14383 * c-common.c (c_common_nodes_and_builtins): Since variants of
14384 void_type_node get built before it is given a name, we need to
14385 give those variants the name, too.
14386 (complete_array_type): We need to work with the canonical main
14387 type of the array, from which we will build the qualified version.

14391 * stor-layout.c (layout_type): When we don't know the
14392 alignment of a type for which we're building an array, we end up
14393 guessing wrong, so make the type require structural equality.
14394 * tree.c (make_node_stat): When we build a new type, it is its
14395 own canonical type.
14396 (build_type_attribute_qual_variant): When building an attribute
14397 variant, its canonical type is the non-attribute variant. However,
14398 if the attributes are target-dependent and they differ, we need to
14399 use structural equality checks for this type.
14400 (build_qualified_type): A qualified type is not equivalent to its
14401 unqualified variant; set the canonical type appropriately.
14402 (build_distinct_type_copy): When building a distinct type from
14403 another type, the new type is its own canonical type.
14404 (build_variant_type_copy): When building a new type variant, we
14405 assume that it is equivalent to the original type.
14406 (build_pointer_type_for_mode): When building a pointer type, also
14407 build a canonical type pointer.
14408 (build_reference_type_for_mode): When building a reference type,
14409 also build a canonical type reference.
14410 (build_index_type): When we can't hash an index type (e.g.,
14411 because its maximum value is negative), the index type requires
14412 structural equality tests.
14413 (build_array_type): Build the canonical form of an array type.
14414 (build_function_type): Function types require structural equality,
14415 because they contain default arguments, attributes, etc.
14416 (build_method_type_directly): Ditto for method types.
14417 (build_offset_type): Build the canonical offset type.
