2004-05-03 schirmer 2004-05-03 reimplementation of HOL records; only one type is created for each record extension, instead of one type for each field. See NEWS.
2003-05-14 schirmer 2003-05-14 Adapted to changes in Map.thy
2002-11-01 schirmer 2002-11-01 Inserted some extra paragraphs in large proofs to make tex run...
2002-10-31 schirmer 2002-10-31 "Definite Assignment Analysis" included, with proof of correctness. Large adjustments of type safety proof and soundness proof of the axiomatic semantics were necessary. Completeness proof of the loop rule of the axiomatic semantic was altered. So the additional polymorphic variants of some rules could be removed.
2002-09-30 berghofe 2002-09-30 Adapted to new simplifier.
2002-07-16 schirmer 2002-07-16 Added conditional and (&&) and or (||).
2002-07-10 schirmer 2002-07-10 Added unary and binary operations like (+,-,<, ...); Added smallstep semantics (no proofs about it yet).
2002-02-25 wenzelm 2002-02-25 clarified syntax of ``long'' statements: fixes/assumes/shows;
2002-02-22 schirmer 2002-02-22 Added check for field/method access to operational semantics and proved the acesses valid.
