Thanks! Do you know if the Rust compiler is able to pass this information to LLVM somehow?

  It seems it isn't yet: https://github.com/rust-lang/rust/issues/116744 https://github.com/rust-lang/rust/issues/116744

    It does pass this information to LLVM, in the form of the `readonly` attribute. This seems to be a bug in LLVM that does not optimize the function propely, I don't know why.
