Convert the first AMDGPU buildbots to use the ScriptedBuilder introduced llvm-zorg. For the motivation, see https://github.com/llvm/llvm-zorg/pull/648. Since the production buildbot still needs to be restarted for ScriptedBuilder to work, only convert the builders that are currently in staging for now. These are: * openmp-offload-amdgpu-runtime * openmp-offload-amdgpu-clang-flang Both of them happen to be OpenMPBuilder.getOpenMPCMakeBuildFactory-based builders before this change. They also set an environment variable that the previous ScriptedBuilder did not, so we are adding support. The corresponding llvm-zorg change is https://github.com/llvm/llvm-zorg/pull/697.
The LLVM/Offload Subproject
The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.
For OpenMP offload users, the project is ready and fully usable. The final API design is still under development. More content will show up here and on our webpage soon. In the meantime, people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.
