CS F363 Compiler Construction

Lexical Analysis

• To run the lexer, ensure you're in the 'Lexical Analysis' directory
• Once in the directory, run the command ./lexer.sh in the terminal
• At this stage, the file needs to be hard-coded into the lexer.l file (this will be fixed in later iterations of the code)

Syntax Analysis

• To run the parser, ensure you're in the 'Syntax Analysis' directory
• Once in the directory, run the command ./parser.sh <test_file.c> in the terminal
• Here, the test_file can be any file with a .c extension. Some working sample test files are given in the same directory

Semantic Analysis

• To run the parser, ensure you're in the 'Semantic Analysis' directory
• Once in the directory, run the command ./parser.sh <test_file.c> in the terminal
• Here, the test_file can be any file with a .c extension. Some working sample test files are given in the same directory
• If the .c file does not contain any errors, it will appropriately generate the Symbol Table for the given program and print it in an output.txt file
  Note: If the .c file contains errors, the Symbol Table will not be generated

Quadruple (Three Address Code) Generation

• To run the parser, ensure you're in the 'TAC' directory
• Once in the directory, run the command ./tac.sh <test_file.c> in the terminal
• Here, the test_file can be any file with a .c extension. Some working sample test files are given in the same directory
• The program will appropriately generate the Three-Address code for the given input file and print it in an output.txt file
