10 years agosimplify mkSkolem naming system: don't use $$
Kshitij Bansal [Thu, 17 Apr 2014 17:03:30 +0000 (13:03 -0400)]
simplify mkSkolem naming system: don't use $$

Short summary: By default NODEID is appeneded, just continue doing what you
were, just don't add the _$$ at the end.

Long summary:

Before this commit there were four (yes!) ways to specify the names for new
skolems, which result in names as given below

1) mkSkolem("name", ..., SKOLEM_FLAG_DEFAULT)  -> "name_NODEID"
2) mkSkolem("name", ..., SKOLEM_EXACT_NAME)  -> "name"
3) mkSkolem("name_$$", ..., SKOLEM_FLAG_DEFAULT) -> "name_NODEID"
4) mkSkolem("na_$$_me", ..., SKOLEM_FLAG_DEFAULT) -> "na_NODEID_me"

After this commit, only 1) and 2) stay.

90% usage is of 1) or 3), which results in exact same behavior (and
looking at the source code it doesn't look like everyone realized that
the _$$ is just redundant).

Almost no one used 4), which is the only reason to even have $$. Post this
commit if you really want a number in the middle, manually construct the
name and use the SKOLEM_EXACT_NAME flag.

with different set of elements in the model for representative and the node
itself.

Issue:
  The trouble with data structure being mainted to ensure that things
for which lemmas have been generated are not generated again. This
data structure (d_pendingEverInserted) needs to be user context
dependent. The bug was in the sequence of steps from requesting that
a lemma be generated to when it actually was. Sequence was:
addToPending (and also adds to pending ever inserted) ->
isComplete (might remove things from pending if requirment met in other ways) ->
getLemma (actually generated the lemma, if requirement not already met)

Initial refactor of rewrite rules, make theory_rewriterules empty theory.  Push kinds to quantifiers/kinds, rewrite rewrite rules in rewriter.

Fix rewrite rule attribute, refactor QCF, instantiation engine does not register rewrite rules, minor clean up.

QCF is now functional backend to rewrite rules. Support boolean variables in QCF.  Change check-model to ignore rewrite rules.  Incorporate some fixes from master.

Move rewrite of rewrite rules from rewriter to preprocessor, attribute becomes pattern.

Minor fixes to QCF/rewrite engine, removes RE on last call approach.  Add option for one inst per round in RE.

Merging rewrite rules into master, check-model current fails on 3 FMF regressions.
