Currently, Flang can generate no-loop kernels for all OpenMP target kernels in the program if the flags -fopenmp-assume-teams-oversubscription or -fopenmp-assume-threads-oversubscription are set. If we add an additional parameter, we can choose in the future which OpenMP kernels should be generated as no-loop kernels. This PR doesn't modify current behavior of oversubscription flags. RFC for no-loop kernels: https://discourse.llvm.org/t/rfc-no-loop-mode-for-openmp-gpu-kernels/87517
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.
