</div>FYI a number of constants including BytesPerWord and BaseHeaderSize<br>
are replaced by message sends in VMM trunk as part of the changes<br>
that put this all under compile time control (as opposed to defining<br>
at code generation time). It would probably be good to apply these<br>
changes to oscog at some point also, although I cannot realistically<br>
offer to put any time into it right now.<br></blockquote><div><br></div><div>Agreed. I was reluctant to do this earlier. Alas while it might allow one to run e.g. a 64-bit ObjectMemory alongside a 32bit ObjectMemory, the pervasive use of class and pool variables means its not possible to run an ObjectMemory against a SpurMemoryManager. I'd rather change the code base as little as possible than risk breaking things, so I'm happy to live with e.g. the compact class indices staying in class/pool vars.</div>
<div><br></div><div>BTW, David, I implemented NewObjectMemory>>eeInstantiateClassIndex:format:numSlots: (in VMMaker.oscog-eem.369) which needs to set the Size4Bit. It contains a comment asking you to check the code :-). I wonder if, in your copious free time, you might do just that? No hurry, and indeed I hope to render ObjectMemory and NewObjectMemory obsolete asap :-).</div>
