12064
12065         * c-common.c (c_common_nodes_and_builtins): Since variants of
12066         void_type_node get built before it is given a name, we need to
12067         give those variants the name, too.
12068         (complete_array_type): We need to work with the canonical main
12069         type of the array, from which we will build the qualified version.

12071         * print-tree.c (print_node): Display canonical type information
12072         for each type.

12074         alignment of a type for which we're building an array, we end up
12075         guessing wrong, so make the type require structural equality.
12076         * tree.c (make_node_stat): When we build a new type, it is its
12077         own canonical type.
12078         (build_type_attribute_qual_variant): When building an attribute
12079         variant, its canonical type is the non-attribute variant. However,
12080         if the attributes are target-dependent and they differ, we need to
12081         use structural equality checks for this type.
12082         (build_qualified_type): A qualified type is not equivalent to its
12083         unqualified variant; set the canonical type appropriately.
12084         (build_distinct_type_copy): When building a distinct type from
12085         another type, the new type is its own canonical type.

12091         also build a canonical type reference.
12092         (build_index_type): When we can't hash an index type (e.g.,
12093         because its maximum value is negative), the index type requires
12094         structural equality tests.
12095         (build_array_type): Build the canonical form of an array type.
12096         (build_function_type): Function types require structural equality,
12097         because they contain default arguments, attributes, etc.
12098         (build_method_type_directly): Ditto for method types.
12099         (build_offset_type): Build the canonical offset type.
