[PATCH] D146694: [NFC] Fix auto usage to avoid copies

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:20966
         bool Merged = true;
-        for (auto I : enumerate(Ops)) {
+        for (auto const& I : enumerate(Ops)) {
           SDValue &Op = I.value();
----------------
Doesn't the deference operator for enumerate return by value?
