[PATCH][x86] Add missing intrinsics for vrcp14sd/ss instructions.

Mon, 08 May 2017 23:29:23 -0700 

Hi,

This patch adds missing intrinsics for VRCP14SD and VRCP14SS instructions:
_mm_mask_rcp14_sd
_mm_maskz_rcp14_sd
_mm_mask_rcp14_ss
_mm_maskz_rcp14_ss

These instructions and intrinsics are described in SDM Vol. 2C 5-487.

gcc/
        * config/i386/avx512fintrin.h (_mm_mask_rcp14_sd,
        _mm_maskz_rcp14_sd, _mm_mask_rcp14_ss,
        _mm_maskz_rcp14_ss): New intrinsics.
        * config/i386/i386-builtin.def (__builtin_ia32_rcp14sd_mask,
        __builtin_ia32_rcp14ss_mask): New builtins.
        * config/i386/sse.md (srcp14<mode>_mask): New pattern.

gcc/testsuite/
        * gcc.target/i386/avx512f-vrcp14sd-1.c: Test new intrinsics.
        * gcc.target/i386/avx512f-vrcp14sd-2.c: Ditto.
        * gcc.target/i386/avx512f-vrcp14ss-1.c: Ditto.
        * gcc.target/i386/avx512f-vrcp14ss-2.c: Ditto.

Thanks,
Julia
