[PATCH] D102275: [x86] try to use PCMPGT instead of not-of-PCMPEQ

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Seems reasonable to me.



================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:23082-23084
+  // X != INT_MIN --> X > INT_MIN
+  // X != INT_MAX --> X < INT_MAX --> INT_MAX > X
+  // +X != 0 --> X > 0
----------------
I think this could be a bit more readable if it specified the u/s of the comparison predicates.
