# MazuCC

MazuCC is a minimalist C compiler with x86_64 code generation.

It is intended to support partial C99 language features while keeping the code

as small and simple as possible.

## Build

Run make to build:

```shell

$ make

```

MazuCC comes with unit tests. To run the tests, give "check" as an argument:

```shell

$ make check

```

MazuCC is known to work on both GNU/Linux and macOS.

Use MazuCC to compile C source:

```shell

$ ./mzcc  sample/nqueen.c

```

Alternatively, MazuCC accepts the stream from standard input. The equivalent

 form for the above command is:

 ```shell

 $ cat sample/nqueen.c | ./mzcc -

 ```

You will get the generated x86_64 assembly in AT&T syntax. The output can be

assembled and linked into a valid executable:

```shell

$ ./mzcc -o sample/nqueen.s sample/nqueen.c

$ gcc -no-pie -o sample/nqueen sample/nqueen.s

```

If MazuCC is compiled and executed on macOS, the above argument `-no-pie`

should be eliminated.

Reference output of MazuCC-compiled `sample/nqueen`:

```

Q . . . . . . .

. . . . Q . . .

. . . . . . . Q

. . . . . Q . .

. . Q . . . . .

. . . . . . Q .

. Q . . . . . .

. . . Q . . . .

```

Alternatively, you can dump internal abstract syntax tree:

```shell

echo 'struct {int x; char y; struct { int t; } z; } a;' | ./mzcc --dump-ast -

```

The expected output in S-expression form:

```

(decl (struct (int)

              (char)

              ((struct (int)))) a)

```
