I done writing a small overview of code generator changes.<br>
You can find it there: <a href="http://squeakvm.org/~sig/hydravm/codegen.html" target="_blank">http://squeakvm.org/~sig/hydravm/codegen.html</a><br>

Definitely, we should merge efforts :)<br>
Well, your changes is not backwards compatible with current squeak<br>
images, while Hydra can run them w/o problems.</blockquote><div><br></div><div>My changes _are_ backward compatible. I add five new bytecodes taken from the unused experimental bytecodes. The existing bytecodes are still supported and the VM runs both closures and BlockContext blocks side-by-side.</div>
<div><br></div><div>I have another VM in the works which does context-to-stack mapping and that only runs closures. But I have yet to publish this or the Slang changes that go with it.</div><div><br></div><div><br></div>

This is the reason, why i want to release them now - at least in<br>
binary form. So people may try run it and report problems found.<br>
<br>
So here is update.<br>
----<br>
<br>
VMMaker and HydraVM packages is now at squeaksource.<br>
<br>
MCHttpRepository<br>
location: '<a href="http://www.squeaksource.com/HydraVM" target="_blank">http://www.squeaksource.com/HydraVM</a>'<br>

<br>
The platform sources are located here:<br>
<br>
<a href="http://squeakvm.org/svn/squeak/branches/HydraVM" target="_blank">http://squeakvm.org/svn/squeak/branches/HydraVM</a><br>
<br>
I also wanted to put binaries to <a href="http://ftp.squeak.org/HydraVM" target="_blank">ftp.squeak.org/HydraVM</a>, but forgot<br>
the password :)<br>
Ken, can you remind me please?<br>
<br>
<br>
Changes in last update:<br>
<br>
- fixed bug with queues<br>
- revised many plugins which can be now built with VM. It now builds<br>
with 100% plugins which coming by default with VMMaker package (if i<br>
didn't miss anything).<br>
