33438 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
33439 * print-tree.c (print_node): Display canonical type information
33441 * stor-layout.c (layout_type): When we don't know the
33442 alignment of a type for which we're building an array, we end up
33443 guessing wrong, so make the type require structural equality.
33444 * tree.c (make_node_stat): When we build a new type, it is its
33445 own canonical type.
33446 (build_type_attribute_qual_variant): When building an attribute
33447 variant, its canonical type is the non-attribute variant. However,
33448 if the attributes are target-dependent and they differ, we need to
33449 use structural equality checks for this type.
33450 (build_qualified_type): A qualified type is not equivalent to its
33451 unqualified variant; set the canonical type appropriately.
33452 (build_distinct_type_copy): When building a distinct type from
33453 another type, the new type is its own canonical type.
33454 (build_variant_type_copy): When building a new type variant, we
33455 assume that it is equivalent to the original type.
33456 (build_pointer_type_for_mode): When building a pointer type, also
33457 build a canonical type pointer.
33458 (build_reference_type_for_mode): When building a reference type,
33459 also build a canonical type reference.
33460 (build_index_type): When we can't hash an index type (e.g.,
33461 because its maximum value is negative), the index type requires
33462 structural equality tests.
33463 (build_array_type): Build the canonical form of an array type.
33464 (build_function_type): Function types require structural equality,
33465 because they contain default arguments, attributes, etc.
33466 (build_method_type_directly): Ditto for method types.
33467 (build_offset_type): Build the canonical offset type.
