Dependency Graphs
A dependency graph is a graphical representation that illustrates the syntactic relationships between the individual components (or modules) of a computer program. It visualizes the flow of information and dependencies between these components.
Example:
[Program Structure]
Dependencies:
The program consists of the following modules:
Parser
Compiler
Lexical Analyzer
Semantic Analyzer
Output Generator
Relationship between Modules:
The parser reads the program structure from the input file.
The parser is dependent on the lexical analyzer for token identification.
The parser is also dependent on the semantic analyzer for semantic analysis.
The output generator is dependent on the semantic analyzer for generating the output code.
Uses of Dependency Graphs:
They provide a clear and concise understanding of the program's syntactic structure.
They facilitate the analysis of compiler design, including identifying components, their relationships, and the flow of information.
They can be used to generate compiler code from a formal description of the program.
Additional Notes:
A dependency graph is a directed graph, with nodes representing modules and edges representing dependencies.
Each node represents a specific component, and each edge represents a direct dependency between two nodes.
The graph can be used to analyze the correctness and completeness of the compiler's syntactic analysis phase
