Keep in mind that SUBI will set the carry flag. INC does not set the carry flag. I don't know if that is important in this particular case, but it might be useful info so you don't introduce regressions. Speaking of which, if you develop a patch, you need to be sure to run the GCC Regression Test Suite. > > PS: is gccint.info a typo? gccint.info is the GCC Internals documentation in the 'info' format. _______________________________________________ AVR-GCC-list mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
