--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Most likley exposed by r10-9646 which introduced more inlining or rather fixing an inlining issue which was broken in the GCC 10 series. This most likely was broken in GCC 9 too. The function is really just huge. I really doubt there is much to be done.
