-/*{{{ Implementing the VARARGS Macros. */
-
-/* This macro offers an alternative to using `__builtin_saveregs' and defining
- the macro `EXPAND_BUILTIN_SAVEREGS'. Use it to store the anonymous register
- arguments into the stack so that all the arguments appear to have been
- passed consecutively on the stack. Once this is done, you 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_ARGS_SIZE. The value that you
- store here will serve as additional offset for setting up the stack frame.
-
- Because you must generate code to push the anonymous arguments at compile
- time without knowing their data types, `SETUP_INCOMING_VARARGS' is only
- useful on machines that have just a single category of argument register and
- use it uniformly for all data types.
-
- If the argument SECOND_TIME 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
- this case. */
