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

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,

arguments. The arguments MODE and TYPE describe the last named

argument--its machine mode and its data type as a tree node.

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.

arguments of the function are being analyzed for the second time.
