Oh noooo, that's crap :-( Can't we just have an command line option to force the use of the H/W multiplier ? How should we do to submit this as a top-priority goal for the next release of avr-gcc ? Is anyone in the avr-gcc team on this list ?? This needs to be addressed ! :-/ -- Vince _______________________________________________ AVR-GCC-list mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
