50 This check is necessary because std::bitset only provides conversion to
51 unsigned long or unsigned long long via to_ulong() or to_ullong(). there are
52 a few places in the code where to_ullong() is used, however if VSZ is larger
53 than a value the host can support then bitset will throw a runtime exception.
54
55 we should remove all use of to_long() or to_ullong() so we can have VSZ
56 greater than 64b, however until that is done this assert is required.
