I have tried tried this patch together with the latest patch for/of PR97000
for tree-cfgcleanup.c on tree-cfgcleanup.c:

Now, I only see the expected failures and the compare_and_swap issue in
the testsuite is gone (libgomp.c-c++-common/reduction-17.c)

:-)

(Jakub's atomic test fails with a link error:
"__atomic_compare_exchange_16" (the build I have has
--disable-libatomic, hence, I cannot check this with
-foffload=-latomic right now; something to check later.)

Thanks,

Tobias
