* Added some Dafny and Boogie test cases, including Turing's factorial ↵Gravatar Rustan Leino2011-11-03

* Dafny induction:Gravatar Rustan Leino2011-10-29
| | | | | | | * implemented induction tactic for result-less, non-mutating ghost methods * refine heuristics for determining if a variables is usefully passed to a recursive function * disallow certain "ensures" to use two-state features (needed for soundness of the parallel-statement translation, see comments in Resolver.cs and ParallelResolveErrors.dfy) * added command-line flags /induction and /inductionHeuristic (everything is on by default)
* Dafny: continued translation of "parallel" statements (Assign and Proof ↵Gravatar Rustan Leino2011-10-24
