[PATCH 6/7] notify in string_cmd and trace-notes.
Hi,
this patch is to change function add_setshow_string_cmd to return
'struct cmd_list_element *', and register command "trace-notes".
A new test case is added for it.
gdb:
2012-07-27 Yao Qi <yao@codesourcery.com>
* cli/cli-decode.c (add_setshow_string_cmd): Return 'struct
cmd_list_element *'.
* command.h: Update declaration.
* tracepoint.c (_initialize_tracepoint): Get the return value of
add_setshow_string_cmd and call set_cmd_notify.
gdb/testsuite:
2012-07-27 Yao Qi <yao@codesourcery.com>
* gdb.mi/mi-cmd-opt-changed.exp (test_command_option_change): Test for command
'set trace-notes'.
