#include <cafe/os.h> void OSCoherencyBarrier(void);
Executes a PowerPC
SYNC instruction, forcing stores on the existing processor core to become coherent prior to resuming execution on the current processor core.
SYNC instruction on Espresso differs from the standard PowerPC architecture, whereas stores become coherent in the CPU domain, but
SYNC does not wait until stores complete to memory.
