--- Comment #16 from Iain Sandoe <iains at gcc dot gnu.org> --- well.. given the amount of time that's passed - perhaps we'll only get a fix for ld64 if we do it ourselves... What about xfail-run-if - to reduce test noise, and then when (if?) ld64 gets fixed it will "xpass" alerting us to the change?
