8852 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
8854 * c-common.c (c_common_nodes_and_builtins): Since variants of
8855 void_type_node get built before it is given a name, we need to
8856 give those variants the name, too.
8857 (complete_array_type): We need to work with the canonical main
8858 type of the array, from which we will build the qualified version.
8859 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
8860 * print-tree.c (print_node): Display canonical type information
8862 * stor-layout.c (layout_type): When we don't know the
8863 alignment of a type for which we're building an array, we end up
8864 guessing wrong, so make the type require structural equality.
8865 * tree.c (make_node_stat): When we build a new type, it is its
8867 (build_type_attribute_qual_variant): When building an attribute
8868 variant, its canonical type is the non-attribute variant. However,
8869 if the attributes are target-dependent and they differ, we need to
8870 use structural equality checks for this type.
8871 (build_qualified_type): A qualified type is not equivalent to its
8872 unqualified variant; set the canonical type appropriately.
8873 (build_distinct_type_copy): When building a distinct type from
8874 another type, the new type is its own canonical type.
8875 (build_variant_type_copy): When building a new type variant, we
8876 assume that it is equivalent to the original type.
8877 (build_pointer_type_for_mode): When building a pointer type, also
8878 build a canonical type pointer.
8879 (build_reference_type_for_mode): When building a reference type,
8880 also build a canonical type reference.
8881 (build_index_type): When we can't hash an index type (e.g.,
8882 because its maximum value is negative), the index type requires
8883 structural equality tests.
8884 (build_array_type): Build the canonical form of an array type.
8885 (build_function_type): Function types require structural equality,
8886 because they contain default arguments, attributes, etc.
8887 (build_method_type_directly): Ditto for method types.
8888 (build_offset_type): Build the canonical offset type.
8889 (build_complex_type): Build the canonical vector type.
8890 (make_vector_type): Build the canonical vector type.
