Jakob Stoklund Olesen 7ebc4d63db Add MachineInstr::readsVirtualRegister() in preparation for proper handling of ... partial redefines. We are going to treat a partial redefine of a virtual register as a read-modify-write: %reg1024:6 = OP Unless the register is fully clobbered: %reg1024:6 = OP, %reg1024<imp-def> MachineInstr::readsVirtualRegister() knows the difference. The first case is a read, the second isn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104149 91177308-0d34-0410-b5e6-96231b3b80d8		2010-05-19 20:36:22 +00:00
