        * config/i386/i386.c (m_GOLDMONT): Define.
        (processor_target_table): Add "goldmont".
        (PTA_GOLDMONT): Define.
        (ix86_lea_outperforms): Add TARGET_GOLDMONT.
        (get_builtin_code_for_version): Handle PROCESSOR_GOLDMONT.

        * config/i386/i386.h (processor_costs): Define TARGET_GOLDMONT.
        (processor_type): Add PROCESSOR_GOLDMONT.
        * config/i386/i386.md: Add CPU "glm".
        * config/i386/glm.md: New file.
        * config/i386/x86-tune.def: Add m_GOLDMONT.
        * doc/invoke.texi: Add goldmont as x86 -march=/-mtune= CPU type.

libgcc/
        * config/i386/cpuinfo.h (processor_types): Add INTEL_GOLDMONT.
        * config/i386/cpuinfo.c (get_intel_cpu): Detect Goldmont.

gcc/testsuite/

        * gcc.target/i386/builtin_target.c: Test goldmont.

Is it OK?

Thanks.
