--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note, trunk handles it fine again starting with r11-4755-g22984f3f090921b5ac80ec0057f6754ec458e97e So I guess we should just add the testcase (perhaps use a parameter instead of volatile etc.) and close, ranger is not backportable and even smaller VRP improvements might be too risky.
