The builtins get declared in the

  GCC_XML/Support/GCC/4.2/gccxml_builtins.h

file (the above is its location in the gccxml source tree, there is one
in the install tree too).

It seems several builtins are missing from that file but no one has hit
code that needs them until now.  You can add the forward declarations
for the builtins.  In order to learn the signatures of the builtins,
compile this:

template <typename T> void f(T*);
int main()
{
  f(&__builtin_ia32_emms);
  f(&__builtin_ia32_packsswb);
  //...
  return 0;
}

and look at the linker errors.

I can do this eventually, but I won't be able to get to it for a while.
 If you manage to add all the signatures, I'll be happy to accept a patch.
