Android Cog VM/Pharo Builds at INRIA Jenkins

Hi,

Cog VM exists in two flavors: one is a pure interpreter (aka StackVM
[1]) which is easy to port; another is JIT [2] (currently exists for
x86, and some development of ARM version can be seen).

But even non-JIT Cog has better support of closures than the classic
Squeak VM has (or had, at least per [3], maybe these days this is
fixed in the classic VM as well)

I just think that CogVM and StackVM are separeted Vms-names for new Eliot VMs.
And CogVM is always related to JIT VM.

Eliot implemented the closure support for the classic VM also, so all
current VMs provide closure support.
