------- Comment #2 from steven at gcc dot gnu dot org  2007-02-21 22:09 -------
On the trunk, *and* on the dataflow branch, we crossjump the code starting with
"if (i != 1)" on the first cleanup_cfg iteration when it's called from
rest_of_handle_stack_adjustments.  Trunk then goes on to crossjump the other
blocks, but the df-branch stops because there is a set to the CC-reg in the
way. That set has a REG_UNUSED flag on it.

What probably happens, is that flow on the trunk does some dce in the liveness
update, and the df-branch does not.
