Vl-struct

Change-vl-struct

Modifying constructor for vl-struct structures.

Syntax

(change-vl-struct x 
                  [:packedp <packedp>] 
                  [:signedp <signedp>] 
                  [:members <members>] 
                  [:pdims <pdims>] 
                  [:udims <udims>])

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

We construct a new vl-struct 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-struct

(defmacro change-vl-struct (x &rest args)
  (std::change-aggregate 'vl-struct
                         x args
                         '((:packedp . vl-struct->packedp)
                           (:signedp . vl-struct->signedp)
                           (:members . vl-struct->members)
                           (:pdims . vl-struct->pdims)
                           (:udims . vl-struct->udims))
                         'change-vl-struct
                         'remake-vl-struct))
