+- The LLVM OpenMP runtime `libomp` now supports the OpenMP Tools Interface (OMPT)
+ on x86, x86_64, AArch64, and PPC64 on Linux, Windows, and macOS. If you observe
+ a measurable performance impact on one of your applications without a tool
+ attached, please rebuild the runtime library with `-DLIBOMP_OMPT_SUPPORT=OFF` and
+ file a bug at `LLVM's Bugzilla <>`_ or send a message to the
+ `OpenMP development list <>`_.
