Dorit, I only have access to Darwin PPC at -m64 and x86_64. However I have only been directly testing Darwin PPC at -m64 and relying on the gcc-testresults mailing list archive for the rest of the architectures. Perhaps someone else here can provide a dump file generated by -fdump-tree-vect-details on ia64 for gfortran.dg/vect/vect-5.f90. Jack ps for now I guess we can just adjust the test along these lines...
