Of course V8 supports asm.js. asm.js is just JavaScript. Okay, I know what you mean, but still why wouldn't it be a fair comparison? V8 is free to "support" as

  How about "it's not a comparison that matters"? Nobody will see any benefits from JSCore being "faster than V8 on asm.js". In fact, if JSC is slower on non asm.js code, the comparison would also be extremely misleading too, because 99.9999% of web code is NOT asm.js. At the moment it's like saying "JSC is faster than v8 on a synthetic benchmark almost nobody really uses in the actual world, and v8 hasn't bothered optimizing for".

    Obviously, people using asm.js will benefit from JavaScriptCore being faster than V8 on asm.js. Whether it matters is an interesting question, but V8 developers seem to disagree with you, because they included asm.js benchmark in Octane benchmark suite, which V8 developers use to tune V8.

      >Obviously, people using asm.js will benefit from JavaScriptCore being faster than V8 on asm.js Also obviously I covered that, when I wrote "99.9999% of web code is NOT asm.js". So who are these "people"? All 10 of them? >Whether it matters is an interesting question, but V8 developers seem to disagree with you, because they included asm.js benchmark in Octane benchmark suite, which V8 developers use to tune V8. If anything, it shows that they agree with me. See how I compared asm.js to a "synthetic benchmark" in my comment?
