Hi Tim,

Thanks for reviewing. The code is mainly based on ARM' version
(ARMISelLowering).

Thanks,

Hi Weiming,

and RETURNADDR.

I think the patch looks fine (I was confused for a bit over just what
MachineFunction::addLiveIn does, but it seems sufficient for the job at
hand). Thanks for implementing that!

Cheers.

Tim.
