This repository is an example of linking, and using LLVM from with the Rust language. The only reference examples are within the Rust compiler's source code, which can be very cryptic given the amount of extra context there is.
Linking LLVM with Rust is dead simple. I really mean it. You simply need to link against the rustc (dynamic) library, which contains the Rust compiler, and LLVM Rust bindings. This library already has the LLVM library staticly linked against it.
Fetch this repo:
git clone git@github.com:TheHydroImpulse/rust-llvm-example.git
And build and run it:
make run
This will create a binary within the ./bin/ directory called rustllvm.
By default, we simply create an empty Context, Builder and Module. We finally print the contents of the module (module->dump() in C++ terms) to stderr.
You can start emitting LLVM IR from within the context and module, afterwhich you should see more than just:
; ModuleID = 'mod1'
As an output.
