* Stop pretty-print from emitting deprecated semi-colons.Gravatar qunyanm2015-03-05

* Language change: All functions and methods declared lexically outside any ↵Gravatar leino2014-12-12
| | | | | | | | | | class are now automatically static, and fields are no longer allowed to be declared there. Stated differently, all heap state must now be declared inside an explicitly declared class, and functions and methods declared outside any class can be viewed as belonging to the module. The motivating benefit of this change is to no longer need the 'static' keyword when declaring a module of functions and methods.

* Renamed "parallel" statement to "forall" statement, and made the parentheses ↵Gravatar Rustan Leino2013-03-06

* Dafny: removed Dafny's "foreach" statements (replaced by the new "parallel" ↵Gravatar Rustan Leino2011-10-26

| | | | | | | | | | * started rewriting parsing of qualified identifiers in expressions * annoyingly, had to introduce AST nodes for concrete syntax * previous syntax for invoking datatype constructors: #List.Cons(h, t) new syntax: List.Cons(h, t) or, if only one datatype has a constructor named Cons: Cons(h, t) * Removed type parameters for datatype constructors from the grammar * Helped Test/VSI-Benchmarks/b4.dfy along with a couple of assertions (previously, its proving performance was highly varied)

* Big change: Add type and allocatedness information everywhere in the Boogie translation. This not only fixes some potential soundness problems (see Test/dafny1/TypeAntecedents.dfy), but it also gives more information about the program. On the downside, it also requires discharging more antecedents in order to use some axioms. Another downside is that overall performance has gone down (however, this may be just an indirect consequence of the change, as it was in one investigated case). * Increase the applicability of function axioms (extending the coarse-grain function/module height mechanism used as an antecedent of function axioms). (Internally, this uses the new canCall mechanism.) * Extend language with "allocated( Expr )" expressions, which for any type of expression "Expr" says that "Expr" is allocated and has the expected type. * More details error messages about ill-defined expressions (internally, by using CheckWellformedness instead of "assert IsTotal") * Add axioms about idempotence of set union and intersection * The compiler does not support (the experimental feature) coupling invariants, so generate error if the compiler ever gets one * In the implementation, combine common behavior of MatchCaseStmt and MatchCaseExpr into a superclass MatchCase * Fixed error in translation of while(*)
