Instruction-equal

Make-instruction-equal

Basic constructor macro for instruction-equal structures.

Syntax

(make-instruction-equal [:op <op>] 
                        [:arg1 <arg1>] 
                        [:arg2 <arg2>] 
                        [:into <into>])

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

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

Definition

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

Macro: make-instruction-equal

(defmacro make-instruction-equal (&rest args)
  (std::make-aggregate 'instruction-equal
                       args '((:op) (:arg1) (:arg2) (:into))
                       'make-instruction-equal
                       nil))

Function: instruction-equal

(defun instruction-equal (op arg1 arg2 into)
  (declare (xargs :guard (and (equal-opp op)
                              (operandp arg1)
                              (operandp arg2)
                              (registerp into))))
  (declare (xargs :guard t))
  (let ((__function__ 'instruction-equal))
    (declare (ignorable __function__))
    (b* ((op (mbe :logic (equal-op-fix op) :exec op))
         (arg1 (mbe :logic (operand-fix arg1)
                    :exec arg1))
         (arg2 (mbe :logic (operand-fix arg2)
                    :exec arg2))
         (into (mbe :logic (register-fix into)
                    :exec into)))
      (cons :equal (list op arg1 arg2 into)))))
