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