Vl-letdecl

Change-vl-letdecl

Modifying constructor for vl-letdecl structures.

Syntax

(change-vl-letdecl x 
                   [:name <name>] 
                   [:portdecls <portdecls>] 
                   [:expr <expr>] 
                   [:atts <atts>] 
                   [:loc <loc>])

This is an often useful alternative to make-vl-letdecl.

We construct a new vl-letdecl structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by defprod.

Macro: change-vl-letdecl

(defmacro change-vl-letdecl (x &rest args)
  (std::change-aggregate 'vl-letdecl
                         x args
                         '((:name . vl-letdecl->name)
                           (:portdecls . vl-letdecl->portdecls)
                           (:expr . vl-letdecl->expr)
                           (:atts . vl-letdecl->atts)
                           (:loc . vl-letdecl->loc))
                         'change-vl-letdecl
                         'nil))
