Dale, Yeah that is correct, so that isn't the problem, not sure why I was thinking it is. The !MRI->use_no_dbg_empty(Reg) seems to be correct and the problem is LivePhysRegs[Reg] always returning false. I've looked into this more and there is a part where I'm working with physical registers. If there is a function call, there is a copy from virtual register space to the functions that are expected to be p...

I've recently sync'd to a newer version of LLVM(Apple branch 2326 from Apple branch 2323.8) that changed the interface to addCommonCodeGenPasses which caused the default implementation to be executed instead of my overriding implementation. This default implementation has DeadMachineInstructionElim pass enabled, which is causing havoc with my backend. Before entering this pass, everything
