Vl-genloop

Make-vl-genloop

Basic constructor macro for vl-genloop structures.

Syntax

(make-vl-genloop [:var <var>] 
                 [:initval <initval>] 
                 [:continue <continue>] 
                 [:nextval <nextval>] 
                 [:body <body>] 
                 [:loc <loc>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-genloop

(defmacro make-vl-genloop (&rest args)
  (std::make-aggregate 'vl-genloop
                       args
                       '((:var)
                         (:initval)
                         (:continue)
                         (:nextval)
                         (:body)
                         (:loc))
                       'make-vl-genloop
                       nil))
