Hmmmm. I wonder which OS will support in-kernel JIT for JavaScript first. :v (/s ... I hope??)

- vlovich123 5y agoWhy would it need to be in-kernel? What advantage does that serve? For what it’s worth there’s JavaScriptCore (at least for mobile) which is the only way to do JIT on iOS. It’s constantly criticized as being slower than competing JavaScript JITs while Apple counters that it’s an important security barrier.
- skavi 5y agoIn kernel eliminates context switching overhead. Theoretically a perfect JIT doesn’t need hardware security. Also, JSC has been faster on Mac than V8 until a few days ago.
- vlovich123 5y agoWhat context switching overhead is eliminated? This makes no sense.
