	* tree-loop-distribution.c (remaining_stmts,
	upstream_mem_writes): Removed static variables.
	(copy_loop_before, create_bb_after_loop,
	mark_nodes_having_upstream_mem_writes, free_rdg_components,
	rdg_build_components, rdg_build_partitions, dump_rdg_partitions): Extern.
	(generate_loops_for_partition, generate_code_for_partition): Do not
	return a bool.

	mark_nodes_having_upstream_mem_writes, has_upstream_mem_writes,
	rdg_flag_all_uses, rdg_flag_uses, rdg_flag_vertex_and_dependent,
	rdg_flag_loop_exits, rdg_flag_similar_memory_accesses,
	build_rdg_partition_for_component, rdg_build_partitions, ldist_gen): 
	Pass remaining_stmts and upstream_mem_writes as parameters.
	(rdg_component): Moved...
	(build_rdg_partition_for_component): Do not aggregate components when
	flag_streamize_loops is set.
	(gen_sequential_loops): New.
	(ldist_gen): Call gen_sequential_loops.
	
	* tree-pass.h (pass_loop_streamization): Declared.

	* omp-low.c (expand_omp_sections): Call add_bb_to_loop on created 
	basic blocks when loops structures exist.

	* builtin-types.def (BT_FN_VOID_PTR_PTR_INT): New.

	* tree-ssa-loop-ivopts.c (expr_invariant_in_region_p): New.

	* tree-parloops.c (take_address_of, eliminate_local_variables_1,
	eliminate_local_variables_stmt, eliminate_local_variables,
	separate_decls_in_loop_name, separate_decls_in_loop_stmt,
	separate_decls_in_loop, gen_parallel_loop): Make them work on a region
	of code delimited by two edges in the CFG.
	(separate_decls_in_loop_name): Renamed separate_decls_in_region_name.
	(separate_decls_in_loop_stmt): Renamed separate_decls_in_region_stmt.
	(separate_decls_in_loop): Renamed separate_decls_in_region.  Isolate

	(create_rdg_edge_for_ddr, create_rdg_edges_for_scalar): Initialise 
	RDGE_RELATION.
	(build_rdg): Don't call free_dependence_relations for the moment, as
	we attach dependence relations on each edge of the RDG.  To be fixed later.

	* tree-data-ref.h (rdg_component): ...here.
	(struct rdg_edge): New field ddr_p relation.
	(RDGE_RELATION): New.
