11061 * c-common.c (c_common_nodes_and_builtins): Since variants of
11062 void_type_node get built before it is given a name, we need to
11063 give those variants the name, too.
11064 (complete_array_type): We need to work with the canonical main
11065 type of the array, from which we will build the qualified version.

11067 * print-tree.c (print_node): Display canonical type information
11069 * stor-layout.c (layout_type): When we don't know the
11070 alignment of a type for which we're building an array, we end up
11071 guessing wrong, so make the type require structural equality.
11072 * tree.c (make_node_stat): When we build a new type, it is its
11073 own canonical type.
11074 (build_type_attribute_qual_variant): When building an attribute
11075 variant, its canonical type is the non-attribute variant. However,
11076 if the attributes are target-dependent and they differ, we need to
11077 use structural equality checks for this type.
11078 (build_qualified_type): A qualified type is not equivalent to its
11079 unqualified variant; set the canonical type appropriately.
11080 (build_distinct_type_copy): When building a distinct type from
11081 another type, the new type is its own canonical type.
11082 (build_variant_type_copy): When building a new type variant, we
11083 assume that it is equivalent to the original type.
11084 (build_pointer_type_for_mode): When building a pointer type, also
11085 build a canonical type pointer.
11086 (build_reference_type_for_mode): When building a reference type,
11087 also build a canonical type reference.
11088 (build_index_type): When we can't hash an index type (e.g.,
11089 because its maximum value is negative), the index type requires
11090 structural equality tests.
11091 (build_array_type): Build the canonical form of an array type.
11092 (build_function_type): Function types require structural equality,
11093 because they contain default arguments, attributes, etc.
11094 (build_method_type_directly): Ditto for method types.
11095 (build_offset_type): Build the canonical offset type.
11096 (build_complex_type): Build the canonical vector type.
