Debugging with GDB Manual (5900-1473; WDB 6.2; January 2011)

result → variable "=" value
variable → string
value → const | tuple | list
const → c-string
tuple → "{}" | "{" result ( "," result )* "}"
list → "[]" | "[" value ( "," value )* "]"
| "[" result ( "," result )* "]"
stream-record → console-stream-output |
target-stream-output |
log-stream-output
console-stream-output → "~" c-string
target-stream-output → "@" c-string
log-stream-output → "&" c-string
nl → CR | CR-LF
token → any sequence of digits.
Notes:
• All output sequences end in a single line containing a period.
• The token is from the corresponding request. If an execution command is interrupted
by the '-exec-interrupt' command, the token associated with the '*stopped'
message is the one of the original execution command, not the one of the interrupt
command.
• status-async-output contains on-going status information about the progress
of a slow operation. It can be discarded. All status output is prefixed by '+'.
• exec-async-output contains asynchronous state change on the target (stopped,
started, disappeared). All async output is prefixed by '*'.
• notify-async-output contains supplementary information that the client should
handle (for example, a new breakpoint information). All notify output is prefixed by
'='.
• console-stream-output is output that should be displayed as is in the console.
It is the textual response to a CLI command. All the console output is prefixed by
'~'.
• target-stream-output is the output produced by the target program. All the
target output is prefixed by '@'.
