[PATCH] D104472: [ValueTracking] look through bitcast of vector in computeKnownBits

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Would it please be possible to either enhance comments, or port more comments from the `SelectionDAG::computeKnownBits()`?
It appears to match that original implementation, and seems correct, but it is hard to read/get through.
