--- 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.
