[PATCH] D66529: [LOOPGUARD] Disable loop with multiple loop exiting blocks.

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added inline comments.


================
Comment at: llvm/lib/Analysis/LoopInfo.cpp:372-375
+  SmallVector<BasicBlock *, 2> ExitBlocks;
+  getUniqueExitBlocks(ExitBlocks);
+  if (ExitBlocks.size() != 1)
     return nullptr;
----------------
There actually is a `LoopBase::getUniqueExitBlock()` with this code inside. Could you use that one?
