Hi,
I happen to see gdbserver is spawned like this in gdb.log,
spawn /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2346 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.s
erver/connect-stopped-target/connect-stopped-target /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/connect-stopped-target/connect-stopped-t
arget
spawn /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.s
erver/connect-stopped-target/connect-stopped-target /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/connect-stopped-target/connect-stopped-t
arget
as we can see, there are two instances of connect-stopped-target or
connect-stopped-target in the command line spawning gdbserver, but
none of these gets parameters from command line. In these two
tests, gdbserver is spawned via "gdbserver_spawn ${binfile}". However,
the argument of gdbserver_spawn is the argument passed the child
inferior, not the program itself.
# Start a gdbserver process running SERVER_EXEC, and connect GDB
# to it. CHILD_ARGS are passed to the inferior.
#
# Returns the target protocol and socket to connect to.
proc gdbserver_spawn { child_args } {
set target_exec [gdbserver_download_current_prog]
GDBserver gets the program via last_loaded_file, which is set by
gdb_file_cmd. In each test, we don't need to pass ${binfile}.
gdb/testsuite:
2016-08-23 Yao Qi <yao.qi@linaro.org>
* gdb.server/connect-stopped-target.exp (do_test): Pass "" to
gdbserver_spawn.
* gdb.server/connect-without-multi-process.exp (do_test):
Likewise.
