31264 * c-common.c (c_common_nodes_and_builtins): Since variants of
31265 void_type_node get built before it is given a name, we need to
31266 give those variants the name, too.
31267 (complete_array_type): We need to work with the canonical main
31268 type of the array, from which we will build the qualified version.

31270 * print-tree.c (print_node): Display canonical type information
31272 * stor-layout.c (layout_type): When we don't know the
31273 alignment of a type for which we're building an array, we end up
31274 guessing wrong, so make the type require structural equality.
31275 * tree.c (make_node_stat): When we build a new type, it is its
31276 own canonical type.
31277 (build_type_attribute_qual_variant): When building an attribute
31278 variant, its canonical type is the non-attribute variant. However,
31279 if the attributes are target-dependent and they differ, we need to
31280 use structural equality checks for this type.
31281 (build_qualified_type): A qualified type is not equivalent to its
31282 unqualified variant; set the canonical type appropriately.
31283 (build_distinct_type_copy): When building a distinct type from
31284 another type, the new type is its own canonical type.
31285 (build_variant_type_copy): When building a new type variant, we
31286 assume that it is equivalent to the original type.
31287 (build_pointer_type_for_mode): When building a pointer type, also
31288 build a canonical type pointer.
31289 (build_reference_type_for_mode): When building a reference type,
31290 also build a canonical type reference.
31291 (build_index_type): When we can't hash an index type (e.g.,
31292 because its maximum value is negative), the index type requires
31293 structural equality tests.
31294 (build_array_type): Build the canonical form of an array type.
31295 (build_function_type): Function types require structural equality,
31296 because they contain default arguments, attributes, etc.
31297 (build_method_type_directly): Ditto for method types.
31298 (build_offset_type): Build the canonical offset type.
31299 (build_complex_type): Build the canonical vector type.
31300 (make_vector_type): Build the canonical vector type.
