Arie Gurfinkel 5a6bd5e782 hypothesis_reducer: worked around propositional literals 
propositional formulas (disjunctions) can appear as literals.  This

re-building unit resolution.

Added work-around that identifies whether a formula is a literal based
on its appearance in previous unit resolution step.

Arie Gurfinkel 9cdb63ae4a Handle conversion of quantified lemma to quantifier free 
When a cube is updated, a lemma might loose all of its quantified

and might be a version of an already existing lemma.

For that reason, we convert it to quantifier free lemma when
this happens.

Yakir Vizel 23a8e59493 Initial commit of QGen 
Controlled by fixedpoint.spacer.use_quanti_generalizer

measure cumulative time, number of invocations, and number of failed
SMT calls

Relaxing equality in a pattern: if a variable equals a numeral, relax with GE

pob::get_skolems() returns all skolems that might appear in the pob.
New skolems must be added above the largest index in that map,
even if they are not used in the pob itself.

pattern generalization should be done before the pattern is skolemized and
added into the new cube.

Arie Gurfinkel b8b3703511 improved implementation of is_qblocked() 
Disabled by default. Has no effect if ran with the default set of

Arie Gurfinkel 371ba4fbc0 added parameters that seem to work well with quantifiers and arith 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 27d8fa4a34 hard-code quantifier weight to 15 
With default settings, the eager threshold is 10 and lazy is 20.  15
puts us in the middle ensuring that lemmas are instantiated when UNSAT
and otherwise delayed.
 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 135a4a765f Adding grounding of the current lemma 
In addition to adding the necessary instance of a quantified lemma,
add its grounding over the global set of skolems.

Arie Gurfinkel 6cf68bee80 app ordering that puts special skolem constants first 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 9f0eb367b1 ground lemmas during propagation when qlemmas are disabled 
When asserting quantified lemmas are disabled, ground a lemma
explicitly during propagate to make sure that it is ground using our
local set of skolem constants.
 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 5da0753269 (spacer) add instances even when a q-lemma already exists 
It is possible that a new instance of a quantified lemma is discovered
even though a quantified lemma it already known. In this case, the
instance should be added to a corresponding context, even though the
lemma is not new.

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.

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.
