I have forgotten to mention that I did some (quick) profiling: cexp seens trivially implemented. It calls sin, cos and exp + the ABI problem mentionned by Andrew. It seems that any inplementation of cexp calling sin and cos would at best lead to a draw and more likely to a regression in timing. Now I cannot rule out that on some platforms cexp is implemented in a clever way, using some kind of sincos alrgorithm (this is what I would like to know). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31249
