Currently we don't check for the presence of descriptor/BoxTypes before emitting stores which lower to memcpys, the issue with this is that users can have optional arguments, where they don't provide an input, making the argument effectively null. This can still be mapped and this causes issues at the moment as we'll emit a memcpy for function arguments to store to a local variable for certain edge cases, when we perform this memcpy on a null input, we cause a segfault at runtime. The fix to this is to simply create a branch around the store that checks if the data we're copying from is actually present. If it is, we proceed with the store, if it isn't we skip it.
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.
