[rvm-research] Jikes Control Flow: Execution of Java Program

[vishal j. <vis...@gm...>]

Hi,

I am working on a Jikes RVM project and is trying to understand the control
flow of execution of Java program running on RVM.

The BaseLine compiler Compiles the method(by reading bytecode) and stores
them in an array "machineCodes" which has the machine code translation the
bytecode of Java program which I run.
I wanted to know where exactly are the machine codes from this array
executed finally ?

Also, when printing all the machine codes present in this array, a lot of
code does not correspond to the Java program I am running. I guess this
corresponds to some part of Jikes RVM itself being compiled by Baseline
compiler. Am I right? And if so, how do I distinguish the machine code of
my Java program from the machine code of Jikes RVM itself.

I also want to establish a communication channel(example a Pipe) between my
Java program and Jikes RVM. This has to be done to find the trace of Java
program. All the instructions of Java program will write information in
this channel which could be read by Jikes RVM. How should I implement this?

Thanks and Regards
