took out broken support for Yices from SMT2 stack -- see 'NEWS' for rationale

made CVC3 work with SMT2 stack

properties of Erlang and exponentially distributed random variables (by Sudeep Kanav)

clean up ContNotDenum; add lemmas by Jeremy Avigad and Luke Serafin

uniform treatment of trivial unit instances: simplify by default, unfold in code preprocessor

adapted examples to changes in SMT triggers

reduces Sledgehammer dependencies

eliminate dependency of SMT2 module on 'list'

tuning

removed subsumed record-related code, now that records are registered as 'ctr_sugar'

made lookup more robust in the face of missing (dummy) case constant

use 'ctr_sugar' abstraction in SMT(2)

register record extensions as freely generated types

mixin definitions are within scope of "for"s of import expression

proper proof context transfer wrt. background theory avoids ad-hoc restore operation

refactoring

moved generic code further up

tuned code

factor out SMT-LIB 2 type/term parsing from Z3-specific code

simplify slightly ATP proof generated for Z3

tuned whitespaces

updated contributors to include students

moved new highly experimental Waldmeister-specific code (authored by Albert Steckermeier) into Isabelle

adapted SMT examples to new, corrected handling of 'typedef'

fixed unsoundness in SMT(2) as oracle: don't register typedef Abs_x as constructor unless it is known to be injective

updated NEWS slightly

updated docs w.r.t. Z3

rationalized CVC3 and Yices environment variable -- no need (unlike for Z3) to distinguish between old and new versions

removed '_new' sufffix in SMT2 solver names (in some cases)

removed old SMT module from Sledgehammer

got rid of 'listF' example, which is now subsumed by the real 'list' type

changed syntax of map: and rel: arguments to BNF-based datatypes

tuning

updated Z3 certificates

generate ':named' attributes in SMT-LIB 2 problems, to facilitate reconstruction

tuning

add type class instances for unit

use 'where' clause for selector default value syntax

tuning

added List.union

Sup/Inf on functions decoupled from complete_lattice.

tuned data structure

recovered level-free fishing for locale, accidentally lost in dce365931721

tuned terminology: emphasize stack-like nature of nested local theories

self-contained locale_declaration operation

yet another attempt for terminology: foo_target_bar denotes an operation bar operating solely on the target context of target foo, foo_bar denotes a whole stack of operations to accomplish bar for target foo

tuned

recovered structure of module, which got somehow convoluted due to incremental modifications

re-unified approach towards class and locale consts, with refined terminology: foo_const_declaration denotes declaration for a particular logical layer, foo_const the full stack for a particular target

revert effect of 63c7b29d29ac -- existing pervasive interpretation of class order for dvd etc. is too obstrusive at the moment

less ad-hoc verision of educated guess: guess identity of declaration morphism wrt. canonical morphism rather than observing particular effects of declaration morphisms only; n.b. this fullfills promise given in 63c7b29d29ac

treat non-canonical interpretations of classes the same way as ordinary locale interpretations

tuned

avoid odd Named_Target.reinit altogether

clarified terminology: toplevel is interwined with named targets in particular, not with local theories in general

less baroque interface

dropped obscure and unused ad-hoc before_exit hook for named targets

added lemma

mira: USER_HOME must exist for building JEdit documentation
