Naegleria

A brainfuck compiler written in PHP.

Naegleria fowleri /nəˈɡlɪəriə/ (also known as the "brain-eating amoeba") infects people by entering the body through the nose.

Usage

You can use Naegleria to compile a brainfuck file into AT&T assembly. This can then be assembled using gcc, and executed directly.

$ bin/compile examples/hello.b > hello.s
$ gcc -o hello hello.s
$ ./hello
Hello World!

Platforms

Targets 64-bit x86 on linux, specifically gcc.

Limitations

The compiler uses a fixed-size array of 4000 elements for the cells.

Performance

It's assembly, so probably faster than C.

Benchmarks

Run your own.

Optimizations

This is not (yet) an optimizing compiler.
