29030 * c-common.c (c_common_nodes_and_builtins): Since variants of
29031 void_type_node get built before it is given a name, we need to
29032 give those variants the name, too.
29033 (complete_array_type): We need to work with the canonical main

29038 * stor-layout.c (layout_type): When we don't know the
29039 alignment of a type for which we're building an array, we end up
29040 guessing wrong, so make the type require structural equality.

29042 own canonical type.
29043 (build_type_attribute_qual_variant): When building an attribute
29044 variant, its canonical type is the non-attribute variant. However,
29045 if the attributes are target-dependent and they differ, we need to
29046 use structural equality checks for this type.
29047 (build_qualified_type): A qualified type is not equivalent to its
29048 unqualified variant; set the canonical type appropriately.
29049 (build_distinct_type_copy): When building a distinct type from
29050 another type, the new type is its own canonical type.
29051 (build_variant_type_copy): When building a new type variant, we
29052 assume that it is equivalent to the original type.
29053 (build_pointer_type_for_mode): When building a pointer type, also
29054 build a canonical type pointer.
29055 (build_reference_type_for_mode): When building a reference type,
29056 also build a canonical type reference.
29057 (build_index_type): When we can't hash an index type (e.g.,
29058 because its maximum value is negative), the index type requires
29059 structural equality tests.
29060 (build_array_type): Build the canonical form of an array type.
29061 (build_function_type): Function types require structural equality,
29062 because they contain default arguments, attributes, etc.
