Peephole Optimization in Compiler Design

In terms of compiler optimization, classical compilers used a method called Peephole Optimization, which is a powerful optimization approach. During the early stages of implementation, this approach was mostly used with string pattern matching on regular expressions, which are known as classic peephole optimizers. The string pattern matching technique is considered as a processing of the input of the syntax of assembly code in classical optimizers, but its meaning is lost. This article analyses ...
