Arie Gurfinkel 1f6815213d spacer: fail with exception on quantifiers in recursive rules 2020-04-11 14:16:47 -04:00

Arie Gurfinkel f821ee38e5 Fix #3907 
Protect spacer from existential quantifiers in the tail.

Some transformations seem to introduce existentially quantified terms.

Arie Gurfinkel a261bd94ed silence #3788 
better proof generation for the case when the query is reachable from initial
states. This case needs to be handled better so that spacer can assume
the problem is non-trivial.

Arie Gurfinkel b1b77e57e1 (partial) fix #3788 
Fixes a bug in computation of implicants inside spacer.
The instance now returns `unknown`. The root cause is the difference in what
proofs are in spacer and SMT. Spacer returns a proof of query, but horn_tactic
expects a proof of FALSE.
