In a handcrafted case, one can make the body of quantified formula another quantified formula when special attributes are used. The relevant domain utility was not robust to this case, leading to instantiations with free variables.
This fixes the issue and also updates its style to use a term context stack, which also avoids a tree traversal of the bodies of quantified formulas in this utility.
Fixes #6476. The benchmark from that issue now times out.

This should be the last PR before quantifiers engine will not be passed to quantifiers modules.
|
|
|
|
Towards eliminating dependencies on quantifiers engine, and eliminating the TermUtil class.
Note that QuantifiersModule had to be moved to its own file to avoid circular include dependencies.
|
|
This refactors quantifiers so that it uses the standard interfaces for setting up an equality engine and using it via TheoryState.
This eliminates the need for several special interfaces including getMasterEqualityEngine, CombinationEngine::getCoreEqualityEngine, and most uses of EqualityQuery.

instead of answering unknown for benchmarks with quantifiers. Modified regressions accordingly. Minor fix for QCF regarding variable ordering. Improved relevant domain computation. Minor optimization for --mbqi=fmc
|

Use non-context dependent cache for instantiations when not incremental. Instantiate from relevant domain when no other instantiations apply. Minor cleanup of relevance for triggers.

just the header comments at the top, though. Don't update to this rev if
you don't have time for a complete rebuild, and exclude this rev if you
want to see what's new across a range of commits.
(this commit was certified error- and warning-free by the test-and-commit script.)

collectModelInfo with fullModel argument, most theory-specific implementation out of the model class, model printer relegated to printer classes. Also updates to finite mode finding, modifications to datatypes making them compatible with theory combination, support for theory-specific handling of user attributes, refactoring of uf models
|

src/theory/quantifiers and src/theory/rewriterules. This unclutters the src/theory directory somewhat.
The namespaces weren't changed, only the file locations.
|
|
* change some uses of "std::cout" to "Message()"
* change some files to use Unix newlines instead of DOS newlines
* fix compiler warning
|

(extended) SMT command get-model. added collectModelInfo and removed getValue from theory interface. merge also includes major updates to finite model finding module (from CASC), added fmf options, some updates to strong solver and quantifiers engine interface. The test recursion_breaker_black currently fails for me on production builds, Morgan is planning to look into this.
