Sam Lantinga 8077bf3d10 Fixed bug 2618 - incomplete pthread-based lock support should be removed
binarycrusader

Since changeset 358696c354a8, SDL 2.0 has been broken on Solaris when compiling with the Solaris Studio compiler (which uses the pthread implementation of SDL_AtomicLock).

Notably, it gets stuck at the MemoryBarrierRelease in SDL_GetErrBuf:

6585 # 218
6586     if (!tls_errbuf && !tls_being_created) {
6587          SDL_AtomicLock_REAL ( & tls_lock );
6588         if (!tls_errbuf) {
6589             SDL_TLSID slot;
6590             tls_being_created = SDL_TRUE;
6591             slot =  SDL_TLSCreate_REAL ( );
6592             tls_being_created = SDL_FALSE;
6593              { SDL_SpinLock _tmp = 0 ; SDL_AtomicLock_REAL ( & _tmp ) ; SDL_AtomicUnlock_REAL ( & _tmp ) ; };
^^^ loops forever above
6594             tls_errbuf = slot;
6595         }
6596          SDL_AtomicUnlock_REAL ( & tls_lock );
6597     }

As far as I can tell, this is because pthread_spin_trylock() always returns EBUSY for this particular lock; since it works in other places, I'm suspicious.

Different Solaris Studio compiler versions seem to make no difference.

I've verified this is broken on Linux as well if SDL_spinlock.c is modified to use the pthread implementation.

This appears to be because pthread_spin_init() and pthread_spin_destroy() are not used with the locks as required.
