[PATCH] D46324: [BranchFolding] Allow hoisting to block with a single conditional branch.

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added inline comments.


================
Comment at: lib/CodeGen/BranchFolding.cpp:1869
     return Loc;
   if (Loc == MBB->begin())
+    return Loc;
----------------
Can you add a comment explaining what this condition checks for and why return Loc is appropriate here?
