G++ implements P1972R2 since r11-1597-0ca22d027ecc and so we no longer need the P0608R3 special case to prevent narrowing conversions to bool. Since non-GNU compilers don't necessarily implment P1972R2 yet, this may cause a regression for those compilers. There is no feature-test macro we can use to detect it though, so we'll have to live with it. libstdc++-v3/ChangeLog: PR libstdc++/95832 * include/std/variant (__detail::__variant::_Build_FUN): Remove partial specialization to prevent narrowing conversions to bool. * testsuite/20_util/variant/compile.cc: Test non-narrowing conversions to bool. * testsuite/20_util/variant/run.cc: Likewise. |
