## Summary While delivering a signal to a task that is currently running on the other core (SMP-enabled), the xtensa_sig_deliver needs to leave the critical section first. This should use the interrupt state (PS register) of the previously duplicated registers set explicitly for the signal handler. The saved state (saved registers prior to the task's interruption to treat the signal) should only be used when restoring the task's registers after signal handling. ## Impact This allows running tasks to receive a signal while they are running on the other core in an SMP-enabled environment. ## Testing This behavior can be verified by selecting `EXAMPLES_ALARM` app. In order to force the task to be running, one could omit `usleep` on `alarm_main.c`. Prior to this commit, the application crashed while delivering the signal to the app. -- This is an automated message from the Apache Git Service.
