Comment at: test/Transforms/EarlyCSE/guards.ll:270
+; Demonstrates the case we do not currently cover: branch by guarded condition.
+; We can replace the branching by cmp condition by unconditional branch.

----------------
Not in EarlyCSE (which isn't allowed to modify CFG). We can fold the condition to false at use though. That should be a separate patch.
