* REASONS WHY NINDY CAN STOP EXECUTING AN APPLICATION PROGRAM
|
||
|
|
*
|
||
|
|
* When NINDY stops executing an application program that was running
|
||
|
|
* under remote host ("gdb") control, it signals the host by sending
|
||
|
|
* a single ^P. The host can then query as to the reason for the halt.
|
||
|
|
* NINDY responds with two bytes of information.
|
||
|
|
*
|
||
|
|
* The first byte is a boolean flag that indicates whether or not
|
||
|
|
* the application has exited.
|
||
|
|
*
|
||
|
|
* If the flag is true, the second byte contains the exit code.
|
||
|
|
*
|
||
|
|
* If the flag is false, the second byte contains a "reason for
|
||
|
|
* stopping" code. This file defines the possible values of that
|
||
|
|
* code.
|
||
|
|
*
|
||
|
|
* There are three categories of reasons why the halt may have occurred:
|
||
|
|
* faults, traces, and software interactions. The first two categories
|
||
|
|
* are processor-dependent; the values of these codes are tightly coupled
|
||
|
|
* to the hardware and should not be changed without first examining
|
||
|
|
* src/nindy/common/fault.c. The software interactions involve
|
||
|
|
* communication between NINDY and the host debugger; their codes are
|
||
|
|
* arbitrary.
