Summary
- repaired proofs
- moved some theorems into HOL main corpus
- official fact collection sign_simps
- dropped unused session references
- clear separation of types for bits (False / True) and Z2 (0 / 1)
- dropped weaker legacy alias; modernized syntax
- dropped former legacy input abbreviations
Changes from Mercurial (hg http://isabelle.in.tum.de/repos/isabelle/ default)
Summary
- moved some theorems into HOL main corpus
- misc tuning and modernization
- more theorems for proof of concept for word type
- official fact collection sign_simps
- tuned proofs
- avoid pseudo-collection to be used in generated proofs
- moved comment to approproiate place
- removed outcommented example which seems not to work as advertized
- clear separation of types for bits (False / True) and Z2 (0 / 1)
- generalized type classes for parity to cover word types also, which contain zero divisors
- slightly more specialized name for type class
- dropped weaker legacy alias
- slightly more stringent ordering of theorems
- removed relics of ASCII syntax for indexed big operators
- dropped former legacy input abbreviations
- using (*)-syntax for partially applied infix is fine, contrary to ancient op-syntax
- prefer fixed simpset for proof procedure
- tuned file system structure
- avoid spammed sledgehammer proofs
