Vl-constint

Change-vl-constint

Modifying constructor for vl-constint structures.

Syntax

(change-vl-constint x 
                    [:origwidth <origwidth>] 
                    [:value <value>] 
                    [:origsign <origsign>] 
                    [:wasunsized <wasunsized>])

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

We construct a new vl-constint 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-constint

(defmacro change-vl-constint (x &rest args)

                         x args
                         '((:origwidth . vl-constint->origwidth)
                           (:value . vl-constint->value)
                           (:origsign . vl-constint->origsign)
                           (:wasunsized . vl-constint->wasunsized))
                         'change-vl-constint
                         'nil))
