[PATCH] D95806: [LoopUnrollAndJam] Check if the loops have an Exit Block

[Whitney Tsang via Phabricator via llvm-commits]

Whitney added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/LoopUnrollAndJam.cpp:818
 
     if (!L->isRotatedForm())
       return false;
----------------
```
   bool isRotatedForm() const {
     assert(!isInvalid() && "Loop not in a valid state!");
     BasicBlock *Latch = getLoopLatch();
     return Latch && isLoopExiting(Latch);
   }
```
So shouldn't one of latch successor be an exit block?
