| ; When we promote two arguments in a single function with different types, |
| ; before the fix, we used the same tag for the newly-created two loads. |
| ; This testing case makes sure that we correctly transfer the tbaa tags from the |
| ; original loads to the newly-created loads when promoting pointer arguments. |
