A compiler is a complex software system that plays a crucial role in the development of computer programs. Its primary function is to translate source code written in a high-level language, such as C or Java, into machine code that can be executed directly by the computer’s processor. The compilation process involves several stages, including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation.
V. Raghavan’s PDF on the principles of compiler design is a comprehensive resource that covers all the stages of the compilation process. The PDF provides a detailed overview of the lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. principles of compiler design v raghavan pdf

The semantic analyzer uses a symbol table to keep track of the symbols, such as variables and functions, declared in the program. Optimization is the fourth stage of the compilation process. In this stage, the compiler analyzes the intermediate code and applies various optimization techniques to improve the performance of the generated code.
The parser uses a set of production rules, known as a grammar, to analyze the tokens. The parser builds a parse tree, which represents the syntactic structure of the program. Semantic analysis, also known as analysis or checking, is the third stage of the compilation process. In this stage, the parser checks the parse tree for semantic errors, such as type errors or scoping errors.
