--- Comment #7 from Matthew Malcomson <matmal01 at gcc dot gnu.org> ---
Hi there,

I didn't check all the new tests that Christophe mentioned, but all those I
checked had `dg-require-effective-target hwaddress_exec` in them.

The test that determines that effective target should only pass with a modern
enough kernel (one that supports passing tagged pointers to its syscalls).
It is still failing on my native AArch64 machine.

For anyone that is seeing them -- what kernel version are you running?
If your kernel has not changed could you manually run the check and see if it
passes and why?

I've unfortunately lost my testing environment.  I'm working on getting it back
but will be a while before I can see if I can reproduce the failures on a
machine with the required kernel.
