Hi,
We see the following fail in the real remote testing...
(gdb) Executing on target: kill -9 29808 (timeout = 300)
spawn [open ...]^M
sh: 1: kill: No such process
XYZ1ZYX
tstatus^M
Trace can not be run on this target.^M
(gdb) FAIL: gdb.server/server-kill.exp: tstatus
The test tries to kill gdbserver in this way:
set server_pid [exp_pid -i [board_info target fileid]]
remote_exec target "kill -9 $server_pid"
in native testing, we'll get the pid of spawned gdbserver, however, in
remote testing, we'll get the pid of ssh session, since we start
gdbserver on the remote target through ssh. The pid on build doesn't
exist on target.
I thought about different ways to handle remote target, for example:
- use command ps on remote target to gdbserver pid, but it doesn't work
if we have multiple gdbserver instances during testing,
- port number can be regarded as an id to differentiate different
instances, but port number is unknown to each test case. Likewise,
we can't use 'pkill' due to the same reason.
- close the gdbserver channel, but gdbserver doesn't exit on the target,
then, I have to skip this test for remote target.

* gdb.server/server-kill.exp: Skip it if the target is remote.
