Re: Rep:Re: [f-cpu] Stack handling
Have you ever written a compiler ?
A stack is the most simple and clean solution to handle a lot of thing.
We have a lot of register so most compiler simulate the first stack
push/pop with reg but when the stack grow we need a real stack handling.
If we haven't stack we must reinvent the weel or back 50 years ago in
compiler theorie.
The debat about the number of stack is another thing, I think we need
some instruction for stack (pre-dec) on all register so we can have all
stack we need.
