[Openmp-commits] [PATCH] D131830: [OpenMP] Clang Support for taskwait nowait clause

[Joachim Protze via Phabricator via Openmp-commits]

protze.joachim added a comment.

Why do we need __kmpc_omp_taskwait_51 ? Taskwait nowait only makes sense with dependencies. It should only result in additional nodes/edges in the task dependency graph without any code to execute. There is not taskwait (aka task barrier) in this case.

The taskwait construct has the restriction in the spec:

> The **nowait** clause may only appear on a **taskwait** directive if the **depend** clause is present.
