It is conflicting with Clang's definition of `kmp_task_t` in `clang/lib/CodeGen/CGOpenMPRuntime.cpp`, so the struct gets renamed to `kmp_task_t.0` and `kmp_task_t.1`. I don't think it is that simple to update the usage of `kmp_task_t` in `clang/lib/CodeGen/CGOpenMPRuntime.cpp`. Should I rename my addition of `kmp_task_t` in `OMPKinds.def` to `kmp_task`, or should I just fix the tests to allow `kmp_task_t.0` and `kmp_task_t.1`?

The only way I can think of doing this is doing similarly to D123460 <https://reviews.llvm.org/D123460>, which is basically building the structure in OMPIRBuilder, and calling it in Clang. This is not a straightforward change to make though, because Clang builds several `RecordDecl`s on top of `kmp_task_t` such as the taskloop_task and task_with_privates. We would also have to build those structs in OMPIRBuilder, but that expands the scope of this patch quite significantly. Is this what you meant @jdoerfert?

Sorry for the delay. Yes, we should create all the structs in the OMPIRBuilder (or similar) and stop doing records in clang.
