This pull request is the third part of an ongoing effort to extends PGO instrumentation to GPU device code and depends on https://github.com/llvm/llvm-project/pull/93365. This PR makes the following changes: - Allows PGO flags to be supplied to GPU targets - Pulls version global from device - Modifies `__llvm_write_custom_profile` and `lprofWriteDataImpl` to allow the PGO version to be overridden
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.
