Execute LLVM IR code generated from Rust/Python source code

Question

When I generate LLVM IR Code from C++, I can use the console command clang++ -emit-llvm –S test.cpp to get a test.ll file which is the LLVM IR I want.

Answer 1

I can speak of Rust code:

You need to link Rust's std library something like this:

$(LLI) -load /Users/Stanislaw/.rustup/toolchains/stable-x86_64-apple-darwin/lib/libstd-f5a209a9.dylib ./target/debug/jitrust.bc

See the full example of Makefile I use here.

P.S. I would assume that the same goes about Python. You have to also supply libraries which contain this "unreferenced" stuff.
