Andrea Di Biagio 5d0ff9c928 [X86] Add ISel patterns to select SSE3/AVX ADDSUB instructions. ... This patch adds ISel patterns to select SSE3/AVX ADDSUB instructions from a sequence of "vadd + vsub + blend". Example: /// typedef float float4 __attribute__((ext_vector_type(4))); float4 foo(float4 A, float4 B) { float4 X = A - B; float4 Y = A + B; return (float4){X[0], Y[1], X[2], Y[3]}; } /// Before this patch, (with flag -mcpu=corei7) llc produced the following assembly sequence: movaps %xmm0, %xmm2 addps %xmm1, %xmm2 subps %xmm1, %xmm0 blendps $10, %xmm2, %xmm0 With this patch, we now get a single addsubps %xmm1, %xmm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211427 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-21 01:31:15 +00:00
