The current version of the ARM ARM says "unpredictable". But this general definition of "unpredictable" does not allow it to deadlock (hardware) or have security implications. It is however allowed to corrupt data.
Not allowed to have security implications, but is allowed to corrupt data.
By security I was referring to TrustZone extensions. IOW, unpredictable in normal (non-secure) world should not cause data corruption in the secure world.
That definition is rather useless for operating systems that don't use Trustzone then, right?
