Expression-binary

Make-expression-binary

Basic constructor macro for expression-binary structures.

Syntax

(make-expression-binary [:op <op>] 
                        [:arg1 <arg1>] 
                        [:arg2 <arg2>])

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

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

Definition

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

Macro: make-expression-binary

(defmacro make-expression-binary (&rest args)
  (std::make-aggregate 'expression-binary
                       args '((:op) (:arg1) (:arg2))
                       'make-expression-binary
                       nil))

Function: expression-binary

(defun expression-binary (op arg1 arg2)
  (declare (xargs :guard (and (binopp op)
                              (expressionp arg1)
                              (expressionp arg2))))
  (declare (xargs :guard t))
  (let ((__function__ 'expression-binary))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (binop-fix op) :exec op))
         (arg1 (mbe :logic (expression-fix arg1)
                    :exec arg1))
         (arg2 (mbe :logic (expression-fix arg2)
                    :exec arg2)))
      (cons :binary (list op arg1 arg2)))))
