52 Q: How to build an OpenMP GPU offload capable compiler?
70 To manually build an *effective* OpenMP offload capable compiler, only one extra CMake
71 option, ``LLVM_ENABLE_RUNTIMES="openmp;offload"``, is needed when building LLVM (Generic
74 are targeted by OpenMP are enabled. That can be done by adjusting the CMake
78 ``LLVM_ENABLE_RUNTIMES="openmp"`` OpenMP should not be enabled in

93 Q: How to build an OpenMP Nvidia offload capable compiler?
95 The Cuda SDK is required on the machine that will execute the openmp application.
108 Q: How to build an OpenMP AMDGPU offload capable compiler?
111 required to build the LLVM toolchain and to execute the openmp application.
118 OpenMP's perspective. Rocr is an implementation of `HSA
123 SOURCE_DIR=same-as-llvm-source # e.g. the checkout of llvm-project, next to openmp
144 ``IMAGE_SUPPORT`` requires building rocr with clang and is not used by openmp.
165 Q: What are the known limitations of OpenMP AMDGPU offload?
183 - ``libomp.so`` (or similar), the host openmp runtime
184 - ``libomptarget.so``, the target-agnostic target offloading openmp runtime
205 as ``openmp.cfg`` next to your ``clang`` executable.

240 Q: Does OpenMP offloading support work in pre-packaged LLVM releases?
244 Q: Does OpenMP offloading support work in packages distributed as part of my OS?
251 Q: Does Clang support `<math.h>` and `<complex.h>` operations in OpenMP target on GPUs?
254 Yes, LLVM/Clang allows math functions and complex arithmetic inside of OpenMP
269 vendor, in an OpenMP begin/end declare variant. These functions will then be
273 `extensions to the OpenMP begin/end declare variant context selector
282 By using ``libomptarget.rtl.rpc.so`` and ``openmp-offloading-server``, it is
286 Q: Can I use dynamically linked libraries with OpenMP offloading?
293 Q: How to build an OpenMP offload capable compiler with an outdated host compiler?
296 Enabling the OpenMP runtime will perform a two-stage build for you.
306 Q: How can I include OpenMP offloading support in my CMake project?
309 Currently, there is an experimental CMake find module for OpenMP target
310 offloading provided by LLVM. It will attempt to find OpenMP target offloading
311 support for your compiler. The flags necessary for OpenMP target offloading will
317 ``find_package``. The module will be installed with your OpenMP installation by
318 default. Including OpenMP offloading support in an application should now only

352 Q: Can OpenMP offloading compile for multiple architectures?
355 Since LLVM version 15.0, OpenMP offloading supports offloading to multiple

416 Q: Can I link OpenMP offloading with CUDA or HIP?
419 OpenMP offloading files can currently be experimentally linked with CUDA and HIP
420 files. This will allow OpenMP to call a CUDA device function or vice-versa.
