31257 * c-common.c (c_common_nodes_and_builtins): Since variants of
31258 void_type_node get built before it is given a name, we need to
31259 give those variants the name, too.

31265 * stor-layout.c (layout_type): When we don't know the
31266 alignment of a type for which we're building an array, we end up
31267 guessing wrong, so make the type require structural equality.
31268 * tree.c (make_node_stat): When we build a new type, it is its
31269 own canonical type.
31270 (build_type_attribute_qual_variant): When building an attribute
31271 variant, its canonical type is the non-attribute variant. However,
31272 if the attributes are target-dependent and they differ, we need to
31273 use structural equality checks for this type.
31274 (build_qualified_type): A qualified type is not equivalent to its
31275 unqualified variant; set the canonical type appropriately.
31276 (build_distinct_type_copy): When building a distinct type from
31277 another type, the new type is its own canonical type.
31278 (build_variant_type_copy): When building a new type variant, we
31279 assume that it is equivalent to the original type.
31280 (build_pointer_type_for_mode): When building a pointer type, also
31281 build a canonical type pointer.
31282 (build_reference_type_for_mode): When building a reference type,
31283 also build a canonical type reference.
31284 (build_index_type): When we can't hash an index type (e.g.,
31285 because its maximum value is negative), the index type requires
31286 structural equality tests.
31287 (build_array_type): Build the canonical form of an array type.
31288 (build_function_type): Function types require structural equality,
31289 because they contain default arguments, attributes, etc.
31290 (build_method_type_directly): Ditto for method types.
31291 (build_offset_type): Build the canonical offset type.
31292 (build_complex_type): Build the canonical vector type.
