Elena Demikhovsky 3251020738 This patch optimizes shuffle instruction - generates 2 instructions instead of 4. ... Since this specific shuffle is widely used in many workloads we have ~10% performance on them. shufflevector <8 x float> %A, <8 x float> %B, <8 x i32> <i32 0, i32 8, i32 2, i32 10, i32 4, i32 12, i32 6, i32 14> vmovaps (%rdx), %ymm0 vshufps $8, %ymm0, %ymm0, %ymm0 vmovaps (%rcx), %ymm1 vshufps $8, %ymm0, %ymm1, %ymm1 vunpcklps %ymm0, %ymm1, %ymm0 vmovaps (%rcx), %ymm0 vmovsldup (%rdx), %ymm1 vblendps $85, %ymm0, %ymm1, %ymm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163134 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-04 12:49:02 +00:00
