Add PDR->nb_subscripts.
2009-08-11 Sebastian Pop <sebastian.pop@amd.com>
* graphite-dependences.c (dependence_polyhedron_1): Replace
pdr_nb_subscripts with PDR_NB_SUBSCRIPTS.
(graphite_legal_transform_dr): Same.
(graphite_carried_dependence_level_k): Same.
* graphite-poly.c (new_poly_dr): Add a parameter nb_subscripts.
Initialize PDR_NB_SUBSCRIPTS.
(print_pdr_access_layout): Replace pdr_nb_subscripts with
PDR_NB_SUBSCRIPTS.
* graphite-poly.h (struct poly_dr): Add nb_subscripts field.
(PDR_NB_SUBSCRIPTS): New.
(pdr_nb_subscripts): Removed.
(pdr_dim): Simplified.
* graphite-sese-to-poly.c (build_poly_dr): Replace pdr_nb_subscripts
with PDR_NB_SUBSCRIPTS.
