11735
11736         * c-common.c (c_common_nodes_and_builtins): Since variants of
11737         void_type_node get built before it is given a name, we need to
11738         give those variants the name, too.
11739         (complete_array_type): We need to work with the canonical main
11740         type of the array, from which we will build the qualified version.
11741         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
11742         * print-tree.c (print_node): Display canonical type information
11743         for each type.
11744         * stor-layout.c (layout_type): When we don't know the
11745         alignment of a type for which we're building an array, we end up
11746         guessing wrong, so make the type require structural equality.
11747         * tree.c (make_node_stat): When we build a new type, it is its
11748         own canonical type.
11749         (build_type_attribute_qual_variant): When building an attribute
11750         variant, its canonical type is the non-attribute variant. However,
11751         if the attributes are target-dependent and they differ, we need to
11752         use structural equality checks for this type.
11753         (build_qualified_type): A qualified type is not equivalent to its
11754         unqualified variant; set the canonical type appropriately.
11755         (build_distinct_type_copy): When building a distinct type from
11756         another type, the new type is its own canonical type.
11757         (build_variant_type_copy): When building a new type variant, we
11758         assume that it is equivalent to the original type.
11759         (build_pointer_type_for_mode): When building a pointer type, also
11760         build a canonical type pointer.
11761         (build_reference_type_for_mode): When building a reference type,
11762         also build a canonical type reference.
11763         (build_index_type): When we can't hash an index type (e.g.,
11764         because its maximum value is negative), the index type requires
11765         structural equality tests.
11766         (build_array_type): Build the canonical form of an array type.
11767         (build_function_type): Function types require structural equality,
11768         because they contain default arguments, attributes, etc.
11769         (build_method_type_directly): Ditto for method types.
11770         (build_offset_type): Build the canonical offset type.
11771         (build_complex_type): Build the canonical vector type.
11772         (make_vector_type): Build the canonical vector type.

11775         (SET_TYPE_STRUCTURAL_EQUALITY): New.
11776         (struct tree_type): Added "canonical" field.
11777         * params.h (VERIFY_CANONICAL_TYPES): New.
11778         * doc/c-tree.texi (TYPE_CANONICAL): Document.

11780         (SET_TYPE_STRUCTURAL_EQUALITY): Document.
11781         * doc/invoke.texi (verify-canonical-types): Document --param
11782         parameter for verifying canonical types.
