- Update to v2021.8.0 * Fixed oneapi::tbb::concurrent_bounded_queue::pop return type (GitHub* #807). * Fixed oneapi::tbb::concurrent_queue and oneapi::tbb::concurrent_bounded_queue with non-default constructible value types (GitHub* #885). * Fixed incorrect splitting of iteration space in case there is no support for proportional splitting in custom ranges. - Add patch to link against libatomic where necessary * add-cmake-check-for-libatomic-requirement-when-build.patch - Drop 5cb212d44732947396abdd39eae1229c7cd51644.patch, merged upstream - Use correct changelog entries for v2021.7.0 * Memory allocator crash when allocating ~1TB on 64-bit systems (GitHub* #838). * Thread Distribution over NUMA Nodes on Windows OS systems. * For oneapi::tbb::suspend it is now guaranteed that the user-specified callable object is executed by the calling thread.
