My question is truly clear-cut: Do devices that implement certain machine code instructions (which are an extension to the ARMv8 ISA) exist? (I give instructions for how to check it.)
As per the topic page, this is a question about "computer hardware".
It was closed with the explanation that "Questions seeking product, service, or learning material recommendations are off-topic because they become outdated quickly and attract opinion-based answers.". This is absurd because I am not asking for any kind of recommendation, and any answers would not ever become outdated. Furthermore the explanation says that I should "describe [my] situation and the specific problem [I am] trying to solve" which is just patronizing, the problem I am trying to solve is find out if support for these instructions exists in real hardware.
