Zdenek Dvorak 3cb960c703 tree-scalar-evolution.c (resolve_mixers): Exported.
* tree-scalar-evolution.c (resolve_mixers): Exported.
	* tree-scalar-evolution.h (resolve_mixers): Declare.
	* tree-data-ref.c (object_analysis, ptr_decl_may_alias_p,
	ptr_ptr_may_alias_p, may_alias_p, record_ptr_differ_p,
	record_record_differ_p, record_array_differ_p, array_ptr_differ_p,
	base_object_differ_p, base_addr_differ_p, analyze_array_indexes,
	init_array_ref, init_pointer_ref, analyze_indirect_ref,
	strip_conversion, analyze_offset_expr, address_analysis,
	object_analysis, analyze_offset): Removed.
	(dr_analyze_innermost, dr_analyze_indices, dr_analyze_alias,
	split_constant_offset, canonicalize_base_object_address,
	object_address_invariant_in_loop_p, disjoint_objects_p,
	dr_may_alias_p, dr_address_invariant_p): New functions.
	(create_data_ref): Use dr_analyze_innermost, dr_analyze_indices
	and dr_analyze_alias.
	(initialize_data_dependence_relation): Use dr_may_alias_p
	and object_address_invariant_in_loop_p.
	(compute_self_dependence): Handle the case when DDR_ARE_DEPENDENT (ddr)
	is chrec_dont_know.
	(find_data_references_in_stmt): Restrict the analysis of data references
	to the given loop nest.
	(find_data_references_in_loop): Made static.  Pass loop nest to
	find_data_references_in_stmt.
	(compute_data_dependences_for_loop): Use DR_VOPS.
	(free_data_ref): Free DR_VOPS.
	* tree-data-ref.h (struct first_location_in_loop): Replaced by ...
	(struct innermost_loop_behavior): ... new.
	(struct base_object_info): Replaced by ...
	(struct indices): ... new.
	(struct dr_alias): New.
	(enum data_ref_type): Removed.
	(struct data_reference): Consist of struct innermost_loop_behavior,
	struct indices and struct dr_alias.
	(DR_SET_ACCESS_FNS, DR_FREE_ACCESS_FNS): Removed.
	(DR_MEMTAG): Renamed to ...
	(DR_SYMBOL_TAG): ... this.
	(find_data_references_in_loop): Declaration removed.
	* tree-vect-analyze.c (vect_compute_data_ref_alignment): Use DR_INIT
	instead of DR_OFFSET_MISALIGNMENT.  DR_ALIGNED_TO is never NULL.
	(vect_analyze_data_refs): Use DR_SYMBOL_TAG instead of DR_MEMTAG.
	* tree-vect-transform.c (vect_create_data_ref_ptr): Ditto.

	* gcc.dg/vect/no-section-anchors-vect-69.c: Fix outcome.
	* gcc.dg/tree-ssa/loop-30.c: New test.
