12705 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
12706
12707         * c-common.c (c_common_nodes_and_builtins): Since variants of
12708         void_type_node get built before it is given a name, we need to
12709         give those variants the name, too.
12710         (complete_array_type): We need to work with the canonical main
12711         type of the array, from which we will build the qualified version.
12712         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
12713         * print-tree.c (print_node): Display canonical type information
12714         for each type.
12715         * stor-layout.c (layout_type): When we don't know the
12716         alignment of a type for which we're building an array, we end up
12717         guessing wrong, so make the type require structural equality.
12718         * tree.c (make_node_stat): When we build a new type, it is its
12719         own canonical type.
12720         (build_type_attribute_qual_variant): When building an attribute
12721         variant, its canonical type is the non-attribute variant. However,
12722         if the attributes are target-dependent and they differ, we need to
12723         use structural equality checks for this type.
12724         (build_qualified_type): A qualified type is not equivalent to its
12725         unqualified variant; set the canonical type appropriately.
12726         (build_distinct_type_copy): When building a distinct type from
12727         another type, the new type is its own canonical type.
12728         (build_variant_type_copy): When building a new type variant, we
12729         assume that it is equivalent to the original type.
12730         (build_pointer_type_for_mode): When building a pointer type, also
12731         build a canonical type pointer.
12732         (build_reference_type_for_mode): When building a reference type,
12733         also build a canonical type reference.
12734         (build_index_type): When we can't hash an index type (e.g.,
12735         because its maximum value is negative), the index type requires
12736         structural equality tests.
12737         (build_array_type): Build the canonical form of an array type.
12738         (build_function_type): Function types require structural equality,
12739         because they contain default arguments, attributes, etc.
12740         (build_method_type_directly): Ditto for method types.
12741         (build_offset_type): Build the canonical offset type.
12742         (build_complex_type): Build the canonical vector type.
12743         (make_vector_type): Build the canonical vector type.
12744         * tree.h (TYPE_CANONICAL): New.
12745         (TYPE_STRUCTURAL_EQUALITY_P): New.
12746         (SET_TYPE_STRUCTURAL_EQUALITY): New.
12747         (struct tree_type): Added "canonical" field.
12748         * params.h (VERIFY_CANONICAL_TYPES): New.
12749         * doc/c-tree.texi (TYPE_CANONICAL): Document.
12750         (TYPE_STRUCTURAL_EQUALITY_P): Document.
12751         (SET_TYPE_STRUCTURAL_EQUALITY): Document.
12752         * doc/invoke.texi (verify-canonical-types): Document --param
12753         parameter for verifying canonical types.
