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

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

CArrayAccessor >> #long32At: "Why is this needed?"<br>
CArrayAccessor >> #long32At:put: "Why is this needed?"<br>

I am just guessing here, but I think that BitBltSimulator<br>
expects to<br>
be used with an interpreter simulator, so perhaps if you<br>
initialize it<br>
with a simulator there will be no need to add these methods.<br>
<br>
sim := BitBltSimulator new setInterpreter:<br>
InterpreterSimulator new<br>
<br>

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

Maybe it should be an InterpreterSimulator when simulating the whole interpreter. When calling #copyBitsSimulated, it is set to an InterpreterProxy in #copyBitsFrom: .<br>
<br>
Anyway, I'm asking for help on making #copyBitsSimulated work again, like it should do when called from BitBltTest. If nobody can help with that, I guess I'll open a Mantis issue for this problem, in the hope that some day it gets fixed.</blockquote>

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