--- Comment #2 from Peter Bergner <bergner at gcc dot gnu.org> --- None of my recent IRA or LRA patches were back ported and I wasn't planning on it, given the fallout they caused. Do we know for sure this doesn't work on GCC 8? Given when Alexander opened this bug, I'm guessing he just got caught in the middle of all of my changes. If this works on GCC 8, we can probably just close that as already fixed.
