31271 * c-common.c (c_common_nodes_and_builtins): Since variants of
31272 void_type_node get built before it is given a name, we need to
31273 give those variants the name, too.
31274 (complete_array_type): We need to work with the canonical main
31275 type of the array, from which we will build the qualified version.

31277 * print-tree.c (print_node): Display canonical type information
31279 * stor-layout.c (layout_type): When we don't know the
31280 alignment of a type for which we're building an array, we end up
31281 guessing wrong, so make the type require structural equality.
31282 * tree.c (make_node_stat): When we build a new type, it is its
31283 own canonical type.
31284 (build_type_attribute_qual_variant): When building an attribute
31285 variant, its canonical type is the non-attribute variant. However,
31286 if the attributes are target-dependent and they differ, we need to
31287 use structural equality checks for this type.
31288 (build_qualified_type): A qualified type is not equivalent to its
31289 unqualified variant; set the canonical type appropriately.
31290 (build_distinct_type_copy): When building a distinct type from
31291 another type, the new type is its own canonical type.
31292 (build_variant_type_copy): When building a new type variant, we
31293 assume that it is equivalent to the original type.
31294 (build_pointer_type_for_mode): When building a pointer type, also
31295 build a canonical type pointer.
31296 (build_reference_type_for_mode): When building a reference type,
31297 also build a canonical type reference.
31298 (build_index_type): When we can't hash an index type (e.g.,
31299 because its maximum value is negative), the index type requires
31300 structural equality tests.
31301 (build_array_type): Build the canonical form of an array type.
31302 (build_function_type): Function types require structural equality,
31303 because they contain default arguments, attributes, etc.
31304 (build_method_type_directly): Ditto for method types.
31305 (build_offset_type): Build the canonical offset type.
31306 (build_complex_type): Build the canonical vector type.
31307 (make_vector_type): Build the canonical vector type.
