If I understand correctly, my changes in http://gcc.gnu.org/viewcvs/trunk/gcc/config/avr/libgcc.S?r1=179760&r2=179759&pathrev=179760 are no good and I should rework the patch to use EI*, and instead of PUSH zero_reg there should either a push of EIND or, if no RET is used to indirect jump, EIJMP instead if IJMP?
