What do you mean 'forbid' it?
Isn't the HLE bit suppose to be a hint anyway? Saying if the hardware supports
it, use it on this atomic instruction... Its not incorrect to ignore it, and
some targets simply don't support it. so its ignored.
I would expect that when we have to drop back to a compare-exchange loop we're
no longer going to really care?
