Paul,
I don't understand what you mean. Why can't I get registers value at
translation time?


The same block may be executed many times with different
inputs. If you want register values you have to do it at execution
time,
e.g. in do_interrupt.

Do you mean that If the same block is executed many times with different
inputs it is translated just once?


Thanks for help
