arguments at lower addresses, which means we need to
reverse the order compared to how we would normally
treat either big or little-endian. For those arguments
that will wind up in registers, this still works for
HPPA (the only current STACK_GROWSUP target) since the
argument registers are *also* allocated in decreasing
order. If another such target is added, this logic may
have to get more complicated to differentiate between
stack arguments and register arguments. */
