Yup arm64e in general has pointer authentication, iOS and MacOS already implement it.

It's incredible how Apple went from a laggard in new technologies to a trailblazer.

I guess that's the power of a corporation on the scale of an 18th century trade monopoly.

Except Oracle did it first with SPARC ADI, Solaris on SPARC is one of the few UNIXes that have tamed C for couple of years now.

And actually pointer tagging architectures go all the way back to the early 1960's, with Burroughs being one of the first ones having a go at it.

It's not much of trailblazing if nobody follows on the trail.
