The Stack: which comes first?
-
No one uses frame pointers in z80 code anyway - at least not AFAIK. You rarely have any spare 16bit registers - especially not if you spilled some variables to the stack already. Maybe IX, but it's a PITA to use. And you can't do a 16bit indirect load. And there is no base+offset addressing mode except for the index registers, but as I said, they're a PITA to use. They (index registers) also bloat your code. I've seen them in crappy compiler output though..

Yeah - the IAR C compiler makes heavy use of them. POS program, it was easier and quicker to code it in Z80 assembler most of the time.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

The stack is a bi-directional cluster f**k, or to put it another way sometimes you get the bear and sometimes the bear s&*ts on you. :) Good luck

Now if you was obama you would just write an executive order and be done with it instead of actually going through the legitimate process.
