# GCC Brainfuck

A GCC frontend for the brainfuck programming language.

## Compile the frontend

To compile the Brainfuck frontend, the GCC source code is needed in

addition to the Brainfuck frontend specific files:

```

$ git clone https://github.com/giuseppe/gccbrainfuck.git

$ git clone --depth 1 git://gcc.gnu.org/git/gcc.git

$ ln -s $(pwd)/gccbrainfuck gcc/gcc/brainfuck

```

Once the `gcc/brainfuck` directory is in place, we can compile GCC with

the brainfuck frontend enabled, the GCC build does not allow

`$buildir` to be the same as `$srcdir`, so we will do that in a

`build` subdirectory, even though it could be any other directory.

Compiling GCC can take quite a while, so you can enjoy a coffee while

you are waiting for it.

```

$ mkdir gcc/build

$ cd gcc/build

$ ../configure --enable-languages=brainfuck --disable-multilib

$ make -j $(nproc)

```

Install the files in `build/sysroot`

```

$ make install DESTDIR=sysroot

```

## Compile a Brainfuck "Hello World" program

Now we can compile a simple program written in Brainfuck:

```

$ cat > /tmp/helloworld.bf <++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>

---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.

EOF

$ PATH=$(pwd)/sysroot/usr/local/bin:$PATH gcc helloworld.bf -o helloworld

$ ./helloworld

Hello World!

```
