* Changed "dummy" checksums to "stable" and added more tests for the ↵Gravatar wuestholz2014-07-03
| | | | verification result caching.
* Added support for verifying Dafny program snapshots from the command-line.Gravatar wuestholz2014-07-01
|
* Added tuples and tuple types. Syntax is the expected one, namely parentheses ↵Gravatar Rustan Leino2014-06-27
| | | | around a comma-delimited list of expressions or types. Unit and the unit type are denoted ().
* Make syntax of "match" expressions and "match" statements the same -- curly ↵Gravatar Rustan Leino2014-06-24
| | | | braces around the cases are now supported for both and are optional for both
* Invert LHS sub-expressions in forall assignment statements, which gives the ↵Gravatar Rustan Leino2014-06-24
| | | | opportunity to designate a good trigger.
* Specialized Lit function for int and real (leaving all other cases ↵Gravatar Rustan Leino2014-06-10
| | | | | | polymorphic). This reduces the number of int<->U conversions that Boogie adds, which avoids a looping problem in Z3. (Regrettably, the test suite seems to have become rather unstable. Sometimes everything verifies and sometimes there is some looping forever.)
* Fixed issues with absolute file names in the expected output for the lit tests.Gravatar wuestholz2014-06-04
|
* Added support for 'dirty' forall statements.Gravatar chmaria2014-06-03
| | | | | | | | | | | One can now write forall statements without bodies (but with ensures clauses) as follows: forall s | s in S ensures s < 0; where S is set<int>. The ensures clauses are assumed but not checked.
* Set up the same test infrastructure as in Boogie.Gravatar wuestholz2014-05-29
|
* Fixed bug in resolution, where type proxies involved in equality tests did ↵Gravatar Rustan Leino2014-05-07
| | | | | | not get assigned. (Issue #35) Fixed Main detection--a method "Main" with type parameters cannot be a program entry point.
* Fixed some bugs where various attributes were not properly visited during ↵Gravatar Rustan Leino2014-05-05
| | | | type checking.

* Members included from different files are now internally marked with an ↵Gravatar Rustan Leino2014-04-19
| | | | | | | IncludeToken; the previous scheme of using {:verify false} is no longer used. This makes "include" work with refinement features. Filenames of included files used in error messages are now what the user wrote, rather than absolute paths (which not only don't look so good, but are also problematic in comparing test output on different machines). Added dafny0/Includee.dfy to the test suite as well -- might as well include it, too, to get checked.
