This can happen if the original interval has been broken into two disconnected parts. Ideally, we should be able to detect when the graph is disconnected and create separate intervals, but that code is not implemented yet. Example: Two basic blocks are both branching to a loop header. Our interval is defined in both basic blocks, and live into the loop along both edges. We decide to split the interval around the loop. The interval is split into an inside part and an outside part. The outside part now has two disconnected segments, one in each basic block. If we later decide to split the outside interval into single blocks, we get one interval per basic block and an empty dupli for the remainder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110976 91177308-0d34-0410-b5e6-96231b3b80d8 |
