[PATCH] D40863: [AArch64][Darwin] Implement stack probing for static and dynamic stack objects

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

It would be helpful to describe somewhere what exactly stack probing is. Maybe add more comments to emitStackProbe() and the commit message.

Is it one of those situations where you have to touch the OS pages backing stack memory one after the other (instead of accidentally jumping across pages for big arrays)?
