10807 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
10808
10809         * c-common.c (c_common_nodes_and_builtins): Since variants of
10810         void_type_node get built before it is given a name, we need to
10811         give those variants the name, too.
10812         (complete_array_type): We need to work with the canonical main
10813         type of the array, from which we will build the qualified version.
10814         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
10815         * print-tree.c (print_node): Display canonical type information
10816         for each type.
10817         * stor-layout.c (layout_type): When we don't know the
10818         alignment of a type for which we're building an array, we end up
10819         guessing wrong, so make the type require structural equality.
10820         * tree.c (make_node_stat): When we build a new type, it is its
10821         own canonical type.
10822         (build_type_attribute_qual_variant): When building an attribute
10823         variant, its canonical type is the non-attribute variant. However,
10824         if the attributes are target-dependent and they differ, we need to
10825         use structural equality checks for this type.
10826         (build_qualified_type): A qualified type is not equivalent to its
10827         unqualified variant; set the canonical type appropriately.
10828         (build_distinct_type_copy): When building a distinct type from
10829         another type, the new type is its own canonical type.
10830         (build_variant_type_copy): When building a new type variant, we
10831         assume that it is equivalent to the original type.
10832         (build_pointer_type_for_mode): When building a pointer type, also
10833         build a canonical type pointer.
10834         (build_reference_type_for_mode): When building a reference type,
10835         also build a canonical type reference.
10836         (build_index_type): When we can't hash an index type (e.g.,
10837         because its maximum value is negative), the index type requires
10838         structural equality tests.
10839         (build_array_type): Build the canonical form of an array type.
10840         (build_function_type): Function types require structural equality,
10841         because they contain default arguments, attributes, etc.
10842         (build_method_type_directly): Ditto for method types.
10843         (build_offset_type): Build the canonical offset type.
10844         (build_complex_type): Build the canonical vector type.
10845         (make_vector_type): Build the canonical vector type.
10846         * tree.h (TYPE_CANONICAL): New.
10847         (TYPE_STRUCTURAL_EQUALITY_P): New.
10848         (SET_TYPE_STRUCTURAL_EQUALITY): New.
10849         (struct tree_type): Added "canonical" field.
10850         * params.h (VERIFY_CANONICAL_TYPES): New.
10851         * doc/c-tree.texi (TYPE_CANONICAL): Document.
10852         (TYPE_STRUCTURAL_EQUALITY_P): Document.
10853         (SET_TYPE_STRUCTURAL_EQUALITY): Document.
10854         * doc/invoke.texi (verify-canonical-types): Document --param
10855         parameter for verifying canonical types.
