Reduce verbosity with model-gen about boolector

[sy6sy2]

So, I finally found the line to comment!
I comment this line

boolector/src/btormain.c

Line 1584 in d46fb7b

boolector_print_model (btor, val ? "smt2" : "btor", g_app->outfile);

and I now have the same behavior as CVC4 and Z3.

I also notice another "issue", when you have an SMT2 file without any (check-sat) (so only declare-fun, define-fun, assert), if you run this file with CVC4 or Z3 then you get nothing on your stdout (for me this is the correct behavior because you did not ask for a check-sat, a get-value or a get-model BUT, with boolector you get a sat or unsat line on your stdout, even without asking for a (check-sat).

This is expected behaviour. Boolector by default prints the full model (get-model) if option -m is provided. The default output language for the model is the BTOR format. Since you also query a value via (get-value) you get ((esi2 (_ bv8328 32))) followed by the full model in BTOR. Just use (set-option :produce-models true) in you SMT files and don't specify -m. There is no need to comment out code. Now you also disabled (get-model).

Boolector will still solve the problem even if there is no (check-sat) in the file. We can change this behaviour for SMT2 input files.

(set-option :produce-models true) is perfect!
Thank you very munch for your fast answer!
