Not quite sure what you mean, but stuff like this (from the avr gcc
manual):

---------------------------------
#include <avr/interrupt.h>

ISR(ADC_vect)
{
     // user code here
}
----------------------------------

Also, it would be nice to be able to refer both to the program memory
and the data memory (AVR is a Harvard architecture) in a convenient
way.

I'm not sure how much of this could already be handled with the
existing machinery.
