Expr-arrsub

Make-expr-arrsub

Basic constructor macro for expr-arrsub structures.

Syntax

(make-expr-arrsub [:arg1 <arg1>] 
                  [:arg2 <arg2>])

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

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

Definition

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

Macro: make-expr-arrsub

(defmacro make-expr-arrsub (&rest args)
  (std::make-aggregate 'expr-arrsub
                       args '((:arg1) (:arg2))
                       'make-expr-arrsub
                       nil))

Function: expr-arrsub

(defun expr-arrsub (arg1 arg2)
  (declare (xargs :guard (and (exprp arg1) (exprp arg2))))
  (declare (xargs :guard t))
  (let ((__function__ 'expr-arrsub))
    (declare (ignorable __function__))
    (b* ((arg1 (mbe :logic (expr-fix arg1) :exec arg1))
         (arg2 (mbe :logic (expr-fix arg2)
                    :exec arg2)))
      (cons :arrsub (list arg1 arg2)))))
