natObject.cc (_Jv_MonitorEnter): Only perform null check when we have to.
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.
