| build. | |
| ### Device Runtime | |
| - Changed the OpenMP DeviceRTL to use 'generic' IR. The | |
| `LIBOMPTARGET_DEVICE_ARCHITECTURES` CMake argument is now unused and will | |
| always build support for AMDGPU and NVPTX targets. | |
| - Updated the offloading entry format but retained backwards compatibility with | |
| the old format. | |
| - The LLVM_ENABLE_PROJECTS=openmp build mode has been removed. | |
