These tests deliberately use non-standard formatting, so that the line execution counts reported by `llvm-cov` reveal additional information about where code regions begin and end.

LL| |// ISSUE(77553): Originally, this test had `Err(1)` on line 22 (instead of `Ok(())`) and
|
|
LL| |// `std::process::exit(2)` on line 26 (instead of `Err(1)`); and this worked as expected on Linux
|
|
LL| |// and MacOS. But on Windows (MSVC, at least), the call to `std::process::exit()` exits the program
|
|
LL| |// without saving the InstrProf coverage counters. The use of `std::process:exit()` is not critical
|
|
LL| |// to the coverage test for early returns, but this is a limitation that should be fixed.
