1714 (complete_array_type): We need to work with the canonical main
1715 type of the array, from which we will build the qualified version.
1716 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
1717 * print-tree.c (print_node): Display canonical type information
1719 * stor-layout.c (layout_type): When we don't know the
1720 alignment of a type for which we're building an array, we end up
1721 guessing wrong, so make the type require structural equality.
1722 * tree.c (make_node_stat): When we build a new type, it is its
1724 (build_type_attribute_qual_variant): When building an attribute
1725 variant, its canonical type is the non-attribute variant. However,
1726 if the attributes are target-dependent and they differ, we need to
1727 use structural equality checks for this type.
1728 (build_qualified_type): A qualified type is not equivalent to its
1729 unqualified variant; set the canonical type appropriately.
1730 (build_distinct_type_copy): When building a distinct type from
1731 another type, the new type is its own canonical type.
1732 (build_variant_type_copy): When building a new type variant, we
1733 assume that it is equivalent to the original type.
1734 (build_pointer_type_for_mode): When building a pointer type, also
1735 build a canonical type pointer.
1736 (build_reference_type_for_mode): When building a reference type,
1737 also build a canonical type reference.
1738 (build_index_type): When we can't hash an index type (e.g.,
1739 because its maximum value is negative), the index type requires
1740 structural equality tests.
1741 (build_array_type): Build the canonical form of an array type.
1742 (build_function_type): Function types require structural equality,
1743 because they contain default arguments, attributes, etc.
1744 (build_method_type_directly): Ditto for method types.
1745 (build_offset_type): Build the canonical offset type.
1746 (build_complex_type): Build the canonical vector type.
1747 (make_vector_type): Build the canonical vector type.

1757 parameter for verifying canonical types.
