When compiling with gcc on ia64 architecture, the `__TBB_machine_fetchadd4` will be left undefined. https://github.com/oneapi-src/oneTBB/blob/master/src/tbb/tools_api/ittnotify_config.h#L327-L331 Why not replace the `TODO` comment with the fallback implementation? ``` #define __TBB_machine_fetchadd4(addr, val) __sync_fetch_and_add(addr, val)...
