Instruction-unary

Make-instruction-unary

Basic constructor macro for instruction-unary structures.

Syntax

(make-instruction-unary [:op <op>] 
                        [:arg <arg>] 
                        [:into <into>])

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

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

Definition

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

Macro: make-instruction-unary

(defmacro make-instruction-unary (&rest args)
  (std::make-aggregate 'instruction-unary
                       args '((:op) (:arg) (:into))
                       'make-instruction-unary
                       nil))

Function: instruction-unary

(defun instruction-unary (op arg into)
  (declare (xargs :guard (and (unary-opp op)
                              (operandp arg)
                              (registerp into))))
  (declare (xargs :guard t))
  (let ((__function__ 'instruction-unary))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (unary-op-fix op) :exec op))
         (arg (mbe :logic (operand-fix arg)
                   :exec arg))
         (into (mbe :logic (register-fix into)
                    :exec into)))
      (cons :unary (list op arg into)))))
