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

merged

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;

replaced command 'nonterminals' by slightly modernized version 'nonterminal';

renamed structure MetaSimplifier to raw_Simplifer, to emphasize its meaning;

tuned signature;

clarified exports of structure Simplifier;

refer to regular structure Simplifier;

tuned;

updated SMT certificates

more precise/correct SMT error handling

fixed off-by-one and return proper error code -- never underestimate the number of oddities in Perl

discriminate SMT errors a bit better

keep track of errors in Z3 input file for debugging purposes

better propagation of stdout in case of failure + comply with strict/warnings

merge

cleaner handling of temporary files

merged

made sml/nj happy

added self-correcting wrapper for Z3 -- see comment in the file for details

impose a limit on the breadth of monomorphization (in addition to on the depth) to prevent an explosion of the number of monomorphic instances

no need to do a super-duper atomization if Metis fails afterwards anyway

removed unused variable

robustly handle SMT exceptions in Sledgehammer

make "debug" imply "blocking", since in blocking mode the exceptions flow through and are more instructive

reintroduce the higher penalty for skolems
