10813
10814         * c-common.c (c_common_nodes_and_builtins): Since variants of
10815         void_type_node get built before it is given a name, we need to
10816         give those variants the name, too.
10817         (complete_array_type): We need to work with the canonical main
10818         type of the array, from which we will build the qualified version.
10819         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
10820         * print-tree.c (print_node): Display canonical type information
10821         for each type.
10822         * stor-layout.c (layout_type): When we don't know the
10823         alignment of a type for which we're building an array, we end up
10824         guessing wrong, so make the type require structural equality.
10825         * tree.c (make_node_stat): When we build a new type, it is its
10826         own canonical type.
10827         (build_type_attribute_qual_variant): When building an attribute
10828         variant, its canonical type is the non-attribute variant. However,
10829         if the attributes are target-dependent and they differ, we need to
10830         use structural equality checks for this type.
10831         (build_qualified_type): A qualified type is not equivalent to its
10832         unqualified variant; set the canonical type appropriately.
10833         (build_distinct_type_copy): When building a distinct type from
10834         another type, the new type is its own canonical type.
10835         (build_variant_type_copy): When building a new type variant, we
10836         assume that it is equivalent to the original type.
10837         (build_pointer_type_for_mode): When building a pointer type, also
10838         build a canonical type pointer.
10839         (build_reference_type_for_mode): When building a reference type,
10840         also build a canonical type reference.
10841         (build_index_type): When we can't hash an index type (e.g.,
10842         because its maximum value is negative), the index type requires
10843         structural equality tests.
10844         (build_array_type): Build the canonical form of an array type.
10845         (build_function_type): Function types require structural equality,
10846         because they contain default arguments, attributes, etc.
10847         (build_method_type_directly): Ditto for method types.
10848         (build_offset_type): Build the canonical offset type.
10849         (build_complex_type): Build the canonical vector type.

10860         parameter for verifying canonical types.
