Done.



================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeTypesGeneric.cpp:211
   SDValue OldVec = N->getOperand(0);
-  unsigned OldElts = OldVec.getValueType().getVectorNumElements();
+  auto OldEltCount = OldVec.getValueType().getVectorElementCount();
   EVT OldEltVT = OldVec.getValueType().getVectorElementType();
