Hi all,
I thought some of you might be interested to know that TransGaming SwiftShader now features a back-end based on LLVM. SwiftShader is a high-performance 3D software rendering toolkit (http://transgaming.com/business/swiftshader/technology/). It has recently been licensed by Adobe for the Flash Molehill 3D API (http://labs.adobe.com/technologies/flash/molehill/).
That version doesn’t use LLVM though; it uses the much smaller and faster SwiftAsm back-end. However, the Direct3D 9 demo available from the TransGaming website fully relies on LLVM for dynamic code generation. You may be pleased to know that the generated code performs the same or faster than hand-tuned dynamically generated assembly code. LLVM’s optimization passes have been indispensable to achieve exceptional Shader Model 3.0 performance. On top of LLVM we’re using another abstraction layer, called Reactor, which defines a powerful high-level language.
If you decide to try out the demo, make sure to check out the SwiftConfig functionality. While running a Direct3D 9 application with SwiftShader in windowed mode, you can interactively change its settings by opening http://localhost:8080/swiftconfig in your browser. These settings include some LLVM optimization passes that can be selected or reordered!
So finally you know what my secret vector intensive project was. 
I’d like to thank all LLVM developers for providing this incredibly versatile compiler infrastructure, and I hope I’ll be able to contribute some more myself in the near future. If you have any questions about the use of LLVM in SwiftShader, feel free to ask!
Cheers,
Nicolas Capens
