* HOL-Word: New extensive library and type for generic, fixed size machine words, with arithemtic, bit-wise, shifting and rotating operations, reflection into int, nat, and bool lists, automation for linear arithmetic (by automatic reflection into nat or int), including lemmas on overflow and monotonicity. Instantiated to all appropriate arithmetic type classes, supporting automatic simplification of numerals on all operations. Jointly developed by NICTA, Galois, and PSU. * still to do: README.html/document + moving some of the generic lemmas to appropriate place in distribution
