12384
12385         * c-common.c (c_common_nodes_and_builtins): Since variants of
12386         void_type_node get built before it is given a name, we need to
12387         give those variants the name, too.
12388         (complete_array_type): We need to work with the canonical main
12389         type of the array, from which we will build the qualified version.

12391         * print-tree.c (print_node): Display canonical type information
12392         for each type.
12393         * stor-layout.c (layout_type): When we don't know the
12394         alignment of a type for which we're building an array, we end up
12395         guessing wrong, so make the type require structural equality.
12396         * tree.c (make_node_stat): When we build a new type, it is its
12397         own canonical type.
12398         (build_type_attribute_qual_variant): When building an attribute
12399         variant, its canonical type is the non-attribute variant. However,
12400         if the attributes are target-dependent and they differ, we need to
12401         use structural equality checks for this type.
12402         (build_qualified_type): A qualified type is not equivalent to its
12403         unqualified variant; set the canonical type appropriately.
12404         (build_distinct_type_copy): When building a distinct type from
12405         another type, the new type is its own canonical type.
12406         (build_variant_type_copy): When building a new type variant, we
12407         assume that it is equivalent to the original type.

12409         build a canonical type pointer.

12411         also build a canonical type reference.
12412         (build_index_type): When we can't hash an index type (e.g.,
12413         because its maximum value is negative), the index type requires
12414         structural equality tests.
12415         (build_array_type): Build the canonical form of an array type.
12416         (build_function_type): Function types require structural equality,
12417         because they contain default arguments, attributes, etc.
12418         (build_method_type_directly): Ditto for method types.
12419         (build_offset_type): Build the canonical offset type.

12431         parameter for verifying canonical types.
