Subject: [PATCH] testsuite: Require thread-fence for 29_atomics/atomic_flag/cons/value_init.cc
Date: Tue, 26 Sep 2023 16:40:58 +0200 [thread overview]
Message-ID: <20230926144058.874C82042E@pchp3.se.axis.com> (raw)
Ok to commit?

A recent patch made __atomic_test_and_set no longer fall
back to emitting non-atomic code, but instead will then emit
a call to __atomic_test_and_set, thereby exposing the need
to gate also this test on support for atomics, similar to
r14-3980-g62b29347c38394.
libstdc++-v3:
* testsuite/29_atomics/atomic_flag/cons/value_init.cc: Add
dg-require-thread-fence.
