Sanjay Patel 3c3cd10928 merge consecutive stores of extracted vector elements ... Add a path to DAGCombiner::MergeConsecutiveStores() to combine multiple scalar stores when the store operands are extracted vector elements. This is a partial fix for PR21711 ( http://llvm.org/bugs/show_bug.cgi?id=21711 ). For the new test case, codegen improves from: vmovss %xmm0, (%rdi) vextractps $1, %xmm0, 4(%rdi) vextractps $2, %xmm0, 8(%rdi) vextractps $3, %xmm0, 12(%rdi) vextractf128 $1, %ymm0, %xmm0 vmovss %xmm0, 16(%rdi) vextractps $1, %xmm0, 20(%rdi) vextractps $2, %xmm0, 24(%rdi) vextractps $3, %xmm0, 28(%rdi) vzeroupper retq To: vmovups %ymm0, (%rdi) vzeroupper retq Patch reviewed by Nadav Rotem.
