libstdc++ before gcc r244057 expected that libc provided __cxa_thread_atexit_impl, and libstdc++ implemented __cxa_thread_atexit, by forwarding the calls to _impl. Mentioned gcc revision checks for __cxa_thread_atexit in libc and does not provide the symbol from libstdc++ if found. This change helps older gcc, in particular, all released versions which implement thread_local, by consolidating the implementation into libc. For that versions, if configured with the current libc, the __cxa_thread_atexit is exported from libstdc++ as a trivial wrapper around libc::__cxa_thread_atexit_impl. The __cxa_thread_atexit implementation is put into separate source file to allow for static linking with older libstdc++.a. gcc bugzilla: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78968 Reported by: Hannes Hauswedell <h2+fbsdports@fsfe.org> PR: 215709 Sponsored by: The FreeBSD Foundation MFC after: 2 weeks |
