  You probably need to look at http://llvm.org/docs/ExtendingLLVM.html.
Simply put, when you want to extend LLVM IR, say adding a new LLVM
instruction, you have better try to add a intrinsic function [1] which has
the same effect as the instruction you want to add.  

  I don't think they are the same as GCC built-in.
