Yes. (Long-term if the MPC performance issues for inverse trig and
hyperbolic functions get fixed it will be possible to move these tests to
auto-libm-test-in and probably generate more tests to make the ulps more
accurately reflect the maximum errors of the functions, in which case
there may be less dependence on the processor.)
