Patrick Palka f0d8d001d9 libstdc++: Non-triv-copyable extra args aren't simple [PR100940] ... This force-enables perfect forwarding call wrapper semantics whenever the extra arguments of a partially applied range adaptor aren't all trivially copyable, so as to avoid incurring unnecessary copies of potentially expensive-to-copy objects (such as std::function objects) when invoking the adaptor. PR libstdc++/100940 libstdc++-v3/ChangeLog: * include/std/ranges (__adaptor::_Partial): For the "simple" forwarding partial specializations, also require that the extra arguments are trivially copyable. * testsuite/std/ranges/adaptors/100577.cc (test04): New test.
