Summary

Lecture 10 covers Introduction to Dataflow Analysis, including Value Numbering, Copy Propagation, and Dead Code Elimination. Value Numbering involves forward symbolic execution of a basic block, using maps such as Var2Val, Exp2Val, and Exp2Tmp to track variable and expression values. Copy Propagation uses forward propagation within a basic block, with maps tmp2var and var2set to replace temporary variables with actual variables. Dead Code Elimination uses backward propagation to remove unnecessary statements by tracking variables needed later in the computation. The next step is to apply these techniques to the entire procedure.
