CONSTANT PROPAGATION IN COMPILER DESIGN YouTube
This instruction has both the operands as constants and hence can be computed at compile time, thus getting the result a = 20. The aim of our analysis is to determine for each program point, whether a variable has a constant value whenever the execution reaches that point. Y = x + 4; Terms in constant expressions are typically simple literals, such as the integer literal 2, but they may also be variables whose values are known at compile time.

Cedures, the compiler can generate better code for a specific procedure if it knows which variables will have constant values, and what those values will be, when the procedure is invoked. Constant propagation in compiler design and constant folding in compiler design is used for local optimization in compiler design. Constant folding is the process of recognizing and evaluating constant.

Constants assigned to a variable can be propagated through the flow graph and substituted at the use of the variable. This is.

For example, if you assign x = 5, then y = x, then z = y * 3, then a = x + y + z, and there are no assignments interfering with this, then constant propagation tells as that y = 5, z = 5 * 3 (which turns into z = 15 after. Control flow graph for a.
