* | Dafny: added let expressions (syntax: "var x := E0; E1") | 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 | ||

| | | | | | | only applied to values created by the corresponding constructor Dafny: implement ghost destructors properly | ||

* | Dafny: added assert/assume expressions | 2011-11-09 | |

* | Dafny induction: | 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: allow attributes on function/method declarations to refer to the (in- ↵ | 2011-10-26 | |
| | | | | and out-)parameters | ||
* | Dafny: removed Dafny's "foreach" statements (replaced by the new "parallel" ↵ | 2011-10-26 | |
| | | | | statement) | ||
* | Dafny: removed support for assigning to an array-range (that is, an ↵ | 2011-10-26 | |
| | | | | assignment statement where the LHS has the form a[lo..hi]) | ||
* | BVD: fixed two basic but damning problems with the Dafny provider, and ↵ | 2011-10-26 | |
| | | | | elided some temporary variables | ||

| | | | | Dafny: beefed up resolution of parallel statements | ||
* | Dafny: check subrange restriction in parallel Assign statement | 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 ↵ | 2011-10-24 | |
| | | | | | | | forms are mostly there, Call is missing and so is compilation) Dafny: included some test cases for the "parallel" statement Dafny: starting changing old "foreach" statements to the new "parallel" statement | ||
* | Dafny: added translation of Assign case of the parallel statement | 2011-10-22 | |
| | | | | Dafny: discovered and fixed bug in no-overlap check of multi-dimensional array update, and changed previously incorrect MatrixFun.dfy test case (the new version is also a more efficient program) | ||
* | Dafny: changed triggers (which are never really used, anyhow) from having a ↵ | 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) | ||
* | Dafny: fixed performance-buggy translation of exists, and also added some ↵ | 2011-10-19 | |
| | | | | other features in SplitExpr (such as induction on existential quantifiers) | ||

| | | | | | | | | Dafny: don't compile programs unless all methods have been verified (or a forced compile is requested) | ||
* | | Dafny: fixed compilation bug (datatype equality had used pointer equality, ↵ | 2011-09-11 | |
| | | | | | | | | not member equality) | ||
