Get the hold field from a svtv*-input.
(svtv*-input->hold x) → hold
This is an ordinary field accessor created by defprod.
Function:
(defun svtv*-input->hold$inline (x) (declare (xargs :guard (svtv*-input-p x))) (declare (xargs :guard t)) (let ((__function__ 'svtv*-input->hold)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (nfix (std::da-nth 2 x))) :exec (std::da-nth 2 x))))
