I havn't define ACCUMULATE_OUTGOING_ARGS because AVR have a very small displacement for memory addressing (63 bytes) and I think that better to have a minimal possible frame size (because of difficult addressing of a local variables outside of fp+63 boundary). Generally, ACCUMULATE_OUTGOING_ARGS enlarge the frame size. Denis. PS: I didn't try ACCUMULATE_OUTGOING_ARGS for AVR. May be results will be better than I think.
