Does the MPC8270 double synchronize the input LGTA?

Direction is from the outside world going into the MPC8270.  This is asking what the 8270 does when the setup and hold time cannot be met, if it provides two series flip flops at the input, or not- perhaps to have less latency?  If the outside signal cannot make the setup time and presents an edge at the threshold point, will there simply be a one clock delay before the LGTA signal is seen, or will/might there be a metastability condition in the MPC8270?

Is there a list of inputs that are double synchronized?
