In the C forum, we had this discussion:
How to calculate the Stack Size?
In it, my code was slated because it assumes that there is a stack. Of course, C being a function-based language, there needs to be SOME FORM OF stack, even if the stack is managed by software (such as the Deep Blue C for 6502 - since 6502 doesn't have a processor stack that is worth anything, it's 256 bytes long - hardly enough for passing arguments and calling functions in any reasonable C program). .
But can someone tell me if there is any machines in current production use (not counting machines kept alive in a museum somewhere) that doesn't have a conventional stack - besides pointing out that some machines have TWO stacks [e.g. 29K that has a "register" stack and a "memory" stack].
I'm just curious as to what machines (today) would not have a stack in a meaningful way.
