[PATCH] D53876: Preserve loop metadata when splitting exit blocks

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: lib/Transforms/Utils/LoopUtils.cpp:78
+        // Switch-like insts may have duplicate edges.
+        if (!PushedBlocks.count(PredBB)) {
+          InLoopPredecessors.push_back(PredBB);
----------------
Can we use 'if (PushBlocks.insert(PredBB).second)'
