[PATCH] D135278: [VectorCombine] convert scalar fneg with insert/extract to vector fneg

[Thorsten via Phabricator via llvm-commits]

tschuett added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:563
+  SmallVector<int> Mask;
+  for (unsigned i = 0, e = VecTy->getNumElements(); i != e; ++i) {
+    if (i == Index)
----------------
Tiniest nit: You could `Mask.reserve(VecTy->getNumElements());`
