From: Jonathan Wakely <redi@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r12-4075] libstdc++: Remove unary_function base classes from std::thread tests Date: Fri, 1 Oct 2021 19:39:30 +0000 (GMT) [thread overview] Message-ID: <20211001193930.C86E23857821@sourceware.org> (raw) https://gcc.gnu.org/g:9b790acc2207d69b4ebc0f4addd34a0aa32ec6cf commit r12-4075-g9b790acc2207d69b4ebc0f4addd34a0aa32ec6cf Author: Jonathan Wakely <jwakely@redhat.com> Date: Mon May 24 18:32:22 2021 +0100 libstdc++: Remove unary_function base classes from std::thread tests std::thread does not care if a function object is adaptable, so there is no need to derive from the deprecated std::unary_function class in these tests. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: * testsuite/30_threads/thread/cons/3.cc: Remove derivation from std::unary_function. * testsuite/30_threads/thread/cons/4.cc: Likewise. * testsuite/30_threads/thread/cons/5.cc: Likewise.
