34291 * c-common.c (c_common_nodes_and_builtins): Since variants of
34292 void_type_node get built before it is given a name, we need to
34293 give those variants the name, too.
34294 (complete_array_type): We need to work with the canonical main
34295 type of the array, from which we will build the qualified version.

34297 * print-tree.c (print_node): Display canonical type information
34299 * stor-layout.c (layout_type): When we don't know the
34300 alignment of a type for which we're building an array, we end up
34301 guessing wrong, so make the type require structural equality.
34302 * tree.c (make_node_stat): When we build a new type, it is its
34303 own canonical type.
34304 (build_type_attribute_qual_variant): When building an attribute
34305 variant, its canonical type is the non-attribute variant. However,
34306 if the attributes are target-dependent and they differ, we need to
34307 use structural equality checks for this type.
34308 (build_qualified_type): A qualified type is not equivalent to its
34309 unqualified variant; set the canonical type appropriately.
34310 (build_distinct_type_copy): When building a distinct type from
34311 another type, the new type is its own canonical type.
34312 (build_variant_type_copy): When building a new type variant, we
34313 assume that it is equivalent to the original type.
34314 (build_pointer_type_for_mode): When building a pointer type, also
34315 build a canonical type pointer.
34316 (build_reference_type_for_mode): When building a reference type,
34317 also build a canonical type reference.
34318 (build_index_type): When we can't hash an index type (e.g.,
34319 because its maximum value is negative), the index type requires
34320 structural equality tests.
34321 (build_array_type): Build the canonical form of an array type.
34322 (build_function_type): Function types require structural equality,
34323 because they contain default arguments, attributes, etc.
34324 (build_method_type_directly): Ditto for method types.
