Well currently our project is made up of the following.  A SUIF Frontend + 
SUIF-MACH backend which generates VHDL.  All the optimization passes currently 
reside on the SUIF frontend, but due to it's non-maintenance, and problems with 
moving to a newer OS version, we wanted to move that over to LLVM, but still 
keep on using the MACH-SUIF backend.  We want to compare how much better LLVM is 
to SUIF (a prototype of course).   If we succeed in that, then I believe that we 
may merge the work from MACH-SUIF into LLVM.
