2360 * typeck.c (structural_comptypes): Renamed from "comptypes".
2361 (comptypes): Use canonical type information to perform fast type
2362 comparison. When VERIFY_CANONICAL_TYPES, verify that the
2363 canonical type comparison returns the same results as we would see
2364 from the current, structural check. Support COMPARE_STRUCTURAL
2365 when we need structural checks.
2366 * decl.c (typename_compare): Fix comment.
2367 (build_typename_type): TYPENAME_TYPE nodes require structural
2368 equality checks, because they resolve different based on the

2371 require structural equality checks (for now).
2372 (build_ptrmemfunc_type): Build the canonical pointer to member
2374 (compute_array_index_type): Whenever we build a new index type
2375 to represent the size of an array in a template, we need to mark
2376 this index type as requiring structural equality. This goes for
2377 arrays with value-dependent sizes with the current ABI, or all

2387 type, use the hash table of array types and build canonical array

2393 (canonical_type_parameter): New.
2394 (process_template_parm): Find the canonical type parameter.
2395 (lookup_template_class): When we have named the primary template
2396 type, set the canonical type for our template class to the primary
2397 template type. If any of the template arguments need structural
2398 equality checks, the template class needs structural equality
2400 (tsubst): When reducing the level of a template template
2401 parameter, we require structural equality tests for the resulting
2402 parameter because its template parameters have not had their types
2403 canonicalized. When reducing a template type parameter, find the
2404 canonical reduced type parameter.
2405 (any_template_arguments_need_structural_equality_p): New.
