Vl-atom

Make-vl-atom

Basic constructor macro for vl-atom structures.

Syntax

(make-vl-atom [:guts <guts>] 
              [:finalwidth <finalwidth>] 
              [:finaltype <finaltype>] 
              [:atts <atts>])

This is the usual way to construct vl-atom structures. It simply conses together a structure with the specified fields.

This macro generates a new vl-atom structure from scratch. See also change-vl-atom, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-atom

(defmacro make-vl-atom (&rest args)
  (std::make-aggregate 'vl-atom
                       args
                       '((:guts)
                         (:finalwidth)
                         (:finaltype)
                         (:atts))
                       'make-vl-atom
                       nil))

Function: vl-atom

(defun vl-atom (guts finalwidth finaltype atts)
 (declare (xargs :guard (and (vl-atomguts-p guts)
                             (maybe-natp finalwidth)

                             (vl-atts-p atts))))

 (let ((__function__ 'vl-atom))
  (declare (ignorable __function__))
  (b* ((guts (mbe :logic (vl-atomguts-fix guts)

       (finaltype (mbe :logic (vl-maybe-exprtype-fix finaltype)
                       :exec finaltype))
       (atts (mbe :logic (vl-atts-fix atts)
                  :exec atts)))
    (cons :atom (std::prod-cons (std::prod-cons guts finalwidth)
                                (std::prod-cons finaltype atts))))))
