Well, there is ! { dg-require-effective-target fortran_large_real } but I believe that that is insufficient in detecting ppc's use of a double-double representation for its long double. I also don't know if there is an equivalent effective-target to provide the required differentiation. > If this is really not possible here, then I'll prepare an XFAIL > patch, but it's not an ideal solution. It's not a long list if you XFAIL this for all ppc systems. You need something along the lines ! { dg-do run { target { ! { ppc*-*-* } } } }
