Subject: libstdc++: Remove dg-options "-std=gnu++20" from std::chrono tests
X-Git-Tag: basepoints/gcc-15~6085
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41cd9d4dfe9b485d464e353efd5f32367946e4e1;p=thirdparty%2Fgcc.git

libstdc++: Remove dg-options "-std=gnu++20" from std::chrono tests

The testsuite will automatically select C++20 for these tests now, and
removing the hardcoded -std option allows them to be tested for C++23
and C++26 as well.

libstdc++-v3/ChangeLog:
