LLVM RUST Library

[mananabdul]

Hi! I want to write an LLVM pass for RUST that map a variable attribute and something like that. Does rust provide any library with documentation that allows me to write LLVM pass in Rust not in C?

You could use bindgen to create Rust FFI bindings for any random LLVM version. The alternative is writing those bindings by hand, but I don’t recommend that unless you have a couple of weeks to spare.

As an aside: LLVM is written in C++, not C.

llvm-sys are the community maintained straight bindings to LLVM’s C API.

How extensive are those bindings? Enough for codegen from a university-course level compiler? Or are the bindings focused on other things, like calling the optimizer, the backend and so on - instead of codegen?

(In that case, maybe I can make codegen happen on my end, and invoke the optimizer and backend from the bindings )

Regardless of Rust, IMHO LLVM’s C API is awfully incomplete. For any real work sooner or later you’ll end up needing to use the C++ API.
