Yes (I did not invent it, I tried it because I saw it): gcc.dg/vect/vect-(82|83)_64.c for instance. /* { dg-do run { target { { powerpc*-*-* && lp64 } && powerpc_altivec_ok } } } */ /* { dg-do compile { target { { powerpc*-*-* && ilp32 } && powerpc_altivec_ok } } } */ /* { dg-options "-O2 -ftree-vectorize -mpowerpc64 -fdump-tree-vect-stats -maltivec" } */ > I suspect that is an unsupported combination. Now you asked the question, the test is not run on powerpc-apple-darwin9 with -m64. Could you try to put the 'dg-do compile' line before the 'dg-do run' one?
