The C, c, S, s and ? packets can receive any of the below as a reply. In the case of the C, c, S and s packets, that reply is only returned when the target halts. In the below the exact meaning of signal number is poorly defined. In general one of the UNIX signal numbering conventions is used.
T
AAn...:
r...;
n...:
r...;
n...:
r...;
REGISTER_RAW_SIZE
; n... = thread, r... =
thread process ID, this is a hex integer; n... = (watch |
rwatch | awatch, r... = data address, this is a hex
integer; n... = other string not starting with valid hex digit.
GDB should ignore this n..., r... pair and go on
to the next. This way we can extend the protocol.
_start
; d... = base of data section; b... =
base of bss section. Note: only used by Cisco Systems targets.
The difference between this reply and the qOffsets query is that
the N packet may arrive spontaneously whereas the qOffsets
is a query initiated by the host debugger.
