[Ira Rosen <IRAR at il dot ibm dot com>]

Hi,

This patch adds multidimensional arrays support to the vectorizer, along
with relevant new test-cases.

Thanks,
Ira

Changelog entry:

2004-08-12  Ira Rosen <irar@il.ibm.com>

        * tree-vectorizer.h (stmt_vec_info): Add vect_dr_base field.
        (STMT_VINFO_VECT_DR_BASE): Declare.
        (VECT_SMODULO): Declare.

        * tree-vectorizer.c (vect_compute_array_alignment): New function.
        (vect_compute_data_ref_alignment): Call
vect_compute_array_alignment.
        (vect_analyze_data_ref_access): Check array indices. Remove one
dimensional arrays restriction.
        (vect_analyze_data_refs): Store vect_dr_base.
        (vect_create_data_ref): Create multidimensional array reference.
        (vect_create_index_for_array_ref): Return init value. Remove check
for one dimensional arrays.
         Change init value calculation.
        (new_stmt_vec_info): Initialize vect_dr_base field.
        (vect_update_initial_conditions_of_duplic): Remove call to
instantiate_parameters.
        (vect_is_simple_iv_evolution): Call initial_condition_in_loop_num.

        * tree-chrec.h (initial_condition_in_loop_num): Declare.

        * tree-chrec.c (initial_condition_in_loop_num): New function.
        (chrec_component_in_loop_num): New function.
        (evolution_part_in_loop_num): Call chrec_component_in_loop_num.

        * tree-data-ref.c (analyze_array_indexes): Change parameter
(access_fns) to be pointer to varray_type.
