[PATCH] D55822: [SelectionDAG] Optional handling of UNDEF elements in matchBinaryPredicate

[Andrea Di Biagio via Phabricator via llvm-commits]

andreadb added a comment.

As I wrote to D55819 <https://reviews.llvm.org/D55819>, I think this is a nice improvement and makes the matching logic resilient to the presence of undefs in the input vectors. It also fixes the regression introduced by D55600 <https://reviews.llvm.org/D55600> in @knownbits_mask_or_shuffle_uitofp. So, overall, I think this is a nice improvement.
