Comparison of Bytecode and Stack Frame Usage by Eiffel and Java Programs in the Java Virtual Machine

Dynamic quantitative measurements of Bytecode and Stack Frame Usage by Eiel and Java Programs in the Java Virtual Machine are made. Two Eiel programs are dynamically analysed while executing on the JVM, and the results compared with those from the Java Programs. The aim is to examine whether properties like instruction usage and stack frame size are properties of the Java programming language itself or are exhibited by Eiel programs as well. Investigations analyse how the dierent assertion checking and optimizations possible using the SmallEiel compiler aect bytecode and stack frame usage. Remarkably local load, push const and local store instruction categories always account for very close to 40% of instructions executed, a property of the Java Virtual Machine irrespective of the programming language, compiler or compiler optimizations used. Java programs executed 75% of their bytecodes within the API suggesting a way to improve the speed of Java programs w..
