The DeviceRTL functions updated by this patch are only used by Flang through the OMPIRBuilder at the moment, and there are no code paths in Clang that would result in calling these. I seem to remember @jdoerfert was working on / thinking about getting Clang to use them as well some time ago, but that's not yet upstream AFAICT.
