The Flex IDE uses the Flex SDK to do compilation. The format of the bytecode in a SWF is described in this document: http://www.adobe.com/devnet/actionscript/articles/avm2overview.pdf Flash CS3 produces similar bytecode, but I don't know whether it uses the same AS3 compiler as the Flex SDK does. And I don't know what haxe is. - Gordon
