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: cpu.rb
    path of file: ./repos/brew/Library/Homebrew/extend/os/mac/hardware
    
    the code of the file until where you have to start completion: module Hardware
  class CPU
 
    
      def ppc_can_run?(arch)
        case arch
        when *PPC_32BIT_ARCHS
          true
        when *PPC_64BIT_ARCHS
          Hardware::CPU.is_64_bit?
        else
          # Intel is never supported
          false
        end
