2321 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
2323 * typeck.c (structural_comptypes): Renamed from "comptypes".
2324 (comptypes): Use canonical type information to perform fast type
2325 comparison. When VERIFY_CANONICAL_TYPES, verify that the
2326 canonical type comparison returns the same results as we would see
2327 from the current, structural check. Support COMPARE_STRUCTURAL
2328 when we need structural checks.
2329 * decl.c (typename_compare): Fix comment.
2330 (build_typename_type): TYPENAME_TYPE nodes require structural
2331 equality checks, because they resolve different based on the
2333 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
2334 require structural equality checks (for now).
2335 (build_ptrmemfunc_type): Build the canonical pointer to member
2337 (compute_array_index_type): Whenever we build a new index type
2338 to represent the size of an array in a template, we need to mark
2339 this index type as requiring structural equality. This goes for
2340 arrays with value-dependent sizes with the current ABI, or all
2342 * tree.c (cplus_array_hash): New.
2343 (struct cplus_array_info): New.

2347 types we build. Build the canonical array type for each array

2350 type, use the hash table of array types and build canonical array

2356 (canonical_type_parameter): New.
2357 (process_template_parm): Find the canonical type parameter.
2358 (lookup_template_class): When we have named the primary template
2359 type, set the canonical type for our template class to the primary
2360 template type. If any of the template arguments need structural
2361 equality checks, the template class needs structural equality
2363 (tsubst): When reducing the level of a template template
2364 parameter, we require structural equality tests for the resulting
2365 parameter because its template parameters have not had their types
2366 canonicalized. When reducing a template type parameter, find the
2367 canonical reduced type parameter.
2368 (any_template_arguments_need_structural_equality_p): New.
