================
Comment at: lib/Target/X86/X86ISelLowering.cpp:28754
       SDValue CondNew = DAG.getNode(ISD::XOR, DL, Cond.getValueType(), Cond,
-        DAG.getConstant(1, DL, Cond.getValueType()));
+        DAG.getConstant(APInt::getAllOnesValue(CondVT.getScalarSizeInBits()),
+                        DL, CondVT));
----------------
Why do we need getScalarSizeInBits() if we already know its i1?
