[PATCH] D133017: [LV] Use SCEV to check if the trip count <= VF * UF.

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/VPlanTransforms.cpp:469
+  if (ExitCount->isZero() ||
+      !SE.isKnownPredicate(CmpInst::ICMP_ULE, ExitCount, C))
     return;
----------------
Could this be simplified using SE.getSmallConstantMaxTripCount(L)? Or a caching thereof.
