If the NUW bit is set for 0 - Y, we know that all values for Y other than 0 would produce a poison value. This allows us to replace (0 - Y) with 0 in the expression (X - (0 - Y)) which will ultimately leave us with X. This partially fixes PR20189. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214384 91177308-0d34-0410-b5e6-96231b3b80d8 |
