* tree-chrec.c (eq_evolutions_p): New.
* tree-chrec.h (eq_evolutions_p): Declared.
* tree-data-ref.c: Fix formatting.
(datadep_stats, dependence_stats): New.
(gcd): Moved...
(print_direction_vector): New.
(dump_data_dependence_relation): Use print_direction_vector.
(object_analysis, create_data_ref): Handle COMPONENT_REF.
(compute_subscript_distance): Static.
(initialize_data_dependence_relation): Static.  Get the number
of loops surrounding the references from the callers, and initialize
DDR_SIZE_VECT to nb_loops.  Use both base_addr_differ_p and
base_object_differ_p analyzers.
(analyze_ziv_subscript, analyze_siv_subscript_cst_affine,
compute_overlap_steps_for_affine_1_2,
analyze_subscript_affine_affine): Count the classified dependences.
Print a message when a test failed.
(can_use_analyze_subscript_affine_affine): New.
(analyze_siv_subscript): Compute the data dependences on symbolic
scevs that verify can_use_analyze_subscript_affine_affine.
(chrec_steps_divide_constant_p): Returns true, false, or unknown.
(analyze_miv_subscript): Update use of chrec_steps_divide_constant_p.
Handle symbolic scevs.
(analyze_overlapping_iterations): Let symbolic affine scevs to be
analyzed.
(subscript_dependence_tester): Moved...
(build_classic_dist_vector, build_classic_dir_vector): Don't use
lambda_vector_clear on newly allocated vectors.  Get nb_loops from
DDR_SIZE_VECT instead of getting it in parameter.
(subscript_dependence_tester): ... here.  Take as a parameter
loop_nest_depth.  Call build_classic_dist_vector and
build_classic_dir_vector.
(compute_affine_dependence): Update subscript_dependence_tester
parameters.  Update datadep_stats counters.  Call
compute_subscript_distance.
(compute_self_dependence): Save the dist and dir vectors.  Call
compute_subscript_distance.
(ddr_p, DEF_VEC_P(ddr_p), DEF_VEC_ALLOC_P(ddr_p,heap)): Moved...
(compute_all_dependences): Reorder parameters as they were before
conversion to VEC.  Pass nb_loops and loop_nest_depth.  Don't call
compute_subscript_distance.  Update the use of
compute_affine_dependence and initialize_data_dependence_relation.
(find_data_references_in_loop): Handle COMPONENT_REF.
(compute_data_dependences_for_loop): Initialize dependence_stats.
Don't call build_classic_dist_vector and build_classic_dir_vector.
Update the parameters of initialize_data_dependence_relation and
compute_all_dependences.  Print the statistics from datadep_stats.
(analyze_all_data_dependences): Static.  Not used until the pass for
checking the data dependences is contributed.
* tree-data-ref.h (ddr_p, DEF_VEC_P(ddr_p),
DEF_VEC_ALLOC_P(ddr_p,heap)): ... here.
(initialize_data_dependence_relation, compute_affine_dependence,
analyze_all_data_dependences, compute_subscript_distance): Removed.
(print_direction_vector): New.
* lambda.h (gcd): ... here.
(lambda_vector_gcd): Moved here from gcd_vector.
* lambda-code.c (gcd, gcd_vector): Removed.
(lambda_compute_target_space): Use lambda_vector_gcd.  Fix formatting.
* Makefile.in (tree-vect-patterns.o): Depends on TREE_DATA_REF_H.
