Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think Darwin doesn't have it (though I have no access to it, so can't check), googling around shows that sysctl -a | grep machdep.cpu or MacCPUID utility might provide the information we need.
