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

Dynamic quantatative measurements Bytecode and Stack Frame Usage by Eiffel and Java Programs in the Java Virtual Machine are made. Two Eiffel 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 Eiffel programs as well. Remarkably local_load, push_const and local_store 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
