================
Comment at: lib/CodeGen/SelectionDAG/LegalizeIntegerTypes.cpp:1327
+  // Promote the RETURNADDR/FRAMEADDR argument to a supported integer width.
+  SDValue Op = GetPromotedInteger(N->getOperand(0));
+  return SDValue(DAG.UpdateNodeOperands(N, Op), 0);
----------------
Not that it actually affects the generated code, but it would probably be more clear to use ZExtPromotedInteger.
