arm

Description

This interface is implemented by ARM processors to provide various functionality that is specific for this class of processors.

The read_register_mode and write_register_mode functions are used to access banked copies of the registers. They are used just like the int_register interface read and write functions, except that they take an extra parameter mode that specifies which register bank should be used. mode should be the mode bits in the cpsr corresponding to the mode shifted right to bits 0-4.

SIM_INTERFACE(arm) {
        uint64 (*read_register_mode)(conf_object_t *processor_obj,
                                     int reg_num, int mode);
        void (*write_register_mode)(conf_object_t *processor_obj,
                                    int reg_num, int mode, uint64 value);
};
