1807 * typeck.c (structural_comptypes): Renamed from "comptypes".
1808 (comptypes): Use canonical type information to perform fast type
1809 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1810 canonical type comparison returns the same results as we would see
1811 from the current, structural check. Support COMPARE_STRUCTURAL
1812 when we need structural checks.
1813 * decl.c (typename_compare): Fix comment.
1814 (build_typename_type): TYPENAME_TYPE nodes require structural
1815 equality checks, because they resolve different based on the

1818 require structural equality checks (for now).
1819 (build_ptrmemfunc_type): Build the canonical pointer to member
1821 (compute_array_index_type): Whenever we build a new index type
1822 to represent the size of an array in a template, we need to mark
1823 this index type as requiring structural equality. This goes for
1824 arrays with value-dependent sizes with the current ABI, or all

1840 (canonical_type_parameter): New.
1841 (process_template_parm): Find the canonical type parameter.
1842 (lookup_template_class): When we have named the primary template
1843 type, set the canonical type for our template class to the primary
1844 template type. If any of the template arguments need structural
1845 equality checks, the template class needs structural equality
1847 (tsubst): When reducing the level of a template template
1848 parameter, we require structural equality tests for the resulting
1849 parameter because its template parameters have not had their types
1850 canonicalized. When reducing a template type parameter, find the
1851 canonical reduced type parameter.
1852 (any_template_arguments_need_structural_equality_p): New.
