| * x86inc: Avoid using eax/rax for storing the stack pointerHenrik Gramner2017-01-09
| | | | | | | | | | | | | | | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* | libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1Aaron Levinson2017-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1. This is only relevant when thread.h is included by C++ files. In this case, the relevant code is only defined if HAVE_PTHREADS is defined as 1. Use configure --assert-level=2 to do so. Note: Issue discovered as a result of Coverity build failure. Cause of build failure pinpointed by Hendrik Leppkes. Comments: -- libavutil/thread.h: Altered ASSERT_PTHREAD_NORET definition such that it uses av_make_error_string instead of av_err2str(). av_err2str() uses a "parenthesized type followed by an initializer list", which is apparently not valid C++. This issue started occurring because thread.h is now included by the DeckLink C++ files. The alteration does the equivalent of what av_err2str() does, but instead declares the character buffer as a local variable. Signed-off-by: Marton Balint <cus@passwd.hu>

| * avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables |flags|, |cpuflags_mask|, and |checked| in libavutil/cpu.c are 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. Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition. Rename |flags| to |cpu_flags| and move it to file scope. 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.
