Hi, in my avr-libc there is a bug in avr/cpufunc.h in the memory barrier macro. It is defined as
#define _MemoryBarrier() __asm__ __volatile__(:::"memory") but should be: #define _MemoryBarrier() __asm__ __volatile__("" :::"memory") Best regards, Martin Laabs _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
