It's really unpleasant that we keep getting new attributes that we seemingly are encouraged to use and get sent patches for it. And then we learn a little later that that stuff isn't ready yet. It's annoying. I know it isn't your fault but it would be wise to be a little more careful. IOW, unless both clang and gcc do support that thing appropriately don't send patches to various subsystems for this. In any case, this is now fixed. I pulled an updated version from David.
