   22|       |// Notes:
   23|       |//   1. Compare this program and its coverage results to those of the very similar test
   24|       |//      `panic_unwind.rs`, and similar tests `abort.rs` and `try_error_result.rs`.
   25|       |//   2. This test confirms the coverage generated when a program passes or fails an `assert!()` or
   26|       |//      related `assert_*!()` macro.
   27|       |//   3. Notably, the `assert` macros *do not* generate `TerminatorKind::Assert`. The macros produce
   28|       |//      conditional expressions, `TerminatorKind::SwitchInt` branches, and a possible call to
   29|       |//      `begin_panic_fmt()` (that begins a panic unwind, if the assertion test fails).
   30|       |//   4. `TerminatoKind::Assert` is, however, also present in the MIR generated for this test
   31|       |//      (and in many other coverage tests). The `Assert` terminator is typically generated by the
   32|       |//      Rust compiler to check for runtime failures, such as numeric overflows.
