[ih] OOT: What is a stack?

[Rahmat M. Samik-Ibrahim]

Hello:

I have no idea where to follow up this issue; hopefully this
list is the best fit.

I am not familiar with SPARC, cmiiw, it uses 32 multipurpose
registers with a sliding window. Therefore, what is exactly
"prevent execution of code on the stack" ?

Speaking of stack history, how many processors that actually
call one of its register as a "stack pointer"? Intel 8XXX,
Zilog, what else?

How about PDP-11, does R5 count as a stack pointer?
How about HP-1000, where a return address was stored
in the front of a subroutine (Jump save address)?

regards,
