Vl-weirdint

Make-vl-weirdint

Basic constructor macro for vl-weirdint structures.

Syntax

(make-vl-weirdint [:bits <bits>] 
                  [:origsign <origsign>] 
                  [:wasunsized <wasunsized>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-weirdint

(defmacro make-vl-weirdint (&rest args)
  (std::make-aggregate 'vl-weirdint
                       args
                       '((:bits) (:origsign) (:wasunsized))
                       'make-vl-weirdint
                       nil))

Function: vl-weirdint

(defun vl-weirdint (bits origsign wasunsized)
 (declare (xargs :guard (and (vl-bitlist-p bits)
                             (vl-exprsign-p origsign)
                             (booleanp wasunsized))))
 (declare (xargs :guard (consp bits)))
 (let ((__function__ 'vl-weirdint))
  (declare (ignorable __function__))
  (b* ((bits (mbe :logic (vl-bitlist-fix bits)
                  :exec bits))
       (origsign (mbe :logic (vl-exprsign-fix origsign)
                      :exec origsign))
       (wasunsized (mbe :logic (acl2::bool-fix wasunsized)
                        :exec wasunsized)))
   (let ((bits (mbe :logic (vl-bitlist-nonempty-fix bits)
                    :exec bits)))
    (hons :vl-weirdint
          (std::prod-hons bits
                          (std::prod-hons origsign wasunsized)))))))
