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