[PATCH] D144895: [SLP] Fixes crash in BoUpSLP::isGatherShuffledEntry()

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:8410-8411
       // Clear undef scalars.
-      for (int I = 0, Sz = VL.size(); I < Sz; ++I)
+      for (int I = 0, Sz = TE->Scalars.size(); I < Sz; ++I)
         if (isa<PoisonValue>(TE->Scalars[I]))
           Mask[I] = UndefMaskElem;
----------------
Better to replace `TE->Scalars[I]` with `VL[I]`
