tree-vectorizer.h (struct _stmt_vec_info): Rename a field: base to base_address.
2005-02-13 Ira Rosen <irar@il.ibm.com>
* tree-vectorizer.h (struct _stmt_vec_info): Rename a field: base
to base_address.
* tree-vectorizer.c (new_stmt_vec_info): Rename the above field of
stmt_vec_info.
(vect_get_base_and_offset): Always return an address.
(vect_create_addr_base_for_vector_ref): Remove treatment for
different data reference types.
(vect_compute_data_ref_alignment): Rename base to base_address in
stmt_vec_info. Get the object in order to force its alignment.
(vect_get_memtag_and_dr): Rename base to base_address in
stmt_vec_info. Extract the object for memtag analysis.
