Vl-randomqualifier-p

Random qualifiers that can be put on struct or union members.

This is an ordinary defenum.

Function: vl-randomqualifier-p

(defun vl-randomqualifier-p (x)
  (declare (xargs :guard t))
  (or (eq x 'nil)
      (eq x ':vl-rand)
      (eq x ':vl-randc)))

Theorem: type-when-vl-randomqualifier-p

(defthm type-when-vl-randomqualifier-p
  (implies (vl-randomqualifier-p x)
           (if (if (symbolp x)
                   (if (not (equal x 't))
                       (not (equal x 'nil))
                     'nil)
                 'nil)
