# This test case verifies that if a display is active on a variable
# which belongs in a shared library, and that shared library is
# reloaded (e.g. due to re-execution of the program), GDB will continue
# to display it (gdb-6.8 crashed under this scenario).
# Also test that a display of variable which is currently present in
# a shared library, but disappears before re-run, doesn't cause GDB
# difficulties, and that it continues to display other variables.
# Finally, test that displays which refer to main executable
# (and thus aren't affected by shared library unloading) are not
# disabled prematurely.

# This test is currently not supported for stub targets, because it uses the
# start command (through gdb_start_cmd). In theory, it could be changed to
# use something else (kill + gdb_run_cmd with a manual breakpoint at main).
# However, when we try that with the native-gdbserver board, we see that the
# test fails and gdb outputs this upon connection:
#
# warning: Unable to display "a_global": No symbol "a_global" in current context.
# warning: Unable to display "b_global": No symbol "b_global" in current context.
# warning: Unable to display "c_global": No symbol "c_global" in current context.
#
# This is because the initial stop is done before the shared libraries are
# loaded.
