2190
2191         * c-common.c(c_common_nodes_and_builtins): Since variants of
2192         void_type_node get built before it is given a name, we need to
2193         give those variants the name, too.
2194         (complete_array_type): We need to work with the canonical main
2195         type of the array, from which we will build the qualified version.

2197         * print-tree.c (print_node): Display canonical type information
2198         for each type.
2199         * stor-layout.c (layout_type): When we don't know the
2200         alignment of a type for which we're building an array, we end up
2201         guessing wrong, so make the type require structural equality.
2202         * tree.c (make_node_stat): When we build a new type, it is its
2203         own canonical type.
2204         (build_type_attribute_qual_variant): When building an attribute
2205         variant, its canonical type is the non-attribute variant. However,
2206         if the attributes are target-dependent and they differ, we need to
2207         use structural equality checks for this type.
2208         (build_qualified_type): A qualified type is not equivalent to its
2209         unqualified variant; set the canonical type appropriately.
2210         (build_distinct_type_copy): When building a distinct type from
2211         another type, the new type is its own canonical type.
2212         (build_variant_type_copy): When building a new type variant, we
2213         assume that it is equivalent to the original type.

2215         build a canonical type pointer.

2217         also build a canonical type reference.
2218         (build_index_type): When we can't hash an index type (e.g.,
2219         because its maximum value is negative), the index type requires
2220         structural equality tests.
2221         (build_array_type): Build the canonical form of an array type.
2222         (build_function_type): Function types require structural equality,
2223         because they contain default arguments, attributes, etc.
2224         (build_method_type_directly): Ditto for method types.
2225         (build_offset_type): Build the canonical offset type.

2237         parameter for verifying canonical types.
