25296 * c-common.c (c_common_nodes_and_builtins): Since variants of
25297 void_type_node get built before it is given a name, we need to
25298 give those variants the name, too.

25306 guessing wrong, so make the type require structural equality.
25307 * tree.c (make_node_stat): When we build a new type, it is its
25308 own canonical type.
25309 (build_type_attribute_qual_variant): When building an attribute
25310 variant, its canonical type is the non-attribute variant. However,
25311 if the attributes are target-dependent and they differ, we need to
25312 use structural equality checks for this type.
25313 (build_qualified_type): A qualified type is not equivalent to its
25314 unqualified variant; set the canonical type appropriately.
25315 (build_distinct_type_copy): When building a distinct type from
25316 another type, the new type is its own canonical type.
25317 (build_variant_type_copy): When building a new type variant, we
25318 assume that it is equivalent to the original type.
25319 (build_pointer_type_for_mode): When building a pointer type, also
25320 build a canonical type pointer.
25321 (build_reference_type_for_mode): When building a reference type,
25322 also build a canonical type reference.
25323 (build_index_type): When we can't hash an index type (e.g.,
25324 because its maximum value is negative), the index type requires
25325 structural equality tests.
25326 (build_array_type): Build the canonical form of an array type.
25327 (build_function_type): Function types require structural equality,
25328 because they contain default arguments, attributes, etc.
25329 (build_method_type_directly): Ditto for method types.
25330 (build_offset_type): Build the canonical offset type.
25331 (build_complex_type): Build the canonical vector type.
