22777 * c-common.c (c_common_nodes_and_builtins): Since variants of
22778 void_type_node get built before it is given a name, we need to
22779 give those variants the name, too.
22780 (complete_array_type): We need to work with the canonical main
22781 type of the array, from which we will build the qualified version.
22782 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
22783 * print-tree.c (print_node): Display canonical type information
22785 * stor-layout.c (layout_type): When we don't know the
22786 alignment of a type for which we're building an array, we end up
22787 guessing wrong, so make the type require structural equality.
22788 * tree.c (make_node_stat): When we build a new type, it is its
22789 own canonical type.
22790 (build_type_attribute_qual_variant): When building an attribute
22791 variant, its canonical type is the non-attribute variant. However,
22792 if the attributes are target-dependent and they differ, we need to
22793 use structural equality checks for this type.
22794 (build_qualified_type): A qualified type is not equivalent to its
22795 unqualified variant; set the canonical type appropriately.
22796 (build_distinct_type_copy): When building a distinct type from
22797 another type, the new type is its own canonical type.
22798 (build_variant_type_copy): When building a new type variant, we
22799 assume that it is equivalent to the original type.
22800 (build_pointer_type_for_mode): When building a pointer type, also
22801 build a canonical type pointer.
22802 (build_reference_type_for_mode): When building a reference type,
22803 also build a canonical type reference.
22804 (build_index_type): When we can't hash an index type (e.g.,
22805 because its maximum value is negative), the index type requires
22806 structural equality tests.
22807 (build_array_type): Build the canonical form of an array type.
22808 (build_function_type): Function types require structural equality,
22809 because they contain default arguments, attributes, etc.
22810 (build_method_type_directly): Ditto for method types.
22811 (build_offset_type): Build the canonical offset type.
