[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:4302
+        if (!Res && KnownRHS.isZero() && DAG.isKnownNeverZero(N0))
+          Res = false;
+        break;
----------------
I'm not sure this is always false?
