--- Comment #29 from Jeffrey A. Law <law at redhat dot com> --- No decision has been made on whether or not to include either or both approaches to fixing this BZ into GCC 5. It's still under evaluation/review. I think for GCC 6 it's highly likely we'll have both since they're both independently good things to do.
