Instr-op

Make-instr-op

Basic constructor macro for instr-op structures.

Syntax

(make-instr-op [:funct <funct>] 
               [:rd <rd>] 
               [:rs1 <rs1>] 
               [:rs2 <rs2>])

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

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

Definition

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

Macro: make-instr-op

(defmacro make-instr-op (&rest args)
  (std::make-aggregate 'instr-op
                       args '((:funct) (:rd) (:rs1) (:rs2))
                       'make-instr-op
                       nil))

Function: instr-op

(defun instr-op (funct rd rs1 rs2)
  (declare (xargs :guard (and (op-funct-p funct)
                              (ubyte5p rd)
                              (ubyte5p rs1)
                              (ubyte5p rs2))))
  (declare (xargs :guard t))
  (let ((__function__ 'instr-op))
    (declare (ignorable __function__))
    (b* ((funct (mbe :logic (op-funct-fix funct)
                     :exec funct))
         (rd (mbe :logic (ubyte5-fix rd) :exec rd))
         (rs1 (mbe :logic (ubyte5-fix rs1) :exec rs1))
         (rs2 (mbe :logic (ubyte5-fix rs2)
                   :exec rs2)))
      (cons :op (list funct rd rs1 rs2)))))
