Wan-Teh Chang fed50c4304 avutil: fix data race in av_get_cpu_flags() ... Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variable |cpu_flags| in libavutil/cpu.c is read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer. Co-author: Dmitry Vyukov of Google, who suggested the data race fix.
