Hi Folks,

I've just opened http://bugs.squeak.org/view.php?id=7407 , with a description of the problem, several tests (based on Henrik's scripts) and the fix I propose.

What worries me a bit is the other changes I needed to do to be able to run the Smalltalk BitBlt simulation and to do the translation. These are:

I am just guessing here, but I think that BitBltSimulator expects to
be used with an interpreter simulator, so perhaps if you initialize it
with a simulator there will be no need to add these methods.

 sim := BitBltSimulator new setInterpreter: InterpreterSimulator new

Given that BitBltSimulation calls #isIntegerObject: it looks like the ivar interpreterProxy should hold an InterpreterProxy (as it already does) and not an InterpreterSimulator. I did not add my patch to make simulation work to Mantis, as I'm not sure about them.

Andreas, perhaps you (or anyone knowledgeable enough) can try making the bitblt simulator tests included in the Mantis issues work. BTW, I moved these tests to VMMaker, as the current version in trunk does test nothing if VMMaker is not loaded. That's why these old tests didn't catch the problem of BitBltSimulator not working anymore.

Cheers,
