Vl-propif

Change-vl-propif

Modifying constructor for vl-propif structures.

Syntax

(change-vl-propif x 
                  [:condition <condition>] 
                  [:then <then>] 
                  [:else <else>])

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

We construct a new vl-propif 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.

                           (:then . vl-propif->then)
                           (:else . vl-propif->else))
