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.
