Arrange for dejagnu to add the options that enable the sqrt insn, if one is available, and to skip the test otherwise. H-P, this *should* obviate the mmix-specific dg-skip-if. Would it be easy for you to confirm that this is the case and, if so, drop it? This was regstrapped on x86_64-linux-gnu, tested with a cross to a ppc64-vxworks7r2 configured for a cpu that doesn't have fsqrt enabled, and I'm now also regstrapping on ppc64-linux-gnu just to be sure.
