22395 * c-common.c (c_common_nodes_and_builtins): Since variants of
22396 void_type_node get built before it is given a name, we need to
22397 give those variants the name, too.
22398 (complete_array_type): We need to work with the canonical main

22403 * stor-layout.c (layout_type): When we don't know the
22404 alignment of a type for which we're building an array, we end up
22405 guessing wrong, so make the type require structural equality.
22406 * tree.c (make_node_stat): When we build a new type, it is its
22407 own canonical type.
22408 (build_type_attribute_qual_variant): When building an attribute
22409 variant, its canonical type is the non-attribute variant. However,
22410 if the attributes are target-dependent and they differ, we need to
22411 use structural equality checks for this type.
22412 (build_qualified_type): A qualified type is not equivalent to its
22413 unqualified variant; set the canonical type appropriately.
22414 (build_distinct_type_copy): When building a distinct type from
22415 another type, the new type is its own canonical type.
22416 (build_variant_type_copy): When building a new type variant, we
22417 assume that it is equivalent to the original type.
22418 (build_pointer_type_for_mode): When building a pointer type, also
22419 build a canonical type pointer.
22420 (build_reference_type_for_mode): When building a reference type,
22421 also build a canonical type reference.
22422 (build_index_type): When we can't hash an index type (e.g.,
22423 because its maximum value is negative), the index type requires
22424 structural equality tests.
22425 (build_array_type): Build the canonical form of an array type.
22426 (build_function_type): Function types require structural equality,
22427 because they contain default arguments, attributes, etc.
