Because sincos returns _TWO_ values and the vectorizer does not yet support this. ASAP as the middle-end infrastructure is in place, we can stick vectorized sincos in ix86_veclib* functions. See also [1] and [2], sincos part. Perhaps you could motivate Richi to extend the vectorizer infrastructure ;) [1] http://software.intel.com/en-us/articles/implement-the-short-vector-math-library/ [2] http://developer.amd.com/cpu/Libraries/acml/onlinehelp/Documents/Vector.html#Vector -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40766
