[PATCH] D34242: [InstCombine] canonicalize icmp predicate feeding select

[Davide Italiano via Phabricator via llvm-commits]

davide added a comment.

If the goal of this is to expose more opportunities for congruent expressions maybe GVN itself should do this canonicalization, maybe? Some algorithms perform, e.g., reassociation to catch more cases.
See, e.g.
