2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>

	* c-common.c (c_common_nodes_and_builtins): Since variants of
	void_type_node get built before it is given a name, we need to
	give those variants the name, too.
	(complete_array_type): We need to work with the canonical main
	type of the array, from which we will build the qualified version.
	* params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
	* print-tree.c (print_node): Display canonical type information
	for each type.
	* stor-layout.c (layout_type): When we don't know the
	alignment of a type for which we're building an array, we end up
	guessing wrong, so make the type require structural equality.
	* tree.c (make_node_stat): When we build a new type, it is its
	own canonical type.
	(build_type_attribute_qual_variant): When building an attribute
	variant, its canonical type is the non-attribute variant. However,
	if the attributes are target-dependent and they differ, we need to
	use structural equality checks for this type.
	(build_qualified_type): A qualified type is not equivalent to its
	unqualified variant; set the canonical type appropriately.
	(build_distinct_type_copy): When building a distinct type from
	another type, the new type is its own canonical type.
	(build_variant_type_copy): When building a new type variant, we
	assume that it is equivalent to the original type.
	(build_pointer_type_for_mode): When building a pointer type, also
	build a canonical type pointer.
	(build_reference_type_for_mode): When building a reference type,
	also build a canonical type reference.
	(build_index_type): When we can't hash an index type (e.g.,
	because its maximum value is negative), the index type requires
	structural equality tests.
	(build_array_type): Build the canonical form of an array type.
	(build_function_type): Function types require structural equality,
	because they contain default arguments, attributes, etc.
	(build_method_type_directly): Ditto for method types.
	(build_offset_type): Build the canonical offset type.
	(build_complex_type): Build the canonical vector type.
	(make_vector_type): Build the canonical vector type.

	(TYPE_STRUCTURAL_EQUALITY_P): New.
	(SET_TYPE_STRUCTURAL_EQUALITY): New.
