Advanced Optimizations in Modern Compilers: JIT, AOT and Hybrid Pipelines

Modern software demands high performance, portability, and adaptability, driving innovations in compiler technologies. This article investigates advanced optimization strategies in modern compilers, focusing on Just-In-Time (JIT), Ahead-of-Time (AOT), and hybrid compilation pipelines. Using architectural modeling, benchmark-based simulations, and comparative analysis, the study demonstrates how hybrid compilers combine static and dynamic optimizations to maximize runtime performance while maintaining determinism and portability. The results provide valuable insights for future compiler design and adaptive optimization strategies.
