isabelle: Graph

layered SMT setup, adapted SMT clients, added further tests, made Z3 proof abstraction configurable
2010-05-12, by boehmes
integrated SMT into the HOL image
2010-05-12, by boehmes
replaced More_conv.top_conv (which does not re-apply the given conversion to its results, only to the result's subterms) by Simplifier.full_rewrite
2010-05-12, by boehmes
use proper context operations (for fresh names of type and term variables, and for hypothetical definitions), monomorphize theorems (instead of terms, necessary for hypothetical definitions made during lambda lifting)
2010-05-12, by boehmes
split monolithic Z3 proof reconstruction structure into separate structures, use one set of schematic theorems for all uncertain proof rules (to extend proof reconstruction by missing cases), added several schematic theorems, improved abstraction of goals (abstract all uninterpreted sub-terms, only leave builtin symbols)
2010-05-12, by boehmes
added tracing of reconstruction data
2010-05-12, by boehmes
added new SMT translation files which use a simpler intermediate term representation and a simpler translation of builtin symbols, have less overhead for renaming symbols and generating the signature, add come with a simpler separation of formulas and terms

deleted SMT translation files (to be replaced by a simplified version)
