Perhaps you want to replace the “long” by `64-bit' to be more exact? (Though AVR-GCC's 64-bit support, while working, is not its brightest side, arguably.)
The 64-bit integer support has been improved with the avr-gcc 4.7 release series, see the 4.7 release notes http://gcc.gnu.org/gcc-4.7/changes.html#avr For technical details cf. http://gcc.gnu.org/viewcvs?view=revision&revision=182794 http://gcc.gnu.org/viewcvs?view=revision&revision=182160 http://gcc.gnu.org/viewcvs?view=revision&revision=181551 This leads to the paradoxical situation that for specific values the 64-bit division routine works faster than the 32-bit division routine for these values. _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
