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

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:4027
   // Fall back to computeKnownBits to catch other known cases.
   KnownBits Known = computeKnownBits(Val);
   return (Known.countMaxPopulation() == 1) && (Known.countMinPopulation() == 1);
----------------
This is missing a depth too?
