Get the tail field from a rsh-of-concat-table.
(rsh-of-concat-table->tail x) → tail
This is an ordinary field accessor created by defprod.
Function:
(defun rsh-of-concat-table->tail$inline (x) (declare (xargs :guard (rsh-of-concat-table-p x))) (declare (xargs :guard t)) (let ((__function__ 'rsh-of-concat-table->tail)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (svex-fix (cdr (std::da-nth 2 x)))) :exec (cdr (std::da-nth 2 x)))))
