2019-03-12time: add double type for span multiplicationsFrank Busse
2018-10-30Base time API upon std::chronoFrank Busse
This should not change the behaviour of KLEE and mimics the old API. - functions moved from util into time namespace - uses time points and time spans instead of double - CLI arguments now have the form "3h5min8us" Changed command line parameters: - batch-time (double to string) - istats-write-interval (double to string) - max-instruction-time (double to string) - max-solver-time (double to string) - max-time (double to string) - min-query-time-to-log (double to string) - seed-time (double to string) - stats-write-interval (double to string) - uncovered-update-interval (double to string) - added: log-timed-out-queries (replaces negative max-solver-time)

2016-11-19[CMake] Remove unneeded dependency declarations for the unit tests.Dan Liew
These were changes that I forgot to make in dda296e09ee53ed85ccf1c3f08e7e809adce612e .
2016-11-07Implement a CMake based build system for KLEE.Dan Liew
This is based off intial work by @jirislaby in #481. However it has been substantially modified. Notably it includes a separate build sytem to build the runtimes which is inspired by the old build system. The reason for doing this is because CMake is not well suited for building the runtime: * CMake is configured to use the host compiler, not the bitcode compiler. These are not the same thing. * Building the runtime using `add_custom_command()` is flawed because we can't automatically get transitive depencies (i.e. header file dependencies) unless the CMake generator is makefiles. (See `IMPLICIT_DEPENDS` of `add_custom_command()` in CMake). So for now we have a very simple build system for building the runtimes. In the future we can replace this with something more sophisticated if we need it. Support for all features of the old build system are implemented apart from recording the git revision and showing it in the output of `klee --help`. Another notable change is the CMake build system works much better with LLVM installs which don't ship with testing tools. The build system will download the sources for `FileCheck` and `not` tools if the corresponding binaries aren't available and will build them. However `lit` (availabe via `pip install lit`) and GTest must already be installed. Apart from better support for testing a significant advantage of the new CMake build system compared to the existing "Autoconf/Makefile" build system is that it is **not** coupled to LLVM's build system (unlike the existing build system). This means that LLVM's autoconf/Makefiles don't need to be installed somewhere on the system. Currently all tests pass. Support has been implemented in TravisCI and the Dockerfile for building with CMake. The existing "Autoconf/Makefile" build system has been left intact and so both build systems can coexist for a short while. We should remove the old build system as soon as possible though because it creates an unnecessary maintance burden.
2016-09-29Fix bug in `AssignmentEvaluator` where NotOptimizedExpr would not (#466)Dan Liew
* Add unittest to check that the `Assignment` class can evaluate expressions containing a `NotOptimizedExpr`. * Fix the `AssignmentTest.FoldNotOptimized` unit test by teaching the `ExprEvaluator` to fold `NotOptimizedExpr` nodes.

2016-02-10Add some of the basic plumbing required to support a Z3 solver in KLEE.Dan Liew
2016-01-14Refactor the MetaSMT makefile commands into its own file which canDan Liew
be included by tools that needs to link against MetaSMT. Apart from making the Makefile code cleaner this allowed the Solver unit test linking to succeed when not building with STP support. Unfortunately when using MetaSMT as the core solver the Solver unit tests do not pass. Clearly no one tried this before... :(
2016-01-14Make it possible to build KLEE without using STP and only MetaSMT.Dan Liew
The default core solver is STP if KLEE is built with STP otherwise it is MetaSMT. Whilst I'm here rename SUPPORT_METASMT macro to ENABLE_METASMT for consistency.
2016-01-12Refactor setting the core solver (i.e. STP, MetaSMT or DummySolver) by providingDan Liew
a ``createCoreSolver()`` function. The solver used is set by the new ``--solver-backend`` command line argument. The default is STP. This change necessitated refactoring the MetaSMT stuff. That clearly didn't belong in the Executor! The MetaSMT command line option is now ``--metasmt-backend`` as this only picks the MetaSMT backend. In order to use MetaSMT ``--solver-backend=metasmt`` needs to be passed. Note I don't have MetaSMT built on my development machine so I don't know if the MetaSMT stuff even compiles...
2015-12-18Fix memory leaks of ``Array`` objects detected by ASan.Dan Liew
Some of these leaks were introduced by the factory constructor for Array objects (f049ff3bc04daead8c3bb9f06e89e71e2054c82a) but a few others have been around for far longer. This leak was fixed by introducing a ``ArrayCache`` object which has two purposes * Retains ownership of all created ``Array`` objects and destroys them when the ``ArrayCache`` destructor is called. * Mimic the caching behaviour for symbolic arrays that was introduced by f049ff3bc04daead8c3bb9f06e89e71e2054c82a where arrays with the same name and size get "uniqued". The Executor now maintains a ``arrayCache`` member that it uses and passes by pointer to objects that need to construct ``Array`` objects (i.e. ``ObjectState``). This way when the Executor is destroyed all the ``Array`` objects get freed which seems like the right time to do this. For Kleaver the ``ParserImpl`` has a ``TheArrayCache`` member that is used for building ``Array`` objects. This means that the Parser must live as long as the built expressions will be used otherwise we will have a use after free. I'm not sure this is the right design choice. It might be better to transfer ownership of the ``Array`` objects to the root ``Decl`` returned by the parser.
2015-04-03Upstream STP now depends on an external build of minisat. Attempt toDan Liew
fix travis build of upstream STP and also how KLEE links against STP.
2015-02-22Added factory method for Arrays + hid constructors from outside callsEric Rizzi
The way that Arrays were handled in the past led to the possibility of aliasing issues. This occured whenever a new branch discovered an array for the first time. Each branch would create a new instance of the same array without seeing if it had been created before. Therefore, should a new branch encounter the same state as some previous branch, the previous branch's solution wouldn't satisfy the new state since they didn't recognize they were referencing the same array. By creating an array factory that creates a single symbolic array, that problem is handled. Note: Concrete arrays should not be created by the factory method since their values are never shared between branches. The factory works by seeing if an array with a similar hash has been created before (the hash is based on the name and size of array). If there has been it then searches through all of the arrays with the same hash (stored in a vector) to see if there is one with an exact match. If there is one, the address of this previously created equivalent array is returned. Otherwise, the newly created array is unique, it is added to the map, and it's address is returned. This aliasing issue can be seen by comparing the output of the Dogfood/ImmutableSet.cpp test cases with and with out this commit. Both act correctly, but the number of queries making it to the solver in the previous version is much greater 244 vs 211. This is because the UBTree in the CexCachingSolver and the cache in the CachingSolver do not recognize queries whose solutions were previously calculated because it doesn't think the arrays in the two queries are the same. While this does not cause an error, it does mean that extra calls are made.
2014-11-01Upstream libstp is no longer dependent on Boost so remove theDan Liew
configure/Makefile code that adds Boost as a depdendency because We don't need to support old versions of STP that needed Boost.

2013-12-20Fix compilation of unittests under Clang.Dan Liew
It seems the GTest header file in LLVM 3.3 (and possibly other versions) makes use of typeid() but the build system passes -fno-rtti. These are incompatible and if building with Clang then compilation will fail. GCC doesn't seem to care!
