Sounds great.  Thank you!

As to testing AVX, you can by using Intel SDE:

http://software.intel.com/en-us/articles/intel-software-development-emulator/

"This version includes support for SSE4, AES and PCLMULQDQ and the Intel
AVX and AVX2 instructions."

No, you don't have to actually re-test LM in this way - I think the
testing you performed is sufficient, and I did test AVX builds on 7-bit
LM passwords.

I am unaware of an equivalent for XOP, unfortunately.  AMD's SimNow
appears to emulate an entire system only (so is more difficult to use)
and it appears to lack XOP support at this time anyway.
