1755 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1757 * typeck.c (structural_comptypes): Renamed from "comptypes".
1758 (comptypes): Use canonical type information to perform fast type
1759 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1760 canonical type comparison returns the same results as we would see
1761 from the current, structural check. Support COMPARE_STRUCTURAL
1762 when we need structural checks.
1763 * decl.c (typename_compare): Fix comment.
1764 (build_typename_type): TYPENAME_TYPE nodes require structural
1765 equality checks, because they resolve different based on the
1767 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
1768 require structural equality checks (for now).
1769 (build_ptrmemfunc_type): Build the canonical pointer to member
1771 (compute_array_index_type): Whenever we build a new index type
1772 to represent the size of an array in a template, we need to mark
1773 this index type as requiring structural equality. This goes for
1774 arrays with value-dependent sizes with the current ABI, or all
1776 * tree.c (cplus_array_hash): New.

1781 types we build. Build the canonical array type for each array
1783 (cp_build_qualified_type_real): When building a cv-qualified array
1784 type, use the hash table of array types and build canonical array

1790 (canonical_type_parameter): New.
1791 (process_template_parm): Find the canonical type parameter.
1792 (lookup_template_class): When we have named the primary template
1793 type, set the canonical type for our template class to the primary
1794 template type. If any of the template arguments need structural
1795 equality checks, the template class needs structural equality
1797 (tsubst): When reducing the level of a template template
1798 parameter, we require structural equality tests for the resulting
1799 parameter because its template parameters have not had their types
1800 canonicalized. When reducing a template type parameter, find the
1801 canonical reduced type parameter.
1802 (any_template_arguments_need_structural_equality_p): New.
