2013-12-14 wenzelm 2013-12-14 proper context for basic Simplifier operations: rewrite_rule, rewrite_goals_rule, rewrite_goals_tac etc.; clarified tool context in some boundary cases;
2013-04-18 wenzelm 2013-04-18 simplifier uses proper Proof.context instead of historic type simpset;

2012-01-14 wenzelm 2012-01-14 tuned white space;

2010-09-07 nipkow 2010-09-07 expand_fun_eq -> ext_iff expand_set_eq -> set_ext_iff Naming in line now with multisets

More precisely, the simproc pulls an equation x=t (or t=x) out of a nest of conjunctions to the front where the simp rule singleton_conj_conv(2) converts to "if".

2003-05-14 schirmer 2003-05-14 Adapted to changes in Map.thy
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.
2002-08-27 wenzelm 2002-08-27 *** empty log message ***
2002-02-22 schirmer 2002-02-22 Added check for field/method access to operational semantics and proved the acesses valid.
