 ; EPILOG: for.body.epil.preheader:
-; EPILOG:   br label %for.body.epil, !dbg [[EXIT_LOC:![0-9]+]]
+; EPILOG:   br label %for.body.epil, !dbg [[BODY_LOC:![0-9]+]]
 ; EPILOG: for.body.epil:
The test is now defining BODY_LOC three times in the EPILOG run.  Once should be enough.  (The unmodified test incorrectly defines it twice, and you've added a third.)
