Implicit/Explicit task yielding in Clang v5.0.0 OpenMP Implementation

David Blaikie via cfe-dev

While an implementation of OpenMP is *allowed* to insert implicit switching points in a task region (i.e., #pragma omp task), I as the developer can make use of the standard’s explicit task yielding if need be (i.e., #pragma omp taskyield). My question is whether the Clang v5.0.0 implementation employs such implicit task yielding, or is it necessary for me to do so explicitly?
