...ir supperregister's interval contains. So is this just supposed to be a conservative update for the purposes of coalescing? In any event, it seems not to be working right if what you describe is supposed to be happening. Given the two intervals in my example, which should happen with the two overlappring ranges %reg1026: [458,5168:0 [0]) %reg15: [938,942:1 [0]) My assumption was that after MergeInClobberRanges that %reg15 would contain [458,5168:0 [0]). But it doesn't. -Dave
