Summary: Right now this will fail because the GPU architectures will attempt to build all of `offload` with the GPU, which obviously won't work. In the future we will proably have some utility library that we will route through this, but for now just silently return. This is useful because the documentation states to use this, but it doesn't work right now. ``` -DLLVM_ENABLE_RUNTIMES=offload;openmp -DLLVM_RUNTIME_TARGETS=default;amdgcn-amd-amdhsa ``` This PR makes this work.
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.
