2000-04-08 Anthony Green <green@redhat.com> * java/lang/natObject.cc (_Jv_MonitorEnter): Only perform null check when we have to. * gcj/array.h: Mark elements(JArray<T>& x) and elements(JArray<T>* x) as `inline'. * java/util/StringTokenizer.java: Minor optimization. Eliminates one method call. * java/util/Vector.java (VectorEnumeration.nextElement): Manually inline hasMoreElements. From-SVN: r33033
