Brainfuck

Brainfuck is an esoteric programming language. Its source code consists only of 8 characters. Here is an example of a simple brainfuck program which prints hello world to stdout:

++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.

Usage

Basic usage compiles the source to LLVM and runs it with the LLVM JIT compiler.

$ brainfuck hello.bf
Hello World!

To generate an object file as output, use the -c flag. It will need to be linked against libc.

$ brainfuck -c hello.bf
$ ls
hello.bf  hello.o

To interpret the source directly without LLVM, use the -i flag. This is much slower than the other options.

$ brainfuck -i hello.bf
Hello World!

See the help command for additional flags and usage information.

$ brainfuck --help
