	* sched-int.h (_haifa_insn_data): Move priority_status.
	Add model_index.
	(INSN_MODEL_INDEX): New macro.
	* haifa-sched.c (insn_delay): New function.
	(sched_regno_pressure_class): Update commentary.
	(mark_regno_birth_or_death): Pass the liveness bitmap and
	pressure array as arguments, instead of using curr_reg_live and
	curr_reg_pressure.  Only update the pressure if the bit in the
	liveness set has changed.
	(initiate_reg_pressure_info): Always trust the live-in set for
	SCHED_PRESSURE_MODEL.
	(initiate_bb_reg_pressure_info): Update call to
	mark_regno_birth_or_death.
	(dep_list_size): Take the list as argument.
	(calculate_reg_deaths): New function, extracted from...
	(setup_insn_reg_pressure_info): ...here.
	(MODEL_BAR): New macro.
	(model_pressure_data, model_insn_info, model_pressure_limit)
	(model_pressure_group): New structures.

	(model_curr_point, model_before_pressure, model_next_priority):
	New variables.
	(MODEL_PRESSURE_DATA, MODEL_MAX_PRESSURE, MODEL_REF_PRESSURE)
	(MODEL_INSN_INFO, MODEL_INSN): New macros.
	(model_index, model_update_limit_points_in_group): New functions.
	(model_update_limit_points, model_last_use_except): Likewise.

	(model_excess_cost, model_dump_pressure_points): Likewise.
	(model_set_excess_costs): Likewise.
	(rank_for_schedule): Extend SCHED_PRIORITY_WEIGHTED ordering to
	SCHED_PRIORITY_MODEL.  Use insn_delay.  Use the order in the model
	schedule as an alternative tie-breaker.  Update the call to
	dep_list_size.
	(ready_sort): Call model_set_excess_costs.
	(update_register_pressure): Update call to mark_regno_birth_or_death.
	Rely on that function to check liveness rather than doing it here.
	(model_classify_pressure, model_order_p, model_add_to_worklist_at)
	(model_remove_from_worklist, model_add_to_worklist, model_promote_insn)
	(model_add_to_schedule, model_analyze_insns, model_init_pressure_group)
	(model_record_pressure, model_record_pressures): New functions.

	(schedule_insn): Say when we're scheduling the next instruction
	in the model schedule.
	(schedule_insn): Handle SCHED_PRESSURE_MODEL.
	(queue_to_ready): Do not add instructions that are
	MAX_SCHED_READY_INSNS beyond the current point of the model schedule.
	Always allow the next instruction in the model schedule to be added.
	(debug_ready_list): Print the INSN_REG_PRESSURE_EXCESS_COST_CHANGE
	and delay for SCHED_PRESSURE_MODEL too.
	(prune_ready_list): Extend SCHED_PRIORITY_WEIGHTED handling to
	SCHED_PRIORITY_MODEL, but also take the DFA into account.
	(schedule_block): Call model_start_schedule and model_end_schedule.
	Extend SCHED_PRIORITY_WEIGHTED stall handling to SCHED_PRIORITY_MODEL.
	(sched_init): Extend INSN_REG_PRESSURE_EXCESS_COST_CHANGE handling
	to SCHED_PRESSURE_MODEL, but don't allocate saved_reg_live or
	region_ref_regs.
	(sched_finish): Update accordingly.
	(fix_tick_ready): Extend INSN_REG_PRESSURE_EXCESS_COST_CHANGE handling
	to SCHED_PRESSURE_MODEL.
	(add_jump_dependencies): Update call to dep_list_size.
	(haifa_finish_h_i_d): Fix leak of max_reg_pressure.
	(haifa_init_insn): Extend INSN_REG_PRESSURE_EXCESS_COST_CHANGE handling
	to SCHED_PRESSURE_MODEL.

	handling to SCHED_PRESSURE_MODEL.
