Instr-load

Make-instr-load

Basic constructor macro for instr-load structures.

Syntax

(make-instr-load [:funct <funct>] 
                 [:rd <rd>] 
                 [:rs1 <rs1>] 
                 [:imm <imm>])

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

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

Definition

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

Macro: make-instr-load

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

Function: instr-load

(defun instr-load (funct rd rs1 imm)
  (declare (xargs :guard (and (load-funct-p funct)
                              (ubyte5p rd)
                              (ubyte5p rs1)
                              (ubyte12p imm))))
  (declare (xargs :guard t))
  (let ((__function__ 'instr-load))
    (declare (ignorable __function__))
    (b* ((funct (mbe :logic (load-funct-fix funct)
                     :exec funct))
         (rd (mbe :logic (ubyte5-fix rd) :exec rd))
         (rs1 (mbe :logic (ubyte5-fix rs1) :exec rs1))
         (imm (mbe :logic (ubyte12-fix imm)
                   :exec imm)))
      (cons :load (list funct rd rs1 imm)))))
