Vl-unary

Make-vl-unary

Basic constructor macro for vl-unary structures.

Syntax

(make-vl-unary [:op <op>] 
               [:arg <arg>] 
               [:atts <atts>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-unary

(defmacro make-vl-unary (&rest args)
  (std::make-aggregate 'vl-unary
                       args '((:op) (:arg) (:atts))
                       'make-vl-unary
                       nil))

Function: vl-unary

(defun vl-unary (op arg atts)
 (declare (xargs :guard (and (vl-unaryop-p op)
                             (vl-expr-p arg)
                             (vl-atts-p atts))))
 (declare (xargs :guard t))
 (let ((__function__ 'vl-unary))
  (declare (ignorable __function__))
  (b* ((op (mbe :logic (vl-unaryop-fix op)
                :exec op))
       (arg (mbe :logic (vl-expr-fix arg)
                 :exec arg))
       (atts (mbe :logic (vl-atts-fix atts)
                  :exec atts)))
   (cons :vl-unary (std::prod-cons op (std::prod-cons arg atts))))))
