Explanation:
Detailed explanation-1: -Peephole optimization comes under machine-dependent optimization. Machine-dependent optimization occurs after the target code has been generated and transformed to fit the target machine architecture. It makes use of CPU registers and may make use of absolute memory references rather than relative memory references.
Detailed explanation-2: -Optimization 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.
