Merge pull request #1606 from NikolajBjorner/opt 
This integrates several features and improvements to the SAT and finite domain solver.

- The SAT solver by default handle cardinality and PB constraints using a custom plugin that operates directly on cardinality and PB constraints.
- A parallel mode is available for select theories, including QF_BV. By setting parallel.enable=true Z3 will spawn a number of worker threads proportional to the number of available CPU cores to apply cube and conquer solving on the goal.
- A "cube" interface is exposed over the solver API. 
- Model conversion is first class over the textual API, such that subgoals created from running a solver can be passed in text files and a model for the original formula can be recreated from the result.
- This has also led to changes in how models are tracked over tactic subgoals. The API for extracting models from apply_result have been replaced.
- An optional mode handles xor constraints using a custom xor propagator. It is off by default and its value not demonstrated.
- The SAT solver includes new inprocessing technques that are available during simplification. It performs asymmetric tautology elimination by default, and one can turn on more powerful inprocessing techniques (known as ACCE, ABCE, CCE). Asymmetric branching also uses features introduced in Lingeling by exploiting binary implication graphs.

- A breaking change to the API is that parsers for SMT-LIB2 formulas return a vector of formulas as opposed to a conjunction of formulas. The vector of formulas correspond to the set of "assert" instructions in the SMT-LIB input.

Dan Liew 229fd3dc3e [CMake] Fix dependencies for generating install_tactic.cpp. 
Previously CMake was not aware of which headers files the generation
of `install_tactic.cpp` depended on. Consequently this could result
in broken incremental builds if

* Existing headers that declared tactics/probes changed.
* New tactics/probes were added to new header files.

Now the `z3_add_component()` CMake function has been modifed to take an
optional `TACTIC_HEADERS` argument which allows the headers that declare
tactics/probes to be explicitly listed. The necessary component
declarations have been modified to declare their tactic/probe header
files.

With this information CMake will now regenerate `install_tactic.cpp`
correctly.

This required the `mk_install_tactic_cpp_internal()` function to be
changed to take a list of header files rather than a list of component
source directories. The two consumers (CMake and Python/Makefile build
systems) of this function have been modified to work with this change.

This partially fixes #1030.
 2017-06-21 23:03:48 +01:00
Dan Liew 4b517b96df [CMake] Move CMake files into their intended location so the 
`contrib/cmake/bootstrap.py` script no longer needs to be executed.

The previous location of the CMake files was a compromise proposed
by @agurfinkel in #461. While this has served us well (allowing progress
to be made) over time limitations of this approach have appeared.

The main problem is that doing many git operations (e.g. pull, rebase)
means the CMake files don't get updated unless the user remembers to
run the script. This can lead to broken and confusing build system
behaviour.

This commit only does the file moving and necessary changes to
`.gitignore`. Other changes will be done in subsequent commits.
