5.5.2 angel_SWIreason_ReportException (0x18)

This SWI can be called by an application to report an exception to the debugger directly.

The most common use is to report that execution has completed, using

ADP_Stopped_ApplicationExit

Entry

On entry r1 is set to one of the values listed in Table 5-3 and Table 5-4. These values are

defined in

adp.h

The hardware exceptions are generated if the debugger variable

$vector_catch

is set to

catch that exception type, and the debug agent is capable of reporting that exception

type. Angel cannot report exceptions for interrupts on the vector it uses itself.

Exception handlers can use these SWIs at the end of handler chains as the default action,

to indicate that the exception has not been handled.
