Hello World using LLVM (13) In Rust

Adapted from this article Using LLVM from Rust to generate WebAssembly binaries

Just prints "Hello World" in an executable, currently set up for arm64, but should be straight forward to set up for other architectures

Run (MacOS arm64)

Install LLVM 13

brew install llvm@13

Set LLVM_SYS_130_PREFIX variable

export LLVM_SYS_130_PREFIX=/PATH/TO/LLVM13/VERSION

We can then generate the executable

cargo run

Then run the executable

./main

Which should print "Hello world!"
