Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The HW sqrt certainly handles NAN input by returning NAN output, the question is if it is required to set some errno in that case as well or not. One would need to check what different libcs do in that case.
