newbie question: porting to another compiler

[Steven Carroll <scarroll at csrd dot uiuc dot edu>]

Hi,
I'm new to using GCJ.  I'm interested in using your implementation of
the java core libraries
with the compiler we are developing.  Our compiler, PROMIS (our
grievously out of date webpage is at www.csrd.uiuc.edu/promis), has a
front end for reading in java bytecode and doing a number of
optimizations on those codes that i've written.
I currently have a very simple runtime system that implements the bare
minimum necessary to run SPECVM's compress, but in the long run, I'd
like to be able to use something a little more robust.

From browsing through the source code, it seems like there is a strong
coupling between the class library implementation and the compiler
code.  I am wondering if anyone has had any success in using these class
library implementations outside of GCC or GCC variants?  Is there any
documentation on this sort of application?  I've not had much luck in
searching the archives here for that purpose.

thanks alot,
