        * config/i386/i386-builtin.def (__builtin_ia32_xgetbv,
        __builtin_ia32_xsetbv): New builtins.
        * config/i386/i386.c (ix86_expand_special_args_builtin): Process new

        (ix86_expand_builtin): Special expand for new intrinsics.
        * config/i386/i386.md: (UNSPECV_XGETBV, UNSPECV_XSETBV): New.
        (xsetbv, xsetbv_rex64, xgetbv, xgetbv_rex64): New patterns.
        * config/i386/xsaveintrin.h (_xsetbv, _getbv): New intrinsics.
