This moves all generic proof utilites from src/expr/ and src/theory/ to src/proof/.
It also changes the include for term conversion proof generator to conv_proof_generator in preparation to rename this utility on a followup PR (to avoid confusion with the use of "Term").

Eliminates NodeHashFunction, TNodeHashFunction and TypeNodeHashFunction.

This is in preparation for refactoring skolem creation throughout the code base to improve proofs and migrate Theory::expandDefinitions to Rewriter::expandDefinitions.
This PR also eliminates some unused code in TheoryArithPrivate.
Followup PRs will start formalizing/eliminating calls to mkDummySkolem.

Currently, NodeBuilder takes a single template argument: An integer
that determines the expected number of arguments. This argument is used
to determine the size of the d_inlineNvChildSpace array. This array is
used to construct nodes inline. The advantage of this is that we don't
have to allocate a NodeValue on the heap for the node under
construction until we are sure that the node is new. While templating
the array size may save some stack space (or avoid a heap allocation if
we statically know that we a fixed number of children and that number is
greater than 10), it complicates the code and leads to longer compile
times. Thus, this commit removes the template argument and moves some of
the NodeBuilder code to a source file for faster compilation.

(#6240)
This completes eliminating dependencies on quantifiers engine from internal quantifiers code. It eliminates quantifiers_engine.h as an include from src/theory/quantifiers/ apart from theory_quantifiers.cpp where it is owned.
Followup PRs will further eliminate circular dependencies that arose will refactoring quantifiers engine.

This PR cleans up a ton of includes, based on the suggestions of iwyu.
Mostly, it removes includes from header files in favor of forward declarations and adds includes to source files.

This eliminates the need for direct references to TheoryEngine from quantifiers and UF+cardinality.
This PR also eliminates an unnecessary reference to TheoryEngine in TheoryModelBuilder and breaks a few more dependencies in quantifiers modules.
|
|
In particular, theory_engine.h is included many places spuriously.
A few blocks of code changed indentation, updated to guidelines.

(#5814)
This makes printing instantiations done at the SmtEngine level instead of deeply embedded within the Instantiate module. This provides much better flexibility for future uses of instantiations (e.g. how they are minimized in the new proof infrastructure).
Note this PR breaks the functionality that instantiations are minimized based on the old unsat cores infrastructure (see the disabled regression). This will be fixed once proof-new is fully merged.

This is a step towards breaking up the quantifiers engine.
The key change is that QuantifiersEngine will not be passed as a pointer to the modules it contains. This PR makes it so that necessary modules take a QuantifiersState, which will eventually be extended as needed with additional query methods. For now, modules will take both until the dependencies on QuantifersEngine are removed.
This required that QuantifiersEngine now lives in TheoryQuantifiers, instead of in TheoryEngine, since the QuantifiersEngine must be initialized with QuantifiersState, which is a member of TheoryQuantifiers. Now, TheoryEngine retrieves the QuantifiersEngine from TheoryQuantifiers prior to finishing initialization on theories.

This adds support for proofs in the quantifiers module that performs skolemization.
Also fixes a bug in the proof checker for skolemization.

This PR updates the update-copyright.pl script to also update/add copyright headers to CMake specific files. It further fixes a small typo in the header.
