816 //
817 // In addition to the above types, this list is required to enumerate

819 // fields in this VM to the SA. Further, oop types are currently
820 // distinguished by name (i.e., ends with "oop") over in the SA.
821 //
822 // The declare_toplevel_type macro should be used to declare types
823 // which do not have a superclass.
824 //
825 // The declare_integer_type and declare_unsigned_integer_type macros
826 // are required in order to properly identify C integer types over in
827 // the SA. They should be used for any type which is otherwise opaque
828 // and which it is necessary to coerce into an integer value. This
829 // includes, for example, the type uintptr_t. Note that while they
830 // will properly identify the type's size regardless of the platform,
831 // since it is does not seem possible to deduce or check signedness at
832 // compile time using the pointer comparison tricks, it is currently
833 // required that the given types have the same signedness across all
834 // platforms.
