Eliminates NodeHashFunction, TNodeHashFunction and TypeNodeHashFunction.

|
This removes the special case of TUPLE_UPDATE and RECORD_UPDATE in favor of the more general datatype update.
Datatype update is handled analogously to APPLY_SELECTOR / APPLY_TESTER.

Previously the SMT2 printer would print pattern lists wrong when they were not printed as part of a binder containing it. This commit fixes this by removing an unused hardcoded restriction that led to issues when printing the ASTs of proof nodes containing patterns.

This PR does a first round of refactoring and gets rid of a significant portion of generated code. In particular
- it removes options::optionName.wasSetByUser() (we still have Options::wasSetByUser())
- it removes options::optionName.set() (we still have Options::set())
- it removes options::optionName.getName() in favor of options::optionName.name
- it removes the specializations of Options::assign() and Options::assignBool() from the headers
- it eliminates runHandlerAndPredicates() and runBoolPredicates()
The removed methods are only used in few places with are changed to using Options::current().X() instead.
In the future, we also want to get rid of options::optionName() and use Options::operator[]() instead, and furthermore not use Options::current() but use the options from the Env object. This PR already adds Env::getOption() as a shorthand for Env::getOptions()[...] and uses it as a proof of concept within SmtEngine.

This adds the command declare-pool to the public API. It also adds parsing support for this feature, lifts the internal kinds to public kinds, adds an example regression, and a unit test for the new declare-pool solver method.

This renames everything but GitHub links and build system related
macros. Switching the build system to cvc5 will be the last step in the
renaming process.

Currently, SEXPR applications are given a parametric type SEXPR_TYPE applied to the types of its arguments. This means that SEXPR that are type checked consume roughly double the memory. This issue arises in practice when printing proofs in the internal calculus.
There is no need to have SEXPR_TYPE as a parametric type, this PR makes SEXPR simply typed.
Also moves some implementation of TypeNode methods to type_node.cpp.

This pushes all symfpu specific parts from FloatingPoint into
FloatingPointLiteral. FloatingPoint is now generic. An additional
FloatingPointLiteral implementation using MPFR will be made configurable
similiarly to how we handle Integers with either GMP or CLN backend.

This PR eliminates all remaining uses of SExpr outside of statistics.
|
|
This fixes a subtle bug with how quantifier bodies are letified.
It makes our letification more conservative so that let symbols are never pushed inside quantifier bodies, instead quantifier bodies are letified independently of the context.

This PR does some more cleanup of the includes.
|
|
|
|
This commit removes the partial UDIV/UREM operator handling. BITVECTOR_UDIV and BITVECTOR_UREM are now total.
|
|
This commit removes parser and printer support for old SMT-LIB standards and also converts all regression tests to 2.6.
|
|
Similar to #6031, this PR implements suggestions from iwyu to reduce the number of includes in header files by introducing forward declarations and moving includes to source files.
|
|
This PR is a step towards removing SExpr class. It replaces SExpr with std::string for set-info and set-option commands.
|
|
This PR adds tuple projection operator to the theory of data types.
It Also adds helper functions for selecting elements from a tuple.
|
|
This PR cleans up a ton of includes, based on the suggestions of iwyu.
Mostly, it removes includes from header files in favor of forward declarations and adds includes to source files.

This permits access to the static method string smtKindString(Kind k, Variant v) which is required for LFSC proof conversion. It also makes a fix to how a string kind is printed.

This PR introduces a new arithmetic kind for indexed root predicates.
An indexed root predicate compares a real variable to the k'th root of a given polynomial as follows:
Let IRP_k(x ~ 0, p) an indexed root predicate with k a non-negative number, x some real variable, ~ an arithmetic relation (e.g. =, <, ...), and p a polynomial over x (and possibly other variables).
If p contains variables apart from x, we can only evaluate the expression over a suitable assignment for at least these variables.
The evaluation of this expression is equivalent to computing the k'th real root of p in x (with all other variables evaluated over a given assignment) and comparing this real root to zero (according to the relation symbol ~).
Note that we currently do not intend to use this structure for solving, but require it for representing and printing CAD proofs.

Towards eliminating dependencies on quantifiers engine.
This replaces the custom implementation of lemma management in quantifiers engine with the standard one.
It makes a few minor changes to the standard inference manager classes to ensure the same behavior for quantifiers.
Note that some minor changes in behavior are introduced in this PR, such as being more consistent about caching/rewriting lemmas. This should not have any major impact.
|
|
This is in preparation for refactoring the printing of instantiations. We will migrate the printing of instantiations (currently done in the Instantiate module within quantifiers engine) to somewhere more high level e.g. the SmtEngine or in the command layer. This will make the infrastructure for dumping instantiations much more flexible, as implemented on proof-new.

This deletes variable flags from NodeManager::mkVar and moves ExprManager sort flags to NodeManager.
These flags are used for determining when a variable or sort should be printed via the old dump infrastructure. The old dump infrastructure is simplified in this PR accordingly.
This PR should preserve behavior of the previous dumping with a minor exception that the internal trace "declarations" will also included symbols introduced from define-fun. This will be further refactored later. This is in preparation for removing the includes expr.h/expr_manager.h from node_manager.h.

This PR adds inference generator for basic bag rules.
|
|
Leftover from a development branch.
|
|
Simplifies synth-fun printing to assume that the function-to-synthesize should be printed with the proper name and return type.
|
|
Also fixes a bug where patterns would be printed with the wrong scope (that included the bound variable list).
|
|
This PR fixes #5448. SynthFunCommand::toStream used to call d_grammar->resolve even when d_grammar is a nullptr. This PR fixes the issue and modifies the signature of Printer::toStreamCmdSynthFun to make it clear that grammar is an optional argument.
|
|
This PR relates to #4987 .
Our plan is to:
delete the model keyword (done in #5415 )
avoid printing extra declarations by default (done in #5432 )
wrap UF values with as expressions.
This PR does step 3, fixes a regression accordingly, and adds the formula from #4987 and a variant of it to the regressions.
|
|
|
|
This has fully been replaced by the new let binding.
|
|
Also changes names slightly to avoid accidental uses of toStream, which can lead to infinite loops if the wrong version is used.

Required for removing the old DagificationVisitor
|
|
This makes symbol manager be in charge of determining which sorts and terms to print in response to get-model. This eliminates the need for the parser to call ExprManager::mkVar (and similar methods) with custom flags.
This requires significant simplifications to the printers for models, where instead of a NodeCommand, we take a Sort or Term to print in the model.
This is one of the last remaining steps for migrating the parser to the new API.
The next step will be to remove a lot of the internal infrastructure for managing expression names, commands to print in models, node commands, node listeners, etc.
|
|
|
|
|
|
Also fixes some whitespace issues in printing quantified formulas.
|
|
This PR uses the symbol manager for handling names for unsat cores.
This replaces interfaces in SmtEngine for managing expression names. It removes the SetExpressionName command.
|
|
This utility will replace the dagification visitor for printing lets for Node in the smt2 printer, and will be used further in e.g. LFSC proof printing.
