813 //
814 // In addition to the above types, this list is required to enumerate
815 // the JNI's java types, which are used to indicate the size of Java
816 // fields in this VM to the SA. Further, oop types are currently
817 // distinguished by name (i.e., ends with "oop") over in the SA.
818 //
819 // The declare_toplevel_type macro should be used to declare types
820 // which do not have a superclass.
821 //
822 // The declare_integer_type and declare_unsigned_integer_type macros
823 // are required in order to properly identify C integer types over in
824 // the SA. They should be used for any type which is otherwise opaque
825 // and which it is necessary to coerce into an integer value. This
826 // includes, for example, the type uintptr_t. Note that while they
827 // will properly identify the type's size regardless of the platform,
828 // since it is does not seem possible to deduce or check signedness at
829 // compile time using the pointer comparison tricks, it is currently
830 // required that the given types have the same signedness across all
831 // platforms.
