Correctness-wise, the patch does not trigger any faults on the benchmark that I'm using, so that's good. Performance-wise, I didn't see any significant difference. It may be that XLP's cache doesn't benefit from using prepare-for-store hints. In any case, the patch doesn't regress performance, so I'm OK with it.
Steve, did you run normal glibc testsuite on this patch with no failures?
Thanks,
