α-lang Compiler

What's its purpose?

This compiler was developed as a project for the CS-340 course of the Computer Science Department of the University of Crete.

Learning goals

1. Lexical Analysis using Flex
2. Syntax Analysis using Bison
3. Intermediate code generation using Syntax Directed Translation
4. Target code generation

Using the compiler

How to build the project

Simply run make or make all in order to compile the α-compiler and produce the alang executable.

How to compile an α (alpha) program

To compile your Alpha (.asc) program, simply run ./alang [path-to-file.asc] [optional -d]. This command will compile the program and generate the binary file to be passed to the Alpha virtual machine. If you want to see the SymbolTable entries, Quads, Constants Tables & Target code information that are generated by the compiler, just add the -d flag after the source file's path.

Sidenotes

You can also perform the steps specified by make all one by one. Simply run make flex in order to generate the lexical analyzer (scanner.c file), make bison to generate the syntax parser (parser.c/h file), make tcode_gen to create the target code generator and lastly, make comp in order to compile all the required source files and link them together to produce the final alang executable.
