--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, looks like it is this part of the change:
+  if (cpu)
+    ret =3D reconcat (ret, ret, "-m", argv[0], "=3D", cpu, NULL);

-  return concat ("-m", argv[0], "=3D", cpu, NULL);


Maybe it should have been:
```
if (cpu)
  {
    if (!ret)
      ret =3D concat ("-m", argv[0], "=3D", cpu, NULL);
    else
      ret =3D reconcat (ret, ret, "-m", argv[0], "=3D", cpu, NULL);
  }
```

Can you try that?=
