For example, handling an invalid opcode may result in sending a SIGILL signal to the user task. A - debug excpetion will send a SIGTRAP signal. + debug exception will send a SIGTRAP signal. In both cases, if the exception occurred in user space, it is safe to enable interrupts early. Sending a signal requires both interrupts and kernel preemption to be enabled. |
