Marian Buschsieweke 9e566370bf cpu/atmega_common: Fixed irq_arch implementation ... The inline assembly implementation was badly in need of improvement. - irq_disable() took 2 CPU cycles more than needed - The current interrupt state was stored in a temporary register and afterwards copied to the target register, rather than storing it in the target register right away - The lower bits of the state were cleared (as they have no meaning for the interrupt status), but the API purposely never required such things from implementations. - irq_restore() took 5 CPU cycles. This was reduced to 3 CPU cycles (or 2 CPU cycles in the best case)		2020-05-26 15:19:14 +02:00
