A new calling convention could push two return addresses for functions that return their status in EAX. On EAX=0 you take the first return, EAX != 0 you take the second.
This seems the same as passing an extra function pointer argument and calling that instead of doing a regular return. Tail-call optimization should turn the calll into a jump. Why do you think a custom ABI is necessary? -Geert
