I have narrow this failure down to the following change:
2003-01-28 Vladimir Makarov <email@example.com>
* haifa-sched.c (schedule_insn): Return necessary cycle advance
after issuing the insn.
(rank_for_schedule): Make a insn with /S the highest priority
(move_insn): Ignore schedule groups. Clear SCHED_GROUP_P.
(choose_ready): Check SCHED_GROUP_P.
(schedule_block): Advance cycle after issuing insn if it is
necessary. Don't reorder insns if there is an insn with /S.
(set_priorities): Ignore schedule groups.
* sched-deps.c (remove_dependence, group_leader): Remove the
(add_dependence): Ignore schedule groups.
(set_sched_group_p): Don't make copy of dependencies from previous
insn of the schedule group. Add anti-dependency to the previous
insn of the schedule group.
(compute_forward_dependences): Ignore schedule groups.
* sched-ebb.c (init_ready_list): Ignore schedule groups.
* sched-rgn.c (init_ready_list): Ditto.
