2005-03-31 Mostafa Hagog <mustafa@il.ibm.com>
* cfg.c (clear_bb_flags): Don't clear BB_DISABLE_SCHEDULE.
* modulo-sched.c (undo_replace_buff_elem): New structure.
(kernel_number_of_cycles, ps_unschedule_node,
undo_generate_reg_moves,free_undo_replace_buff,
undo_permute_partial_schedule, loop_single_full_bb_p,
SIMPLE_SMS_LOOP_P, loop_canon_p, canon_loop,
build_loops_structure, get_sched_window): New.
(generate_reg_moves): Return undo_replace_buff_elem and other
fixes.
(generate_prolog_epilog): Remove old loop versioning.
(sms_schedule): Use loop information and loop_version.
(sms_schedule_by_order): Split part of it to get_sched_window.
* passes.c (rest_of_handle_sms): call cfg_layout_initialize
cfg_layout_finalize and free_dominance_info before/after SMS.
