About

This is a compiler for a c-like-language.

The early version of the code was based on 9cc which is explained in web based tutorial [低レイヤを知りたい人のためのCコンパイラ作成入門](https://www.sigbus.info/compilerbook\) by Rui Ueyama.

Now the large part of the code has been diverted from the original 9cc.

What does it do?

Not much yet.

Basic codes like below can be compiled to assembly code. (print() is defined separately. Full code is in program/fibonacci.c)

int main() {
  int i;
  int d, e, f;
  d = 0;
  e = 1;
  f = 1;
  for(i = 0; i < 11; i = i + 1) {
    print(d);
    f = d + e;
    d = e;
    e = f;
  }
  putchar(10);
  0;
}

This code write fibonacci seriese to the console, like below.

0 1 1 2 3 5 8 13 21 34 55
