[PATCH] D149195: [SelectionDAG] Limit max recursion in `isKnownNeverZero` and `isKnownToBeAPowerOfTwo`

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:5014-5015
   case ISD::OR:
     if (isKnownNeverZero(Op.getOperand(1)) ||
         isKnownNeverZero(Op.getOperand(0)))
       return true;
----------------
Need to pass Depth into the recursive calls, otherwise what's the point?
