9335 * c-common.c (c_common_nodes_and_builtins): Since variants of
9336 void_type_node get built before it is given a name, we need to
9337 give those variants the name, too.
9338 (complete_array_type): We need to work with the canonical main
9339 type of the array, from which we will build the qualified version.

9343 * stor-layout.c (layout_type): When we don't know the
9344 alignment of a type for which we're building an array, we end up
9345 guessing wrong, so make the type require structural equality.

9348 (build_type_attribute_qual_variant): When building an attribute
9349 variant, its canonical type is the non-attribute variant. However,
9350 if the attributes are target-dependent and they differ, we need to
9351 use structural equality checks for this type.
9352 (build_qualified_type): A qualified type is not equivalent to its
9353 unqualified variant; set the canonical type appropriately.
9354 (build_distinct_type_copy): When building a distinct type from
9355 another type, the new type is its own canonical type.
9356 (build_variant_type_copy): When building a new type variant, we
9357 assume that it is equivalent to the original type.
9358 (build_pointer_type_for_mode): When building a pointer type, also
9359 build a canonical type pointer.
9360 (build_reference_type_for_mode): When building a reference type,
9361 also build a canonical type reference.
9362 (build_index_type): When we can't hash an index type (e.g.,
9363 because its maximum value is negative), the index type requires
9364 structural equality tests.
9365 (build_array_type): Build the canonical form of an array type.
9366 (build_function_type): Function types require structural equality,
9367 because they contain default arguments, attributes, etc.
9368 (build_method_type_directly): Ditto for method types.
9369 (build_offset_type): Build the canonical offset type.
9370 (build_complex_type): Build the canonical vector type.
