[MIPS/GAS] Split Loongson CAM Instructions from loongson3a
bfd/
* elfxx-mips.c (print_mips_ases): Add CAM extension.
binutils/
* readelf.c (print_mips_ases): Add CAM extension.
gas/
* NEWS: Mention Loongson Content Address Memory (CAM)
support.
* config/tc-mips.c (options): Add OPTION_LOONGSON_CAM and
OPTION_NO_LOONGSON_CAM.
(md_longopts): Likewise.
(mips_ases): Define availability for CAM.
(mips_convert_ase_flags): Map ASE_LOONGSON_CAM to
AFL_ASE_LOONGSON_CAM.
(mips_cpu_info_table): Add ASE_LOONGSON_CAM for loongson3a.
(md_show_usage): Add help for -mloongson-cam and
-mno-loongson-cam.
* doc/as.texi: Document -mloongson-cam, -mno-loongson-cam.
* doc/c-mips.texi: Document -mloongson-cam, -mno-loongson-cam,
.set loongson-cam and .set noloongson-cam.
* testsuite/gas/mips/loongson-3a-2.d: Move cam test to ...
* testsuite/gas/mips/loongson-cam.d: Here. Add ISA/ASE
flag verification.
* testsuite/gas/mips/loongson-3a-2.s: Move cam test to ...
* testsuite/gas/mips/loongson-cam.s: Here.
* testsuite/gas/mips/loongson-3a-mmi.d: Add ASE flag.
* testsuite/gas/mips/mips.exp: Run loongson-cam test.
include/
* elf/mips.h (AFL_ASE_LOONGSON_CAM): New macro.
(AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_CAM.
* opcode/mips.h (ASE_LOONGSON_CAM): New macro.
opcodes/
* mips-dis.c (mips_arch_choices): Add CAM to loongson3a
descriptors.
(parse_mips_ase_option): Handle -M loongson-cam option.
(print_mips_disassembler_options): Document -M loongson-cam.
* mips-opc.c (LCAM): New macro.
(mips_opcodes): Replace IL2F|IL3A marking with LCAM for CAM
instructions.
