- The __NOP() that was added in #8518 is now remooved. - When DBG_STANDBY, DBG_STOP or DBG_SLEEP are set in DBG_CR a hardfault occurs on wakeup from sleep. This was first diagnosed in #8518. When enabled, a hardfault occured when returning from a branch to irq_restore() we avoid the call by inlining the function call. See #11830 for more details.
