Abstract
Method and apparatus for creating benchmark programs for the analysis of java virtual machine implementations are implemented. Java applications and applets are compiled into an intermediate code referred to as byte code. The Java byte code forms the machine code for the Java Virtual Machine. The Java Virtual Machine running on top of a hardware platform translates the byte code into native machine code for execution on the hardware platform on which the Java Virtual Machine is running. The performance of a Java Virtual Machine is improved by the use of a so-called 'just in time' (JIT) compiler that translates commonly occurring sequences of bytes codes in the native instruction sequences which are then stored for later execution. Critical to the performance of the JIT is the ability of the JIT to optimally compile for the most commonly occurring sequences of byte codes. The method and apparatus for creating benchmark programs provides a means for performance measurements with respect to such sequences.
