Michael Kuperstein 1f0ddef593 [DagCombine] Improve DAGCombiner BUILD_VECTOR when it has two sources of elements ... This partially fixes PR21943. For AVX, we go from: vmovq (%rsi), %xmm0 vmovq (%rdi), %xmm1 vpermilps $-27, %xmm1, %xmm2 ## xmm2 = xmm1[1,1,2,3] vinsertps $16, %xmm2, %xmm1, %xmm1 ## xmm1 = xmm1[0],xmm2[0],xmm1[2,3] vinsertps $32, %xmm0, %xmm1, %xmm1 ## xmm1 = xmm1[0,1],xmm0[0],xmm1[3] vpermilps $-27, %xmm0, %xmm0 ## xmm0 = xmm0[1,1,2,3] vinsertps $48, %xmm0, %xmm1, %xmm0 ## xmm0 = xmm1[0,1,2],xmm0[0] To the expected: vmovq (%rdi), %xmm0 vmovhpd (%rsi), %xmm0, %xmm0 retq Fixing this for AVX2 is still open.
