  59 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
  60
  61         * c-common.c(c_common_nodes_and_builtins): Since variants of
  62         void_type_node get built before it is given a name, we need to
  63         give those variants the name, too.
  64         (complete_array_type): We need to work with the canonical main
  65         type of the array, from which we will build the qualified version.

  68         for each type.
  69         * stor-layout.c (layout_type): When we don't know the
  70         alignment of a type for which we're building an array, we end up
  71         guessing wrong, so make the type require structural equality.
  72         * tree.c (make_node_stat): When we build a new type, it is its
  73         own canonical type.
  74         (build_type_attribute_qual_variant): When building an attribute
  75         variant, its canonical type is the non-attribute variant. However,
  76         if the attributes are target-dependent and they differ, we need to
  77         use structural equality checks for this type.
  78         (build_qualified_type): A qualified type is not equivalent to its
  79         unqualified variant; set the canonical type appropriately.
  80         (build_distinct_type_copy): When building a distinct type from
  81         another type, the new type is its own canonical type.
  82         (build_variant_type_copy): When building a new type variant, we
  83         assume that it is equivalent to the original type.

  85         build a canonical type pointer.

  87         also build a canonical type reference.
  88         (build_index_type): When we can't hash an index type (e.g.,
  89         because its maximum value is negative), the index type requires
  90         structural equality tests.
  91         (build_array_type): Build the canonical form of an array type.
  92         (build_function_type): Function types require structural equality,
  93         because they contain default arguments, attributes, etc.
  94         (build_method_type_directly): Ditto for method types.
  95         (build_offset_type): Build the canonical offset type.
