Hal Finkel 90adf0fe06 Make use of previously generated stores in SelectionDAGLegalize::ExpandExtractFromVectorThroughStack ... When expanding EXTRACT_VECTOR_ELT and EXTRACT_SUBVECTOR using SelectionDAGLegalize::ExpandExtractFromVectorThroughStack, we store the entire vector and then load the piece we want. This is fine in isolation, but generating a new store (and corresponding stack slot) for each extraction ends up producing code of poor quality. When we scalarize a vector operation (using SelectionDAG::UnrollVectorOp for example) we generate one EXTRACT_VECTOR_ELT for each element in the vector. This used to generate one stored copy of the vector for each element in the vector. Now we search the uses of the vector for a suitable store before generating a new one, which results in much more efficient scalarization code. llvm-svn: 205153		2014-03-30 15:10:18 +00:00
