------- Comment #3 from lifeng at gcc dot gnu dot org 2009-09-20 10:47 ------- We should check if 2 data reference are with the same base object before checking dependency. This bug has been fix. Now has committed to Graphite branch.
http://gcc.gnu.org/viewcvs?view=revision&revision=151801 * graphite-dependences.c (poly_drs_may_alias_p): Adjust definition. (pddr_original_scattering): Make sure 2 pdr2 in the same base object set. (graphite_carried_dependence_level_k): Ditto. * graphite-poly.c (new_poly_dr): Add init of PDR_BASE_OBJECT_SET. * graphite-poly.h (struct poly_dr): Add member dr_base_object_set. (new_poly_dr): Adjust declaration. * graphite-sese-to-poly.c (free_data_refs_aux): New. (free_gimple_bb): Added free_data_refs_aux. (build_poly_dr): Add dr_base_object_set. (partition_drs_to_sets): New. (dr_same_base_object_p): New. (build_alias_set_for_drs): New. (build_base_object_set_for_drs): New. (build_scop_drs): Add build_base_obj_set_for_drs. * graphite-sese-to-poly.h: Added #define for alias set number index and base object set index. * libgomp/testsuite/libgomp.graphite/force-parallel-6.c: Refine tests. * libgomp/testsuite/libgomp.graphite/pr4118.c: New. -- lifeng at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lifeng at gcc dot gnu dot | |org Status|ASSIGNED |RESOLVED Resolution| |FIXED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41118
