Fenv

Make-fenv

Basic constructor macro for fenv structures.

Syntax

(make-fenv [:constants <constants>] 
           [:curve <curve>])

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

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

Definition

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

Macro: make-fenv

(defmacro make-fenv (&rest args)
  (std::make-aggregate 'fenv
                       args '((:constants) (:curve))
                       'make-fenv
                       nil))

Function: fenv

(defun fenv (constants curve)
  (declare (xargs :guard (and (const-fenvp constants)
                              (curvep curve))))
  (declare (xargs :guard t))
  (let ((__function__ 'fenv))
    (declare (ignorable __function__))
    (b* ((constants (mbe :logic (const-fenv-fix constants)
                         :exec constants))
         (curve (mbe :logic (curve-fix curve)
                     :exec curve)))
      (cons :fenv (list (cons 'constants constants)
                        (cons 'curve curve))))))
