- There's some research being done into stack processors with no conditional
- branch instructions. Instead, there will be conditional calls (and maybe
- conditional returns?). These operations can be fast (one or zero clock
- cycles?) on a stack machine.
-
- I'm not sure if replacing branches with calls would reduce the problem of
- conditional anything, as far as pipelining is concerned, but I suppose it has
- possibilities.
