> A new option <code>-fcf-protection=[full|branch|return|none]</code> is
> introduced to perform a code instrumentation to increase program security by
> checking that target addresses of control-flow transfer instructions (such as
> indirect function call, function return, indirect jump) are valid. Currently
> the instrumentation is supported on x86 GNU/Linux target only. See, the user
> guide for further information about the option syntax and section "New Targets
