22383 * print-tree.c (print_node): Display canonical type information
22385 * stor-layout.c (layout_type): When we don't know the
22386 alignment of a type for which we're building an array, we end up
22387 guessing wrong, so make the type require structural equality.
22388 * tree.c (make_node_stat): When we build a new type, it is its
22389 own canonical type.
22390 (build_type_attribute_qual_variant): When building an attribute
22391 variant, its canonical type is the non-attribute variant. However,
22392 if the attributes are target-dependent and they differ, we need to
22393 use structural equality checks for this type.
22394 (build_qualified_type): A qualified type is not equivalent to its
22395 unqualified variant; set the canonical type appropriately.
22396 (build_distinct_type_copy): When building a distinct type from
22397 another type, the new type is its own canonical type.
22398 (build_variant_type_copy): When building a new type variant, we
22399 assume that it is equivalent to the original type.
22400 (build_pointer_type_for_mode): When building a pointer type, also
22401 build a canonical type pointer.
22402 (build_reference_type_for_mode): When building a reference type,
22403 also build a canonical type reference.
22404 (build_index_type): When we can't hash an index type (e.g.,
22405 because its maximum value is negative), the index type requires
22406 structural equality tests.
22407 (build_array_type): Build the canonical form of an array type.
22408 (build_function_type): Function types require structural equality,
22409 because they contain default arguments, attributes, etc.
22410 (build_method_type_directly): Ditto for method types.
