Bill Wendling 5d026e47c1 Redo the arithmetic with overflow architecture. I was changing the semantics of ... ISD::ADD to emit an implicit EFLAGS. This was horribly broken. Instead, replace the intrinsic with an ISD::SADDO node. Then custom lower that into an X86ISD::ADD node with a associated SETCC that checks the correct condition code (overflow or carry). Then that gets lowered into the correct X86::ADDOvf instruction. Similar for SUB and MUL instructions. llvm-svn: 60915		2008-12-12 00:56:36 +00:00
