When a processor enters a fast interrupts handler, and duplicate
register banks are configured, the processor saves the user context by
saving the registers in the main register bank to these additional
registers in the duplicate register bank.  In this fast interrupt
context, when you specify the rgf_banked_regs option,the compiler does
not save the registers duplicated in the additional register bank are
not saved.

The AUX_IRQ_CTRL register controls the behavior of automated register
save and restore or prologue and epilogue sequences during a non-fast
interrupt entry and exit, and context save and restore instructions.

A user passes to the compiler the configuration of the AUX_IRQ_CTRL
register via mirq-ctrl-saved option.  This option, specifies
gneral-purposes registers that the processor saves/restores on
interrupt entry and exit, and it is only valid for ARC EM and ARC HS
cores.
