* common.opt (freschedule-modulo-scheduled-loops): New flag.
* final.c (final_scan_insn): Handle NOTE_DISABLE_SCHED_OF_BLOCK.
* modulo-sched.c (sms_schedule): Emit a note to disable scheduling
when -freschedule-modulo-scheduled-loops flag is not specified.
(sms_schedule_by_order, ps_insn_advance_column, add_node_to_ps,
add_node_to_ps, ps_has_conflicts, ps_add_node_check_conflicts):
More accurate placing of insn in row of partial schedule.
(ps_insn_find_column): New function.
* rtl.h (NOTE_DISABLE_SCHED_OF_BLOCK): New note.
* sched-rgn.c (sched_is_disabled_for_current_region_p): New.
(schedule_region): Use sched_is_disabled_for_current_region_p.
* docs/invoke.texi: Document -freschedule-modulo-scheduled-loops.
