Here is a list of known AVR GCC bug reports: <http://www.nongnu.org/avr-libc/bugs.html> Please note the ones marked as "missed optimization". See if your bug fits one of those. If not, then please submit a bug report to the GCC project. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
