 <h5>Arguments:</h5>
 
-The first argument is a pointer to a <tt>va_list</tt> element to initialize.
-The second argument is required to be the last LLVM argument before the

 <h5>Semantics:</h5>
 
 The '<tt>llvm.va_start</tt>' intrinsic works just like the <tt>va_start</tt>
 macro available in C.  In a target-dependent way, it initializes the
-<tt>va_list</tt> element the first argument points to, so that the next call to
-<tt>va_arg</tt> will produce the first variable argument passed to the
-function.<p>

+Unlike the C <tt>va_start</tt> macro, this intrinsic does not need to know the
+last argument of the function, the compiler can figure that out.<p>
