[patch] Remove redundant intrinsics

Mon, 04 Jun 2018 03:27:45 -0700 

Hi,

Since pre-Icelake ISA already had 128bit version vpclmul and vaes, we already 
have intrinsics for them(_mm_aesdec_si128, _mm_aesdeclast_si128, 
_mm_aesenc_si128, _mm_aesenclast_si128, _mm_clmulepi64_si128). Therefore 
intrinsics for them, introduced with Icelake instructions are redundant. This 
patch removes them. Ok for trunk?

gcc/
        * config/i386/vaesintrin.h (_mm_aesdec_epi128, _mm_aesdeclast_epi128,
        _mm_aesenc_epi128, _mm_aesenclast_epi128): Remove.
        * config/i386/vpclmulqdqintrin.h (_mm_clmulepi64_epi128): Remove.

gcc/testsuite/
        * gcc.target/i386/avx512fvl-vaes-1.c: Remove 128bit versions from test.
        * gcc.target/i386/vpclmulqdq.c: Ditto.

Thanks,
Julia
