================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:3107
+  // If VFxUF is 2 and vector loop is not skipped then remainder executes once.
+  if (VF * UF == 2 && !areSafetyChecksAdded()) {
+    if (BasicBlock *Latch = OrigLoop->getLoopLatch())
----------------
I think this check is enough unless there are other cases in which "remainder loop has `N % (VF*UF)` iterations doesn't hold.
