According to a talk I saw on the web a few years ago
now, by one of
the guys in charge of P3 (or P4), people still ask "can I have
such-and-such" an instruction!
The nerve of them! Expecting what people want
to actually matter to
the processor designers!
Now, now. If you ask a hundred different TLAs what they
most need
added to the ISA to best help them infringe people's liberties you'll
get one hundred different answers :-)
Certainly. But you can't learn about the three that are wanted by a
nontrivial fraction of the userbase without listening to them all.
I didn't say they had to actually implement all - or even any - of
those suggestions. But not even being interested in the suggestions is
just plain lunacy.
Seriously, if you need pop(N) or whatever, you can
implement it today
and in a year (or two) from now you'll be running as fast as you
thought you would have been with pop(N).
And you have the nerve to preface that with "seriously"?! You could
say the same about pretty much any software thing - simulate it and let
Moore's Law speed it up. Some of us aren't willing to wait a year (or
two) per feature to run it at a decent speed.
