A new ErrorCode enumeration is present in PluginInterface which can be used when returning an llvm::Error from offload and PluginInterface functions. This enum must be kept up to sync with liboffload's ol_errc_t enum, so both are automatically generated from liboffload's enum definition. Some error codes have also been shuffled around to allow for future work. Note that this patch only adds the machinery; actual error codes will be added in a future patch. ~~Depends on #137339 , please ignore first commit of this MR.~~ This has been merged.
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.
