Try the inline assembler from the Linux/x86_64 port (translated to S10 syntax).

/* from RTESys_MemoryBarrier.h */
#elif defined(LINUX) && defined(X86_64)

/* from #include <asm-x86_64/system.h> mb(),rmb(),wmb() definitions */

# define RTESys_MemoryBarrier()      __asm__ __volatile__("mfence":::"memory")
# define RTESys_ReadMemoryBarrier()  __asm__ __volatile__("lfence":::"memory")
# define RTESys_WriteMemoryBarrier() __asm__ __volatile__("sfence":::"memory")

The developer who did the Linux/x86_64 port has vague memories that there were 
also problems using a dummy implementation.
