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.

        Indeed, Apple is following the trail of Burroughs, iAPX 432, MPX, SPARC ADI, Lisp Machines, among others.
