+// run-pass
+// 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.

+        (false, _) => 0,
+        (_, false) => 1,
+        (true, true) => 2
+    }
