[PATCH] D93906: [LoopDeletion] Break backedge of loops when known not taken

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/LoopUtils.cpp:774
+
+  std::unique_ptr<MemorySSAUpdater> MSSAU;
+  if (MSSA)
----------------
I realize this is similar to what is done in `deleteDeadLoop`, but MSSA is only passed so it can be kept up-to-date, right? Can we just pass a pointer to the updater instead (making the intended use more explicit and avoids a dynamic allocation here)
