[PATCH] D48508: [DAGCombiner] eliminate setcc bool math when input is low-bit of some value

[Craig Topper via Phabricator via llvm-commits]

================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:2029
+      N0.getOperand(0).getOpcode() == ISD::SETCC &&
+      N0.getOperand(0).getValueSizeInBits() == 1) {
+    SDValue SetCC = N0.getOperand(0);
----------------
Why not "getValueType() == MVT::i1"?
