What is a Compiler?
A Compiler is a software or a program that converts the human-readable code into something that a machine can understand. For example, the code that we write either in Java C++, or C language gets converted into machine-understandable binary code or assembly language by compilers.
Variable: A Variable is something like a named container for our data in the memory, that we can access and modify this data using the variable name.
Propagation: Propagation in simpler terms refers to the multiplication of something or the increase or spreading of something.
Code Optimization: Code optimizing refers to the process of modifying the code without changing the original functionality of the program so that it runs efficiently in terms of memory and speed. Optimized code generally takes less space time or both to finish the program.
Constant Propagation: Replacing the variables in the code with the known constants.
What is Variable Propagation?
In the compilation process, after generating the Intermediate code, the Compiler does code optimization to improve the performance of the code. So, before actually modifying the code for optimization, the compiler analyses the flow of variables in the code, that is compiler analyzes the code and variables, and based upon this analysis, the optimizer component of the compiler does code optimization. This analysis of the flow of variables throughout the code by the compiler is called variable propagation.
