Perhaps HLE_ACQUIRE / HLE_RELEASE should be something like HLE_START /

overloading ACQUIRE/RELEASE and thus should make it clearer that you
still need to specify a memory order.
Does it make any sense to simply predefine the possible valid
combinations with the HLE bit already set? it at least removes any
possible invalid combinations and forces the programmer to consciously
choose their memory model.
or whatever happens to be valid... Doesn't really scale to adding more
new bits later, but perhaps that doesn't matter.
Just a thought.
