As a fun weekend project I wanted to follow along with the tutorial at https://llvm.org/docs/tutorial/index.html but I noticed the API in in C++ so it wouldn't be possible to do this in Pascal without at least some plain C API.

How did Free Pascal/Jonas accomplish this in the LLVM backend?

Afaik there's also a C binding (or at least there used to be one).

FPC generates LLVM IR which is then compiled using clang. It does not link to the LLVM libraries in any way.

There is some c bindings but they seem incomplete, or at least I couldn't figure out how to follow the tutorial using what was provided there.

That's what I thought but that's certainly beyond the scope of what I could do. :)
