@veanes
mk_bool_app_helper has a bug:
When it simplifies a disjunction or conjunction of regex membership constraints of the form (and (str.in_re "" R) (str.in_re x Q))
then the first term (str.in_re "" R) is omitted in the result.
You have a test here
3da9d91866/src/ast/rewriter/seq_rewriter.cpp (L438)
that means a regex membership with empty first argument is not put in the two buffers with membership/non-membership.
It isn't put into new_args either because the test bypasses these
3da9d91866/src/ast/rewriter/seq_rewriter.cpp (L485)

 2020-10-27 00:12:34 -07:00
Nikolaj Bjorner 3ba857fb04 add alternate caching mechanism to allow experimenting for #4747 
@nunoplopes @aqjune you can experiment by setting ALIVE_OPT to 1 and see if this helps.
A further possible optimization is to persist the "subst" object on the api_context object.
Then in Z3_substitute in api_ast.cpp, instead of declaring locally
        expr_safe_replace subst(m);
you can use an attribute on the context to retrieve the same substitution object.

fix bug in seq rewriter op_cache::find (#4509) 
* remove unneeded reverse case in derivative; placeholder for generalized lifted derivative

* experimental tweaks to RE rewriter to improve performance

* if-then-else lifting
(broken code -- preserving this commit in case this idea is useful later)

* if-then-else derivative optimizations: new approach templates

* implement if-then-else BDD normal form for derivatives
(code compiles but is still buggy)

* remove std::cout debugging for PR

* Revert "remove std::cout debugging for PR"

This reverts commit c7bdc44d31.

* debugging

* fix derivative interaction with reverse; add flags for left/right derivative and lifting over union/intersection

* remove debugging statements for PR

* Revert "remove debugging statements for PR"

This reverts commit 38e85a7288.

* revert some purely cosmetic changes from upstream; fix a bug

* revert unnecessary changes

* remove some redundant rewrites and add a new one for str.in_re(s, comp(r))

* add disabled rewrite for complement

* fix bug in op cache find (result was not saved)

* remove debugging std::cout for PR
