e platform on 
			which this feature is supported is the Itanium2. In fact, event counting on 
			Itanium2 can be qualified by a number of conditioners, including instruction 
			address, opcode matching, and data address. We have implemented a generalized 
			PAPI interface for data structure and instruction range performance 
			instrumentation, also referred to as data and instruction range specification, 
			and applied that interface to the specific instance of the Itanium2 platform to 
			demonstrate
