Description
I tried this code:
fn main() {
println!("hello world\n");
}
And I compile with rustc --verbose ./main.rs I get no output.
I expected to see this happen: I'd expect something like clang's output where it shows me what linker is used, the include paths etc...
Instead, this happened: nothing.

Research direction
Start by reproducing the behavior with rustc --verbose ./main.rs and inspect the compiler's --verbose argument handling. Compare the intended output with clang's linker and include-path information; done means the flag produces useful compilation details without changing normal compilation behavior.
