29438 * print-tree.c (print_node): Display canonical type information
29440 * stor-layout.c (layout_type): When we don't know the
29441 alignment of a type for which we're building an array, we end up
29442 guessing wrong, so make the type require structural equality.
29443 * tree.c (make_node_stat): When we build a new type, it is its
29444 own canonical type.
29445 (build_type_attribute_qual_variant): When building an attribute
29446 variant, its canonical type is the non-attribute variant. However,
29447 if the attributes are target-dependent and they differ, we need to
29448 use structural equality checks for this type.
29449 (build_qualified_type): A qualified type is not equivalent to its
29450 unqualified variant; set the canonical type appropriately.
29451 (build_distinct_type_copy): When building a distinct type from
29452 another type, the new type is its own canonical type.
29453 (build_variant_type_copy): When building a new type variant, we
29454 assume that it is equivalent to the original type.
29455 (build_pointer_type_for_mode): When building a pointer type, also
29456 build a canonical type pointer.
29457 (build_reference_type_for_mode): When building a reference type,
29458 also build a canonical type reference.
29459 (build_index_type): When we can't hash an index type (e.g.,
29460 because its maximum value is negative), the index type requires
29461 structural equality tests.
29462 (build_array_type): Build the canonical form of an array type.
29463 (build_function_type): Function types require structural equality,
29464 because they contain default arguments, attributes, etc.
29465 (build_method_type_directly): Ditto for method types.
