  53 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
  54
  55         * c-common.c(c_common_nodes_and_builtins): Since variants of
  56         void_type_node get built before it is given a name, we need to
  57         give those variants the name, too.
  58         (complete_array_type): We need to work with the canonical main
  59         type of the array, from which we will build the qualified version.
  60         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
  61         * print-tree.c (print_node): Display canonical type information
  62         for each type.
  63         * stor-layout.c (layout_type): When we don't know the
  64         alignment of a type for which we're building an array, we end up
  65         guessing wrong, so make the type require structural equality.
  66         * tree.c (make_node_stat): When we build a new type, it is its
  67         own canonical type.
  68         (build_type_attribute_qual_variant): When building an attribute
  69         variant, its canonical type is the non-attribute variant. However,
  70         if the attributes are target-dependent and they differ, we need to
  71         use structural equality checks for this type.
  72         (build_qualified_type): A qualified type is not equivalent to its
  73         unqualified variant; set the canonical type appropriately.
  74         (build_distinct_type_copy): When building a distinct type from
  75         another type, the new type is its own canonical type.
  76         (build_variant_type_copy): When building a new type variant, we
  77         assume that it is equivalent to the original type.
  78         (build_pointer_type_for_mode): When building a pointer type, also
  79         build a canonical type pointer.
  80         (build_reference_type_for_mode): When building a reference type,
  81         also build a canonical type reference.
  82         (build_index_type): When we can't hash an index type (e.g.,
  83         because its maximum value is negative), the index type requires
  84         structural equality tests.
  85         (build_array_type): Build the canonical form of an array type.
  86         (build_function_type): Function types require structural equality,
  87         because they contain default arguments, attributes, etc.
  88         (build_method_type_directly): Ditto for method types.
  89         (build_offset_type): Build the canonical offset type.
  90         (build_complex_type): Build the canonical vector type.

 101         parameter for verifying canonical types.
