Author: redi Date: Tue May 5 21:32:38 2009 New Revision: 147137 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=147137 Log: 2009-05-05 Jonathan Wakely <jwakely....@gmail.com> PR libstdc++/39909 * include/std/mutex (__get_once_functor_lock, __get_once_mutex, __set_once_functor_lock_ptr): Replace global lock object with local locks on global mutex. * src/mutex.cc (__get_once_functor_lock, __get_once_mutex, __set_once_functor_lock_ptr): Likewise, keeping old function to preserve ABI. (__once_proxy): Use pointer to local lock if set, global lock otherwise. * config/abi/pre/gnu.ver: Add new symbols to new ABI version. * testsuite/util/testsuite_abi.cc: Add GLIBCX_3.4.12 version. * testsuite/30_threads/call_once/39909.cc: New.
