Hi all! I've been tinkering with LLVM's code-base for a few days, hoping to start on one of the ideas mentioned in the "Open Projects" page (I was told 'Improving the current system'/'Miscellaneous Improvements'/5 would be a good start). While I was at it, I also took a stab at finishing up one of the TODOs. I've attached the patch for review. --

Hi As I understand live variable analysis will set the def/kill properties of operands. In that case, is it still needed to set the kill flags when possible during lowering? thanks dz
