You might also consider using/extending the risu test cases for ppc64 -- individual checks of each insn against a known-good implementation can be easier to track down bugs than trying to figure out why a higher-level test suite like the glibc one has reported a failure, IME. (There are already risu patterns for XSCVDPSP and XSCVDPSPN, so I think that bug at least ought to be found by risu if you run it against the right h/w as known-good reference...) thanks -- PMM
