An (unusual) case I've found it useful for is doing LTO across boundaries with other languages whose compilers use LLVM. I've used it to enable inlining of C++ methods called from Rust (the C++ code in question was V8).

This seems super interesting, I am currently looking at building the whole mingw-w64 crt as LTO libs.

I wonder if this would be applicable with that in combination with gcc-rs.

Disclaimer: I'm also on that rust hype train :)
