This eliminates some hacks for dealing with Int/Real.
- Eliminates the use of "to_real" to cast decimals like "2.0" that happen to be Int. We now replace these by (/ 2 1) instead of (to_real 2), which has the advantage of being smt-lib compliant for all theories, including QF_LRA.
- Eliminates the use of a hack to use "type ascriptions" when returning values from a get-value command. Instead, we use division with 1 when necessary. This affects the output of a few regressions, but we remain smt-lib compliant.
- Addresses a bug with printing arbitrary type ascriptions for smt2 terms. This partially addresses #1852.
- Updates our printing of negative rationals to be (/ (- n) m) instead of (- (/ n m)), which is consistent with the smt lib standard for real values (http://smtlib.cs.uiowa.edu/theories-Reals.shtml).

The SMT2 parser by default passes a true expression to the CheckSatCommand,
which results in checkSatisfiability (in SmtEngine) to always do an internal
push. As a consequence, the work of each check-sat was reset even though no
user level push/pop happened.

* 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

Logic enum with an UNSET value. (#1329)
|
|
* Removing an unused member from Tptp. Initializing members of Tptp.
* Removing delcaration for myPopCharStream.
|
|
* Make higher-order a flag in logic info.
* Format
* Minor
* Format
|
|
* Support SAT logic.
* Add lustre example.
* Add to smt1 as well.
* Fix.
* Fix.
* Fix for new option.

* Use uintptr_t for pointer casts in Swig files
CVC4's Swig interface files were casting pointers to longs in multiple
instances. The problem with that is that on certain platforms *cough*
Windows/MinGW *cough* long is only 32-bit even when compiling a 64-bit
executable (they use the LLP64 data model). This made the compilation of
language bindings fail with MinGW. This commit changes the types to
uintptr_t defined in Swig's stdint.i.
* Modify LDFLAGS to support shared libraries for Win
This commit adds "-no-undefined" to the LDFLAGS of CVC4's library, which
is required for building DLLs (shared libraries on Windows). It also
adds "--export-all-symbols" to the linker flags of the parser to ensure
that there are no unresolved symbols when linking against it (see
comment in the Makefile.am for details).
* Fix for non-Windows builds
* add no-undefined to libcvc4compatjni
|
|
* Represent sygus synthesis conjectures using higher-order quantification, remove associated hacks.
* Minor fix
* Fix bug in Node::hasBoundVar for non-ground operators.
* Add regression.
* Address review.
* Apply clang format.
|
|
* Support unsat cores for TPTP.
* Fix assertion
|
|
* Argument for strings class to specify whether to process escape sequences.
* Change default value on string constructor.
* Make CVC4::String::toString symmetric to the constructor for CVC4::String, document.
* Clang format.
|
|
* Allow any smt2 logic to be a sygus logic. Add non-linear SyGuS regressions.
* Minor
* Add case for reals, comment.
* Fix regress1.
|
|
* Move unsat core names to SmtEnginePrivate. Adds a SetExpressionNameCommand to do this. Removes the names field from GetUnsatCoreCommand.
* Comment
* Pass expression names by reference.
* Update throw specifiers.
* Minor
* Switch expression names to CDMap, simplify interface for printing unsat core names.
* Revert throw specifier change.
* Minor simplifcations
|
|
* Move equality query to own file, move equality inference to quantifiers engine.
* Move quantifiers attributes out of TermDb and into QuantAttribute.
* Move term database sygus to quantifiers engine, move some attributes to quantifiers attributes header.
* Split term database into term util.
* Partial fix for #1205 that eliminates need for dependency in node.cpp.
* Add more references to github issues.
