I always get uneasy when I see questions about when an instruction was
*first* available. There's no assumption in Principles of Operation that
once an instruction is introduced then it will be on all following machine.
I know that in general it has worked that way in the past, but there's
always a possibility that, say, an EC-type machine will introduce some new
facility and then a later BC-type machine will be released without that
facility. I don't know why you're asking the question, but would it be
better answered by inspecting a facility bit stored by STFL(E)? If not,
well, again I apologize.

That has happened before. The MVCIN instruction was introduced
in one model, then disappeared in a subsequent model, then
returned. Of course, the whole vector instruction set has now
gone. So it goes.

Subject: Which instructions available on which machine table?

Does anybody know of a list of instructions with what model processor
they were first available on?
