Memoize memory strides per loop.
2010-01-07 Sebastian Pop <sebastian.pop@amd.com>
* graphite-interchange.c (memory_stride_in_loop): Renamed
pdr_stride_in_loop.
(memory_strides_in_loop): Renamed memory_strides_in_loop_1.
(memory_strides_in_loop): Memoize the memory strides per loop.
(lst_interchange_profitable_p): Do not initialize to zero the memory
strides.
* graphite-poly.h (struct lst): Add a field memory_strides.
(LST_LOOP_MEMORY_STRIDES): New.
(new_lst_loop): Initialize LST_LOOP_MEMORY_STRIDES to -1.
(free_lst): Clear LST_LOOP_MEMORY_STRIDES.
