 \subsubsection*{Fold constants}
-Constant folding is an optimization where the outcome of arithmetics are calculated at compile time. If a value x is assigned to a certain value, let's say 10, than all next occurences of \texttt{x} are replaced by 10 until a redefinition of x. Arithmetics in Assembly are always preformed between two constants, if this is not the case the calculation is not possible. See the example for a more clear explanation of constant folding(will come). In other words until the current definition of \texttt{x} becomes dead. Therefore reaching definitions analysis is needed.
