[PATCH] D133430: [SLP] Unify main/alternate instruction logic for CmpInst instructions - draft

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:582-586
-        auto *AltInst = cast<CmpInst>(VL[AltIndex]);
-        CmpInst::Predicate AltPred = AltInst->getPredicate();
-        if (BasePred == CurrentPred || BasePred == SwappedCurrentPred ||
-            AltPred == CurrentPred || AltPred == SwappedCurrentPred)
-          continue;
----------------
Why did you removed this check? I believe it might help to build some nodes, though terminating with gathers.
