Help text

SPR_SR_DSX bit is status register bit indicating whether the last exception has happened in delay slot.

OpenRISC architecture makes it optional to have it implemented in hardware and the OR1200 does not have it.

Say N here if you know that your OpenRISC processor has SPR_SR_DSX bit implemented. Say Y if you are unsure.
