2009-10-22 Sebastian Pop <sebastian.pop@amd.com>
* graphite-poly.c (new_scop): Initialize SCOP_ORIGINAL_SCHEDULE,
SCOP_TRANSFORMED_SCHEDULE, and SCOP_SAVED_SCHEDULE.
(free_scop): Call free_lst on SCOP_ORIGINAL_SCHEDULE,
SCOP_TRANSFORMED_SCHEDULE, and SCOP_SAVED_SCHEDULE.
* graphite-poly.h (free_lst): New.
(store_lst_schedule): Free SCOP_SAVED_SCHEDULE.
(restore_lst_schedule): Free SCOP_TRANSFORMED_SCHEDULE.
