Folks -
I've prepared a version of Squeak 4.1 for those of you who are not into recompiling VMs yourself. You can download it from:
http://squeakvm.org/win32/experimental/CogSqueak4.1.zip
The package contains a freshly compiled Cog VM for Windows and an updated Squeak4.1 image. Some things to note:
* Once you save the image with Cog, you can only run it with Cog. So load your benchmarks into the image *before* you launch it with Cog (i.e., to ensure you're comparing apples with apples you should use the same image)
* There are some changes that are required in the image. Most importantly, some LargeInt primitives need to be removed: #(= bitAnd: bitOr: bitShift: bitXor: ~=) do:[:sel| LargePositiveInteger removeSelector: sel. ].
This will be necessary for any images you want to run with Cog. There are also some other changes but they are not critical (i.e., don't crash the VM).
Enjoy, - Andreas
