[PATCH] D71569: [LoopFusion] Ensure that both loops are guarded or neither are guarded.

[Whitney Tsang via Phabricator via llvm-commits]

Whitney added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/LoopFuse.cpp:1070
+    if (!((FC0.GuardBranch && FC1.GuardBranch) ||
+          (!FC0.GuardBranch && !FC1.GuardBranch)))
+      return false;
----------------
haveIdenticalGuards() is not called with both candidates unguarded, so (!FC0.GuardBranch && !FC1.GuardBranch) is impossible.
