description (it was implemented in VCC before and is quite useful).

* Updated Parser.cs/Scanner.cs to use new .frame files from boogiepartners.
* It changes, for example, "syntax error:" to just "error:", so adjusted expected Test outputs.
Dafny:
* Ditto for its Parser.cs/Scanner.cs.
* Added ability to provide a custom Errors handler for scanner/parser.
* Added Test/dafny1/Cubes.dfy
|

|
|
|
|
|
|
| |
* Added internal support for multi-dimensional arrays (but not all surface syntax is there yet)
* Removed unused variables from Dafny.atg
Boogie and Dafny:
* Improved error message for postcondition violations

TypeToString() instead. Add test for /typeEncoding:m.
|
| |
|
|
|
|
|
|
|
|
| |
* Added support for polymorphism in lambda expressions
* Little clean-up here and there
* Added 'then' keyword to emacs and latex modes
Dafny:
* Added support for fine-grained framing, using the back-tick syntax from Region Logic
* Internally, changed checking of reads clauses to use a local variable $_Frame, analogous to the $_Frame variable used in checking modifies clauses

missing)
Boogie: Added {:subsumption <n>} attribute to assert statements, which overrides the /subsumption command-line setting

* Bug fix: Changed checking of postconditions to follow the order in which ensures clauses are given (not reverse order, as was previously the case)
* Added command-line option (/instrumentInfer) that decides how to instrument the Boogie program with inferred invariants. Previously, the only option was to instrument at the beginning and end of every basic block. The new option, which is now the default, is to instrument only at the beginning of loop heads.
* Add empty blocks between other blocks only as needed, and try a little harder to retain source information when blocks are peep-hole optimized
* Renamed flag /noRemoveEmptyBlocks to /removeEmptyBlocks:<c> where <c> is 0 or 1
Boogie refactoring:
* Removed LoopPredicate class and related classes and methods left over from when (back in the Zap 2 days) we supported loop invariants on demand
* Cleaned up some parsing of command-line options

Controlled by the option /coalesceBlocks (default is to perform the optimization).
