18198 void_type_node get built before it is given a name, we need to
18199 give those variants the name, too.
18200 (complete_array_type): We need to work with the canonical main
18201 type of the array, from which we will build the qualified version.
18202 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
18203 * print-tree.c (print_node): Display canonical type information
18205 * stor-layout.c (layout_type): When we don't know the
18206 alignment of a type for which we're building an array, we end up
18207 guessing wrong, so make the type require structural equality.
18208 * tree.c (make_node_stat): When we build a new type, it is its
18209 own canonical type.
18210 (build_type_attribute_qual_variant): When building an attribute
18211 variant, its canonical type is the non-attribute variant. However,
18212 if the attributes are target-dependent and they differ, we need to
18213 use structural equality checks for this type.
18214 (build_qualified_type): A qualified type is not equivalent to its
18215 unqualified variant; set the canonical type appropriately.
18216 (build_distinct_type_copy): When building a distinct type from
18217 another type, the new type is its own canonical type.
18218 (build_variant_type_copy): When building a new type variant, we
18219 assume that it is equivalent to the original type.
18220 (build_pointer_type_for_mode): When building a pointer type, also
18221 build a canonical type pointer.
18222 (build_reference_type_for_mode): When building a reference type,
18223 also build a canonical type reference.
18224 (build_index_type): When we can't hash an index type (e.g.,
18225 because its maximum value is negative), the index type requires
18226 structural equality tests.
18227 (build_array_type): Build the canonical form of an array type.
18228 (build_function_type): Function types require structural equality,
18229 because they contain default arguments, attributes, etc.
18230 (build_method_type_directly): Ditto for method types.
18231 (build_offset_type): Build the canonical offset type.
