Make-iconst

Basic constructor macro for iconst structures.

Syntax

(make-iconst [:value <value>] 
             [:base <base>] 
             [:unsignedp <unsignedp>] 
             [:length <length>])

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

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

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-iconst

(defmacro make-iconst (&rest args)
  (std::make-aggregate 'iconst
                       args
                       '((:value)
                         (:base)
                         (:unsignedp)
                         (:length))
                       'make-iconst
                       nil))

Function: iconst

(defun iconst (value base unsignedp length)
  (declare (xargs :guard (and (natp value)
                              (iconst-basep base)
                              (booleanp unsignedp)
                              (iconst-lengthp length))))
  (declare (xargs :guard t))
  (let ((__function__ 'iconst))
    (declare (ignorable __function__))
    (b* ((value (mbe :logic (nfix value) :exec value))
         (base (mbe :logic (iconst-base-fix base)
                    :exec base))
         (unsignedp (mbe :logic (acl2::bool-fix unsignedp)
                         :exec unsignedp))
         (length (mbe :logic (iconst-length-fix length)
                      :exec length)))
      (cons :iconst (list (cons 'value value)
                          (cons 'base base)
                          (cons 'unsignedp unsignedp)
                          (cons 'length length))))))
