graphite-interchange.c (pbb_interchange_profitable_p): Adjust the strides by multiplying by PDR_NB_REFS.
2009-08-28 Sebastian Pop <sebastian.pop@amd.com>
* graphite-interchange.c (pbb_interchange_profitable_p): Adjust
the strides by multiplying by PDR_NB_REFS.
* graphite-poly.c (can_collapse_pdr): New.
(pdr_find_duplicate): New.
(new_poly_dr): Call pdr_find_duplicate. Collapse duplicate PDRs.
Initialize PDR_NB_REFS.
* graphite-poly.h (struct poly_dr): Add field nb_refs.
(PDR_NB_REFS): New.
(new_poly_dr): Number of subscripts is a graphite_dim_t.
