Schar-format

Make-schar-format

Basic constructor macro for schar-format structures.

Syntax

(make-schar-format [:signed <signed>] 
                   [:trap <trap>])

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

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

Definition

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

                       'make-schar-format
                       nil))

Function: schar-format

(defun schar-format (signed trap)
  (declare (xargs :guard (and (signed-formatp signed)
                              (booleanp trap))))
  (declare (xargs :guard t))
  (let ((__function__ 'schar-format))
    (declare (ignorable __function__))
    (b* ((signed (mbe :logic (signed-format-fix signed)
                      :exec signed))
         (trap (mbe :logic (acl2::bool-fix trap)
                    :exec trap)))
      (list (cons 'signed signed)
            (cons 'trap trap)))))
