There are two data structures that remain the same... the first structure describe bit-fields within a 64-bit register. The 2nd structure describes some meta-attributes about the register.

min to max will be 0 to 2^64 - 1.

So given these data structures are not varying, it is sounding like pack templates might be the way to go. Perhaps there will be a challenge in that the 1st data structure is an array with varying numbers of elements, although the structure will always be the same.

Thanks for pointing out Storable and BZip2. That is more food for thought along the way.

Thanks, Matt.
