[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:4105
+    SmallPtrSet<PHINode *, 2> ToFix;
+    PHINode *Phi = cast<PHINode>(PhiR->getUnderlyingValue());
+    for (User *U : Phi->users())
----------------
auto *Phi


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:4107
+    for (User *U : Phi->users())
+      if (isa<PHINode>(U) && cast<Instruction>(U)->getParent() == LoopExitBlock)
+        ToFix.insert(cast<PHINode>(U));
----------------
if (auto *UPhi = dyn_cast<PHINode>(U); UPhi && UPhi->getParent() == LoopExitBlock)
