Dmitry Vyukov b2be098026 tsan: fix signal handling in ignored libraries The first issue is that we longjmp from ScopedInterceptor scope when called from an ignored lib. This leaves thr->in_ignored_lib set. This, in turn, disables handling of sigaction. This, in turn, corrupts tsan state since signals delivered asynchronously. Another issue is that we can ignore synchronization in asignal handler, if the signal is delivered into an IgnoreSync region. Since signals are generally asynchronous, they should ignore memory access/synchronization/interceptor ignores. This could lead to false positives in signal handlers. llvm-svn: 261658		2016-02-23 17:16:26 +00:00
