Compiler Project

This is a university project focused on building a simple compiler. The main components of the project include:

• Lexical Analysis: Uses Flex (lexical.l) to generate a lexical analyzer that tokenizes the input source code.
• Syntax Analysis: Utilizes Bison (syntaxique.y) to define grammar rules for the language.
• Symbol Table Management: Stores and manages symbols, identifiers, and keywords found during compilation.
• Intermediate Code Generation: Creates quadruples to represent intermediate instructions.

Getting Started

Prerequisites

To compile and run the project, make sure you have the following tools installed:

• Flex: A tool for generating lexical analyzers.
• Bison: A parser generator that produces a C program.
• GCC: The GNU Compiler Collection for compiling the C code.

Files

• lexical.l: Contains the rules for lexical analysis.
• syntaxique.y: Defines the grammar for syntax analysis.
• ts.h: Contains functions for managing the symbol table.
• quad.h: Manages the generation and handling of quadruples.

How to Execute

1. Create a commande.bat file with the following content:

   flex lexical.l
   bison -d syntaxique.y
   gcc lex.yy.c syntaxique.tab.c -o projet.exe -lfl -ly
   projet.exe EXAMPLE.txt < EXAMPLE.txt

2. Run the commande.bat file to compile and execute the project. This will:

   • Generate the lexer from lexical.l.
   • Generate the parser from syntaxique.y.
   • Compile the generated C files using gcc.
   • Run the compiled executable projet.exe with EXAMPLE.txt as the input.

Example Usage

To test the compiler, include your source code in EXAMPLE.txt. The output will display the results of the lexical and syntax analysis, along with any intermediate code (quadruples) generated.

Project Structure

• Lexical Analyzer: Tokenizes the input and handles keywords, identifiers, literals, etc.
• Parser: Analyzes the syntax structure according to the grammar rules.
• Symbol Table: Keeps track of all identifiers and their attributes.
• Quadruples: Represents the intermediate code for further compilation phases.
