FYI. I can't remember if we talked with Alessandro already in the past about joining our efforts. Alessandro, do you remember about it ?

Well, although I've not been actively publishing news about it for several months now, work has been going on full speed ahead. As part of my bachelor thesis I've greatly enhanced and tested my Actionscript 3.0 JIT engine based on LLVM. For the last week or so I've been working to make the Virtual Machine stable enough to run stuff based on the Flex framework. The test application I've been working on is mostly empty, just a bare mx.core.Application with a VBox children, generated using the following mxml source. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; horizontalAlign="center" verticalAlign="middle"> <mx:VBox x="0" y="0" width="201" height="200" backgroundColor="0x0080C0" alpha="0.8"/> </mx:Application> This may appear trivial, but I can assure you that a huge deal of work is done by the flex framework to run this. In some days I'll release a new technical demo but, as always, code is already available using git from the repository git://lightspark.git.sourceforge.net/gitroot/lightspark/lightspark I think that having the Flex framework running is a great sign that the Virtual Machine is stable enough to move the project from a pre-alpha to an alpha status. Moreover, now I think the design itself is good enough for other people to join the effort, as I'll never be able to finish the work all by myself. I'm looking for people with good C++/OpenGL programming experience. With this release preliminary support for Windows has been added, so people from both the Windows and Linux world may join. Right now there are some major stuff to work on: -) Write an Actionscript interpreter: since the beginning lightspark was based on a JIT engine to run Actionscript, as that was also the main focus of my thesis. But actually is very sensible to set up an interpreter to run code that is not used often, such as initialization code. Right now the whole system is pretty slow, but more than 90% of the time is spent inside LLVM Just in time compiler. Moreover, most of the code is compiled and then executed only once, which results in a waste of time and memory. -) Optimize, and maybe redesign, the graphics rendering system. I'm not an OpenGL guru (although definitely not a newbie), so advices from people more expert than me would be pretty useful. -) Make the Actionscript engine pass all the conformance tests included with the tamarin source code -) Add support for Actionscript exceptions. That's the only major feature of the language still totally unsupported.
