--- Comment #18 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
As I outlined in
<https://sourceware.org/ml/libc-alpha/2013-07/msg00444.html>, and as
described in the discussion of accuracy goals in the glibc manual, I don't
think functions such as sin and cos should try to be correctly rounded,
only functions such as crsin and crcos (if added).
