...n compiler team, is interested in representing Fortran alias information in LLVM IR. We use the XL Fortran frontend to emit LLVM IR that includes alias information to feed to the LLVM in order to create object files. For the Fortran alias representation in LLVM IR, we considered both TBAA and ScopeAlias/NoAlias metadata approaches, we think that the ScopeAlias/NoAlias metadata is more appropriate for refined alias information for Fortran. The XL Fortran frontend emits the alias info in terms of what other symbols that a symbol alias to. We experiment a scheme that represents the alias relat...
