The wrong cpuid reporting sure.  What I meant was that there are still CPUs
that claim to be Haswell or Skylake, yet they don't support the ISAs GCC
includes under the corresponding -march= option. Looking in detail on the
Skylake based Pentium or Celeron, they don't even have AVX, so clearly users
just must not consider them anything more than a mere westmere or something
similar.
