| H A D | misc64.hh | 13364:055bf0fa0f02 Wed Oct 24 08:34:00 EDT 2018 Giacomo Travaglini <giacomo.travaglini@arm.com> arch-arm: Refactor AArch64 MSR/MRS trapping This patch refactors AArch64 MSR/MRS trapping, by moving the trapping helpers in arch/arm/utility and in the isa code into a MiscRegOp64 class. This class is the Base class for a generic AArch64 instruction which is making use of system registers (MiscReg), like MSR,MRS,SYS. The common denominator or those instruction is the chance that the system register access is trapped to an upper Exception level. MiscRegOp64 is providing that feature. What do we gain? Other "pseudo" instructions, like access to implementation defined registers can inherit from this class to make use of the trapping functionalities even if there is no data movement between GPRs and system register.
