<p>Bonjour Clément, quoi de neuf? Eliot?<br/>
</p>
<p>This is all very interesting news. I am sad to hear that 64-bit
will need to be built. Then I decide not to be sad, that it is an
opportunity to build a good foundation. Therefore, I request of
the vm-dev list, who is a part of the Sista Team? Lots of good
work to be done. Let us get it on! PortPortPort.<br/>
<br/>
I bring Eliot to the email to mention that yes indeed I would like
to deploy ParrotTalk/Raven upon a Sista 64-bit vm. I believe the
first step is to form a team of interested parties. I am willing
to spend some time, though my focus is porting SSL, ATM.</p>
<p>Which way is which what?</p>
<p>Kindly,<br/>
mumbles<br/>

<div dir="ltr">Hi Robert,<br/>
<br/>
I worked on sista and I don't think I have ever tried it on 64
bits. I run my experiments on x86. My expectation for 64 bits is
that you have to write build files inspired from the 32 bits
<div>sista.spur and the 64 bits cog.spur files. Then you have to
run it in the VM simulator and fix the various few problems
you see (likely a few instructions are not implemented in the </div>
<div>x64 back-end). Then you can build a system. It's not so
much work.
<div><br/>
<div>There was a released alpha version of Sista [1], which
I used to run the benchmark of a research paper [2]. If
you compile a VM with sources from that time (recent
sources have difference </div>
<div>that will break it), and follow the guidelines from the
blog post [1], you should be able to reproduce the
benchmark results from the paper. <br/>
<br/>
As I remember it, most benchmarks run without crashes at
1.5x and the development tools could be run for a while
without crashes. Debugging and on-the-fly code changes in
sista are </div>
<div>only partially implemented (there's the potential to do
it, but one has to implement it). I would say it is
currently in a similar state as the strongtalk VM [3],
while being compatible with </div>
<div>Squeak and other Cog clients. </div>
<div><br/>
</div>
<div>I don't know what you mean by operational. If you're
looking to experiment with it, tweak it to run some
benchmarks, then you should be able to do it. If you're
looking to deploy an application </div>
<div>on a production VM, then significant work is left to do
so (discuss directly with Eliot if that is the case). </div>
<div><br/>
</div>
<div>Have fun with the project :-)</div>

I understand that Sista is operational. I would like to try.
How can I <br/>
build a Sista vm? I went to linux64x64/squeak.sista.spur and
there is a <br/>
file there NotYetImplemented.<br/>
<br/>
I appreciate any guidance.<br/>
