Hi Tanya, I personally have no current plans to extend OpenCLRuntime. The current OpenCLRuntime satisfies my own requirements. I designed OpenCLRuntime such that it might be extended by others for their own requirements. In this email to Anton Lokhmotov: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20110815/045187.html I explained the motivation for the CGOpenCLRuntime class: > One would develop support for a given OpenCL implementation > by implementing a subclass of CGOpenCLRuntime, and modifying > CodeGenModule::createOpenCLRuntime to return an instance of this > subclass when appropriate.
