Ok now that makes more sense to me. So in order to make this move forward I would suggest to use the newly created executable only for the alias analysis tests and `flang/test/Fir/OpenACC/openacc-mappable.fir` so that we modify less file. Ultimately would should find a way to have a single executable but that might require more time.
