31228 * c-common.c (c_common_nodes_and_builtins): Since variants of
31229 void_type_node get built before it is given a name, we need to
31230 give those variants the name, too.
31231 (complete_array_type): We need to work with the canonical main
31232 type of the array, from which we will build the qualified version.

31236 * stor-layout.c (layout_type): When we don't know the
31237 alignment of a type for which we're building an array, we end up
31238 guessing wrong, so make the type require structural equality.
31239 * tree.c (make_node_stat): When we build a new type, it is its
31240 own canonical type.
31241 (build_type_attribute_qual_variant): When building an attribute
31242 variant, its canonical type is the non-attribute variant. However,
31243 if the attributes are target-dependent and they differ, we need to
31244 use structural equality checks for this type.
31245 (build_qualified_type): A qualified type is not equivalent to its
31246 unqualified variant; set the canonical type appropriately.
31247 (build_distinct_type_copy): When building a distinct type from
31248 another type, the new type is its own canonical type.
31249 (build_variant_type_copy): When building a new type variant, we
31250 assume that it is equivalent to the original type.
31251 (build_pointer_type_for_mode): When building a pointer type, also
31252 build a canonical type pointer.
31253 (build_reference_type_for_mode): When building a reference type,
31254 also build a canonical type reference.
31255 (build_index_type): When we can't hash an index type (e.g.,
31256 because its maximum value is negative), the index type requires
31257 structural equality tests.
31258 (build_array_type): Build the canonical form of an array type.
31259 (build_function_type): Function types require structural equality,
31260 because they contain default arguments, attributes, etc.
31261 (build_method_type_directly): Ditto for method types.
31262 (build_offset_type): Build the canonical offset type.
