--- Comment #20 from Sam James <sjames at gcc dot gnu.org> --- When I looked at it, I think I got it to apply to 13 with no hassle and it seemed to work okay, but I didn't test it that hard. It's a considerable win so even if not backported upstream, if you think it's safe enough, let us know if it's ok for us to do it downstream in Gentoo. (That could also serve as a form of testing to do it upstream on releases/gcc-13 if desired.)
