used when an argument is passed in multiple locations. The mode of the
of the @code{parallel} should be the mode of the entire argument. The
@code{parallel} holds any number of @code{expr_list} pairs; each one
-describes where part of the argument is passed. In each @code{expr_list},
-the first operand can be either a @code{reg} RTX for the hard register
-in which to pass this part of the argument, or zero to pass the argument
-on the stack. If this operand is a @code{reg}, then the mode indicates
-how large this part of the argument is. The second operand of the
-@code{expr_list} is a @code{const_int} which gives the offset in bytes
-into the entire argument where this part starts.
