10221
10222         * c-common.c (c_common_nodes_and_builtins): Since variants of
10223         void_type_node get built before it is given a name, we need to
10224         give those variants the name, too.
10225         (complete_array_type): We need to work with the canonical main
10226         type of the array, from which we will build the qualified version.

10231         alignment of a type for which we're building an array, we end up

10233         * tree.c (make_node_stat): When we build a new type, it is its
10234         own canonical type.
10235         (build_type_attribute_qual_variant): When building an attribute
10236         variant, its canonical type is the non-attribute variant. However,

10238         use structural equality checks for this type.
10239         (build_qualified_type): A qualified type is not equivalent to its
10240         unqualified variant; set the canonical type appropriately.
10241         (build_distinct_type_copy): When building a distinct type from
10242         another type, the new type is its own canonical type.

10248         also build a canonical type reference.
10249         (build_index_type): When we can't hash an index type (e.g.,
10250         because its maximum value is negative), the index type requires
10251         structural equality tests.
10252         (build_array_type): Build the canonical form of an array type.
10253         (build_function_type): Function types require structural equality,
10254         because they contain default arguments, attributes, etc.
10255         (build_method_type_directly): Ditto for method types.
10256         (build_offset_type): Build the canonical offset type.
