#![feature(coverage_attribute)]
//@ edition: 2021
// Test that coverage instrumentation can gracefully handle functions that end
// up having no relevant spans, without crashing the compiler or causing
// `llvm-cov` to fail.
//
// This was originally a regression test for issues such as #118643 and #118662.
