Cool. Just to make sure I understand this correctly, you'd
be adding support to the standalone GCJX compiler (stuff
in the "gcjx" folder) to optinally emit LLVM bytecode,
apart from the usual JVM bytecode, right?

I'm not sure if you are aware of it or not, but Chris
Lattner has proposed:

  http://gcc.gnu.org/ml/gcc/2005-11/msg00888.html

that LLVM be integrated into GCC. If this comes through,
it would be one of the most significant improvements
in GCC in recent times (apart from Tree-SSA).

Of course, it might *not* happen as well.

Irrespective of this however, I guess it would still
be very useful for GCJX to be a standalone Java
compiler and yet be able to create optimised binaries
using LLVM.

Thanks,
Ranjit.
