Get the label field from a svtv*-phase.
(svtv*-phase->label x) → label
This is an ordinary field accessor created by defprod.
Function:
(defun svtv*-phase->label$inline (x) (declare (xargs :guard (svtv*-phase-p x))) (declare (xargs :guard t)) (let ((__function__ 'svtv*-phase->label)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (acl2::symbol-fix (std::da-nth 0 x))) :exec (std::da-nth 0 x))))
