25| |// Notes:
|
||
|
|
26| |// 1. Compare this program and its coverage results to those of the similar tests
|
||
|
|
27| |// `panic_unwind.rs` and `try_error_result.rs`.
|
||
|
|
28| |// 2. This test confirms the coverage generated when a program includes `TerminatorKind::Abort`.
|
||
|
|
29| |// 3. The test does not invoke the abort. By executing to a successful completion, the coverage
|
||
|
|
30| |// results show where the program did and did not execute.
|
||
|
|
31| |// 4. If the program actually aborted, the coverage counters would not be saved (which "works as
|
||
|
|
32| |// intended"). Coverage results would show no executed coverage regions.
|
||
|
|
33| |// 6. If `should_abort` is `true` and the program aborts, the program exits with a `132` status
|
||
|
|
34| |// (on Linux at least).
