2021-11-04libstdc++: Deprecate std::unexpected and handler functionsJonathan Wakely1-0/+1
These functions have been deprecated since C++11, and were removed in C++17. The proposal P0323 wants to reuse the name std::unexpected for a class template, so we will need to stop defining the current function for C++23 anyway. This marks them as deprecated for C++11 and up, to warn users they won't continue to be available. It disables them for C++17 and up, unless the _GLIBCXX_USE_DEPRECATED macro is defined. The <unwind-cxx.h> header uses std::unexpected_handler in the public API, but since that type is the same as std::terminate_handler we can just use that instead, to avoid warnings about it being deprecated. libstdc++-v3/ChangeLog: * doc/xml/manual/evolution.xml: Document deprecations. * doc/html/*: Regenerate. * libsupc++/exception (unexpected_handler, unexpected) (get_unexpected, set_unexpected): Add deprecated attribute. Do not define without _GLIBCXX_USE_DEPRECATED for C++17 and up. * libsupc++/eh_personality.cc (PERSONALITY_FUNCTION): Disable deprecated warnings. * libsupc++/eh_ptr.cc (std::rethrow_exception): Likewise. * libsupc++/eh_terminate.cc: Likewise. * libsupc++/eh_throw.cc (__cxa_init_primary_exception): Likewise. * libsupc++/unwind-cxx.h (struct __cxa_exception): Use terminate_handler instead of unexpected_handler.

2021-10-11libstdc++: Add wrapper for internal uses of std::terminateJonathan Wakely1-1/+1
This adds an inline wrapper for std::terminate that doesn't add the declaration of std::terminate to namespace std. This allows the library to terminate without including all of <exception>. libstdc++-v3/ChangeLog: * include/bits/atomic_timed_wait.h: Remove unused header. * include/bits/c++config (std:__terminate): Define. * include/bits/semaphore_base.h: Remove <exception> and use __terminate instead of terminate. * include/bits/std_thread.h: Likewise. * libsupc++/eh_terminate.cc (std::terminate): Use qualified-id to call __cxxabiv1::__terminate.

2019-05-31PR libstdc++/90682 allow set_terminate(0) and set_unexpected(0)Jonathan Wakely1-0/+7
Make these functions restore the default handlers when passed a null pointer. This is consistent with std::pmr::set_default_resource(0), and also matches the current behaviour of libc++. In order to avoid duplicating the preprocessor condition from eh_term_handler.cc more that into a new eh_term_handler.h header and define a macro that can be used in both eh_term_handler.cc and eh_terminate.cc. PR libstdc++/90682 * libsupc++/eh_term_handler.cc: Include eh_term_handler.h to get definition of _GLIBCXX_DEFAULT_TERM_HANDLER. * libsupc++/eh_term_handler.h: New header defining _GLIBCXX_DEFAULT_TERM_HANDLER. * libsupc++/eh_terminate.cc: Include eh_term_handler.h. (set_terminate): Restore default handler when argument is null. (set_unexpected): Likewise. * testsuite/18_support/set_terminate.cc: New test. * testsuite/18_support/set_unexpected.cc: New test.
