Alexandre Oliva 3d0f3382fa libsupc++: try cxa_thread_atexit_impl at runtime ... g++.dg/tls/thread_local-order2.C fails when the toolchain is built for a platform that lacks __cxa_thread_atexit_impl, even if the program is built and run using that toolchain on a (later) platform that offers __cxa_thread_atexit_impl. This patch adds runtime testing for __cxa_thread_atexit_impl on select platforms (GNU variants, for starters) that support weak symbols. for libstdc++-v3/ChangeLog PR libstdc++/112858 * config/os/gnu-linux/os_defines.h (_GLIBCXX_MAY_HAVE___CXA_THREAD_ATEXIT_IMPL): Define. * libsupc++/atexit_thread.cc [__GXX_WEAK__ && _GLIBCXX_MAY_HAVE___CXA_THREAD_ATEXIT_IMPL] (__cxa_thread_atexit): Add dynamic detection of __cxa_thread_atexit_impl.		2023-12-07 00:38:14 -03:00
