Signedness Elminiation

All,

Please welcome Zhou Sheng <zhousheng00@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.
