I'm so glad to see that Webkit is not dead after the Blink fork. I still use Safari as my main browser, but its developer tools and optimizing compiler lag behind.
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.
