Yes, condition code is a complication.  The hope would be to
automate as much as possible and then go through by hand and
find the rest.

In most cases the condition code shouldn't be so hard, but
catching those other cases could be tricky.  Especially if
you have things like  B *+12 around which could branch
between a CC setting instruction and a CC test without a
label in between.   That should be rare, though.

It might be that the conversion program will be customized
to the style of the assembly code that needs translating.
