minimize imports; move domain class instances for powerdomain types into Powerdomains.thy

powerdomain theories require class 'bifinite' instead of 'domain'

type 'defl' takes a type parameter again (cf. b525988432e9)

reintroduce 'bifinite' class, now with existentially-quantified approx function (cf. b525988432e9)

renamed Bifinite.thy to Representable.thy

renamed CompactBasis.thy to Compact_Basis.thy

merged

updated SMT certificates

removed odd decoration of built-in symbols as Vars (instead provide built-in desctructor functions along with their inverse functions); removed odd retyping during folify (instead, keep all terms well-typed)

only linear occurrences of multiplication are treated as built-in (SMT solvers only support linear arithmetic in general); hide internal constants z3div and z3mod; rewrite div/mod to z3div/z3mod instead of adding extra rules characterizing div/mod in terms of z3div/z3mod

escape backticks in altstrings

added a timestamp to Nitpick in verbose mode for debugging purposes; turn on verbose mode for the examples

reduce the minimizer slack and add verbose information

two layers of timeouts seem to be less reliable than a single layer

move relevance filter into hard timeout

handle timeouts in Mirabelle more gracefully

made the relevance filter treat unatomizable facts like "atomize_all" properly (these result in problems that get E spinning seemingly forever); disabled inductions (E and SPASS don't like them), but kept "ext" (seems more harmless)

Add mixins to locale dependencies.

Enable show_hyps, which appears to be set in batch mode but in an interactive session.

Add mixins to sublocale command.

tuning

higher hard timeout

lower threshold where the binary algorithm kick in and use the same value for automatic minimization

compile

let each prover minimizes its own stuff (rather than taking the first prover of the list to minimize every prover's stuff)

use minimizing prover in Mirabelle

renamed function to run prover with minimizer and changed signature to clarify its semantics and make it a drop in replacement for "get_prover"

factored out running a prover with (optionally) an implicit minimizer phrase

merged;

remove option that doesn't work in Mirabelle anyway (Mirabelle uses Sledgehammer_Provers, not Sledgehammer_Run)

more precise error messages in "verbose" (or "debug") mode, following this morning's permission debacle

convenient syntax for setting provers -- useful for debugging, not for general consumption and hence not documented

merged

put the SMT weights back where they belong, so that they're also used by Mirabelle

added debugging option to find out how good the relevance filter was at identifying relevant facts

extra checking of name bindings for classes, types, consts; tuned;

more explicit references to structure Raw_Simplifier;

merged

Command 'type_synonym' (with single argument) supersedes 'types' (legacy feature);

dropped slightly odd Conv.tap_thy

avoid slightly odd Conv.tap_thy

allocate intermediate directories in module hierarchy

export experimental options

merged

compile

run the SMT relevance filter only once, then run the normalization/monomorphization code once _per class_ of SMT solvers

make timeout part of the SMT filter's tail

merge

split "smt_filter" into head and tail

fewer facts to SInE-E

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

trap one more Z3 error

fixed the command-line syntax for setting Yices' random seed

merged

updated SMT certificates

fixed lambda-lifting: shift indices of bound variables correctly (after locking the required bound variables) and apply bound variables to the new function symbol in the right order; fixed introduction of explicit application: use explicit application for every additional argument (grouping of arguments caused confusion when translating into the intermediate format)

adding exhaustive tester instances for numeric types: code_numeral, nat, rat and real

updated generated file;
