9303 * c-common.c (c_common_nodes_and_builtins): Since variants of
9304 void_type_node get built before it is given a name, we need to
9305 give those variants the name, too.
9306 (complete_array_type): We need to work with the canonical main
9307 type of the array, from which we will build the qualified version.

9311 * stor-layout.c (layout_type): When we don't know the
9312 alignment of a type for which we're building an array, we end up
9313 guessing wrong, so make the type require structural equality.

9316 (build_type_attribute_qual_variant): When building an attribute
9317 variant, its canonical type is the non-attribute variant. However,
9318 if the attributes are target-dependent and they differ, we need to
9319 use structural equality checks for this type.
9320 (build_qualified_type): A qualified type is not equivalent to its
9321 unqualified variant; set the canonical type appropriately.
9322 (build_distinct_type_copy): When building a distinct type from
9323 another type, the new type is its own canonical type.
9324 (build_variant_type_copy): When building a new type variant, we
9325 assume that it is equivalent to the original type.
9326 (build_pointer_type_for_mode): When building a pointer type, also
9327 build a canonical type pointer.
9328 (build_reference_type_for_mode): When building a reference type,
9329 also build a canonical type reference.
9330 (build_index_type): When we can't hash an index type (e.g.,
9331 because its maximum value is negative), the index type requires
9332 structural equality tests.
9333 (build_array_type): Build the canonical form of an array type.
9334 (build_function_type): Function types require structural equality,
9335 because they contain default arguments, attributes, etc.
9336 (build_method_type_directly): Ditto for method types.
9337 (build_offset_type): Build the canonical offset type.
9338 (build_complex_type): Build the canonical vector type.
9339 (make_vector_type): Build the canonical vector type.

9349 parameter for verifying canonical types.
