12429
12430         * c-common.c (c_common_nodes_and_builtins): Since variants of
12431         void_type_node get built before it is given a name, we need to
12432         give those variants the name, too.
12433         (complete_array_type): We need to work with the canonical main
12434         type of the array, from which we will build the qualified version.

12436         * print-tree.c (print_node): Display canonical type information
12437         for each type.

12439         alignment of a type for which we're building an array, we end up
12440         guessing wrong, so make the type require structural equality.
12441         * tree.c (make_node_stat): When we build a new type, it is its
12442         own canonical type.
12443         (build_type_attribute_qual_variant): When building an attribute
12444         variant, its canonical type is the non-attribute variant. However,
12445         if the attributes are target-dependent and they differ, we need to
12446         use structural equality checks for this type.
12447         (build_qualified_type): A qualified type is not equivalent to its
12448         unqualified variant; set the canonical type appropriately.
12449         (build_distinct_type_copy): When building a distinct type from
12450         another type, the new type is its own canonical type.

12452         assume that it is equivalent to the original type.

12456         also build a canonical type reference.
12457         (build_index_type): When we can't hash an index type (e.g.,
12458         because its maximum value is negative), the index type requires
12459         structural equality tests.
12460         (build_array_type): Build the canonical form of an array type.
12461         (build_function_type): Function types require structural equality,
12462         because they contain default arguments, attributes, etc.
12463         (build_method_type_directly): Ditto for method types.
12464         (build_offset_type): Build the canonical offset type.

12476         parameter for verifying canonical types.
