Oops. I'll go back and dig that out of the archive.

The inference rules look good. Some others you can do:
  V7 implies V6K  (this turns on V6K for M3 but that's safe because V6K
        only affects code which isn't reachable for M profile cores)
  V6K implies V6
  V7 implies THUMB2
  VFP4 implies VFP3
  VFP3 implies VFP
  M implies THUMB_DIV
  V6 implies AUXCR
