* Change the return type of StandardVisitor.VisitLiteralExpr() fromGravatar Dan Liew2015-01-25
| | | | | | | | | | | | | LiteralExpr to Expr. Enforcing the return type be LiteralExpr is too restrictive. There is precedence for this. For example VisitNAryExpr() returns an Expr not an NAryExpr. Unfortunately this a breaking API change so anyone who subclasses the StandardVisitor (or one of its sub classes) and overrides this method will get compilation errors until they change the return type. a visitor that does constant folding of an Expr tree

| | | | | | | | | | | | | | ExistsExpr to Expr. Enforcing the return type be ExistsExpr is too restrictive. For example it prevents anyone from implementing a visitor that does constant folding of an Expr tree. There is precedence for this. For example VisitNAryExpr() returns an Expr not an NAryExpr.

* Fix nasty bug introduced by commit 61a94f409975.Gravatar Dan Liew2014-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were many calls in the code to ``` new TokenTextWriter("<buffer>", buffer, false) ``` Prior to 61a94f409975 this was a call to the following constructor ``` TokenTextWriter(string filename, TextWriter writer, bool setTokens) ``` After that commit these then became calls to ``` TokenTextWriter(string filename, TextWriter writer, bool pretty) ``` An example of where this would cause issues was if ToString() was called on an AbsyCmd then the its token would be modified because the setTokens parameter was effectively set to True when the original intention was for it to be set to false! To fix this I've * Removed the default parameter value for pretty and fixed all uses so that we pass false where it was implicitly being set before * Where the intention was to set setTokens to false this has been fixed so it is actually set to false! Unfortunately I couldn't find a way of observing this bug from the Boogie executable so I couldn't create a test case. I could only observe it when I was using Boogie's APIs.
