[PATCH] D75808: [ValueTracking] isKnownNonZero, computeKnownBits for freeze

[Francois Pichet via Phabricator via llvm-commits]

fpichet added a comment.

Another thing: I noticed that SelectionDAG::computeKnownBits doesn't deal with ISD::FREEZE.
Would it be ok to just call computeKnownBits (Op.getOperand(0)) to make it work. 
(Since Select_FREEZE just lower to a copy)
