I would use something like simics if you can.  If you use an alpha
simulator you will either need to do some work on the backend or use
an older version of llvm.  If you can do your work with a different
cpu, then a simulator for x86, powerpc, or arm would probably be your
best bet for good performance (and most mature backends) from llvm.
