        * 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.

        -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.
