Subject: [committed] libstdc++: Suppress -Waddress warning in tzdb.cc [PR108228]
Date: Fri,  6 Jan 2023 21:21:35 +0000	[thread overview]
Message-ID: <20230106212135.397113-1-jwakely@redhat.com> (raw)

Tested x86_64-linux and powerpc-aix. Pushed to trunk.

-- >8 --

For some tarets the weak symbol is always defined, so we get a warning
that its address is never null. The warning isn't useful in this case,
so suppress it.

libstdc++-v3/ChangeLog:

	PR libstdc++/108228
	* src/c++20/tzdb.cc (zoneinfo_dir): Add diagnostic pragma.
