Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |iains at gcc dot gnu.org --- Comment #9 from Iain Sandoe <iains at gcc dot gnu.org> --- I suppose we can deduce that 0x38 == efficiency core and 0x39 is the performance one (since the counts stack up). We can figure out M1 c.f. M2/3 on the basis of the feature list - but not sure we can discriminate M2 and M3 from the feature lists alone (and M4 is currently TBD). The piece of information that would be most helpful is the "CPU family" that the Darwin kernel provides - but I have no idea how one might get that during the Linux bootstrap.
