   5 * This is used to ensure the compiler did actually allocate the register we
   6 * asked it for some inline assembly sequences.  Apparently we can't trust
   7 * the compiler from one version to another so a bit of paranoia won't hurt.
   8 * This string is meant to be concatenated with the inline asm string and
   9 * will cause compilation to stop on mismatch.
  10 * (for details, see gcc PR 15089)
