--- Comment #9 from Richard Henderson <rth at gcc dot gnu.org> 2011-02-08 16:17:10 UTC --- I don't think we really want to pursue this further. I had hoped to find a solution that satisfied the older apple compiler -- it is supposed to support altivec after all -- but it remains a mystery what is broken with that compiler.
