Summary: We rely on these flags to do things in the runtime and print the contents of binaries correctly. CUDA updated their ABI encoding recently and we didn't handle that. it's a new ABI entirely so we just select on it when it shows up. Fixes: https://github.com/llvm/llvm-project/issues/148703 [LLVM] Fix offload and update CUDA ABI for all SM values (#159354) Summary: Turns out the new CUDA ABI now applies retroactively to all the other SMs if you upgrade to CUDA 13.0. This patch changes the scheme, keeping all the SM flags consistent but using an offset. Fixes: https://github.com/llvm/llvm-project/issues/159088
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.
