[LLVMdev] How to get register liveness information for each MachineBasicBlock

[Dongrui She]

Hi all,

I try to print the live-in and live-out registers for each basic block in a
backend for my own target.
And I can get a list of live-in registers directly in MachineBasicBlock.

Is there a quick way to also get the list of live-out registers without
redoing the analysis. I think
this information is computed and stored somewhere.
