...no PREFETCHW for higher-level cache-lines, it is debatable what prefetch instruction should be generated when a write prefetch is requested with a locality < 3. One opinion is that the rw parameter takes precedence over locality, therefore prefetch(a, 1, 1, 1) should generate prefetchw and not prefetch2. FWIW, this is what GCC appears to do (write trumps locality.) Not sure if there is a right/wrong here; what is the preferred behavior? Thanks, - Josh
