In order to efficiently handle system register access being disabled, and this resulting in an UNDEF exception being injected, we introduce the (slightly dubious) concept of Fine-Grained UNDEF, modeled after the architectural Fine-Grained Traps. For each FGT group, we keep a 64 bit word that has the exact same bit assignment as the corresponding FGT register, where a 1 indicates that trapping this register should result in an UNDEF exception being reinjected. So far, nothing populates this information, nor sets the corresponding trap bits.
