Yeah, my totally infallible memory.

Thanks for the PDF, nice when somebody provides more than the minimum information. Okay, from the same doc:

  The integer load and store quadword unaligned
  (LDQ_U, STQ_U) instructions ignore the low three
  bits of the byte address and always transfer an
  aligned quadword

So sort of right, if you squint and don't look too closely :-)

(edit: oh, you're the author? Didn't realise. Good stuff)
