12402
12403         * c-common.c (c_common_nodes_and_builtins): Since variants of
12404         void_type_node get built before it is given a name, we need to
12405         give those variants the name, too.
12406         (complete_array_type): We need to work with the canonical main
12407         type of the array, from which we will build the qualified version.

12409         * print-tree.c (print_node): Display canonical type information
12410         for each type.

12412         alignment of a type for which we're building an array, we end up
12413         guessing wrong, so make the type require structural equality.
12414         * tree.c (make_node_stat): When we build a new type, it is its
12415         own canonical type.
12416         (build_type_attribute_qual_variant): When building an attribute
12417         variant, its canonical type is the non-attribute variant. However,
12418         if the attributes are target-dependent and they differ, we need to
12419         use structural equality checks for this type.
12420         (build_qualified_type): A qualified type is not equivalent to its
12421         unqualified variant; set the canonical type appropriately.
12422         (build_distinct_type_copy): When building a distinct type from
12423         another type, the new type is its own canonical type.
12424         (build_variant_type_copy): When building a new type variant, we
12425         assume that it is equivalent to the original type.

12429         also build a canonical type reference.
12430         (build_index_type): When we can't hash an index type (e.g.,
12431         because its maximum value is negative), the index type requires
12432         structural equality tests.
12433         (build_array_type): Build the canonical form of an array type.
12434         (build_function_type): Function types require structural equality,
12435         because they contain default arguments, attributes, etc.
12436         (build_method_type_directly): Ditto for method types.
12437         (build_offset_type): Build the canonical offset type.
