[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.
