| * | Moved the statement traverser's operand stack (used for explicit push/pop/dupGravatar Unknown2012-09-09
|/ / | | | | | | | | | | | | | | | | | | in the code model) into the sink so that the different statement traversers used for things like if-then-else statements share the same stack. Fixed a problem in the dispatch table for whole program virtual dispatch so it works for generic methods. Found input that either crashed the translator or caused it to produce bad Boogie: "fixed" it by having the translator thrown an exception so the method containing the bad code is skipped.

| | | | | | | | | | | | | | | | | | | | | | Improved loop invariant inference so that procedure formal parameters are treated as constants. (This involved fixing a bug where a Formal was being dualised to a LocalVariable.) Fixed problem in GPUVerifyBoogieDriver where source location information was being looked for via a file name, rather than a full path. Cleaned up some code in GPUVerifyBoogieDriver.

* Fix the whole-program translator so that exception handling is doneGravatar Unknown2012-08-23
| | | | | | | | | | correctly for virtual method calls. Changed the whole-program override for VisitMethodCall so that it creates a new CodeModel expression that does not contain virtual method calls and then translate that newly built expression. Treat type equality (and inequality) specially: translate it directly to a type test instead. But do it just for the idiom: "o.GetType == typeof(T)". In that case, turn it into "is#T$T($DynamicType(o))".
* Make the modelExceptions option an integer.Gravatar Unknown2012-08-22
| | | | | | | | | | | | | | | 0 means no modeling at all. 1 (which can be specified only if also specifying whole program translation) means that a fixpoint analysis will be done on all of the translated assemblies to compute the set of exceptions that each method can throw (even though we're using only the fact that a method throws anything at all, not the specific exceptions it can throw) so only calls to methods that can throw an exception have a branch after the call that checks to see if an exception has been thrown. Methods that are defined outside of the set of translated assemblies are assumed to *not* throw any exceptions! 2 means that every method is considered to be one that can throw an exception.
