RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:10156
+    return DAG.getNode(ISD::ABDS, SDLoc(N), VT, N->getOperand(0).getOperand(0),
+                       N->getOperand(0).getOperand(1));
+
----------------
Worth moving this inside combineABSToABD?
