2021-03-02Clean up includes to reduce compile times (#6031)Gereon Kremer
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.
2020-11-19Include stddef.h (needed for size_t) in cvc4_public.h (#5476)Aina Niemetz
This further removes obsolete explicit includes of stdint.h.
2020-11-05Simplify printing with respect to expression types (#5394)Andrew Reynolds
This removes infrastructure for stream property related to printing type annotations on all variables. This is towards refactoring the printers.

2019-10-22NodeValue: Eliminate redundant NBITS macros. (#3400)Aina Niemetz
Previously, the metakind header defined macros for the number of bits reserved for fields in the NodeValue "header" (for the reference count, the node kind, the number of children and the node id). These macros were redundant, since the only one using them was the NodeValue itself, which redefined them (while using them) as constants in the class. Additionally, MAX_CHILDREN was defined (using these macros) not only in the metakind header, but redefined in other places. This commit defines the above values as constexpr members of the NodeValue class and cleans up redundancy.

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.

2012-06-09Dagification of output expressions.Morgan Deters
By default, common subexpressions are dagified if they appear > 1 time and are not constants or variables. This can be changed with --default-expr-dag=N --- N is a threshold such that if the subexpression occurs > N times, it is dagified; a setting of 0 turns off dagification entirely. If you notice strange dumping behavior (taking too long to print anything, e.g.), revert to the old behavior with --default-expr-dag=0 and let me know of the problem.

2010-10-12Merge from cc-memout branch. Here are the main pointsMorgan Deters
* Add ContextMemoryAllocator<T> allocator type, conforming to STL allocator requirements. * Extend the CDList<> template to take an allocator (defaults to std::allocator<T>). * Add a specialized version of the CDList<> template (in src/context/cdlist_context_memory.h) that allocates a list in segments, in context memory. * Add "forward" headers -- cdlist_forward.h, cdmap_forward.h, and cdset_forward.h. Use these in public headers, and other places where you don't need the full header (just the forward-declaration). These types justify their own header (instead of just forward-declaring yourself), because they are complex templated types, with default template parameters, specializations, etc. * theory_engine.h no longer depends on individual theory headers. (Instead it forward-declares Theory implementations.) This is especially important now that theory .cpp files depend on TheoryEngine (to implement Theory::getValue()). Previously, any modification to any theory header file required *all* theories, and the engine, to be completely rebuilt. * Support memory cleanup for nontrivial CONSTANT kinds. This resolves an issue with arithmetic where memory leaked for each distinct Rational or Integer that was wrapped in a Node.
2010-10-08* (define-fun...) now has proper type checking in non-debug buildsMorgan Deters
(resolves bug #212) * also closed some other type checking loopholes in SmtEngine * small fixes to define-sort (resolves bug #214) * infrastructural support for printing expressions in languages other than the internal representation language using an IO manipulator, e.g.: cout << Expr::setlanguage(language::output::LANG_SMTLIB_V2) << expr; main() sets the output language for all streams to correspond to the input language * support delaying type checking in debug builds, so that one can debug the type checker itself (before it was difficult, because debug builds did all the type checking on Node creation!): new command-line flag --no-early-type-checking (only makes sense for debug builds) * disallowed copy-construction of ExprManager and NodeManager, and made other constructors explicit; previously it was easy to unintentionally create duplicate managers, with really weird results (i.e., disappearing attributes!)

2010-06-04** Don't fear the files-changed list, almost all changes are in the **Morgan Deters
** file-level documentation at the top of the sources. ** This is the "make bugzilla stop bugging me" bugfix commit. * Remove BackedNodeBuilder<> and collapse NodeBuilder<> hierarchy. Updated documentation in the file. Resolves bug #99. * Convenience NodeBuilders (PlusNodeBuilder, OrNodeBuilder, etc.) moved into a separate file. Partially resolves bug #100. * Moved isAssociative(Kind) into kind.h (and into the CVC4::kind namespace) instead of metakind.h (where it was in CVC4::metakind). This clears up a warning (private #inclusion) from the SMT and SMT2 parsers, and maybe makes more sense anyways, since this is based on the kind (and not the metakind) of an operator. * Documentation improvement; doxygen top-level \file gestures, \brief gestures for files, etc. Changed contrib/update-copyright.pl for this change, and post-processed to add \brief. Resolves bug #98. * Removed ExprManager::mkExpr(Kind) and NodeManager::mkNode(Kind). They no longer made sense. Resolves bug #91.
