[PATCH] D78582: [InstCombine] substitute equivalent constant to reduce logic-of-icmps

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added a comment.

I like this approach too because it is simpler.
Is it possible to apply this approach to InstSimplify as well? For example, when (x == c && x < y) is given, we can recursively call simplify icmp of (ult, c, y) and return its result.
