Great work, James!

This is from luajit's code:

lj_asm.c

/* Flush instruction cache. */
static void asm_cache_flush(MCode *start, MCode *end)
{
  VG_INVALIDATE(start, (char *)end-(char *)start);
#if LJ_TARGET_X86ORX64
  UNUSED(start); UNUSED(end);
#elif LJ_TARGET_OSX
  sys_icache_invalidate(start, end-start);
#elif defined(__GNUC__)
  __clear_cache(start, end);
#else
#error "Missing builtin to flush instruction cache"
#endif
}
