-/* This macro offers an alternative
- to using `__builtin_saveregs' and defining the macro
- `EXPAND_BUILTIN_SAVEREGS'. Use it to store the anonymous register

- can use the standard implementation of varargs that works for
- machines that pass all their arguments on the stack.
-
- The argument ARGS_SO_FAR is the `CUMULATIVE_ARGS' data structure,
- containing the values that obtain after processing of the named
- arguments. The arguments MODE and TYPE describe the last named
- argument--its machine mode and its data type as a tree node.
-
- 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
