Transfer information IR to binary
...ary.
This will give you an offset and you used it to update the addresses.
> [I'm always curious as to how these type of designs cope with someone modifying the checksumming code itself, but that's another problem - or is this one of these things where the checksum is stored in special hardwareprotected memory?].
For now, I store it into an special place.
My first solution for my problem was to used some temporary file but this is highly impractical.
Maybe I can create a temporary section into the binary but I didn’t find a lot of information about it.
Thanks,

Transfer information IR to binary
I will try to explain better what I do.
The main goal behind this is to verify that a part of code is not modified by someone else (it is an integrity check).
To do this, I create in IR a function who take 2 parameters, a begin and an end value.
This function perform an hash over the code area (from begin to end) and return it.
At first, I don’t know the addresses and the hash value so I put
