This updates option names to be consistent across uses of counterexample-guided quantifier instantiation (ceqgi), which was previously called "counterexample-based quantifier instantiation" (cbqi), and sygus.
Notably, the trace "cegqi-engine" is changed to "sygus-engine" by this commit.
The changes were done by these commands in the given directories:
src/:
for f in $(find -name '.'); do sed -i 's/options::cbqi/options::cegqi/g' $f;sed -i 's/cegqi-engine/sygus-engine/g' $f; done;sed -i 's/"cbqi/"cegqi/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/--cbqi/--cegqi/g' $f; done
src/: and test/regress/:
for f in $(find -name '.'); do sed -i 's/cegqi-si/sygus-si/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/no-cbqi/no-cegqi/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/:cbqi/:cegqi/g' $f; done
And a few minor fixes afterwards.
This should be merged close to the time of the next stable release.

A recent change made it so that defined functions would print as the anonymous lambda corresponding to their definition if the SyGuS v1 parser was used. This was caused by comparison with the wrong kind in the new API.
Notice that the v2 parser does not have this issue.
This also adds a regression to ensure this behavior is maintained by the SyGuS v2 parser.

Fixes #3645.

Towards v1 -> v2 sygus conversion.
This makes several fixes and improvements related to printing sygus commands:
(1) The logic is extended with LIA, DT, UF internally during setDefaults instead of during parsing. This is the correct place for this extension of the logic since it should be applied regardless of the parser. 5 existing logic bugs were discovered as a result of this in regressions, which are fixed by this PR.
(2) Ensures that terms in sygus grammars are printed without letification, since this is prohibited in sygus. Notice the formulas printed by constraints need to be letified (otherwise we can't convert large lustre benchmarks). Thus, the letification threshold should determine this but always be overridden for grammar terms.
(3) Ensures final options are set for all sygus-specific commands, which follows the standards prescribed by sygus v2 (all set-* commands come before other commands).

PR #3388 didn't disable the regression correctly (due to using `REQUIRE`
instead of `REQUIRES`). This commit fixes the issue.

This commit disables a regression test that was failing for the
competition build due to not emitting the expected error message.

This makes `--sygus-inference` a no-op for inputs where there is a free function whose sort cannot be handled in a sygus grammar.
It also fixes an issue where skolem variables were not being treated as functions-to-synthesize.
Fixes #3250 and fixes #3356.

This short circuits CEGQI when the conjecture is solvable by simple equality reasoning. It adds two examples where we previously would have fallen back on enumeration due to not having an instantiation technique for strings, despite the conjectures being trivially solvable.

Recognizes when the conjecture has conflicting I/O pairs. Also includes a minor change to the default behavior of PBE.
This change broke a delicate regression array_search_2, which I fixed by adding some additional options to make it more robust.
After this PR, we immediately find 4/7 unsolved in PBE strings of sygusComp 2018 to be infeasible.

* Fix file extension
* Update Makefile
|
|
|
|
Until now, regression tests were split across tens of different
Makefile.am, which required a lot of code duplication and does not
really seem to be in the spirit of automake. If we want to change the
LOG_COMPILER/LOG_DRIVER for example, we have to change every single
Makefile.am, which is cumbersome (I was able to get something
semi-working by exporting those variables but it didn't seem very
clean). Additionally, it made the output of the regression tests fairly
verbose and split the output across multiple log files. Finally
it also limited parallelism when running the regression tests (this fix lowers
the time it takes to run regression level 1 from 3m to 1m45s on my
machine with 16 threads).
This commit moves all the regression tests into
test/regress/Makefile.tests and changes test/regress/Makefile.am to deal
with this new structure. Finally, it changes how the test summary in
test/Makefile.am is produced: instead of relying on the log files for
the subdirectories, it greps for the test results in the log files of
the individual tests. Not the most elegant solution but we should
probably anyway delegate that task to a Python script at some point.

This refactors and simplifies solveBvLit() and fixes the following:
- generate side conditions for BITVECTOR_NEG, BITVECTOR_NOT, BITVECTOR_PLUS,
BITVECTOR_XOR over inequalities and disequality
- fix CONCAT handling (generate side conditions rather then computing an inverse which was incorrect)
- fix SIGN_EXTEND handling (same as with CONCATs)
