        Size of buffer to use for tracking memory allocations within
        instrumentation. This setting has no effect if you are not using the
        allocation instrumentation. Setting this value to 0 disables pointer
        tracking.

    help
        Instrumentation to apply to function calls. This setting will only have
        an effect when your CFLAGS include -finstrument-functions, in which
        case __cyg_profile_func_enter will be called on every function entry
        and __cyg_profile_func_exit will be called on every function exit. The
        value of this setting determines the implementation of
        __cyg_profile_func_enter and __cyg_profile_func_exit supplied by this
        library. Regardless of the option you select, you can always override
        the implementation by providing your own in your application.

    bool "none"
    help
        No implementation of __cyg_profile_func_enter and
        __cyg_profile_func_exit are provided.

    bool "printf trace"
    help
        Print entry and exit of every function call. This option is useful for
        a very coarse and noisy description of what your code is doing.

    config LIBSEL4DEBUG_FUNCTION_INSTRUMENTATION_BACKTRACE
    bool "backtrace"
    help
        Track function calls for the purposes of a backtrace. You will need to
        enable this option if you want to retrieve programmatic backtraces.
