11056 * c-common.c (c_common_nodes_and_builtins): Since variants of
11057 void_type_node get built before it is given a name, we need to
11058 give those variants the name, too.
11059 (complete_array_type): We need to work with the canonical main
11060 type of the array, from which we will build the qualified version.

11062 * print-tree.c (print_node): Display canonical type information
11064 * stor-layout.c (layout_type): When we don't know the
11065 alignment of a type for which we're building an array, we end up
11066 guessing wrong, so make the type require structural equality.
11067 * tree.c (make_node_stat): When we build a new type, it is its
11068 own canonical type.
11069 (build_type_attribute_qual_variant): When building an attribute
11070 variant, its canonical type is the non-attribute variant. However,
11071 if the attributes are target-dependent and they differ, we need to
11072 use structural equality checks for this type.
11073 (build_qualified_type): A qualified type is not equivalent to its
11074 unqualified variant; set the canonical type appropriately.
11075 (build_distinct_type_copy): When building a distinct type from
11076 another type, the new type is its own canonical type.
11077 (build_variant_type_copy): When building a new type variant, we
11078 assume that it is equivalent to the original type.
11079 (build_pointer_type_for_mode): When building a pointer type, also
11080 build a canonical type pointer.
11081 (build_reference_type_for_mode): When building a reference type,
11082 also build a canonical type reference.
11083 (build_index_type): When we can't hash an index type (e.g.,
11084 because its maximum value is negative), the index type requires
11085 structural equality tests.
11086 (build_array_type): Build the canonical form of an array type.
11087 (build_function_type): Function types require structural equality,
11088 because they contain default arguments, attributes, etc.
11089 (build_method_type_directly): Ditto for method types.
11090 (build_offset_type): Build the canonical offset type.
