Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords|missed-optimization | --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I think this memset is only partial dead and not fully dead. What I mean is the string p->n is smaller than 254, then the memset is still not dead.
