AtomC Compiler

A simple C compiler for the AtomC programming language made for Compilation Techniques class. The compiler includes:

Lexical Analyzer:

The lexical analyzer is responsible for breaking the input source code into a sequence of tokens. It scans the input source code and converts it into a sequence of tokens that can be used by the other components of the compiler.

Syntactic Analyzer:

The syntactic analyzer takes the token sequence generated by the lexical analyzer and checks if the sequence of tokens corresponds to a valid program according to the AtomC programming language grammar. If the sequence is valid, it generates an abstract syntax tree (AST) that represents the program's structure.

Semantic Analysis:

The semantic analysis component checks the AST generated by the syntactic analyzer for semantic errors. This includes checking for variable declarations, function declarations, and type mismatches.

My implementation

• The lexical analyzer is based on the diagram below:

Project Structure

• src/: Contains the source code files.

  • main.c: Main program logic.
  • lexer.c: token functions and states logic.
  • utils.c: utility functions.
  • parser.c: syntactic analyzer
  • da.c: domain analysis and symbol tables

• include/: Holds header files.

• obj/: Houses object files generated during compilation.

• bin/: Stores the executable files.

• Makefile: The Makefile for building the project.

• README.md: Documentation providing an overview of the project, its features, and instructions for usage.

• diagram.png: Lexical analyzer states diagram

• token-list.txt: List of tokens generated from lexical analyzer

Usage

Go to the project folder and just type:
