Hi Bryce,
I am very interested in Exupery. Once I have wrapped up developing and debugging my little EChat application in SqueakElib, I will be more than happy to help debug Exupery, if I can understand it. It will probably be after Thanksgiving holidays next week, before I'll be able to load and run it. Thanks for your help. Once I get some familiarity, I may ask for further details regarding larger contexts and the extra long jump bytecodes.
Cheers, Rob

Hi, Thanks for your interest in Exupery. First, Exupery will probably provide a speed up now but it will also cause crashed and bugs. I'd suggest delaying integration until Exupery is more stable..
If you're interested in helping to debug Exupery, that would be great. At this stage, it's probably more sensible to talk, use Exupery as an excuse to delay optimising but keep your options open. Building one experiment on top of another multiplies risks a little too much for my tastes. From what I understand, it's really the potential of full method inlining that should be most interesting for your project but that's not planned until after Exupery's 1.0 release.
That said, if you're interested in knowing what Exupery can do now, or should be able to do in the future feel free to ask or play with it. There's prebuilt VM's for all major platforms though the Mac one is compiled without C compiler optimisation here:

Hi All!
I have reached step 2.4 in my SqueakElib plan documented here: http://wiki.squeak.org/squeak/6011, but I don't know anything about Exupery. I suppose my first question is whether I am right in assuming that I will see speedups if I incorporate Exupery?
My next question is related to the work I did in steps 1.3, 1.4, and 1.5. I modified the VM to use larger contexts (80+7), to add extra long jump bytecodes for jump:, jumpIfTrue: and jumpIfFalse:, and to add bytecodes for doing receiver class tests. Will these additions cause problems with Exupery?
It'll take some work but not too much. Exupery has it's own context classes which will need to be enlarged. This should be fairly easy to do. The same with adding extra log jump bytecodes.
If all is ok so far, I want to build my modified Windows VM with Exupery, so I am reading http://wiki.squeak.org/squeak/5904. I am confused as to which VMMaker I can use to build. I currently have VMMaker-tpr.58.mcz loaded. Can you confirm that I need to either overwrite this VMMaker with the one from the Exupery repository or that I need to build fresh with the one from the Exupery repository? Also, where is the VMMaker from the Exupery repository - where is the Exupery repository? Finally, what is the best Subversion client for Windows and how do I connect to this Exupery repository?
Instructions on building on Windows are here: http://wiki.squeak.org/squeak/5904
I've only done builds on Linux.
The Exupery source is held on SqueakSource here: http://www.squeaksource.com/Exupery

P.S. I'd suggest using the latest Exupery version from SqueakSource published today rather than the released version. I just fixed an important bug that makes it much more stable. _______________________________________________ Exupery mailing list Exupery@lists.squeakfoundation.org http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/exupery
