mismatched_target_os false negative when using the cfg macro instead of the attribute. #7839
Description
Lint name: mismatched_target_os
I tried this code:
fn main() {
// Clippy throws error
//#[cfg(linux)]
//println!("Hello, Linux!");
// Clippy doesn't care
if cfg!(linux) {
println!("Hello, Linux!");
}
}I expected to see the error operating system used in target family position here like you would see if you used the attribute #[cfg(linux)]
Instead, clippy doesn't give any error.
