As a result, we run all of our optimization passes in a loop until the shader code stabilizes.

Re: [Mesa-dev] Google Summer of Code ideas needed
Hi, If LLVM backend development is allowed, maybe a student could work on improving VLIW5 scheduling for R600 hardware. So far I focused on VLIW4 architecture, but extending the scheduler to support Trans ALU wouldn't be too hard. This would require a way to represent Trans slot compatibility for instruction in R600Instructions.td, check for additionnal constants read/literals limitation on this slot, and modifying a couple of functions inside R600MachineScheduler.cpp. This may look like a short task but the student would also need some time to get used to all the tools we use, like piglit, and to understand llvm codebase. - Mail original - De : Tom Stellard t...@stellard.net À : mesa-dev@lists.freedesktop.org Cc : Envoyé le : Mercredi 13 mars 2013 18h11 Objet : [Mesa-dev] Google Summer of Code ideas needed Hi, It's time again for Google Summer of Code, so we need to start updating the X.Org ideas page (http://www.x.org/wiki/SummerOfCodeIdeas) with new ideas.
