toplev.c (flag_schedule_reverse_before_reload): Delete variable.
* toplev.c (flag_schedule_reverse_before_reload): Delete variable.
(flag_schedule_reverse_after_reload): Likewise.
(f_options): Remove reverse scheduling support.
* flags.h (flag_schedule_reverse_before_reload): Delete declaration.
(flag_schedule_reverse_after_reload): Likewise.
* haifa-sched.c (rank_for_schedule): Remove support for reverse
scheduling.
Trivial cleanup.
