  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=... \
  25 #    [REMOTE_TMPDIR=${remote_dir}] [GDBSERVER=${remote_gdbserver}]"
