[PATCH] D101074: [X86] Canonicalize LT/GT compares with constants to use LE/GE to reduce the number of EFLAGs reads. (PR48760)

RKSimon added a comment.

The equivalent less-than fold to reduce EFLAGS dependency is SLE/ULE -> SLT/ULT - which we don't typically need to do because TargetLowering.SimplifySetCC already canonicalizes to that - sorry I was on automatic when was asked to support SLT/ULT (and it'd been far too long since I looked at the patch...)
