When I was patching my libgcc.a for the avrxmega7 lib, the only place that I saw, that turned off the IRQs were the epilogue/prologue. Is there some reason they don't need turned off in the other contexts? Seems like such a problem would have shown up long before now? _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-libc-dev
