//@ edition: 2021
// If the span extractor can't find any relevant spans for a function,
// but the function contains coverage span-marker statements (e.g. inserted
// for `if !`), coverage codegen may think that it is instrumented and
// consequently complain that it has no spans.
//
// Regression test for <https://github.com/rust-lang/rust/issues/118850>,
// "A used function should have had coverage mapping data but did not".
