  excuse me, I am not familiar with arm assemble code, so can not give more information

  but at least for me, it seems your patch is more precious, and also welcomed by compiler.
  and I don't think your patch make the code "a more complex":
    the reason is:
    "keeping code simple and clear" is for readers and debuggers, not for writers.
    I prefer to write more code to let readers and debuggers easy understand.
      (if it has minor negative effect with performance)

  thanks.
