| // Issue #33540 |
| // We previously used to generate a 3-armed boolean `SwitchInt` in the |
| // MIR of the function `foo` below. #33583 changed rustc to |
| // generate an `If` terminator instead. This test is to just ensure |
| // sanity in that we generate an if-else chain giving the correct |
| // results. |
