[LLVMdev] Compilation problem with JIT/Interpreter

[Scott Michel]

PPE is really no different from a run-of-the-mill PowerPC (although I'm
mentally blocking on whether it's Power4, Power5 or possibly Power6). You
should be able to use LLVM on that platform. You're somewhat on your own,
though, since you'd have to actually compile it yourself.
