-   The macro implementation should do two things: first, push onto the
-   stack all the argument registers *not* used for the named
-   arguments, and second, store the size of the data thus pushed into
-   the `int'-valued variable whose name is supplied as the argument
-   PRETEND_SIZE.  The value that you store here will serve as
-   additional offset for setting up the stack frame.
-
-   If the argument NO_RTL is nonzero, it means that the
-   arguments of the function are being analyzed for the second time.
-   This happens for an inline function, which is not actually
-   compiled until the end of the source file.  The macro
-   `SETUP_INCOMING_VARARGS' should not generate any instructions in
