Elena Demikhovsky 832f074a32 Shuffle optimization for AVX/AVX2. ... The current patch optimizes frequently used shuffle patterns and gives these instruction sequence reduction. Before: vshufps $-35, %xmm1, %xmm0, %xmm2 ## xmm2 = xmm0[1,3],xmm1[1,3] vpermilps $-40, %xmm2, %xmm2 ## xmm2 = xmm2[0,2,1,3] vextractf128 $1, %ymm1, %xmm1 vextractf128 $1, %ymm0, %xmm0 vshufps $-35, %xmm1, %xmm0, %xmm0 ## xmm0 = xmm0[1,3],xmm1[1,3] vpermilps $-40, %xmm0, %xmm0 ## xmm0 = xmm0[0,2,1,3] vinsertf128 $1, %xmm0, %ymm2, %ymm0 After: vshufps $13, %ymm0, %ymm1, %ymm1 ## ymm1 = ymm1[1,3],ymm0[0,0],ymm1[5,7],ymm0[4,4] vshufps $13, %ymm0, %ymm0, %ymm0 ## ymm0 = ymm0[1,3,0,0,5,7,4,4] vunpcklps %ymm1, %ymm0, %ymm0 ## ymm0 = ymm0[0],ymm1[0],ymm0[1],ymm1[1],ymm0[4],ymm1[4],ymm0[5],ymm1[5] llvm-svn: 159188		2012-06-26 08:04:10 +00:00
