Any news here? As noted in
<http://sourceware.org/ml/libc-alpha/2012-02/msg00578.html> I'd like to
see incremental progress here - some cases fixed, with testcases added,
even if not all cases are fixed (eventually we should have reasonably
accurate results for large arguments for all of sin, cos, sincos, tan, for
all argument types, with associated testcases). That would then provide a
basis for other people to fix the long double version on top of fixes for
other types, for example.
Given the use of sincos in other functions, having fixes for sincos is
important to be able to add tests for large inputs to various other
functions (in particular, fixing the Bessel function TLOSS issues).
