------- Comment #13 from steven at gcc dot gnu dot org 2007-02-03 16:20 -------
Haven't seen any reports of wrong-code coming out of register renaming in a
while. Register renaming is enabled if loop unrolling / peeling is enabled. So
the test coverage of this pass is much better than it used to be. I think that
the wrong-code issue for this bug is fixed.
