These are "carefully crafted" to be backward-compatible. They will /not/ break an image for older VMs. There are three sets of changes:
1. remove primitives in LargePositiveInteger. These will make images slightly slower for certain benchmarks but won't break anything. 2. add special primitives for Float>>basicAt: at: basicAt:put: & at:put: that call super if they fail. They will fail on older VMs, hence these will make images slightly slower for certain benchmarks but won't break anything.
3. a new version of recreateSpecialObjectsArray that does not recreate the Character table. This will have no effect except for Cog, where it allows the VM to inline Character table access in the at: primitive.

which is clearly a bug in Cog. But I'd like to provide a flag/image-header-bit to allow one to specify either behaviour. i.e. fail float primitives that return NaNs or Infs, or return the relevant IEEE Inf/NaN. Andreas and I have just discussed this and he points out that while under ieee Inf and non-NaN results are bit-identical across platforms, NaNs are not. So for Croquet one really needs the code generator to arrange that float primitives that do return NaNs normalise those NaNs to a small set (e.g. a pair of a single +ve NaN & a single -ve NaN).

I yesterday downloaded XCode and built the Mac VM, only to find that it throws a clear error (LargeNegativeInteger is not compact at 5, can't continue) to the console. I told this to Eliot, but forgot to say it in the lists. I apologize. Anyway, for some reason, the win vm you posted, instead of giving the error and exiting cleanly, it does an invalid access and is terminated. Maybe you want to check that. BTW, most console messages (i.e. stdout) will be missed in these days of graphical shells. An OS dialog would be better. Thank Eliot, you and Teleplace for this great gift! This is a major milestone in the history of Squeak. Cheers, Juan Vuletich |

Morning all, I've pushed a number of changes into the iOS platform tree to enable you to build a Macintosh Cocoa V5 Cog VM. Well at least one that runs a few million byte codes before crashing. This also requires changes to the Cog branch, but that's part of the re-integration process. I have also built it as a Stack VM for the iPhone, that runs many more million bytecodes before tossing walkbacks on an unaltered image. Just a bit of image tinkering I think is needed there, plus a change to let complex events flow up out of the VM into the image, but again part of the re-integration process.
