Dan Gohman	4b46cbfc23	Mark dead physregdefs dead immediately. This helps MachineSink and ... MachineLICM and other things which run before LiveVariables is run. llvm-svn: 85360	2009-10-28 01:13:53 +00:00
Dan Gohman	b8120770b4	Create a new InstrEmitter class for translating SelectionDAG nodes ... into MachineInstrs. This is mostly just moving the code from ScheduleDAGSDNodesEmit.cpp into a new class. This decouples MachineInstr emitting from scheduling. llvm-svn: 83699	2009-10-10 01:32:21 +00:00
