Sin$c-init

Concrete implementation of strin-init.

Signature

(sin$c-init contents filename sin$c) → sin$c

Arguments

contents — Guard (stringp contents).

filename — Guard (stringp filename).

Definitions and Theorems

Function: sin$c-init

(defun sin$c-init (contents filename sin$c)
  (declare (xargs :stobjs (sin$c)))
  (declare (xargs :guard (and (stringp contents)
                              (stringp filename))))
  (let ((__function__ 'sin$c-init))
    (declare (ignorable __function__))
    (b* ((sin$c (update-sin$c-pos 0 sin$c))
         (sin$c (update-sin$c-line 0 sin$c))
         (sin$c (update-sin$c-col 0 sin$c))
         (sin$c (update-sin$c-file filename sin$c)))
      (mbe :logic (update-sin$c-str contents sin$c)
           :exec
           (if (< (the (integer 0 *) (length contents))
                  (expt 2 60))
               (update-sin$c-str contents sin$c)
             (ec-call (update-sin$c-str contents sin$c)))))))

Theorem: sin-init{correspondence}

(defthm sin-init{correspondence}
  (implies (and (sin$corr sin$c x)
                (stringp contents)
                (stringp filename)
                (strin-p x))
           (sin$corr (sin$c-init contents filename sin$c)
                     (strin-init contents filename x))))
