COMPILER DESIGN

Detailed explanation-1: -It is the fifth stage of a compiler, and it allows you to choose whether or not to optimize your code, making it really optional. It aids in reducing the storage space and increases compilation speed. It takes source code as input and attempts to produce optimal code.

Detailed explanation-2: -There are 6 phases in the compiler, namely, lexical analysis, syntax analysis, semantics analysis, intermediate code generation, code optimization, and code generation. Symbol table is a data structure that the compiler generates and maintains to keep track of the semantics of variables.

Detailed explanation-3: -The process of compiling involves several stages, including syntax analysis, lexical analysis, semantic analysis, intermediate code generation, and code optimization, before finally producing the machine code output.
