18969         * c-common.c (c_common_nodes_and_builtins): Since variants of
18970         void_type_node get built before it is given a name, we need to
18971         give those variants the name, too.
18972         (complete_array_type): We need to work with the canonical main
18973         type of the array, from which we will build the qualified version.
18974         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
18975         * print-tree.c (print_node): Display canonical type information
18976         for each type.
18977         * stor-layout.c (layout_type): When we don't know the
18978         alignment of a type for which we're building an array, we end up
18979         guessing wrong, so make the type require structural equality.
18980         * tree.c (make_node_stat): When we build a new type, it is its
18981         own canonical type.
18982         (build_type_attribute_qual_variant): When building an attribute
18983         variant, its canonical type is the non-attribute variant. However,
18984         if the attributes are target-dependent and they differ, we need to
18985         use structural equality checks for this type.
18986         (build_qualified_type): A qualified type is not equivalent to its
18987         unqualified variant; set the canonical type appropriately.
18988         (build_distinct_type_copy): When building a distinct type from
18989         another type, the new type is its own canonical type.
18990         (build_variant_type_copy): When building a new type variant, we
18991         assume that it is equivalent to the original type.
18992         (build_pointer_type_for_mode): When building a pointer type, also
18993         build a canonical type pointer.
18994         (build_reference_type_for_mode): When building a reference type,
18995         also build a canonical type reference.
18996         (build_index_type): When we can't hash an index type (e.g.,
18997         because its maximum value is negative), the index type requires
18998         structural equality tests.
18999         (build_array_type): Build the canonical form of an array type.
19000         (build_function_type): Function types require structural equality,
19001         because they contain default arguments, attributes, etc.
19002         (build_method_type_directly): Ditto for method types.
19003         (build_offset_type): Build the canonical offset type.
19004         (build_complex_type): Build the canonical vector type.
19005         (make_vector_type): Build the canonical vector type.
19006         * tree.h (TYPE_CANONICAL): New.

19008         (SET_TYPE_STRUCTURAL_EQUALITY): New.
19009         (struct tree_type): Added "canonical" field.
