[PATCH] D149199: [SelectionDAG] Fill in some more cases in `isKnownNeverZero`

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:5078
+    // The expression is really !Known.One[BitWidth-MaxLog2(Known):0].isZero()
+    if (computeKnownBits(Op.getOperand(0)).One[0], Depth + 1)
       return true;
