Thanks. One question though. Should getMBBFromIndex() assert if given an index out of the range or simply returns a NULL pointer? I would think the later makes it a bit more friendly.

On the other hand I want to mention the following pros...

...ion of this algorithm and have a few hopefully rather simple questions: 1) What is the easiest way to understand which MBB a given instruction index belongs to? All the required information is available in the MBB2IdxMap of the LiveIntervalAnalysis class. Would it be useful to add a small function getMBBFromIndex() to this class? 2) Is there any simple way to iterate over all instructions, where a given live interval is live? This functionality is required by many register allocation algorithms. I think having some special iterator functions for that in the LiveIntervalAnalysis class could be very useful f...

Hello to all LLVM Developers. Given a object from a LiveInterval class, is there any way to know if this Live Interval is part or is inside a loop?

Call "getParent()" on the MachineInstr. -bw
