Subject: libstdc++: Correct requirements for atomic/cons/zero_padding.cc tests [PR124124].
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=060d7c2a9c1fe16d23d98a74287fdb7c73ddb784;p=thirdparty%2Fgcc.git

libstdc++: Correct requirements for atomic/cons/zero_padding.cc tests [PR124124].

This test uses atomic<T>::compare_exchange_strong and thus may require
libatomic and atomic-cmpxchg-word. The requirement on thread-fence and
non_pch were superfulous.

	PR libstdc++/124124

libstdc++-v3/ChangeLog:

	* testsuite/29_atomics/atomic/cons/zero_padding.cc: Adjust
	dg-require.
