Um, what CISC ISAs do you think are more complicated than x86?


I'm going from John Mashey's famous Usenet post on the issue.

https://userpages.umbc.edu/~vijay/mashey.on.risc.html

So that would be things like Vax that not only have load-store opps, they also have things like indirect loads and stores in a single operation.


S/360 and it’s successors


S/360 is also a relatively simple CISC.

The more complex ones (many mem-mem instructions with fancy addressing modes) are VAX, 68020, NS32000.
