Dead elimination: A variable is live at a point in a program if its value can be used subsequently. Otherwise it is dead at that point. Let us a variable x is dead. That is, never subsequently used, at the point where the statement x : = y + z appears in a basic block. Then this statement may be safely removed without changing the value of the basic block.
