C interpreter that interprets itself.
How to Run the Code
xc.c is the original one and
xc-tutor.c is the one that I make for
the tutorial step by step.
gcc -o xc xc.c ./xc hello.c ./xc -s hello.c ./xc xc.c hello.c ./xc xc.c xc.c hello.c
This project is inspired by c4 and is largely based on it.
However, I rewrote them all to make it more understandable and help myself to understand it.
Despite the complexity we saw in books about compiler design, writing one is not that hard. You don't need that much theory though they will help for better understanding the logic behind the code.
Also I write a series of article about how this compiler is built under directory
There is also a chinese version in my blog.
