A goal that is being worked towards is making LLVM thinLTO not just consider clang output but to consider clang-generated LLVM IR together with rustc-generated LLVM IR. This is expected to lead to inlining between C++ and Rust making the FFI layer of C-linkage function calls melt away between C++ and Rust.
