Vl-pattern

Make-vl-pattern

Basic constructor macro for vl-pattern structures.

Syntax

(make-vl-pattern [:pat <pat>] 
                 [:pattype <pattype>] 
                 [:atts <atts>])

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

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

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-pattern

(defmacro make-vl-pattern (&rest args)
  (std::make-aggregate 'vl-pattern
                       args '((:pat) (:pattype) (:atts))
                       'make-vl-pattern
                       nil))

Function: vl-pattern

(defun vl-pattern (pat pattype atts)
  (declare (xargs :guard (and (vl-assignpat-p pat)
                              (vl-maybe-datatype-p pattype)
                              (vl-atts-p atts))))
  (declare (xargs :guard t))
  (let ((__function__ 'vl-pattern))
    (declare (ignorable __function__))
    (b* ((pat (mbe :logic (vl-assignpat-fix pat)
                   :exec pat))
         (pattype (mbe :logic (vl-maybe-datatype-fix pattype)
                       :exec pattype))
         (atts (mbe :logic (vl-atts-fix atts)
                    :exec atts)))
      (cons :vl-pattern
            (std::prod-cons pat (std::prod-cons pattype atts))))))
