--- Comment #25 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
Yes, that test in check_effective_target_shared actually works with C, but not
with C++, because:

Undefined symbols for architecture arm64:
  "__Z3foov", referenced from:
      __Z3bazv in ccCj5plO.o

Why have we not seen it before? Because most of the use of that check is in {
dg-require-effective-target shared } so we're effectively skipping tests, and
that is silent.

As far as I can tell, your addition is the first time { target shared } is used
as a conditional in something like { dg-additional-options } in the C++
testsuite.

Thanks for helping me figuring it out, that's definitely at least a darwin
issue, which I'll take care of.
