 I have narrow this failure down to the following change:
 
 2003-01-28  Vladimir Makarov  <vmakarov@redhat.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
         insn.
         (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
         functions.
         (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.
         (can_schedule_ready_p): Ditto.
