...with the concepts behind auto-vectorization, I haven't implemented an auto-vectorizer before. I'm author of and contributor to several smaller open source projects. I appreciate any suggestions and would be very excited if someone is interested in mentoring this. -- Best regards, Andreas Bolka

Hi, Does anyone know if there is any existing code I can use to do a loop-carried dependence analysis for LLVM IR programs? I searched the mailing-list archive and it seems like someone planned to implement a loop dependence analysis pass in March. I'm just wondering if this project is ongoing/finished or if there is other projects that may have the code I'm interested in. Thanks!

Hi, As a Linux package maintainer I tend to follow LLVM mostly towards the end of each release cycle; nevertheless, I sometimes need to keep track of multiple LLVM branches at the same time. It would be great if I could use Git's SVN to clone the repository once, and then have the full version history available locally in a compact format. As a bonus, this will reduce the load on the server

Please don't do that :) Let me add to what Anton said: I can only speak for
