Message-ID: <6lrurs$4fm$1@news2.apple.com> (raw)
Paragraph 7 of Section C.3 of the ARM says that exceptions cannot be
propagated from interrupt handlers. Does this mean that an interrupt
handler cannot raise something like Constraint_Error, and expect a task's
exception handler to be invoked? Is there any way for an interrupt
handler to cause a task's exception handler to be invoked, or to somehow
cause the termination of the task that was executing when the interrupt
occurred? (For the purposes of this discussion, one could envision an
interrupt handler for page faults, in which one might want to raise some
exception, and either have the program's exception handler take some
action, or terminate the program itself.)
