blanchet [Wed, 15 Dec 2010 11:26:28 +0100] rev 41134
added "type_sys" option to Sledgehammer
boehmes [Wed, 15 Dec 2010 11:07:13 +0100] rev 41133
merged
boehmes [Wed, 15 Dec 2010 10:52:43 +0100] rev 41132
updated SMT certificates
boehmes [Wed, 15 Dec 2010 10:12:48 +0100] rev 41131
fixed proof reconstruction for lambda-lifted problems (which broke when the lambda-lifting code was changed to operate on terms instead of on theorems)
boehmes [Wed, 15 Dec 2010 10:12:48 +0100] rev 41130
adapted the Z3 proof parser to recent changes in Z3's proof format;
keep the proof steps in an ordered list instead of in an Inttab (simplifies proof reconstruction code)
boehmes [Wed, 15 Dec 2010 10:12:48 +0100] rev 41129
also show function definitions for higher-order free variables in Z3 models
boehmes [Wed, 15 Dec 2010 10:12:48 +0100] rev 41128
always add pair rules and function update rules automatically (Boogie provides pairs and function update as built-in concepts and does not generate background axioms for them)
boehmes [Wed, 15 Dec 2010 10:12:44 +0100] rev 41127
re-implemented eta-expansion, lambda-lifting, and explicit application on terms (exploiting the control over the term structure);
abolished SMT interface concept in favor of solver classes (now also the translation configuration is stored in the context);
proof reconstruction is now expected to return a theorem stating False (and hence needs to discharge all hypothetical definitions);
built-in functions carry additionally their arity and their most general type;
slightly generalized the definition of fun_app
