Greetings,
welcome!
I though to take a look at transitioning a Cuis image into Spur format.
Great!
I presume there is a Smalltalk package which either runs in an old VM and writes the active image into the Spur format or code for a Spur image which reads the old format.
Yes, the Sour bootstrap is in the Cog package which is where I put support code for the VMMaker.oscog package, which is where the Cog VM lives.
[1] Where would I locate this code?
There are scripts to build a Cog VMMaker image and to run the Squeak 4.5 to Spur conversions in http://www.squeakvm.org/svn/squeak/branches/Cog/image http://www.squeakvm.org/svn/squeak/branches/Cog/image. See http://www.mirandabanda.org/cogblog/build-image/ http://www.mirandabanda.org/cogblog/build-image/
You'll want to redefine the GetGoodVM.sh or GetGoodSpurVM.sh scripts to run the relevant VM (if I recall the names correctly).
[2] Is there a Non-Cog Spur VM available? [Chromebook currently does page protect to disallow JIT]
Yes. In http://www.squeakvm.org/svn/squeak/branches/Cog/ http://www.squeakvm.org/svn/squeak/branches/Cog/imagespurstacksrc is a non-Cog Spur VM and there are pre-configured builds for it in eg http://www.squeakvm.org/svn/squeak/branches/Cog/ http://www.squeakvm.org/svn/squeak/branches/Cog/imagebuild.linux32x86/squeak.stack.spur
Note that VMMaker.oscog /should/ load and run in non-Spur squeak but I've not tried this for over a year now.
I needed to do some minor changes (very minor) for doing it in Pharo… I’m quite sure you will need them also for Squeak, but I do not think is necessary if what you want is to bootstrap a cuis-spur… you can always do it from a squeak-spur.

Thanks much, -KenD
Perhaps some time we can discuss what's necessary to get Cog VMs running on Chromebooks. Is it a matter of doing the entry into machine code appropriately or is there a deal breaker or...?
