When I try to rebuild GCC 10.3 or 10.2, they end up having the same problem.
Also, when I enable bootstrapping, bootstrapping fails with differences in many
files. Given that this used to work on a

The failing GCC 11.1.0 is built by Apple Clang 12.0.5 via Spack. Looking at
debug output, I see that Spack inserts a "-march=skylake" command line option.
(I was not aware of this before.) It does so by

Yes, GCC 10.3 (built via MacPorts) still works. The sample program reports a
Skylake CPU with both compilers.

I also tried on a xeon w machine with darwin19 (macOS 10.15), where it detects
skylake-avx512 (which is a reasonable description, although possibly
cascadelake would be slightly more accurate)

You could as well step through the driver-i386.c and cpuinfo.h code in the
debugger.

This is my hardware configuration:
$ sysctl -a | grep machdep.cpu
machdep.cpu.address_bits.physical: 39

machdep.cpu.arch_perf.events: 0

And it works fine for me on skylake-avx512 too.
