	* call.c (standard_conversion): Pass flag to
	vector_types_convertible_p to disallow emission of note.
	* typeck.c (convert_for_assignment): Pass flag to
	vector_types_convertible_p to allow emission of note.
	(ptr_reasonably_similar): Pass flag to vector_types_convertible_p
	to disallow emission of note.

	PR c++/28986
	* typeck.c (build_binary_op): Call overflow_warning if
	TREE_OVERFLOW_P is true for the result and not for any of the

2007-01-06  Lee Millward  <>

	PR c++/19439
	* class.c (add_method): Don't wait until template
	instantiation time to complain about duplicate methods.

2007-01-05  Manuel Lopez-Ibanez  <>

	PR c/19978
	* semantics.c (finish_unary_op_expr): Warn only if result
	overflowed and operands did not.

2007-01-05  Ian Lance Taylor  <>

	* typeck.c (build_binary_op): Warn about comparing a non-weak
	address to NULL.

2007-01-05  Douglas Gregor  <>

	* pt.c (tsubst): Propagate the need for structural equality checks
	when reducing the level of template parameters.

2007-01-03  Kazu Hirata  <>

	* pt.c: Fix a comment typo.

2007-01-02  Ian Lance Taylor  <>

	* semantics.c (maybe_convert_cond): Optionally warn when using an
	assignment as a condition.
	* typeck.c (convert_for_assignment): Optionally warn about
	assigning the result of an assignment to a bool.

2007-01-02  Douglas Gregor  <>

	* pt.c (canonical_template_parms): Correct typo in comment.

2007-01-02  Douglas Gregor  <>

	* typeck.c (structural_comptypes): Renamed from "comptypes".
	(comptypes): Use canonical type information to perform fast type
	comparison. When VERIFY_CANONICAL_TYPES, verify that the
	canonical type comparison returns the same results as we would see
	from the current, structural check. Support COMPARE_STRUCTURAL
	when we need structural checks.
	* decl.c (typename_compare): Fix comment.
	(build_typename_type): TYPENAME_TYPE nodes require structural
	equality checks, because they resolve different based on the
	current class type.
	(make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
	require structural equality checks (for now).
	(build_ptrmemfunc_type): Build the canonical pointer to member
	function type.
	(compute_array_index_type): Whenever we build a new index type
	to represent the size of an array in a template, we need to mark
	this index type as requiring structural equality. This goes for
	arrays with value-dependent sizes with the current ABI, or all
	arrays with ABI-1.
	* tree.c (cplus_array_hash): New.
	(struct cplus_array_info): New.
	(cplus_array_compare): New.
	(cplus_array_htab): New.
	(build_cplus_array_type_1): Use a hash table to cache the array
	types we build. Build the canonical array type for each array
	(cp_build_qualified_type_real): When building a cv-qualified array
	type, use the hash table of array types and build canonical array
	types as necessary.
	(bind_template_template_parm): BOUND_TEMPLATE_TEMPLATE_PARM nodes
	use structural equality (for now).
	* cp-tree.h (COMPARE_STRUCTURAL): New.
	* pt.c (canonical_template_parms): New.
	(canonical_type_parameter): New.
	(process_template_parm): Find the canonical type parameter.
	(lookup_template_class): When we have named the primary template
	type, set the canonical type for our template class to the primary
	template type. If any of the template arguments need structural
	equality checks, the template class needs structural equality
	(tsubst): When reducing the level of a template template
	parameter, we require structural equality tests for the resulting
	parameter because its template parameters have not had their types
	canonicalized. When reducing a template type parameter, find the
	canonical reduced type parameter.
	(any_template_arguments_need_structural_equality_p): New.
