Loop liveness is based on the following properties. +We only need to find the set of objects that are live at the birth or the header +of the loop. We don't need to calculate the live through the loop by considering +live in and live out of all the basic blocks of the loop. This is based on the +point that the set of objects that are live-in at the birth or header of the loop +will be live-in at every node in the loop. + +If a v live is out at the header of the loop then the variable is live-in at every node +in the loop. To prove this, consider a loop L with header h such that the variable v +defined at d is live-in at h. Since v is live at h, d is not part of L. This follows i +from the dominance property, i.e. h is strictly dominated by d. Furthermore, there +exists a path from h to a use of v which does not go through d. For every node p in +the loop, since the loop is strongly connected and node is a component of the CFG, +there exists a path, consisting only of nodes of L from p to h. Concatenating these +two paths proves that v is live-in and live-out of p. + +Calculate the live-out and live-in for the exit edge of the loop.
