* cancel.c: Rearranged some code and introduced checks
to disable cancelation at the start of a thread's cancelation run to prevent double cancelation. The main problem arises if a thread is canceling and then receives a subsequent async cancel request. * private.c: Likewise. * condvar.c: Place pragmas around cleanup_push/pop to turn off inline optimisation (/Obn where n>0 - MSVC only). Various optimisation switches in MSVC turn this on, which interferes with the way that cleanup handlers are run in C++ EH and SEH code. Application code compiled with inline optimisation must also wrap cleanup_push/pop blocks with the pragmas, e.g. #pragma inline_depth(0) pthread_cleanup_push(...) ... pthread_cleanup_pop(...) #pragma inline_depth(8) * rwlock.c: Likewise. * mutex.c: Remove attempts to inline some functions. * signal.c: Modify misleading comment. tests/ * mutex8: New test. * mutex8n: New test. * mutex8e: New test. * mutex8r: New test. * cancel6a: New test. * cancel6d: New test. * cleanup0.c: Add pragmas for inline optimisation control. * cleanup1.c: Add pragmas for inline optimisation control. * cleanup2.c: Add pragmas for inline optimisation control. * cleanup3.c: Add pragmas for inline optimisation control. * condvar7.c: Add pragmas for inline optimisation control. * condvar8.c: Add pragmas for inline optimisation control. * condvar9.c: Add pragmas for inline optimisation control.
