Summary: As suggested in https://github.com/llvm/llvm-project/pull/177665, we should build a GPU version of the compiler-rt profile library instead of writing it in-line in the lowering. This PR does not define anything GPU specific, it simply re-uses the baremetal handling. Later PRs will prevent the GPU specific handling we would want to do to optimize counter handling on the GPU. Note that this will require using the cache file, or setting these options manually for existing users. Hopefully if people are using the cache file as they should it won't break anything.
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.
