Vl-union

Change-vl-union

Modifying constructor for vl-union structures.

Syntax

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

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

We construct a new vl-union 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.
