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
-- PMM
