Right, but seeing the speed comparison with the LLINT makes me really sad that we can't even use the baseline JIT in iOS Apps. I still have some hope that Apple works on a way to run JSC in an isolated, trusted process that is allowed to use the JIT. Otherwise the new FTL JIT doesn't get us anything in many cases.
