A brainfuck compiler written in Rust, using LLVM

The code uses cargo to build and run the code, and uses the inkwell crate to access the LLVM API.

Inkwell requires you to have LLVM 10 installed on your system to compile this from source. For instructions on how to install LLVM, look here: https://clang.llvm.org/get_started.html

brainfrick-rust requires two requires a source file and a -o OUTPUT_PATH so the compiler knows where to put the compiled code.

brainfrick-rust produces object files, and the compiled code must be linked manually. The easiest way to do this is to run gcc OUTPUT_PATH -o EXECUTABLE_PATH

The samples directory contains a few examples from the Wikipedia page and can be run via cargo run FILENAME -o OUTPUT_PATH, then linking it with gcc as described above

cargo run samples/addition.bf -o tests/addition.o
gcc tests/addition.o -o tests/addition.exe
./tests/addition.exe 
7

cargo run samples/addition.bf -o tests/addition.o
gcc tests/hello_world.o -o tests/hello_world.exe
./tests/hello_world.exe
Hello World!

cargo run samples/ROT13.bf -o tests/ROT13.o
gcc tests/ROT13.o -o tests/ROT13.exe
./tests/ROT13.exe
