--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We already disable it rather liberally on AIX:
// { dg-xfail-run-if "AIX long double" { powerpc-ibm-aix* } }
Maybe we should split the long double parts into a separate file and just xfail
that on affected targets, so the rest of the file runs everywhere.
