The problem seems to be caused by the m5.cpt in the checkpoint I acquired not having arm-sve tag and vecPredRegs. However, if I run cpt_upgrader.py on the checkpoint, it adds the arm-sve tag without doing anything about the absence of vecPredRegs. Does anyone know a workaround without reverting my gem5 codebase to an ancient version?
