mechanism to keep SMT input and output files around in Mirabelle
2010-12-21, by blanchet
proper handling of the arguments of SMT builtins -- for numerals, ignore the arguments (Pls, Bit0, Bit1, ..), for functions, consider them;
2010-12-21, by blanchet
added "smt_triggers" option to experiment with triggers in Sledgehammer;
2010-12-21, by blanchet
enable E weight generation with unofficial latest version of E (tentatively called E 1.2B) -- backed by Judgment Day
2010-12-21, by blanchet
Cygwin: Poly/ML 5.4.0 requires libgmp3;
2010-12-20, by wenzelm
updated to polyml-5.4.0;
2010-12-20, by wenzelm

merged
2010-12-20, by boehmes
avoid ML structure aliases (especially single-letter abbreviations)
2010-12-20, by boehmes
added an additional beta reduction: unfolding of special quantifiers might leave terms unnormalized wrt to beta reductions
2010-12-20, by boehmes
merged
2010-12-20, by huffman
configure domain package to work with HOL option type

2010-12-20, by huffman
simplify proofs
2010-12-20, by huffman
beta-reduction simproc uses lemma Abs_cfun_inverse2 instead of beta_cfun, to be more robust against eta-contraction
2010-12-20, by huffman
configure domain package to work with HOL sum type
2010-12-20, by huffman
replace list_map function with an abbreviation
2010-12-20, by huffman
merged
2010-12-20, by blanchet
run SPASS and Vampire in SOS mode only if >= 50 facts are passed -- otherwise we are probably minimizing and then it's better if the prover is run only once with a full strategy
2010-12-20, by blanchet
disable feature that was enabled by mistake
2010-12-20, by blanchet
make exceptions more transparent in "debug" mode

type_lifting for predicates
2010-12-20, by haftmann
proper identifiers for consts and types;
2010-12-20, by wenzelm
some attempts to fit diagnostic output into regular TTY (75-80 characters per line);
2010-12-20, by wenzelm
tuned/clarified some component settings;
2010-12-20, by wenzelm
slightly more standard Isabelle_System.with_tmp_file/with_tmp_dir (cf. Scala version);
2010-12-20, by wenzelm
purged some comments (Locale_Test is already clean thanks to configuration options);
2010-12-20, by wenzelm
actually enable show_hyps option, unlike local_setup in 6da953d30f48 which merely affects the (temporary) auxiliary context;
2010-12-20, by wenzelm
merged
2010-12-20, by boehmes
updated SMT certificates
2010-12-20, by boehmes
re-introduced support for nonlinear multiplication in Z3 (overriding the built-in linear multiplication of the SMT-LIB class of solvers)
2010-12-20, by boehmes
derived SMT solver classes override inherited properties (properties of derived classes have a higher priority than properties of base classes)
2010-12-20, by boehmes
perform monomorphization during normalization: schematic numerals might be monomorphized into built-in numerals and then numeral normalization is required
2010-12-20, by boehmes

more convenient order of type variables

2010-12-19, by huffman
minimize imports; move domain class instances for powerdomain types into Powerdomains.thy
2010-12-19, by huffman
powerdomain theories require class 'bifinite' instead of 'domain'
2010-12-19, by huffman
type 'defl' takes a type parameter again (cf. b525988432e9)
2010-12-19, by huffman

2010-12-19, by boehmes
removed odd decoration of built-in symbols as Vars (instead provide built-in desctructor functions along with their inverse functions);
2010-12-19, by boehmes
only linear occurrences of multiplication are treated as built-in (SMT solvers only support linear arithmetic in general);
2010-12-19, by boehmes
escape backticks in altstrings

2010-12-18, by blanchet
handle timeouts in Mirabelle more gracefully
2010-12-18, by blanchet
made the relevance filter treat unatomizable facts like "atomize_all" properly (these result in problems that get E spinning seemingly forever);
2010-12-18, by blanchet
Add mixins to locale dependencies.
2010-12-18, by ballarin
Enable show_hyps, which appears to be set in batch mode but in an interactive session.

2010-12-18, by blanchet
merged;
2010-12-17, by wenzelm
remove option that doesn't work in Mirabelle anyway (Mirabelle uses Sledgehammer_Provers, not Sledgehammer_Run)
2010-12-17, by blanchet
more precise error messages in "verbose" (or "debug") mode, following this morning's permission debacle
2010-12-17, by blanchet
convenient syntax for setting provers -- useful for debugging, not for general consumption and hence not documented
2010-12-17, by blanchet
merged
2010-12-17, by blanchet
put the SMT weights back where they belong, so that they're also used by Mirabelle

fewer facts to SInE-E
2010-12-17, by blanchet
Z3 sometimes reports two errors, with the first one referring to line 1 for some strange reason -- but it makes no sense to kill line 1, so we traverse the errors in reverse and consider only the last error
2010-12-17, by blanchet
trap one more Z3 error
2010-12-17, by blanchet
