Vl-alias

Make-vl-alias

Basic constructor macro for vl-alias structures.

Syntax

(make-vl-alias [:lhs <lhs>] 
               [:rhs <rhs>] 
               [:atts <atts>] 
               [:loc <loc>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-alias

(defmacro make-vl-alias (&rest args)
  (std::make-aggregate 'vl-alias
                       args '((:lhs) (:rhs) (:atts) (:loc))
                       'make-vl-alias
                       nil))

Function: vl-alias

(defun vl-alias (lhs rhs atts loc)
  (declare (xargs :guard (and (vl-expr-p lhs)
                              (vl-expr-p rhs)
                              (vl-atts-p atts)
                              (vl-location-p loc))))
  (declare (xargs :guard t))
  (let ((__function__ 'vl-alias))
    (declare (ignorable __function__))
    (b* ((lhs (mbe :logic (vl-expr-fix lhs)
                   :exec lhs))
         (rhs (mbe :logic (vl-expr-fix rhs)
                   :exec rhs))
         (atts (mbe :logic (vl-atts-fix atts)
                    :exec atts))
         (loc (mbe :logic (vl-location-fix loc)
                   :exec loc)))
      (cons :vl-alias (std::prod-cons (std::prod-cons lhs rhs)
                                      (std::prod-cons atts loc))))))
