Z3str3 Debug (#6000) 
* z3str3 debug

* add comments of reference to bugs in the report

Co-authored-by: John Lu <z52lu@uwaterloo.ca>
 2022-04-27 12:37:07 +02:00
Nikolaj Bjorner 81d97a81af enable nested ADT and sequences 
add API to define forward reference to recursively defined datatype.
The forward reference should be used only when passed to constructor declarations that are used in a datatype definition (Z3_mk_datatypes). The call to Z3_mk_datatypes ensures that the forward reference can be resolved with respect to constructors.

Nikolaj Bjorner 87d4ce2659 working on #5614 
there are some different sources for the performance regression illustrated by the example. The mitigations will be enabled separately:
- m_bv_to_propagate is too expensive
- lp_bound_propagator misses equalities in two different ways:
   - it resets row checks after backtracking even though they could still propagate
   - it misses equalities for fixed rows when the fixed constant value does not correspond to a fixed variable.

FYI @levnach

Nikolaj Bjorner 09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).
