[MIPS/GAS] Split Loongson EXT Instructions from loongson3a.
bfd/ * elfxx-mips.c (infer_mips_abiflags): Use ases instead of isa_ext for infer ABI flags. (print_mips_ases): Add Loongson EXT extension. binutils/ * readelf.c (print_mips_ases): Add Loongson EXT extension. elfcpp/ * mips.h (AFL_ASE_LOONGSON_EXT): New enum. gas/ * NEWS: Mention Loongson EXTensions (EXT) support. * config/tc-mips.c (options): Add OPTION_LOONGSON_EXT and OPTION_NO_LOONGSON_EXT. (md_longopts): Likewise. (mips_ases): Define availability for EXT. (mips_convert_ase_flags): Map ASE_LOONGSON_EXT to AFL_ASE_LOONGSON_EXT. (mips_cpu_info_table): Add ASE_LOONGSON_EXT for loongson3a. (md_show_usage): Add help for -mloongson-ext and -mno-loongson-ext. * doc/as.texi: Document -mloongson-ext, -mno-loongson-ext. * doc/c-mips.texi: Document -mloongson-ext, -mno-loongson-ext, .set loongson-ext and .set noloongson-ext. * testsuite/gas/mips/loongson-mmi.d: Add ASE flag. include/ * elf/mips.h (AFL_ASE_LOONGSON_EXT): New macro. (AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_EXT. * opcode/mips.h (ASE_LOONGSON_EXT): New macro. opcodes/ * mips-dis.c (mips_arch_choices): Add EXT to loongson3a descriptors. (parse_mips_ase_option): Handle -M loongson-ext option. (print_mips_disassembler_options): Document -M loongson-ext. * mips-opc.c (IL3A): Delete. * mips-opc.c (LEXT): New macro. (mips_opcodes): Replace IL2F|IL3A marking with LEXT for EXT instructions.
