vxworks' libatomic comes from its libc, and it's missing
__atomic_feraiseexcept. ARM and AArch64 ports call it implicitly in
c11-atomic-exec-[23].c, so these tests fail.
No exceptions are expected to be raised by these tests, so I'm working
around and silencing the failures by defining the missing function
when compiling for the affected target.
(We're considering changing libatomic so that, on VxWorks, it adds the
symbols that are missing from libc, without overriding them, but for now
this silences a couple of failures.)
Regstrapped on x86_64-linux-gnu. Also tested with gcc-14 on aarch64-,
arm-, x86-, and x86_64-vxworks7r2. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.dg/atomic/c11-atomic-exec-2.c [__VXWORKS__]
(__atomic_feraiseexcept): Define.
* gcc.dg/atomic/c11-atomic-exec-3.c: Likewise.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
