Fix 11769. In CanXFormVExtractWithShuffleIntoLoad we assumed that EXTRACT_VECTOR_ELT can be later handled by the DAGCombiner. However, in some cases on AVX, the EXTRACT_VECTOR_ELT is legalized to EXTRACT_SUBVECTOR + EXTRACT_VECTOR_ELT, which currently is not handled by the DAGCombiner. In this patch I added a check that we only extract from the XMM part. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148298 91177308-0d34-0410-b5e6-96231b3b80d8
