2010-11-22 Sebastian Pop <sebastian.pop@amd.com> PR middle-end/45297 * graphite-poly.c (new_poly_bb): Returns a poly_bb_p. Do not take the reduction bool in parameter. Clear PBB_IS_REDUCTION. Set GBB_PBB. * graphite-poly.h (new_poly_bb): Update declaration. (gbb_from_bb): Moved here... (pbb_from_bb): New. * graphite-sese-to-poly.c (var_used_in_not_loop_header_phi_node): Removed. (graphite_stmt_p): Removed. (try_generate_gimple_bb): Returns a gimple_bb_p. Do not pass in sbitmap reductions. Always build a gimple_bb_p. Do not call new_poly_bb. (build_scop_bbs_1): Do not pass in sbitmap reductions. (build_scop_bbs): Same. (gbb_from_bb): ... from here. (add_conditions_to_constraints): Moved up. (analyze_drs): New. (build_scop_drs): Call analyze_drs. Remove all the PBBs that do not contain data references. (new_pbb_from_pbb): New. (insert_out_of_ssa_copy_on_edge): Call new_pbb_from_pbb after a block is split. (rewrite_close_phi_out_of_ssa): Update call to insert_out_of_ssa_copy_on_edge. (rewrite_reductions_out_of_ssa): Now static. (rewrite_cross_bb_scalar_deps_out_of_ssa): Same. (split_pbb): New. (split_reduction_stmt): Call split_pbb. (translate_scalar_reduction_to_array): Pass in the scop, do not pass in the sbitmap reductions. (rewrite_commutative_reductions_out_of_ssa_close_phi): Same. (rewrite_commutative_reductions_out_of_ssa_loop): Same. (rewrite_commutative_reductions_out_of_ssa): Same. (build_poly_scop): Call build_scop_bbs, rewrite_commutative_reductions_out_of_ssa, rewrite_reductions_out_of_ssa, and rewrite_cross_bb_scalar_deps_out_of_ssa. Move build_scop_drs before scop_to_lst. * graphite-sese-to-poly.h (rewrite_commutative_reductions_out_of_ssa): Removed declaration. (rewrite_reductions_out_of_ssa): Same. (rewrite_cross_bb_scalar_deps_out_of_ssa): Same. (build_scop_bbs): Same. * graphite.c (graphite_transform_loops): Do not initialize reductions. Do not call build_scop_bbs, rewrite_commutative_reductions_out_of_ssa, rewrite_reductions_out_of_ssa, and rewrite_cross_bb_scalar_deps_out_of_ssa. * sese.h (struct gimple_bb): Add field pbb.
