Internet News   Internet News : Adobe Opens Source Of The ActionScript Virtual Machine
   posted by ShadesOfGrey on 7-Nov-2006 21:25:37 (1917 reads)
Adobe have opened the source of their ActionScript Virtual Machine and contributed the code to the Mozilla Project.
Since that code is under the MPL/GPL/LGPL, could this code find its way into some Amiga browsers?

Further information can be found in this article on Ars Technica and the Mozilla Tamarin Project home page.

Does it generate code for PowerPC? If not it is of no use to us.

A virtual machine is not a compiler, it is an engine that converts system-calls directed at the virtual machine into system-calls specific to the hardware and OS that the virtual machine is running on top of.

The article said that the VM supports JIT compilation. This is certainly system-specific.

@Samurai_Crow:

AFAIK no: compilation into the virtual meta-code is meant here.

BTW: nice thingy but actually I began to disable Flash in my browsers since it's mainly used by banners and advertising.

What I thought would be of most interest were these statements in the Ars Technica article:

Quote:
Mozilla has responded to Adobe's contribution by creating the Tamarin Project. Named after a species of tiny arboreal monkeys, the project aims to develop a complete ECMAScript 4 implementation based on Adobe's virtual machine.


and

Quote:
The availability of an open source ECMAScript 4 implementation would promote adoption of the standard and could potentially stimulate use of JavaScript 2, which is based on ECMAScript 4.


I don't see how Amiga browsers would not benefit from implementing ECMAScript 4. The impression I get is that as the AVM2 is integrated into SpiderMonkey, it will be further developed. I see the potential for a stand alone VM that could provide JavaScript 2 interpretation via a browser plug-in... At least on the Amiga platform.
