Compilers: Five Different Local Optimizations
In this video we will learn about five different local optimizations:
1) Constant Folding: simplifying expressions involving constants and performing arithmetic operations at compile-time, reducing runtime overhead.
2) Arithmetic Simplification: Simplifying complex arithmetic expressions.
3-4) Copy and Constant Propagation: A technique that replaces the usage of variables with their values where possible.
4) Common Subexpression Elimination: Learn how to identify and eliminate redundant computations in your code. Common Subexpression Elimination optimizes by identifying and reusing previously computed expressions, resulting in a leaner and faster program.
