Any useful way (amd64) to effect a transfer like this? pc <-- (sp) [Note the absense of auto-decrement]

Question

That's it. Seems to be specifically absent.

Just read ('red') the instruction set, I don't see an obvious way to do this?

Looking for a way to get the same result, shorter is better of course. (Have not looked at ARm yet, but in case you happen to already know the answer, ...)
