gcc/
* 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_schedule, model_worklist, model_insns, model_num_insns)
(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_start_update_pressure, model_update_pressure): Likewise.
(model_recompute, model_spill_cost, model_excess_group_cost): 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.
(model_record_final_pressures, model_add_successors_to_worklist)
(model_promote_predecessors, model_choose_insn): Likewise.
(model_reset_queue_indices, model_dump_pressure_summary): Likewise.
(model_start_schedule, model_finalize_pressure_group): Likewise.
(model_end_schedule): Likewise.
(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.
* sched-deps.c (init_insn_reg_pressure_info): Likewise, but don't
allocate INSN_MAX_REG_PRESSURE for SCHED_PRESSURE_MODEL.
(sched_analyze_insn): Extend INSN_REG_PRESSURE_EXCESS_COST_CHANGE
handling to SCHED_PRESSURE_MODEL.
