CCompiler

C Compiler to Linux x64 assembly and to LaserLang written in Java.

About

This is a simple c compiler written in Java. Based on the blog series Writing a C Compiler by Nora Sandler. It currently supports a very small subset of C:

• Functions
• Local and Global variables
• All different types of binary/unary math and logic operators
• Flow control (Ifs, Loops)
• Integer types only (The return of void functions is also int for now)

The code quality is not the best, this is an exercise about learning how compilers work.

LaserLang

There is also an option to compile to the esoteric language LaserLang, the option is a boolean variable in the main function. When compiling for LaserLang, you can use the following functions for I/O:

int putchar(int chr);
int putint(int i);
int getint();

• Note: You must declare the IO functions for them to be included in the generated code.

Usage

Compile the source, and then

java -jar CCompiler.jar filename.c

Use the -d flag for debug output.
