David Majnemer 3bd87826e5 [InstCombine] Clear out nsw/nuw if we modify computation in the chain ... An nsw/nuw operation relies on the values feeding into it to not overflow if 'poison' is not to be produced. This means that optimizations which make modifications to the bottom of a chain (like SimplifyDemandedBits) must strip out nsw/nuw if they cannot ensure that they will be preserved. This fixes PR23309. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235544 91177308-0d34-0410-b5e6-96231b3b80d8		2015-04-22 20:59:28 +00:00
