Because I feel bad for giving a non-answer: An easy way to find if a virtual register is alive after the basic block is to While iterating over the virtual registers - Check to see if the virtual register's "next" value exists outside of the basic block. for instance: std::vector<unsigned> findLiveOut( MachineBasicBlock * mbb ) { std::vector<unsigned> liveout; for(

Is there an easy way to obtain all liveout variables of a basic block? Liveins can be found for each MachineBasicBlock, but I can only find liveouts for the whole function, at MachineRegisterInfo. Do I need to find them out manually?
