[Elena Demikhovsky via Phabricator via llvm-commits]

delena added inline comments.


================
Comment at: lib/Transforms/Vectorize/LoopVectorize.cpp:4710
+      if (Legal->isUniform(GEP)) {
+        auto *Clone = cast<GetElementPtrInst>(GEP->clone());
+        for (unsigned I = 0; I < GEP->getNumOperands(); ++I)
----------------
GEP is uniform when the memory instruction (User) is uniform, right?
Why do you need to broadcast it?
