# branflakes

Yet another x86_64 optimising Brainf*ck JIT compiler. It's very fast, and buggy.

### Performance:

Performance is significantly better than a dumb interpreter, but still far from the best JITs.

### Issues:

- Doesn't work properly with some programs (notably hanoi.b).

- Insufficient bounds checks - a malicious program could overwrite arbitrary memory locations.

- The code is poorly written (I don't really know C *or* x86 assembly)

### TODO:

-  More optimisations.

-  The `,` instruction.
