================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:18266
+        NewVT = EVT::getVectorVT(Ctx, N1SrcSVT, NumElts * Scale);
+        NewIdx = DAG.getIntPtrConstant(InsIdx * Scale, DL);
+      } else if ((N1SrcSVT.getSizeInBits() % EltSizeInBits) == 0) {
----------------
Should use getVectorIdxTy?
