Thanks to Maarten and Borut's help I was able to get --model-huge code
working on my system.
I did run into one issue: if my code contains a _sdcc_external_startup
routine, the stack gets blown up on return.
As far as I can tell, what happens is this:
1. We jump to _sdcc_gsinit_startup
2. _sdcc_gsinit_startup calls _sdcc_external_startup using a normal call
direct to the subroutine.
3. _sdcc_external_startup does its stuff and returns via the trampoline
(ljmp __sdcc_banked_ret).
4. _sdcc_banked_ret empties the stack and returns to the wrong place.
5. Program fails.
If I don't use an _sdcc_external_startup function, everything works.
Only when I add the external startup do I get a failure.
I was able to make the external startup work by making it a naked
function and forcing a normal return.
char _sdcc_external_startup (void) __naked {
asm
ret
end_asm;
}
Other than that, so far so good.
I am using the SDCC :
