Applications of Semantic Analysis
Semantic Analysis extends beyond basic syntactical validation to validate the logical consistency of programs through a comprehensive check of their meaning. It is integral to the compilation process, employing Syntax-Directed Translation Schemes to manage declarations and type correctness, ultimately translating to an initial intermediate representation known as three-address code.

What we have learnt
- Semantic Analysis ensures that code not only adheres to grammatical rules but is also logically sound.
- Core functionalities include collecting identifier information, enforcing context-sensitive rules, and generating intermediate representations.
- Three-Address Code provides a simplified method of representing operations, facilitating optimization and machine independence.
Key Concepts
- -- Semantic Analysis
- The phase in the compilation process that verifies the logical consistency and meaning of the code beyond its syntax.
- -- Symbol Table
- A data structure that acts as a dictionary for identifiers in the program providing essential details like type, scope, and memory location.
- -- ThreeAddress Code (TAC)
- An intermediate representation that simplifies complex expressions and control flow into a linear series of instructions.
- -- SyntaxDirected Translation (SDT)
- A method that integrates semantic processing into syntactic analysis by triggering actions as grammar rules are reduced.
- -- Type Checking
- The process of ensuring that operations in the program are performed on compatible data types.
