Vl-assign

Make-vl-assign

Basic constructor macro for vl-assign structures.

Syntax

(make-vl-assign [:lvalue <lvalue>] 
                [:expr <expr>] 
                [:loc <loc>] 
                [:atts <atts>] 
                [:strength <strength>] 
                [:delay <delay>])

This is the usual way to construct vl-assign structures. It simply conses together a structure with the specified fields.

This macro generates a new vl-assign structure from scratch. See also change-vl-assign, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-assign

(defmacro make-vl-assign (&rest args)
  (std::make-aggregate 'vl-assign

                       '((:lvalue)
                         (:expr)
                         (:loc)
                         (:atts)
                         (:strength)
                         (:delay))
                       'make-vl-assign
