18212 * c-common.c (c_common_nodes_and_builtins): Since variants of
18213 void_type_node get built before it is given a name, we need to
18214 give those variants the name, too.
18215 (complete_array_type): We need to work with the canonical main
18216 type of the array, from which we will build the qualified version.

18218 * print-tree.c (print_node): Display canonical type information
18220 * stor-layout.c (layout_type): When we don't know the
18221 alignment of a type for which we're building an array, we end up
18222 guessing wrong, so make the type require structural equality.
18223 * tree.c (make_node_stat): When we build a new type, it is its
18224 own canonical type.
18225 (build_type_attribute_qual_variant): When building an attribute
18226 variant, its canonical type is the non-attribute variant. However,
18227 if the attributes are target-dependent and they differ, we need to
18228 use structural equality checks for this type.
18229 (build_qualified_type): A qualified type is not equivalent to its
18230 unqualified variant; set the canonical type appropriately.
18231 (build_distinct_type_copy): When building a distinct type from
18232 another type, the new type is its own canonical type.
18233 (build_variant_type_copy): When building a new type variant, we
18234 assume that it is equivalent to the original type.
18235 (build_pointer_type_for_mode): When building a pointer type, also
18236 build a canonical type pointer.
18237 (build_reference_type_for_mode): When building a reference type,
18238 also build a canonical type reference.
18239 (build_index_type): When we can't hash an index type (e.g.,
18240 because its maximum value is negative), the index type requires
18241 structural equality tests.
18242 (build_array_type): Build the canonical form of an array type.
18243 (build_function_type): Function types require structural equality,
18244 because they contain default arguments, attributes, etc.
18245 (build_method_type_directly): Ditto for method types.
