Is there really no way to determine the location of an assembler routine during runtime? My (wild) idea is to mark the beginning of a routine with a characteristic sequence of (redundant) instructions, e.g. sei sei sei. Then one could use another routine to search for this sequence (using lpm or elpm?). Would this be possible? But I don't see how one could then change the interrupt vectors. Do you? Any other ideas?
