2020-04-01Initialize theory rewriters in theories (#4197)Andres Noetzli
Until now, the `Rewriter` was responsible for creating `TheoryRewriter` instances. This commit adds a method `mkTheoryRewriter()` that theories override to create an instance of their corresponding theory rewriter. The advantage is that the theories can pass additional information to their theory rewriter (e.g. a statistics object).

2016-01-28Adding listeners to Options.Tim King
- Options -- Added the new option attribute :notify. One can get a notify() call on the Listener after a the option's value is updated. This is the new preferred way to achieve dynamic dispatch for options. -- Removed SmtOptionsHandler and pushed its functionality into OptionsHandler and Listeners. -- Added functions to Options for registering listeners of the notify calls. -- Changed a number of options to use the new listener infrastructure. -- Fixed a number of warnings in options. -- Added the ArgumentExtender class to better capture how arguments are inserted while parsing options and ease memory management. Previously this was the "preemptGetopt" procedure. -- Moved options/options_handler_interface.{cpp,h} to options/options_handler.{cpp,h}. - Theories -- Reimplemented alternative theories to use a datastructure stored on TheoryEngine instead of on Options. - Ostream Handling: -- Added new functionality that generalized how ostreams are opened, options/open_stream.h. -- Simplified the memory management for different ostreams, smt/managed_ostreams.h. -- Had the SmtEnginePrivate manage the memory for the ostreams set by options. -- Simplified how the setting of ostreams are updated, smt/update_ostream.h. - Configuration and Tags: -- Configuration can now be used during predicates and handlers for options. -- Moved configuration.{cpp,h,i} and configuration_private.h from util/ into base/. -- Moved {Debug,Trace}_tags.* from being generated in options/ into base/. - cvc4_private.h -- Upgraded #warning's in cvc4_private.h and cvc4_private_library.h to #error's. -- Added public first-order (non-templatized) member functions for options get and set the value of options outside of libcvc4. Fixed all of the use locations. -- Made lib/lib/clock_gettime.h a cvc4_private_library.h header. - Antlr -- Fixed antlr and cvc4 macro definition conflicts that caused warnings. - SmtGlobals -- Refactored replayStream and replayLog out of SmtGlobals. -- Renamed SmtGlobals to LemmaChannels and moved the implementation into smt_util/lemma_channels.{h,cpp}.

2016-01-08Removing StatisticsRegistry's static functions current() and registerStat().Tim King
- The functionality the get the StatisticsRegistry attached to the SmtEngine was previously through StatisticsRegistry::current(). This is the dominant StatisticsRegistry in the code. (There is another StatisticsRegistry attached to the NodeManager.) Having this be a static function on StatisticsRegistry requires the use of an SmtEngine in the wrong compilation unit. - Usages of StatisticsRegistry::current() that were visible in prop/{bvminisat,minisat} has been removed. A pointer to the relevant StatisticsRegistry should be passed instead into the constructor. - The function StatisticsRegistry::current() has been replaced by SmtScope::currentStatisticsRegistry(). SmtScope is in the libcvc4 package, where SmtEngine is available in the compilation unit. - The function smtStatisticsRegistry() is a synonym for SmtScope::currentStatisticsRegistry() in smt/smt_statistics_registry.h. This header has fewer include dependencies than the one for SmtScope. - Correspondingly, the static functions StatisticsRegistry::{registerStat, unregisterStat} have been removed. One should instead use smtStatisticsRegistry()->{registerStat,unregisterStat} instead. - The KEEP_STATISTIC macro has been moved into smt/smt_statistics_registry.h. - Documents the reason StatisticsRegistry is CVC4_PUBLIC. This lets me remove the warning I added. - Removing most operators for timespec from statistics_registry.h file. These a bit error prone in clang. - Most of the really confusing ifdef's in util/statistics_registry.h are gone.
2016-01-05Add SmtGlobals ClassTim King
- The options replayStream, lemmaInputChannel, lemmaOutputChannel have been removed due to their datatypes. These datatypes were previously pointers to types that were not usable from the options/ library. - The option replayLog has been removed due to inconsistent memory management. - SmtGlobals is a class that wraps a pointer to each of these removed options. These can each be set independently. - There is a single SmtGlobals per SmtEngine with the lifetime of the SmtEngine. - A pointer to this is freely given to the user of an SmtEngine to parameterize the solver after construction. - Selected classes have been given a copy of this pointer in their constructors. - Removed the dependence on Node from Result. Moving Result back into util/.

2015-12-14Refactoring Options Handler & Library Cycle BreakingTim King
What to Know As a User: A number of files have moved. Users that include files in the public API in more refined ways than using #include <cvc4.h> should consult which files have moved. Note though that some files may move again after being cleaned up. A number of small tweaks have been made to the swig interfaces that may cause issues. Please file bug reports for any problems. The Problem: The build order of CVC4 used to be [roughly] specified as: options < expr < util < libcvc4 < parsers < main Each of these had their own directories and their own Makefile.am files. With the exception of the util/ directory, each of the subdirectories built exactly one convenience library. The util/ directory additionally built a statistics library. While the order above was partially correct, the build order was more complicated as options/Makefile.am executed building the sources for expr/Makefile.am as part of its BUILT_SOURCES phase. This options/Makefile.am also build the options/h and options.cpp files in other directories. There were cyclical library dependencies between the first four above libraries. All of these aspects combined to make options extremely brittle and hard to develop. Maintaining these between clang versus gcc, and bazel versus autotools has become increasing unpredictable. The Solution: To address these cyclic build problems, I am simplifying the build process. Here are the main things that have to happen: 1. util/ will be split into 3 separate directories: base, util, and smt_util. Each will have their own library and Makefile.am file. 2. Dependencies for options/ will be moved into options/. If a type appears as an option, this file will be moved into options. 3. All of the old options_handlers.h files have been refactored. 4. Some files have moved from util into expr/ to resolve cycles. Some of these moves are temporary. 5. I am removing the libstatistics library. The constraints that the CVC4 build system will eventually satisfy are: - The include order for both the .h and .cpp files for a directory must respect the order libraries are built. For example, a file in options/ cannot include from the expr/ directory. This includes built source files such as those coming from */kinds files and */options files. - The types definitions must also respect the build order. Forward type declarations will be allowed in exceptional, justified cases. - The Makefile.am for a directory cannot generate a file outside of the directory it controls. (Or call another Makefile.am except through subdirectory calls.) - One library per Makefile.am. - No extra copies of libraries will be built for the purpose of distinguishing between external and internal visibility in libraries for building parser/ or main/ libraries and binaries. Any function used by parser/ and main/ will be labeled with CVC4_PUBLIC and be in a public API. (AFAICT, libstatistics was being built exactly to skirt this.) The build order of CVC4 can now be [roughly] specified as base < options < util < expr < smt_util < libcvc4 < parsers < main The distinction between "base < options < util < expr" are currently clean. The relationship between expr and the subsequent directories/libraries are not yet clean. More details about the directories: base/ The new directory base/ contains the shared utilities that are absolutely crucial to starting cvc4. The list currently includes just: cvc4_assert.{h,cpp}, output.{h,cpp}, exception.{h,cpp}, and tls.{h, h.in, cpp}. These are things that are required everywhere. options/ The options/ directory is self contained. - It contains all of the enums that appear as options. This includes things like theory/bv/bitblast_mode.h . - There are exactly 4 classes that handled currently using forward declarations currently to this: LogicInfo, LemmaInputChannel, LemmaOutputChannel, and CommandSequence. These will all be removed from options. - Functionality of the options_handlers.h files has been moved into smt/smt_options_handler.h. The options library itself only uses an interface class defined in options/options_handler_interface.h. We are now using virtual dispatch to avoid using inlined functions as was previously done. - The */options_handlers.h files have been removed. - The generated smt/smt_options.cpp file has been be replaced by pushing the functionality that was generated into: options/options_handler_{get,set}_option_template.cpp . The non-generated functionality was moved into smt_engine.cpp. - All of the options files have been moved from their directories into options/. This means includes like theory/arith/options.h have changed to change to options/arith_options.h . util/ The util/ directory continues to contain core utility classes that may be used [almost] everywhere. The exception is that these are not used by options/ or base/. This includes things like rational and integer. These may not use anything in expr/ or libcvc4. A number of files have been moved out of this directory as they have cyclic dependencies graph with exprs and types. The build process up to this directory is currently clean. expr/ The expr/ directory continues to be the home of expressions. The major change is files moving from util/ moving into expr/. The reason for this is that these files form a cycle with files in expr/. - An example is datatype.h. This includes "expr/expr.h", "expr/type.h" while "expr/command.h" includes datatype.h. - Another example is predicate.h. This uses expr.h and is also declared in a kinds file and thus appears in kinds.h. - The rule of thumb is if expr/ pulls it in it needs to be independent of expr/, in which case it is in util/, or it is not, in which case it is pulled into expr/. - Some files do not have a strong justification currently. Result, ResourceManager and SExpr can be moved back into util/ once the iostream manipulation routines are refactored out of the Node and Expr classes. - Note the kinds files are expected to remain in the theory/ directories. These are only read in order to build sources. - This directory is not yet clean. It contains forward references into libcvc4 such as the printer. It also makes some classes used by main/ and parser CVC4_PUBLIC. smt_util/ The smt_util/ directory contains those utility classes which require exprs, but expr/ does not require them. These are mostly utilities for working with expressions and nodes. Examples include ite_removal.h, LemmaInputChannel and LemmaOutputChannel. What is up next: - A number of new #warning "TODO: ..." items have been scattered throughout the code as reminders to myself. Help with these issues is welcomed. - The expr/ directory needs to be cleaned up in a similar to options/. Before this happens statistics needs to be cleaned up.
