Eli Friedman 268637ed0f Implement expansion in type legalization for add/sub with overflow. The ... expansion is the same as that used by LegalizeDAG. The resulting code sucks in terms of performance/codesize on x86-32 for a 64-bit operation; I haven't looked into whether different expansions might be better in general. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105378 91177308-0d34-0410-b5e6-96231b3b80d8		2010-06-03 03:49:50 +00:00
