Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to work| |15.0 --- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Fixed on the trunk, I suspect r15-917-gc9842f99042454 fixed it. That revision is explictly fixing `POLY_INT_CST [16, 16] /[ex] 16` case too. I think we should just add the testcase and close it as fixed.
