  16 # This file is a dejagnu "board file" and is used to run the testsuite
  17 # against local host, in remote host mode.
  18 #
  19 # This board file is used to emulate the real remote host testing, in
  20 # which file system of host and build are not shared.  This is achieved
  21 # by copying files from source directory to ${host_dir}.
  22 #
  23 # To use this file:
  24 # bash$ cd ${build_dir}/gdb
  25 # bash$ make check RUNTESTFLAGS="--host_board=local-remote-host-native --target_board=local-remote-host-native HOST_DIR=/tmp/foo/"
  26 #
  27 # We set both target board and host board together to test a native gdb
  28 # (host == target) on a remote host (host != build).  $HOST_DIR is the
  29 # directory for copying files to, to avoid messing up your HOME.  When
  30 # it is absent, files are copied to ./remote-host.
  31

  36 # We have to explicitly specify GDB with the path to the copy in
  37 # the build directory because otherwise it will be set to the
  38 # result of "transform GDB" since the harness thinks we're using
  39 # a remote host.  See lib/gdb.exp.
