Thanks, Andrew.

I want to do some optimization to reduce the allocation of java objects.

The reason why I need to compile java source code to .class file is that I need
stack information to see the information about java objects
allocation. The only
way (I know) to measure results of the optimization is to use Sun Java
VM, which
can produce profiles at runtime.

I chose gcj to write plugin to do optimization. So I need its .class
files output, but
not its binary code.

If I do not get it wrong, it means that If I want to do such
optimization and measure
the outcome, I have to look for other compilers, ( since GCC plugins
won't work ) right?
