28164 * c-common.c (c_common_nodes_and_builtins): Since variants of
28165 void_type_node get built before it is given a name, we need to
28166 give those variants the name, too.
28167 (complete_array_type): We need to work with the canonical main
28168 type of the array, from which we will build the qualified version.

28172 * stor-layout.c (layout_type): When we don't know the
28173 alignment of a type for which we're building an array, we end up
28174 guessing wrong, so make the type require structural equality.
28175 * tree.c (make_node_stat): When we build a new type, it is its
28176 own canonical type.
28177 (build_type_attribute_qual_variant): When building an attribute
28178 variant, its canonical type is the non-attribute variant. However,
28179 if the attributes are target-dependent and they differ, we need to
28180 use structural equality checks for this type.
28181 (build_qualified_type): A qualified type is not equivalent to its
28182 unqualified variant; set the canonical type appropriately.
28183 (build_distinct_type_copy): When building a distinct type from
28184 another type, the new type is its own canonical type.
28185 (build_variant_type_copy): When building a new type variant, we
28186 assume that it is equivalent to the original type.
28187 (build_pointer_type_for_mode): When building a pointer type, also
28188 build a canonical type pointer.
28189 (build_reference_type_for_mode): When building a reference type,
28190 also build a canonical type reference.
28191 (build_index_type): When we can't hash an index type (e.g.,
28192 because its maximum value is negative), the index type requires
28193 structural equality tests.
28194 (build_array_type): Build the canonical form of an array type.
28195 (build_function_type): Function types require structural equality,
28196 because they contain default arguments, attributes, etc.
28197 (build_method_type_directly): Ditto for method types.
28198 (build_offset_type): Build the canonical offset type.
28199 (build_complex_type): Build the canonical vector type.
