Stmt-switch

Make-stmt-switch

Basic constructor macro for stmt-switch structures.

Syntax

(make-stmt-switch [:ctrl <ctrl>] 
                  [:body <body>])

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

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

Definition

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

Macro: make-stmt-switch

(defmacro make-stmt-switch (&rest args)
  (std::make-aggregate 'stmt-switch
                       args '((:ctrl) (:body))
                       'make-stmt-switch
                       nil))

Function: stmt-switch

(defun stmt-switch (ctrl body)
  (declare (xargs :guard (and (exprp ctrl) (stmtp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'stmt-switch))
    (declare (ignorable __function__))
    (b* ((ctrl (mbe :logic (expr-fix ctrl) :exec ctrl))
         (body (mbe :logic (stmt-fix body)
                    :exec body)))
      (cons :switch (list ctrl body)))))
