Vl-gencase

Make-vl-gencase

Basic constructor macro for vl-gencase structures.

Syntax

(make-vl-gencase [:test <test>] 
                 [:cases <cases>] 
                 [:default <default>] 
                 [:loc <loc>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-gencase

(defmacro make-vl-gencase (&rest args)
  (std::make-aggregate 'vl-gencase
                       args
                       '((:test) (:cases) (:default) (:loc))
                       'make-vl-gencase
                       nil))

Function: vl-gencase

(defun vl-gencase (test cases default loc)
 (declare (xargs :guard (and (vl-expr-p test)
                             (vl-gencaselist-p cases)
                             (vl-genelement-p default)
                             (vl-location-p loc))))
 (declare (xargs :guard t))
 (let ((__function__ 'vl-gencase))
  (declare (ignorable __function__))
  (b* ((test (mbe :logic (vl-expr-fix test)
                  :exec test))
       (cases (mbe :logic (vl-gencaselist-fix cases)
                   :exec cases))
       (default (mbe :logic (vl-genelement-fix default)
                     :exec default))
       (loc (mbe :logic (vl-location-fix loc)
                 :exec loc)))
   (cons
       :vl-gencase (std::prod-cons (std::prod-cons test cases)
                                   (std::prod-cons default loc))))))
