You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: iseq_loader_checker.rb
    path of file: ./repos/ruby/tool/lib
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

begin
  require '-test-/iseq_load/iseq_load'
rescue LoadError
end
require 'tempfile'

class RubyVM::InstructionSequence
  def disasm_if_possible
    begin
      self.disasm
    rescue Encoding::CompatibilityError, EncodingError, SecurityError
  
    
  def self.compare_dump_and_load i1, dumper, loader
    dump = dumper.call(i1)
    return i1 unless dump
    i2 = loader.call(dump)

    # compare disassembled result
    d1 = i1.disasm_if_possible
    d2 = i2.disasm_if_possible

    if d1 != d2
      STDERR.puts "expected:"
      STDERR.puts d1
      STDERR.puts "actual:"
      STDERR.puts d2

      t1 = Tempfile.new("expected"); t1.puts d1; t1.close
      t2 = Tempfile.new("actual"); t2.puts d2; t2.close
      system("diff -u #{t1.path} #{t2.path}") # use diff if available
      exit(1)
    end
