29
 *   REASONS WHY NINDY CAN STOP EXECUTING AN APPLICATION PROGRAM
30
 *
31
 * When NINDY stops executing an application program that was running
32
 * under remote host ("gdb") control, it signals the host by sending
33
 * a single ^P.  The host can then query as to the reason for the halt.
34
 * NINDY responds with two bytes of information.
35
 *
36
 * The first byte is a boolean flag that indicates whether or not
37
 * the application has exited.
38
 *
39
 * If the flag is true, the second byte contains the exit code.
40
 *
41
 * If the flag is false, the second byte contains a "reason for
42
 * stopping" code.  This file defines the possible values of that
43
 * code.
44
 *
45
 * There are three categories of reasons why the halt may have occurred:
46
 * faults, traces, and software interactions.  The first two categories
47
 * are processor-dependent; the values of these codes are tightly coupled
48
 * to the hardware and should not be changed without first examining
49
 * src/nindy/common/fault.c.  The software interactions involve
50
 * communication between NINDY and the host debugger;  their codes are
51
 * arbitrary.
