#![allow(dead_code, unreachable_code)]

//@ edition: 2021

// Regression test for #93054: Functions using uninhabited types often only have a single,
|
|
// unreachable basic block which doesn't get instrumented. This should not cause llvm-cov to fail.
|
|
// Since these kinds functions can't be invoked anyway, it's ok to not have coverage data for them.
