--- Comment #7 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- I tried the same thing with a snapshot of the 5 branch I had lying around: r225783 from 2015-07-14. I also don't see any differences in the output from the middle end, as I would expect since this bug has shown up on multiple targets. So maybe this has been fixed recently? Let me see if I can find an older snapshot.
