Explain in detail about peephole optimization
WebOptimization is a program transformation technique, which tries to improve the code by making it consume less resources (i.e. CPU, Memory) and deliver high speed. In optimization, high-level general programming constructs are replaced by very efficient low-level programming codes. A code optimizing process must follow the three rules given … WebMar 14, 2024 · 5. PRINCIPAL SOURCES OF OPTIMIZATION A transformation of a program is called local if it can be performed by looking only at the statements in a basic block; otherwise, it is called global. Many transformations can be performed at both the local and global levels. Local transformations are usually performed first.

WebIntroduction. In compiler design, code optimization is a program transformation technique that tries to improve the intermediate code to consume fewer resources such as CPU, memory, etc., resulting in faster machine code..
