Subject: [committed] testsuite: Fix warning regression due to std::string changes [PR106795]
Date: Wed, 31 Aug 2022 21:10:50 +0100	[thread overview]
Message-ID: <20220831201050.159907-1-jwakely@redhat.com> (raw)
In-Reply-To: <20220826201638.214427-1-jwakely@redhat.com>

I missed this testsuite fix in the libstdc++ commit.

Tested x86_64-linux, pushed to trunk.

std::string now has [[nodiscard]] attributes on most members, causing
-Wunused-result warnings for this test.

gcc/testsuite/ChangeLog:

	PR testsuite/106795
	* g++.dg/tree-ssa/empty-loop.C: Use -Wno-unused-result.
