER_BIGOBJ): Declare.
