All, Please welcome Zhou Sheng <zhousheng00 at gmail.com> to the LLVM development community. Sheng is from Beijing and is a Masters student at the University there. Sheng and I will be working together on some significant changes to LLVM in the coming months. Our first task is to implement integer types without signs in LLVM. You can read Chris Lattner's notes on this change at this URL:http://nondot.org/~sabre/LLVMNotes/TypeSystemChanges.txt. Additionally, PR950 will track the implementation of this feature. You can keep track of our progress by going here: http://llvm.org/PR950 If you have any technical questions, please feel free to ask. Thanks, Reid.
