16# This file is a dejagnu "board file" and is used to run the testsuite
17# with a remotehost and gdbserver using stdio for communicating through
18# ssh. Certain firewalls prevent gdbserver from using the usual mechanism of
19# listening on a remote port, so use stdio via ssh instead.
20#
21# To use this file:
22# bash$ cd ${build_dir}/gdb
23# bash$ make check RUNTESTFLAGS="--target_board=remote-stdio-gdbserver \
24#    REMOTE_USERNAME=... REMOTE_HOSTNAME=... REMOTE_PORTNUM=... \
25#    [REMOTE_TMPDIR=${remote_dir}] [GDBSERVER=${remote_gdbserver}]"
