Hi all,
"use_service.cc" libstdc++ test does not compile for baremetal,
unfortunately AFAIK we don't have an appropriate selector to skip
these.

While the full issue is tackled would be possible to install this
patch to have it disabled on aarch64 baremetal where it is known to
be failing?
No, I don't want to paper over the problem on every individual target
where they fail.
The correct fix is either to mark the tests as requiring gthreads (as
most tests under libstdc++-v3/testsuite/30_threads/ do) or to modify
e.g. something like:
// { dg-do run }
// { dg-options "-pthread" }
// { dg-require-effective-target c++14 }
// { dg-require-effective-target pthread }
// { dg-require-gthreads "" }
Does that help, or does it still fail for other reasons?
the library code to work without mutexes for targets without thread
support.
