Decl

Make-decl

Basic constructor macro for decl structures.

Syntax

(make-decl [:name <name>] 
           [:type <type>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-decl

(defmacro make-decl (&rest args)
  (std::make-aggregate 'decl
                       args '((:name) (:type make-hint-pair))
                       'make-decl
                       nil))

Function: decl

(defun decl (name type)
  (declare (xargs :guard (and (symbolp name)
                              (hint-pair-p type))))
  (declare (xargs :guard (symbolp (hint-pair->thm type))))
  (let ((acl2::__function__ 'decl))
    (declare (ignorable acl2::__function__))
    (b* ((name (mbe :logic (symbol-fix name)
                    :exec name))
         (type (mbe :logic (hint-pair-fix type)
                    :exec type)))
      (let ((type (mbe :logic (decl->type-reqfix type)
                       :exec type)))
        (list (cons 'name name)
              (cons 'type type))))))
