------- Comment #16 from hubicka at gcc dot gnu dot org 2009-02-08 12:40 -------
Since the splitting peep2 don't seem to be win in general (it wins only when
copy propagation takes place afterwards) and we don't seem to understand what
really makes the testcase faster I am unassigning myself until we get better
idea what is going on here.
