AMD indeed still says undefined in their documentation (as of two hours
ago).  I have asked AMD for a clarification, mainly to make sure they
are aware of Intel's documentation change.

(I am not certain about what you doubt.  As I said, I did not check all
2^64 operand values combined all possible bt bit position arguments.  I
believe I have checked all 64-bit x86 processors implementations [two
generations of Core2, NHM and WSM based Core ix, Via Nano, as well as all
Athlon64/Opteron generations).)
