18227 * c-common.c (c_common_nodes_and_builtins): Since variants of
18228 void_type_node get built before it is given a name, we need to
18229 give those variants the name, too.
18230 (complete_array_type): We need to work with the canonical main

18235 * stor-layout.c (layout_type): When we don't know the
18236 alignment of a type for which we're building an array, we end up
18237 guessing wrong, so make the type require structural equality.
18238 * tree.c (make_node_stat): When we build a new type, it is its
18239 own canonical type.
18240 (build_type_attribute_qual_variant): When building an attribute
18241 variant, its canonical type is the non-attribute variant. However,
18242 if the attributes are target-dependent and they differ, we need to
18243 use structural equality checks for this type.
18244 (build_qualified_type): A qualified type is not equivalent to its
18245 unqualified variant; set the canonical type appropriately.
18246 (build_distinct_type_copy): When building a distinct type from
18247 another type, the new type is its own canonical type.
18248 (build_variant_type_copy): When building a new type variant, we
18249 assume that it is equivalent to the original type.
18250 (build_pointer_type_for_mode): When building a pointer type, also
18251 build a canonical type pointer.
18252 (build_reference_type_for_mode): When building a reference type,
18253 also build a canonical type reference.
18254 (build_index_type): When we can't hash an index type (e.g.,
18255 because its maximum value is negative), the index type requires
18256 structural equality tests.
18257 (build_array_type): Build the canonical form of an array type.
18258 (build_function_type): Function types require structural equality,
18259 because they contain default arguments, attributes, etc.
18260 (build_method_type_directly): Ditto for method types.
