dafny output as SMT file

问题

I successfully wrote a verified Dafny program that given an integer array, returns the length of the longest monotone prefix. The permalink is here. I want to be able to examine the SMT file Dafny used, even though there were no errors. I tried various flag options like:

$ dafny example_longest_monotone.dfy /useSmtOutputFormat /printModelToFile:smt_file.smt

But none seem to work? Am I wrong thinking that there must be some underlying SMT query that returned unsat in the case where Dafny succeeds?

回答1:

The command line flag to output the prover input is /proverLog:<file>.

You can also print the Boogie file that Dafny produces using /print:<file>.
