6638 (complete_array_type): We need to work with the canonical main
6639 type of the array, from which we will build the qualified version.
6640 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
6641 * print-tree.c (print_node): Display canonical type information
6643 * stor-layout.c (layout_type): When we don't know the
6644 alignment of a type for which we're building an array, we end up
6645 guessing wrong, so make the type require structural equality.
6646 * tree.c (make_node_stat): When we build a new type, it is its
6648 (build_type_attribute_qual_variant): When building an attribute
6649 variant, its canonical type is the non-attribute variant. However,
6650 if the attributes are target-dependent and they differ, we need to
6651 use structural equality checks for this type.
6652 (build_qualified_type): A qualified type is not equivalent to its
6653 unqualified variant; set the canonical type appropriately.
6654 (build_distinct_type_copy): When building a distinct type from
6655 another type, the new type is its own canonical type.
6656 (build_variant_type_copy): When building a new type variant, we
6657 assume that it is equivalent to the original type.
6658 (build_pointer_type_for_mode): When building a pointer type, also
6659 build a canonical type pointer.
6660 (build_reference_type_for_mode): When building a reference type,
6661 also build a canonical type reference.
6662 (build_index_type): When we can't hash an index type (e.g.,
6663 because its maximum value is negative), the index type requires
6664 structural equality tests.
6665 (build_array_type): Build the canonical form of an array type.
6666 (build_function_type): Function types require structural equality,
6667 because they contain default arguments, attributes, etc.
6668 (build_method_type_directly): Ditto for method types.
6669 (build_offset_type): Build the canonical offset type.
6670 (build_complex_type): Build the canonical vector type.
6671 (make_vector_type): Build the canonical vector type.

6681 parameter for verifying canonical types.
