// 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.
