- LowerXADDO lowers [SU]ADDO into an ADD with an implicit EFLAGS define. The EFLAGS are fed into a SETCC node which has the conditional COND_O or COND_C, depending on the type of ADDO requested. - LowerBRCOND now recognizes if it's coming from a SETCC node with COND_O or COND_C set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60388 91177308-0d34-0410-b5e6-96231b3b80d8
