[MIPS/GAS] Add Loongson EXT2 Instructions support.
bfd/ * elfxx-mips.c (print_mips_ases): Add Loongson EXT2 extension. binutils/ * readelf.c (print_mips_ases): Add Loongson EXT2 extension. gas/ * NEWS: Mention Loongson EXTensions R2 (EXT2) support. * config/tc-mips.c (options): Add OPTION_LOONGSON_EXT2 and OPTION_NO_LOONGSON_EXT2. (md_longopts): Likewise. (mips_ases): Define availability for EXT. (mips_convert_ase_flags): Map ASE_LOONGSON_EXT2 to AFL_ASE_LOONGSON_EXT2. (md_show_usage): Add help for -mloongson-ext2 and -mno-loongson-ext2. * doc/as.texi: Document -mloongson-ext2, -mno-loongson-ext2. * doc/c-mips.texi: Document -mloongson-ext2, -mno-loongson-ext2, .set loongson-ext2 and .set noloongson-ext2. * testsuite/gas/mips/loongson-ext2.d: New test. * testsuite/gas/mips/loongson-ext2.s: New test. * testsuite/gas/mips/mips.exp: Run loongson-ext2 test. include/ * elf/mips.h (AFL_ASE_LOONGSON_EXT2): New macro. (AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_EXT2. * opcode/mips.h (ASE_LOONGSON_EXT2): New macro. opcodes/ * mips-dis.c (parse_mips_ase_option): Handle -M loongson-ext option. (print_mips_disassembler_options): Document -M loongson-ext. * mips-opc.c (LEXT2): New macro. (mips_opcodes): Add cto, ctz, dcto, dctz instructions.
