Expression-sum-test

Make-expression-sum-test

Basic constructor macro for expression-sum-test structures.

Syntax

(make-expression-sum-test [:type <type>] 
                          [:target <target>] 
                          [:alternative <alternative>])

This is the usual way to construct expression-sum-test structures. It simply conses together a structure with the specified fields.

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

Definition

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

Macro: make-expression-sum-test

(defmacro make-expression-sum-test (&rest args)
  (std::make-aggregate 'expression-sum-test
                       args '((:type) (:target) (:alternative))
                       'make-expression-sum-test
                       nil))

Function: expression-sum-test

(defun expression-sum-test (type target alternative)
  (declare (xargs :guard (and (identifierp type)
                              (expressionp target)
                              (identifierp alternative))))
  (declare (xargs :guard t))
  (let ((__function__ 'expression-sum-test))
    (declare (ignorable __function__))
    (b* ((type (mbe :logic (identifier-fix type)
                    :exec type))
         (target (mbe :logic (expression-fix target)
                      :exec target))
         (alternative (mbe :logic (identifier-fix alternative)
                           :exec alternative)))
      (cons :sum-test (list type target alternative)))))
