Line 1: In [[~~computer~~compiler ~~science~~theory]], '''live variable analysis''' (or simply '''liveness analysis''') is a classic [[data flow analysis]] performed by [[compiler]]s to calculate for each program point the [[Variable (programming)\|variables]] that may be potentially read before their next write, that is, the variables that are ''live'' at the exit from each program point. Stated simply: a variable is '''live''' if it holds a value that may be needed in the future.
