C Code Optimizer

A compiler-style optimization tool for C programs that performs static analysis and applies optimization techniques to improve code efficiency.

• Control Flow Graph (CFG) construction
• Dead Code Elimination (DCE)
• Constant Folding
• CFG visualization
• Code simplification and optimization

Compilers optimize code to improve performance and reduce unnecessary computations. This project explores core compiler techniques and demonstrates how code can be transformed for efficiency.

• Language: Python / C++
• Graph Visualization: Graphviz / custom rendering

1. Constant Folding

Evaluates constant expressions at compile time.

2. Dead Code Elimination

Removes code that does not affect program output.

3. Control Flow Graph (CFG)

Represents program structure for analysis and transformations.

📊 Workflow

1. Parse input C code
2. Generate intermediate representation (IR)
3. Build CFG
4. Apply optimization passes
5. Output optimized code
