#![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.
