[Bug math/14412] Removal of sysdeps/x86_64/fpu/s_sincos.S causes regressions


http://sourceware.org/bugzilla/show_bug.cgi?id=14412

--- Comment #11 from Rich Felker <bugdal at aerifal dot cx> 2013-04-25 23:58:19 UTC ---
Carlos, as I noted above, the horrible slowness seems to be coming not from the
correct algorithm but from the silly use of feraiseexcept to raise exceptions.
Fixing this should get the performance back at least close to what it was
before when the function was broken.
