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