David Majnemer c86bdc73e8 InstCombine: Don't unconditionally preserve 'nsw' when shrinking constants ... Consider: %add = add nsw i32 %a, -16777216 %and = and i32 %add, 255 Regardless of whether or not we demand the sign bit of %add, we cannot replace -16777216 with 2130706432 without also removing 'nsw' from the instruction. This fixes PR20377. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216261 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-22 07:56:32 +00:00
