Range

Change-range

Modifying constructor for range structures.

Syntax

(change-range x 
              [:lsb <lsb>] 
              [:width <width>])

This is an often useful alternative to make-range.

We construct a new range 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.
