Study Notes
Program Transformations and Optimizations
- Program transformations that improve the target code without considering any properties of the target machine are called machine-independent optimizations.
- Compilers that apply code-improving transformations are called optimizing compilers.
- The primary criteria for the best program transformations is correctness, ensuring the transformed code has the same semantics as the original code.
- Machine-dependent optimizations are based on the architecture and resources of the target machine, such as the number of registers, memory access patterns, and instruction latency.
- Program transformations applied by optimizing compilers can achieve faster execution, reduced memory usage, and improved code density.
- Machine-independent optimizations focus on improving the code structure and logic, while machine-dependent optimizations focus on exploiting the target machine's architecture and resources.
