You forgot to mention which target you are talking about. ;)
Translation happens ahead of time. You do have access to CPUState but
its fields likely do not have the value you are interested in.
You'll have to read up on TCG and how to emit code that does what you
want to do with the register value at runtime rather than at translation
time.
