Cameron Zwarich 8fbbdca45c Set NumSignBits to 1 if KnownZero/KnownOne are being zero extended. In theory it ... is possible to do better if the high bit is set in either KnownZero/KnownOne, but in practice NumSignBits is always 1 when we are zero extending because nothing is known about that register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126465 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-25 01:11:01 +00:00
