However, looking at this I've got a question: How about "imposing a function name" which is listed as a difference of noblock versus others? This (the specific name) is not actually documented anywhere? Is that an omission, or am I missing something?

  • Support has been added for the noblock function attribute. It can be specified together with the signal attribute to - indicate that the interrupt service routine should start with a SEI - instruction to globally re-enable interrupts. The difference to the - interrupt attribute is that the noblock - attribute just acts like a flag and does not impose a specific function - name.
