[PATCH] D63885: [LOOPINFO] Introduce the loop guard API.

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added inline comments.


================
Comment at: llvm/lib/Analysis/LoopInfo.cpp:418-419
+      // loops.
+      if (!Succ->getUniqueSuccessor())
+        return true;
+
----------------
With this added, we don't need a DominatorTree anymore. Any guard will directly branch into the header (or a series of unconditional branches such as the preheader).
