LLVMers, The 2.1 code freeze and branch creation is next Wednesday, September 12th at 9PM PDT. At this point in time, any major changes should be checked in. You are free to still commit changes to the tree, but please be extra cautious in what you commit and monitor the testers on platforms you are not able to test on. We would like things to remain as stable as possible up until the code freeze. Thanks, Tanya Lattner
