================
Comment at: lib/Transforms/Utils/LCSSA.cpp:217
 
-    // Keep track of PHI nodes that we want to remove because they did not have
-    // any uses rewritten. If the new PHI is used, store it so that we can
-    // try to propagate dbg.value intrinsics to it.
+    // Keep track of PHI nodes that we createe, so that we can remove them again
+    // if they did not have any uses rewritten.
