4780 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
4782 * c-common.c (c_common_nodes_and_builtins): Since variants of
4783 void_type_node get built before it is given a name, we need to
4784 give those variants the name, too.
4785 (complete_array_type): We need to work with the canonical main
4786 type of the array, from which we will build the qualified version.
4787 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
4788 * print-tree.c (print_node): Display canonical type information
4790 * stor-layout.c (layout_type): When we don't know the
4791 alignment of a type for which we're building an array, we end up
4792 guessing wrong, so make the type require structural equality.
4793 * tree.c (make_node_stat): When we build a new type, it is its
4795 (build_type_attribute_qual_variant): When building an attribute
4796 variant, its canonical type is the non-attribute variant. However,
4797 if the attributes are target-dependent and they differ, we need to
4798 use structural equality checks for this type.
4799 (build_qualified_type): A qualified type is not equivalent to its
4800 unqualified variant; set the canonical type appropriately.
4801 (build_distinct_type_copy): When building a distinct type from
4802 another type, the new type is its own canonical type.
4803 (build_variant_type_copy): When building a new type variant, we
4804 assume that it is equivalent to the original type.
4805 (build_pointer_type_for_mode): When building a pointer type, also
4806 build a canonical type pointer.
4807 (build_reference_type_for_mode): When building a reference type,
4808 also build a canonical type reference.
4809 (build_index_type): When we can't hash an index type (e.g.,
4810 because its maximum value is negative), the index type requires
4811 structural equality tests.
4812 (build_array_type): Build the canonical form of an array type.
4813 (build_function_type): Function types require structural equality,
4814 because they contain default arguments, attributes, etc.
4815 (build_method_type_directly): Ditto for method types.
4816 (build_offset_type): Build the canonical offset type.
4817 (build_complex_type): Build the canonical vector type.
4818 (make_vector_type): Build the canonical vector type.
4819 * tree.h (TYPE_CANONICAL): New.

4828 parameter for verifying canonical types.
