* Atomic test: Fix use after freeJoel Linn2020-12-231-8/+2
| | | | | | SDL_SemPost() was called by the FIFO threads after the semaphore was freed because the main thread actually synchronized on the `writerRunning`/`readersRunning` count and not the semaphores itself.

* Remove almost all instances of "volatile" keyword.Ryan C. Gordon2016-01-031-6/+6
| | | | | | | | | | | As Tiffany pointed out in Bugzilla, volatile is not useful for thread safety: https://software.intel.com/en-us/blogs/2007/11/30/volatile-almost-useless-for-multi-threaded-programming/ Some of these volatiles didn't need to be, some were otherwise protected by spinlocks or mutexes, and some got moved over to SDL_atomic_t data, etc. Fixes Bugzilla #3220.

| | | | | | | | | | you should start working with to port atomic ops. The linux code appears to be complete and *should* be the base of all Unix and GCC based versions. The macosx and win32 versions are currently just copies of the dummy code. I will begin working on the windows version as soon as this check in is done. I need someone to work on the Mac OS X version. I'm afraid that this check in will break QNX (Sorry!)

| | | | | | | | | | | | | | | | | | | | stuff in. /test/testatomic.c performs absolutely basic tests to show that the function work as expected. Need a second test to do more detailed tests. /include/SDL_atomic.h provides declarations for all included functions. /src/atomic/linux/SDL_atomic.c provided all the functions. On a generic built the 64 bit functions work, but they are emulated. On a build for -march=pentium and above the 64 bit functions use native instructions /src/atomic/dummy/SDL_atomic.c emulates all the operations using SDL_mutex.h. /src/atomic/win32/SDL_atomic.c is a copy of dummy /src/atomic/macosx/SDL_atomic.s is a copy of dummy These versions of SDL_atomic.c provide a frame work for building the library with a mixture of native and emulated functions. This allows the whole library to be provided on all platforms. (I hope.) I hope this fits with the SDL philosophy of either providing a common subset or emulating when the platform is missing a feature. I have not added dummy, macosx, or win32 to the build. They are there as place holders for future work. I have modified congifure.in to compile sources in /src/atomic/linux. (The SDL configure.in file is an amazing piece of work and I hope I didn't mess it up. :-)

They are being checked in as place holders. Mostly, I just wanted to get place holders and the configure.in checked in.
