================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeVectorTypes.cpp:5131
 
+SDValue DAGTypeLegalizer::WidenVecRes_AssertZext(SDNode *N) {
+  SDValue InOp = GetWidenedVector(N->getOperand(0));
----------------
The extra elements added by widening aren’t guaranteed to satisfy the Asserted property.
