* Fixes --hide-zero-stats (and really skips the 0 values)
* Removes the additional newline after each statistic
* Introduces theory::getStatsPrefix(TheoryId) to generate consistent
prefixes for statistics based on the theory id
(e.g., THEORY_BV -> "theory::bv").

Adds missing override keywords.

This adds support for check-sat-assuming. It further adds support for SmtEngine::query() over a
vector of Expressions, e.g., smtEngine->query({a, b}); checks the validity (of the current input
formula) under assumption (not (or a b)).
|

|
Also adds parsing support for PI in smt2 with syntax "real.pi".

This commit fixes two issues with reset-assertions:
- pending pops were not done in SmtEngine, resulting in the following
assertion failure:
d_userLevels.size() == 0 && d_userContext->getLevel() == 1
- all definitions were erased on reset-assertion in an SMT2 file,
leading to errors about undefined types

This ensures a single success is printed for synth-fun and synth-inv. (#1193)
|

* Update parser for operator overloading.
* Improvements
* Updates
* Add assert

|
- Update the parser to the new constant construction
- Fix the problem with parsing +/-zero and remove some dead code
- Extend the interface for literal floating-point values.
- Add a constructor so that a parameteric operator structure can be created from a type
- Add constructors so parametric operator constants can be easily converted
- Update SMT2 printing so that it uses the informative output

* Remove unhandled subtypes, which consequently makes typing rules uniformly stricter based on weakening the subtype relation. Ensure coercions in the smt2 and cvc parser for Real decimal constants whose type is Integer. Ensure type annotations are computed during preRewrite to ensure rewriting (which does not preserve types) does not impact term construction for parametric datatypes. This fixes issue #1048 (we now give an type exception).
* Update unit test for parametric datatypes to reflect new subtyping relation.
* Remove deprecated test.
* Make array construction for lambdas work with new subtype relations to handle lambdas like (lambda ((x Int) (y Int)) (ite (= x 0) 0.5 0.0)).
|
|
* Remove support for conversions between uint32/uint16 and string.
* Temporarily disable regression.

Algorithm was previously removed from src/util/regexp.h which broke
compilation on some platforms.

sygus), update regressions.

* Replacing __gnu_cxx::hash_map with std::unordered_map.
* Replacing __gnu_cxx::hash_set with std::unordered_set.
* Replacing __gnu_cxx::hash with std::hash.
* Adding missing includes.

With C++11, we don't need PtrCloser anymore because we can
just use std::unique_ptr.

ANTLR generates C files that we compile with the C++ compiler.
To do so, we set CC=CXX in the `Makefile.am`s of the parsers.
Previously, we did not copy the CXXFLAGS to the CFLAGS, which
could result in problems, e.g. when using -std=gnu++11 in the
CXXFLAGS, compiling the parsers would fail if they used C++11
features (configure.ac usually modifies CXX to include the
-std=gnu++11 flag but if it is included in CXXFLAGS, the CXX
is not changed).

of non-linear extension. Add factoring lemma scheme for non-linear. Add regressions.

decision procedure to share selectors of the same type across multiple constructors. Major rewrite of the SyGuS solver. Adds several new strategies for I/O example problems (PBE) and invariant synthesis. Major simplifications to sygus parsing and synthesis conjecture representation. Do not support check-synth in portfolio. Add sygus regressions.

In SMT 2.6, Datatypes are being introduced and they come
with testers (indexed identifier of the form (_ is c)) and
match expressions. This lead to failures in UFIDL
benchmarks in SMT-LIB because they declare the function
'is'. This commit changes the parser s.t. it does not
consider 'is' and 'match' special tokens unless the theory
of datatypes is enabled.
|
|
This commit addresses bug 807. CVC4 was parsing floating-point related tokens
such as NaN as floating-point tokens even for inputs that do not use the FP
theory, which lead to failing SMT-LIB benchmarks that declare functions named
NaN.
