Wed, 12 May 2010 23:54:02 +0200 boehmes integrated SMT into the HOL image
Wed, 12 May 2010 23:54:01 +0200 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
Wed, 12 May 2010 23:54:00 +0200 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)
Wed, 12 May 2010 23:53:59 +0200 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)
Wed, 12 May 2010 23:53:58 +0200 boehmes added tracing of reconstruction data
Wed, 12 May 2010 23:53:57 +0200 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
Wed, 12 May 2010 23:53:56 +0200 boehmes deleted SMT translation files (to be replaced by a simplified version)
Wed, 12 May 2010 23:53:55 +0200 boehmes move the addition of extra facts into a separate module
Wed, 12 May 2010 23:53:54 +0200 boehmes normalize numerals: also rewrite Numeral0 into 0
Wed, 12 May 2010 23:53:53 +0200 boehmes added missing rewrite rules for natural min and max
Wed, 12 May 2010 23:53:52 +0200 boehmes rewrite bool case expressions as if expression
Wed, 12 May 2010 23:53:51 +0200 boehmes simplified normalize_rule and moved it further down in the code
Wed, 12 May 2010 23:53:50 +0200 boehmes merged addition of rules into one function
Wed, 12 May 2010 23:53:49 +0200 boehmes added simplification for distinctness of small lists
Wed, 12 May 2010 23:53:48 +0200 boehmes moved the addition of DLO tactic into the Z3 theory (DLO is required only for Z3 proof reconstruction)
