Details
When comparing octane-regexp on linux/windows it is visible that readBarrier is taking more time on windows. It takes 54ms of the time, while on linux only 18ms.
I'm esp. talking about:
js::InternalGCMethods<class js::SavedFrame *>::readBarrier
(which in linux has js::InternalGCMethods<class js::JSObject *>::readBarrier as signature)
I'm still not entirely sure what the difference exactly is though. But on both platforms
shadowZone->needsIncrementalBarrier()
JS::GCThingIsMarkedGray(thing)
is false. So we this is actually a nop.
