[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:7159
   Instruction *RetI = I;
-  if ((RetI->getOpcode() == Instruction::SExt ||
-       RetI->getOpcode() == Instruction::ZExt)) {
+  if (match(RetI, m_ZExtOrSExt(m_Value()))) {
     if (!RetI->hasOneUser())
----------------
