Instance Method Details

#generate_sled(length, opts) ⇒ Object

Stub method for generating a sled with the provided arguments. Derived Nop implementations must supply a length and can supply one or more of the following options:

- Random (true/false)
  Indicates that the caller desires random NOPs (if supported).
- SaveRegisters (array)
  The list of registers that should not be clobbered by the NOP
  generator.
- BadChars (string)
  The list of characters that should be avoided by the NOP
  generator.

  return nil
end

#nop_repeat_threshold ⇒ Object

Default repetition threshold when finding nop characters.
