--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
You could as well step through the driver-i386.c and cpuinfo.h code in the
debugger.
>>From the info you've provided, seems you have __cpu_family 6 and __cpu_model
0x9e, so get_intel_cpu should reach:
    case 0x4e:
    case 0x5e:
      /* Skylake.  */
    case 0x8e:
    case 0x9e:
      /* Kaby Lake.  */
    case 0xa5:
    case 0xa6:
      /* Comet Lake.  */
      cpu =3D "skylake";
      CHECK___builtin_cpu_is ("corei7");
      CHECK___builtin_cpu_is ("skylake");
      cpu_model->__cpu_type =3D INTEL_COREI7;
      cpu_model->__cpu_subtype =3D INTEL_COREI7_SKYLAKE;
      break;=
