This PR does some more cleanup of the includes.
|
|
|
|
Similar to #6031, this PR implements suggestions from iwyu to reduce the number of includes in header files by introducing forward declarations and moving includes to source files.

Now the old proofs are used for unsat cores only if proofNew is disabled. Later commits will generate unsat cores from the new proofs when requested. Eventually we will compare them and when we confirm the new unsat core generation is better we will delete the old one.
This also does some minor refactoring in some preprocessing. No behavior is changed.

Ensuring closed proofs should not be enabled by default, it is actually not used very often as a whole. Moreover, the "trust id" argument is the most useful argument and hence should come as the 3rd argument. This updates all uses of addLazyStep for the change in interface, also changes term conversion generator which had a similar issue with default arguments.
Notice that some calls to addLazyStep were checking closed but without providing a debug string, these I've left alone (they no longer check closed).

This updates and improves assertions pipeline and preprocess generator so that they avoid cyclic proofs and have better infrastructure for catching pedantic failures.
This is in preparation for making the non-clausal-simplification pass proof producing.

This sets up the preprocessing pass context in preparation for proof production.
This PR makes the top level substitutions map into a TrustSubstitutionMap, the data structure that applies substitutions in a way that tracks proofs.
This PR also makes the "apply subst" preprocessing pass proof producing.

pipeline (#5136)
This PR makes several fixes to preprocess proof generator, making it user-context dependent and making it avoid cyclic proofs. It additionally makes assertion pipeline a new interface "conjoin" which should always be used when we conjoin a new assertion to an old position in the assertion vector. It also removes an unnecessary interface to assertion pipeline.
Next PRs will clean up the use of assertions pipeline in all preprocessing passes to use the proper interfaces. This includes removing non-constant references to assertions, which has been fixed on proof-new.

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.

This module is responsible for constructing the proof checker, proof node manager, and implementing dumping and checking of the final proof.
This PR includes setting up some connections into the various modules for proof production.

This deletes much of the old proof code. Basically everything but the minimal necessary infra-structure for producing unsat cores. That includes dependency tracking in preprocessing, the prop engine proof and the unsat core computation code in the old proof manager. These should also go once we fully integrate into master the new proof infrastructure.
It also cleans interfaces that were using old-proof-code-specific constructs (such as LemmaProofRecipe). When possible or when it made sense standalone local proof production code was kept, but deactivated (such is in the equality engine and in the arithmetic solver).

Adds explicit steps to preprocess proof generator if one is provided.

When we do solving in incremental mode, we store substitutions at a
special index in our list of assertions. Previously, we used a
context-dependent variable for that. However, this is not needed since
the list of assertions just consists of the assertions currently being
processed, which are independent of the assertions seen so far. This
commit changes the index to be an ordinary integer and moves it to the
AssertionPipeline. Additionally, it abstracts access to the index in
preparation for splitting AssertionPipeline into three vectors (see
issue #2473).

Before refactoring the preprocessing passes, we were using three
arguments to add assertions to the decision engine. Now all that
information lives in the AssertionPipeline. This commit moves the
AssertionPipeline to its own file and changes the `addAssertions()`
methods related to the decision engine to take an AssertionPipeline as
an arguement instead of three separate ones. Additionally, the
TheoryEngine now uses an AssertionPipeline for lemmas.
