On Windows, for a reason I don't fully understand boolean bits get extra padding (even when asking for packed structures) in the structures that messes the offsets between the compiler and the runtime. Also, "weak" works differently on Windows than Linux (i.e., the "local" routine has preference) which causes it to crash as we don't really have an alternate implementation of __kmpc_omp_wait_deps. Given this, it doesn't make sense to mark it as "weak" for Linux either.
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.
