Statement-assign

Make-statement-assign

Basic constructor macro for statement-assign structures.

Syntax

(make-statement-assign [:op <op>] 
                       [:left <left>] 
                       [:right <right>])

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

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

Definition

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

Macro: make-statement-assign

                       args '((:op) (:left) (:right))
                       'make-statement-assign
                       nil))

Function: statement-assign

(defun statement-assign (op left right)
  (declare (xargs :guard (and (asgopp op)
                              (expressionp left)
                              (expressionp right))))
  (declare (xargs :guard t))
  (let ((__function__ 'statement-assign))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (asgop-fix op) :exec op))
         (left (mbe :logic (expression-fix left)
                    :exec left))
         (right (mbe :logic (expression-fix right)
                     :exec right)))
      (cons :assign (list op left right)))))
