Sebastian, I'm not sure what your problem is. The atomics in nios2 are
implemented by __sync_* functions placed in libgcc. The built-in function
expansion inside GCC is aware of this, and __atomic_* functions get mapped to
those. Is there anything affecting your use?
libatomic is usually supported by those targets with more "rich" atomic
instructions, and nios2 in its current form is obviously not one of them.
