👉 Compiler missiles, also known as compiler optimizations or compiler transformations, are techniques employed by compilers to improve the performance, efficiency, or size of generated machine code without altering its external behavior. These optimizations can include simplifying expressions, eliminating redundant computations, reordering operations for better execution speed, and transforming data structures to reduce memory usage. By applying these transformations, compilers can produce more efficient code that executes faster or uses fewer resources, ultimately enhancing the overall performance of the software.
