Implement the sadd_with_overflow intrinsic. This is converted into "ISD::ADDO". ISD::ADDO is lowered into a target-independent form that does the addition and then checks if the result is less than one of the operands. (If it is, then there was an overflow.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59779 91177308-0d34-0410-b5e6-96231b3b80d8
