1707 * typeck.c (build_binary_op): Call overflow_warning if
1708 TREE_OVERFLOW_P is true for the result and not for any of the
1711 2007-01-06 Lee Millward <lee.millward@codesourcery.com>
1714 * class.c (add_method): Don't wait until template
1715 instantiation time to complain about duplicate methods.

1725 * typeck.c (build_binary_op): Warn about comparing a non-weak
1728 2007-01-05 Douglas Gregor <doug.gregor@gmail.com>
1730 * pt.c (tsubst): Propagate the need for structural equality checks

1742 assigning the result of an assignment to a bool.

1748 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1750 * typeck.c (structural_comptypes): Renamed from "comptypes".
1751 (comptypes): Use canonical type information to perform fast type
1752 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1753 canonical type comparison returns the same results as we would see
1754 from the current, structural check. Support COMPARE_STRUCTURAL
1755 when we need structural checks.
1756 * decl.c (typename_compare): Fix comment.
1757 (build_typename_type): TYPENAME_TYPE nodes require structural
1758 equality checks, because they resolve different based on the
1760 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
1761 require structural equality checks (for now).
1762 (build_ptrmemfunc_type): Build the canonical pointer to member
1764 (compute_array_index_type): Whenever we build a new index type
1765 to represent the size of an array in a template, we need to mark
1766 this index type as requiring structural equality. This goes for
1767 arrays with value-dependent sizes with the current ABI, or all
1769 * tree.c (cplus_array_hash): New.

1774 types we build. Build the canonical array type for each array

1777 type, use the hash table of array types and build canonical array

1783 (canonical_type_parameter): New.
1784 (process_template_parm): Find the canonical type parameter.
1785 (lookup_template_class): When we have named the primary template
1786 type, set the canonical type for our template class to the primary
1787 template type. If any of the template arguments need structural
1788 equality checks, the template class needs structural equality
1790 (tsubst): When reducing the level of a template template
1791 parameter, we require structural equality tests for the resulting
1792 parameter because its template parameters have not had their types
1793 canonicalized. When reducing a template type parameter, find the
1794 canonical reduced type parameter.
1795 (any_template_arguments_need_structural_equality_p): New.
