--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I still don't see why a compact unwind format can't handle this. Plus I am not sure the ABI will/can be changed to support a new unwind format. It would require a flag day which which will not happen any time soon. And then all distros need to support it all the same time etc.
