I can confirm building a VM from the ClosureVMBootstrap.1.cs change set with<br>
SqueakSource VMMaker-dtl.104 (non-Croquet) on Squeak 3.8 on Linux. It works<br>
fine and I see no issues with backward compatibility for existing images.<br>
<br>
I am attaching the changes that were required to merge ClosureVMBootstrap with<br>
a non-Qwaq VMMaker. The changes were as follows:<br>
<br>
- Add missing ClassBlockClosure var to ObjectMemory<br>
- Merge class and instance var defs in Interpreter<br>
- Remove large integer stuff from #initializePrimitiveTable (is this for Croquet?)<br>
- Delete (now unused) primitiveObsoleteIndexedPrimitive<br>
<br>
The ClassBlockClosure definition in ObjectMemory was probably an accidental<br>
omission from the ClosureVMBootstrap change set, and the remainder of the<br>
changes are a straightforward merge for a different flavor of VMMaker.<br>
<br>
I have not yet progressed as far as getting the closure compiler loaded,<br>
but the closure-enabled VM seems to be trouble-free and fully backward<br>
compatible.<br>
