--- Comment #19 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Sorry, my fault, forgot about -da, can you repeat with that option as well? Your optimized dump is identical to my, so if there is a difference (and there must be, because the function in question isn't called for me), it must be during the RTL passes.
