I'm not aware of either the trig language code generator nor any work to
implement it in LLVM.

You should read these:


If you're unsure of how things are implemented, take a look at how
similar things are done in X86, PowerPC, Alpha or IA64, they all have
SelectionDAG-based instruction selectors (*ISelPattern.cpp).  If that
doesn't clear things up, ask on the list or IRC channel.
