* | Dafny: added let expressions (syntax: "var x := E0; E1") | Rustan Leino | 2011-11-14 |
| | | | | | Dafny: firmed up semantics of assert/assume expressions (the condition is now good for all program control paths that pass through the expression) Dafny: various implementation clean-ups | ||

| | | | | | | operator on datatypes Dafny: allow the well-formedness check of a function's specification to know that the function, on the current arguments, returns a value of the declared result type | ||

* | Dafny induction: | Rustan Leino | 2011-10-29 |
| | | | | | | | * 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: removed Dafny's "foreach" statements (replaced by the new "parallel" ↵ | Rustan Leino | 2011-10-26 |

* | Dafny: check subrange restriction in parallel Assign statement | Rustan Leino | 2011-10-24 |
| | | | | | Dafny: verify parallel Call statement Dafny: fixed some bugs: handle all cases of comprehension expressions in resolver's UsesSpecFeatures, check target of method calls to be non-null (duh!) | ||
* | Dafny: continued translation of "parallel" statements (Assign and Proof ↵ | Rustan Leino | 2011-10-24 |

* | Dafny: changed triggers (which are never really used, anyhow) from having a ↵ | Rustan Leino | 2011-10-21 |
| | | | | | | | special syntactic form to being just an attribute Dafny: added "parallel" statement (so far, only parsing and resolving) Dafny: allow types on bound variables in "match" expressions/statements (there's never any incentive to list them explicitly in the program text, but it nevertheless seemed silly to forbid them) | ||
