25244 * c-common.c (c_common_nodes_and_builtins): Since variants of
25245 void_type_node get built before it is given a name, we need to
25246 give those variants the name, too.
25247 (complete_array_type): We need to work with the canonical main
25248 type of the array, from which we will build the qualified version.

25252 * stor-layout.c (layout_type): When we don't know the
25253 alignment of a type for which we're building an array, we end up
25254 guessing wrong, so make the type require structural equality.
25255 * tree.c (make_node_stat): When we build a new type, it is its
25256 own canonical type.
25257 (build_type_attribute_qual_variant): When building an attribute
25258 variant, its canonical type is the non-attribute variant. However,
25259 if the attributes are target-dependent and they differ, we need to
25260 use structural equality checks for this type.
25261 (build_qualified_type): A qualified type is not equivalent to its
25262 unqualified variant; set the canonical type appropriately.
25263 (build_distinct_type_copy): When building a distinct type from
25264 another type, the new type is its own canonical type.
25265 (build_variant_type_copy): When building a new type variant, we
25266 assume that it is equivalent to the original type.
25267 (build_pointer_type_for_mode): When building a pointer type, also
25268 build a canonical type pointer.
25269 (build_reference_type_for_mode): When building a reference type,
25270 also build a canonical type reference.
25271 (build_index_type): When we can't hash an index type (e.g.,
25272 because its maximum value is negative), the index type requires
25273 structural equality tests.
25274 (build_array_type): Build the canonical form of an array type.
25275 (build_function_type): Function types require structural equality,
25276 because they contain default arguments, attributes, etc.
25277 (build_method_type_directly): Ditto for method types.
