-// FIXME(#79651): "Unexecuted instantiation" errors appear in coverage results,
-// for example:
-//
-// | Unexecuted instantiation: used_crate::used_only_from_bin_crate_generic_function::<_>
-//
-// These notices appear when `llvm-cov` shows instantiations. This may be a
-// default option, but it can be suppressed with:
-//
-// ```shell
-// $ `llvm-cov show --show-instantiations=0 ...`
-// ```
-//
-// The notice is triggered because the function is unused by the library itself,
-// and when the library is compiled, a synthetic function is generated, so
-// unused function coverage can be reported. Coverage can be skipped for unused
-// generic functions with:
-//
-// ```shell
-// $ `rustc -Zunstable-options -C instrument-coverage=except-unused-generics ...`
-// ```
-//
-// Even though this function is used by `uses_crate.rs` (and
-// counted), with substitutions for `T`, those instantiations are only generated
-// when the generic function is actually used (from the binary, not from this
-// library crate). So the test result shows coverage for all instantiated
-// versions and their generic type substitutions, plus the `Unexecuted
-// instantiation` message for the non-substituted version. This is valid, but
-// unfortunately a little confusing.
-//
-// The library crate has its own coverage map, and the only way to show unused
-// coverage of a generic function is to include the generic function in the
-// coverage map, marked as an "unused function". If the library were used by
-// another binary that never used this generic function, then it would be valid
-// to show the unused generic, with unknown substitution (`_`).
-//
-// The alternative is to exclude all generics from being included in the "unused
-// functions" list, which would then omit coverage results for
-// `unused_generic_function<T>()`, below.
