31227 * c-common.c (c_common_nodes_and_builtins): Since variants of
31228 void_type_node get built before it is given a name, we need to
31229 give those variants the name, too.
31230 (complete_array_type): We need to work with the canonical main

31235 * stor-layout.c (layout_type): When we don't know the
31236 alignment of a type for which we're building an array, we end up
31237 guessing wrong, so make the type require structural equality.
31238 * tree.c (make_node_stat): When we build a new type, it is its
31239 own canonical type.
31240 (build_type_attribute_qual_variant): When building an attribute
31241 variant, its canonical type is the non-attribute variant. However,
31242 if the attributes are target-dependent and they differ, we need to
31243 use structural equality checks for this type.
31244 (build_qualified_type): A qualified type is not equivalent to its
31245 unqualified variant; set the canonical type appropriately.
31246 (build_distinct_type_copy): When building a distinct type from
31247 another type, the new type is its own canonical type.
31248 (build_variant_type_copy): When building a new type variant, we
31249 assume that it is equivalent to the original type.
31250 (build_pointer_type_for_mode): When building a pointer type, also
31251 build a canonical type pointer.
31252 (build_reference_type_for_mode): When building a reference type,
31253 also build a canonical type reference.
31254 (build_index_type): When we can't hash an index type (e.g.,
31255 because its maximum value is negative), the index type requires
31256 structural equality tests.
31257 (build_array_type): Build the canonical form of an array type.
31258 (build_function_type): Function types require structural equality,
31259 because they contain default arguments, attributes, etc.
31260 (build_method_type_directly): Ditto for method types.
