- Correct GSL path to report targets using the TargetID syntax. - Correct GSL path to check compatibility of code objects when loading. - Add concept of an device isa and create a registery used by ROCm, PAL and GSL. - Support XNACK and SRAMECC target features consistently for PAL and ROCm. - Correct logic for NullDevices and asserts to avoid memory coruption. - Allow all NullDevices to be created for HIP. - Numerous other code improvements.
