OOE doesn't necessarily save you if you end up with a hard dependency on the value of the read (and even if it did, the little cores on ARM SoCs are in-order).

OOE doesn't necessarily save you if you end up with a hard dependency on the value of the read (and even if it did, the little cores on ARM SoCs are in-order). This is a pretty obvious candidate for macro-op fusion, but I'm not sure whether this actually happens (and if it happens on ARM little cores, etc.)
