Instruction-hash

Make-instruction-hash

Basic constructor macro for instruction-hash structures.

Syntax

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

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

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

Definition

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

Macro: make-instruction-hash

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

Function: instruction-hash

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