I've been hanging around since something like 3.3.6 and rarely have I seen a newer avr-gcc produce smaller code. It happens sometimes. Is more important to generate correct code than to generate small code. I remember when avr-gcc issued two returns at the end of most (not all) routines. Pure waste. But the code ran correctly. > This is a serious bug imho and should be fixed. If its documented then its a feature, not a bug. Want smaller code? Try one of the 3.x compilers. -- David Kelly N4HHE, dke...@hiwaay.net ======================================================================== Whom computers would destroy, they must first drive mad. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
