This Dolphin article is literally about making a performant JIT run on an OS that is, among other things, strictly W^X :)

> arguments about third party browser security on iOS

Well, W^X is just one mitigation technique. But also, the "security" arguments have always been kinda dubious. I don't think there's that much difference (at least philosophically) between an interpreter bug causing arbitrary crap to happen inside your app's sandbox and a JIT bug doing the same.

As the sibling comment mentions, apparently the iOS restriction is that you cannot execute pages that have ever been marked as writable, which is much stricter than W^X.
