17367 * c-common.c (c_common_nodes_and_builtins): Since variants of
17368 void_type_node get built before it is given a name, we need to
17369 give those variants the name, too.
17370 (complete_array_type): We need to work with the canonical main
17371 type of the array, from which we will build the qualified version.

17373 * print-tree.c (print_node): Display canonical type information
17375 * stor-layout.c (layout_type): When we don't know the
17376 alignment of a type for which we're building an array, we end up
17377 guessing wrong, so make the type require structural equality.
17378 * tree.c (make_node_stat): When we build a new type, it is its
17379 own canonical type.
17380 (build_type_attribute_qual_variant): When building an attribute
17381 variant, its canonical type is the non-attribute variant. However,
17382 if the attributes are target-dependent and they differ, we need to
17383 use structural equality checks for this type.
17384 (build_qualified_type): A qualified type is not equivalent to its
17385 unqualified variant; set the canonical type appropriately.
17386 (build_distinct_type_copy): When building a distinct type from
17387 another type, the new type is its own canonical type.
17388 (build_variant_type_copy): When building a new type variant, we
17389 assume that it is equivalent to the original type.
17390 (build_pointer_type_for_mode): When building a pointer type, also
17391 build a canonical type pointer.
17392 (build_reference_type_for_mode): When building a reference type,
17393 also build a canonical type reference.
17394 (build_index_type): When we can't hash an index type (e.g.,
17395 because its maximum value is negative), the index type requires
17396 structural equality tests.
17397 (build_array_type): Build the canonical form of an array type.
17398 (build_function_type): Function types require structural equality,
17399 because they contain default arguments, attributes, etc.
17400 (build_method_type_directly): Ditto for method types.
