RFR(XS) JDK-8013830: [parfait] Uninitialised pointer 'Reachblock' may be used as argument

[Niclas Adlertz]

Hi all,

The uninitialized pointer 'Reachblock' can be replaced with NULL at the call since the node we are re-materializing will not have any live range input (because of contains_no_live_range_input(def)).

Kind Regards,
