[PATCH] D144292: [SLP] Fix infinite loop in isUndefVector.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:379
+          return Res.reset();
         Base = II->getOperand(0);
         std::optional<unsigned> Idx = getInsertIndex(II);
----------------
Move `Base = II->getOperand(0);` before the if statement instead, it is not an error path
