+ * 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,

+ (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.
